While these might be big fancy titles, the actual concepts they represent are actually much more simple, and probably something you already do to some extent subconsciously.  The whole idea behind these concepts is to reduce GA accidents.  The diagram above shows where GA accidents are most likely to occur, and given the high rate of occurrence on takeoff, as well as maneuvering and landing, it seems logical we could all benefit from enhancing our skill making decisions and utilizing resources in these critical phases of flight. First, let’s talk about CRM and SRM.

CRM

While CRM focuses on pilots operating in crew environments, many of the concepts apply to single-pilot operations. Many CRM principles have been successfully applied to single-pilot aircraft and led to the development of Single-Pilot Resource Management (SRM).  The main idea behind CRM is to use all the available resources available to you in the flight deck/cockpit.  The video at the beginning of this TOPIC describes CRM in-depth and more importantly, gives you examples of how to actually apply it.

SRM

SRM is defined as the art and science of managing all the resources (both on-board the aircraft and from outside sources) available to a single pilot (prior to and during flight) to ensure the successful outcome of the flight. SRM includes the concepts of ADM, risk management (RM), task management (TM), automation management (AM), controlled flight into terrain (CFIT) awareness, and situational awareness (SA). SRM training helps the pilot maintain situational awareness by managing the automation and associated aircraft control and navigation tasks. This enables the pilot to accurately assess and manage risk and make accurate and timely decisions. SRM is all about helping pilots learn how to gather information, analyze it, and make decisions. Although the flight is coordinated by a single person and not an onboard flight crew, the use of available resources such as auto-pilot and air traffic control (ATC) replicates the principles of CRM.  To sum this up: think of creative ways to manage your resources as effectively as possible when you are the only pilot in the airplane (use ATC to your advantage, use suction cups to hold up a clipboard with charts on it, organize your flight bag so you can quickly find what you are looking for without taking your attention away from flying, etc.).

Aeronautical Decision Making

ADM really just refers to any decision you make regarding flying either before, during, or after your flight.  Of course, the FAA does have specific guidance to help ensure you are making good decisions at all times.  We’ll go ahead and take a look at some mnemonic devices and checklists the FAA would like you to use anytime you are going to be flying.

IMSAFE

One of the best ways single pilots can mitigate risk is to use the IMSAFE checklist to determine physical and mental readiness for flying:

  1. Illness—Am I sick? Illness is an obvious pilot risk.
  2. Medication—Am I taking any medicines that might affect my judgment or make me drowsy?
  3. Stress—Am I under psychological pressure from the job? Do I have money, health, or family problems? Stress causes concentration and performance problems. While the regulations list medical conditions that require grounding, stress is not among them. The pilot should consider the effects of stress on performance.
  4. Alcohol—Have I been drinking within 8 hours? Within 24 hours? As little as one ounce of liquor, one bottle of beer, or four ounces of wine can impair flying skills. Alcohol also renders a pilot more susceptible to disorientation and hypoxia.
  5. Fatigue—Am I tired and not adequately rested? Fatigue continues to be one of the most insidious hazards to flight safety, as it may not be apparent to a pilot until serious errors are made.
  6. Emotion—Am I emotionally upset?

After working through this checklist and answering these questions you should have a better idea if you are really fit for flight or if it might be best to stick to playing flight simulator today instead.

PAVE

Pave is another checklist you should use before flying to evaluate yourself, the airplane, the flight in general, and your mental state.

One of the most important concepts that safe pilots understand is the difference between what is “legal” in terms of the regulations, and what is “smart” or “safe” in terms of pilot experience and proficiency.  The PAVE checklist can hopefully help you to begin to differentiate between “legal” and “safe”, often what is actually legal is not safe.

  1. P = Pilot in Command (PIC)         The pilot is one of the risk factors in a flight. The pilot must ask, “Am I ready for this trip?” in terms of experience, recency, currency, physical, and emotional condition. The IMSAFE checklist provides the answers.
  2. A = Aircraft       What limitations will the aircraft impose upon the trip? Ask the following questions:
    • Is this the right aircraft for the flight?
    • Am I familiar with and current in this aircraft?
    • Aircraft performance figures and the AFM are based on a brand new aircraft flown by a professional test pilot. Keep that in mind while assessing personal and aircraft performance.
    • Is this aircraft equipped for the flight? Instruments? Lights? Navigation and communication equipment adequate?
    • Can this aircraft use the runways available for the trip with an adequate margin of safety under the conditions to be flown?
    • Can this aircraft carry the planned load?
    • Can this aircraft operate at the altitudes needed for the trip?
    • Does this aircraft have sufficient fuel capacity, with reserves, for trip legs planned?
    • Does the fuel quantity delivered match the fuel quantity ordered?
  3. V = EnVironment         Weather is a major environmental consideration. Earlier it was suggested pilots set their own personal minimums, especially when it comes to weather. As pilots evaluate the weather for a particular flight, they should consider the following:
    • What is the current ceiling and visibility? In mountainous terrain, consider having higher minimums for ceiling and visibility, particularly if the terrain is unfamiliar. • Consider the possibility that the weather may be different than forecast. Have alternative plans and be ready and willing to divert, should an unexpected change occur.
    • Consider the winds at the airports being used and the strength of the crosswind component.
    • If flying in mountainous terrain, consider whether there are strong winds aloft. Strong winds in mountainous terrain can cause severe turbulence and downdrafts and be very hazardous for aircraft even when there is no other significant weather.
    • Are there any thunderstorms present or forecast?
    • If there are clouds, is there any icing, current or forecast? What is the temperature/dew point spread and the current temperature at altitude? Can descent be made safely all along the route?
    • If icing conditions are encountered, is the pilot experienced at operating the aircraft’s de-icing or anti-icing equipment? Is this equipment in good condition and functional? For what icing conditions is the aircraft rated, if any?
    • Evaluation of terrain is another important component of analyzing the flight environment.
    • To avoid terrain and obstacles, especially at night or in low visibility, determine safe altitudes in advance by using the altitudes shown on VFR and IFR charts during preflight planning.
    • Use maximum elevation figures (MEFs) and other easily obtainable data to minimize chances of an inflight collision with terrain or obstacles.
    • What lights are available at the destination and alternate airports? VASI/PAPI or ILS glideslope guidance? Is the terminal airport equipped with them? Are they working? Will the pilot need to use the radio to activate the airport lights?
    • Check the Notices to Airmen (NOTAM) for closed runways or airports. Look for runway or beacon lights out, nearby towers, etc.
    • Choose the flight route wisely. An engine failure gives the nearby airports supreme importance.
    • Are there shorter or obstructed fields at the destination and/or alternate airports?
    • If the trip is over remote areas, is there appropriate clothing, water, and survival gear onboard in the event of a forced landing?
    • If the trip includes flying over water or unpopulated areas with the chance of losing visual reference to the horizon, the pilot must be prepared to fly IFR (if you are not instrument rated or the aircraft is not instrument equiped then this is a problem!).
    • Check the airspace and any temporary flight restriction (TFRs) along the route of flight. Nighttime flying requires special consideration.
    • If the trip includes flying at night over water or unpopulated areas with the chance of losing visual reference to the horizon, the pilot must be prepared to fly IFR. • Will the flight conditions allow a safe emergency landing at night?
    • Perform preflight check of all aircraft lights, interior and exterior, for a night flight. Carry at least two flashlights—one for exterior preflight and a smaller one that can be dimmed and kept nearby.
  4. E = External Pressures        External pressures are influences external to the flight that create a sense of pressure to complete a flight—often at the expense of safety. Factors that can be external pressures include the following:
    • Someone waiting at the airport for the flight’s arrival
    • A passenger the pilot does not want to disappoint
    • The desire to demonstrate pilot qualifications
    • The desire to impress someone (Probably the two most dangerous words in aviation are “Watch this!”)
    • The desire to satisfy a specific personal goal (“gethome-itis,” “get-there-itis,” and “let’s-go-itis”)
    • The pilot’s general goal-completion orientation
    • Emotional pressure associated with acknowledging that skill and experience levels may be lower than a pilot would like them to be. Pride can be a powerful external factor!
      • Managing External Pressures Management of external pressure is the single most important key to risk management because it is the one risk factor category that can cause a pilot to ignore all the other risk factors. External pressures put time-related pressure on the pilot and figure into a majority of accidents. The use of personal standard operating procedures (SOPs) is one way to manage external pressures. The goal is to supply a release for the external pressures of a flight. These procedures include but are not limited to:
        • Allow time on a trip for an extra fuel stop or to make an unexpected landing because of weather.
        • Have alternate plans for a late arrival or make backup airline reservations for must-be-there trips.
        • For really important trips, plan to leave early enough so that there would still be time to drive to the destination, if necessary.
        • Advise those who are waiting at the destination that the arrival may be delayed. Know how to notify them when delays are encountered.
        • Manage passengers’ expectations. Make sure passengers know that they might not arrive on a firm schedule, and if they must arrive by a certain time, they should make alternative plans.
        • Eliminate pressure to return home, even on a casual day flight, by carrying a small overnight kit containing prescriptions, contact lens solutions, toiletries, or other necessities on every flight. The key to managing external pressure is to be ready for and accept delays. Remember that people get delayed when traveling on airlines, driving a car, or taking a bus. The pilot’s goal is to manage risk, not create hazards.

Other Checklists

At the end of the day you will have to use what works for you, but using what the FAA provides is a great starting point.  Consider printing out the below checklists and taping them to the back of your kneeboard to keep handy when planning and when in flight.

Federal Aviation Regulations

Hope you’re still awake there guys!  Understandably the “book work” side of things with ADM, Medical Factors, etc. isn’t quite as exciting as watching videos on flying around busy airspace, but it is what will ultimately keep you safe and legal in the sky.  Below we have some more rules for you to follow.  Most important here is you understand these rules, why they exist, and how to apply them.  If you have questions on any of the regulations we discuss below, leave them in the comments below and I’m sure someone can explain to you why we have that rule.  REMEMBER: just about every rule out there in flying is written in blood (meaning the rule exists because one or usually more pilots killed themselves and others, and the rule is meant to try to prevent that from happening again, thus if you follow the rules, you are more likely to be safe!)

General

Aircraft Operating Category

Different from the categories and classes we talked about before, the category the aircraft is operating in depends on what it is certified to do as well as the weight and CG it is at (see the specific airplane’s POH to see the exact details).  The Categories are:

  • Tansport = Airliners
  • Normal = Max Takeoff Weight of 12,500lbs Load limit: +3.8G / -1.52G Limit (see FAR 23.3 for more info)
  • Utility = Max Takeoff Weight of 12,500lbs Load limit: +4.2G / -1.76G Limit (see FAR 23.3 for more info)
  • Limited
  • Restricted = Cannot be operated over densely populated areas, congested airways, or near a busy airport where passenger transport is conducted
  • Acrobatic
  • Provisional

(don’t worry too much about the bottom 4 categories as a private pilot)

Part 21

Airworthiness Certificates

Airworthiness Certificates remain in effect as long as maintenance and alteration of the aircraft are performed per the Federal Aviation Regulations.

Part 39

ADs (Airworthiness Directives)

AD’s are issued under part 39 of the FARs to correct unsafe conditions found in an airplane or its parts.  They are issued by the FAA when the FAA or manufacture finds repeat problems occurring in a certain model aircraft.  You find out about ADs either by mail or most likely through your mechanic who checks the “bi-weekly” or AD database on the FAA website that is updated every two weeks.  ADs are mandatory and the owner typically bears the expense of complying with the AD (buying new parts, paying for the required inspection, etc.)

It is the Owner / Operators responsibility to ensure compliance with ADs (just because you don’t own the airplane and you rent it, you as PIC are still the operator!  You need to check maintenance logs before going flying).

Part 43

Preventative Maintenance

A person who holds a pilot certificate may perform preventative maintenance on any airplane owned or operated by that pilot that is not used in air carrier services.  Basically, you can replace light bulbs and top up some of the fluids, it is for simple or minor preservation between regular maintenance inspections.  To see a whole list of what you can do, reference 14CFR 43.3(g) and Part 43 appendix (a).

Return To Service

To return an aircraft to service after any maintenance the appropriate log entries must be made by the person performing the work.  If it was preventative maintenance, then at least a private pilot, if more complex, then the A&P mechanic or IA mechanic must make the log entries.

Maintenance Records

After maintenance is performed, the signature, certificate number, type of certificate held by the person approving the work, the date, and a description of the work performed must be entered in the aircraft maintenance records (logbook).

Part 47

Registration

Registration is good for 3 years expiring on the last day of the month it was issued 36 months later.  If you sell an aircraft, 14CFR47.41(b) requires you to mail the registration back to the FAA with the information of the buyer filled in on the backside.

Part 61

Documents

When acting as PIC or as a required crew member you must have a valid pilot certificate and current and appropriate medical certificate in your personal possession or readily accessible in the aircraft.  You must present your documents upon the request of the Administrator of the FAA or his or her representative, the NTSB, or any state, federal, or local law enforcement officer.

Offense involving alcohol or drugs

Each person holding a certificate under Part 61 (pilot certificate or medical certificate) shall provide a written report of each motor vehicle action involving alcohol or drugs to the FAA, Civil Aviation Security Division, no later than 60 days after the motor vehicle action.

Medical Certificates Requirement and Duration

Who needs what medical:

  • 1st class = airline pilots
  • 2nd class = pilots working for hire (charter pilots, banner tow pilots, etc.)
  • 3rd class = pilots not being paid to fly (private pilots, sport pilots, and CFIs, because according to the FAA, CFIs are paid to teach, not to fly).

Duration:

  • 1st class = 6mo over 40 years old, 12mo under 40 years old
  • 2nd class = 12mo
  • 3rd class = 24mo over 40 years old, 60mo under 40 years old
  • Duration is all “calendar months” meaning the medical will expire on the last day of the month it was issued. (i.e. you get your 3rd class medical October 5th 2018 and you are over 40 years old, it expires October 31st, 2020)

Endorsements, Type Rating, Etc

To act as PIC in a complex airplane you must receive and log ground and flight instruction from an authorized instructor.

  • Complex airplane is defined as: airplane having retractable landing gear, flaps, and a controllable pitch propeller.

To act as PIC in a high performance airplane you must receive and log ground and flight instruction from an authorized instructor.

  • A high performance airplane is defined as an airplane having MORE than 200 horsepower

Other airplanes you need endorsements same as above for are:

  • Tailwheel
  • Pressurized / High Altitude

You must have a type rating (specific training and a checkride in the airplane) for any airplane:

  • over 12,500lbs takeoff weight
  • Turbojet powered
  • Other aircraft specified by the FAA through aircraft type certification procedures

Pilot Logbooks

You must log what you need to be legally current and legal to act as PIC in the airplane you are flying.  You do not have to legally log every flight you do.

Flight Review

You must have a flight review completed within the past 24 calendar months to act as PIC.  Getting an additional Certificate or Rating counts as a flight review (i.e. getting your instrument rating and passing the checkride resets the 24 calendar month clock).

A Flight Review consists of a minimum of 1 hour ground instruction and 1 hour flight instruction by an authorized instructor

Recent Experience

To carry passengers you need to have made three takeoffs and landings in the past 90 days

If you are carrying passengers more then 59 minutes after sunset or more than 59 minutes prior to sunrise (AKA, at night) you need to have made three full stop takeoffs and landings in the past 90 days.

Your full stop night landings count as currency for daytime flying with passengers.

If you are flying with passengers in a tailwheel airplane, you must make the three required takeoffs and landings to a full stop regardless of whether it is day or night.

The landings must be made in the aircraft of the same CATEGORY and CLASS, and if a TYPE RATING is required, the same type as the one in which passengers will be carried.

Nighttime landings only count when they are done more than 1 hour after sunset or more than 1 hour before sunrise.

Change of Address

You must notify the FAA Airmen Certification Branch of any changes in your mailing address.  You can do so by going to www.FAA.gov

You have 30 days to notify the FAA you moved, after that, you cannot exercise your airmen privileges (it’s easy to go online and fill out the form on the FAA.gov website).

Glider Towing

Any pilot may tow a glider if:

  • You have at least a private pilot certificate
  • 100 hours of PIC time in the aircraft of the same CATEGORY and CLASS, and if a TYPE RATING is required, the same type as the one you will be towing with.
  • A logbook endorsement from an authorized instructor certifying that you have received ground and flight training in gliders
  • Within the past 24 months made at least 3 actual or simulated glider tows while accompanied by a qualified pilot OR made at least 3 flights as PIC of a glider towed by an aircraft

Private Pilot Privileges and Limitations Acting as PIC

You may not pay less than the “pro rata” share of costs when sharing costs flying (you CANNOT make money as a private pilot) I.E. You any your buddy fly somewhere and it costs $150 to rent the plane.  You must pay at least $75.01 of the rental, if you pay less and your buddy pays more than $74.99, you are not complying with the regulations.  Expenses for flying can only involve things like:

  • fuel
  • oil
  • airport fees
  • rental fees

You can only fly an aircraft with passengers on business if the flight is incidental to that business. I.E.  A real estate agent flies a client to go look at a home somewhere and does not charge them for the flight.

You can act as PIC of an airplane carrying passengers for hire when sponsored by a charitable organization and the passengers have paid for the flight via donations to the charitable organization AND:

  • The local FSDO is notified at least 7 days before the flight
  • The flight is conducted from an adequate public airport
  • The pilot has logged at least 500 hours
  • No aerobatic of formation flights are performed
  • The aircraft holds a standard airworthiness certificate and is airworthy
  • The flight is day VFR
  • The flight is non-stop, begins and ends at the same airport, and is conducted within a 25nm radius of the airport.

Part 71

Federal Airways

Federal Airways are class E airspace from 1,200′ agl to 17,999′ msl and are 4nm wide on each side of centerline (8nm wide total)

Part 91

Right of Way

Aircraft in distress have the right of way over all other aircraft

When two airplanes are approaching head-on, both pilots should turn right to avoid a collision

When two aircraft of different categories are approaching each other, the less maneuverable has the right of way. I.E. glider has right of way over a powered airplane

Just like driving, when approaching another aircraft at the same altitude, the aircraft to the right has the right of way

When two aircraft are approaching for landing, the aircraft that is lower has the right of way (except this is not to be taken advantage of, i.e. diving lower to make you be that aircraft with the “right of way”)

When an aircraft (seaplane) and a vessel are on crossing courses the aircraft or vessel to the other’s right has the right of way.

An aircraft towing or refueling another aircraft has the right of way over all engine driven aircraft

Speed Limits

  • 250 knots IAS below 10,000’msl
  • 250 knots IAS in Class B airspace
  • 200 knots IAS underneath Class B airspace
  • 200 knots IAS when within 4nm of the primary airport and lower than 2,500′ agl in class C or D airspace.

Minimum Altitudes

Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:

(a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.

(b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.

(c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

Altimeter Settings

You must set your altimeter to 29.92″ when operating at 18,000′ msl or above (in class A airspace)

Prior to takeoff you should set the altimeter to the local altimeter setting, if no altimeter setting is available, use the field elevation.

ATC Clearances and Instructions

When you obtain an ATC clearance, you may not deviate from that clearance without permission from ATC unless you have an emergency

If you receive priority from ATC during an emergency, you must, UPON REQUEST, file a report with the manager of that ATC facility within 48 hours.

During an emergency you may deviate from any rule necessary to maintain safety.  You should notify ATC of the deviation as soon as possible.

Aircraft Certifications

You must have your Airworthiness and Registration Certificate on board and visible to passengers (really only the Airworthiness has to technically be visible to passengers and crew).

ELTs (Emergency Locator Transmitter)

ELT Batteries must be replaced or recharged after either 1 hour of continuous use or after 50% of their useful life expires

ELTs may only be tested on the ground during the first 5 mins after the hour, no airborne tests are allowed.

Aircraft Lights

Airplanes operating on the ground or in the air between sunset and sunrise must use their lighted position lights (navigation lights, red, green, white).  (does not apply to Alaska)

ATC Transponders

Must be equipped and operating:

  • Above 10,000′ msl (unless within 2,500′ of the surface)
  • In Class A airspace
  • In the Class B Mode C ring and Class B airspace
  • Within and above Class C airspace
  • International Airspace

Aerobatic Maneuvers

Defined as:

  • Nose up or down of more than 30 degrees pitch
  • Bank of more than 60 degrees
  • an intentional maneuver involving an abrupt change in an aircraft’s attitude, an abnormal attitude, or abnormal acceleration, not necessary for normal flight.

Each occupant must have an approved parachute, certified and repacked by an approved parachute rigger within the past 180 days (for parachutes made of synthetic fibers).  (60 days if the parachute is made of silk or other natural fibers).

No person may operate an aircraft in aerobatic flight—

(a) Over any congested area of a city, town, or settlement;

(b) Over an open air assembly of persons;

(c) Within the lateral boundaries of the surface areas of Class B, Class C, Class D, or Class E airspace designated for an airport;

(d) Within 4 nautical miles of the center line of any Federal airway;

(e) Below an altitude of 1,500 feet above the surface; or

(f) When flight visibility is less than 3 statute miles.

Maintenance Responsibility

The owner / operator is responsible for ensuring ADs are complied with.

The owner / operator shall ensure maintenance personnel make the appropriate entries in the aircraft maintenance logs, indicating the aircraft has been approved for return to service.

When alterations or repairs are made to an aircraft that change the flight characteristics of the aircraft, it must be test flown and approved for return to service prior to carrying passengers.  It has to be test flown by at least a private pilot rated for the type of aircraft being test flown.

Required Inspections

  • 100hr inspection if used for hire or flight instruction rental
  • Annual inspection (12 calendar months)
  • 24 calendar month Transponder inspection
  • ELT as discussed above
  • ADs being checked at annual

If the airplane is “out of annual” it was not done before it expired, it is not a problem. The aircraft can be flown again once it has an annual inspection and is returned to service by an IA mechanic (the airworthiness certificate is not valid when the airplane is out of annual, but is valid again once the airplane gets an annual inspection).

You must determine the airworthiness of an aircraft by doing a preflight inspection and checking the maintenance logs.

Accident Notification

NTSB part 830 requires notification of any aircraft accident that causes substantial damage to the aircraft to be reported to the nearest NTSB field office. (you have 10 days to file the paper report)

The following incidents must also be reported to the NTSB:

  • Inability of a required flight crew member to perform their duties due to illness or injury
  • In-flight fire
  • Flight control system malfunction or failure
  • An overdue airplane that is believed to be involved in an accident (report must be filed within 7 days)
  • An airplane collision in flight
  • Jet engine failures (interestingly enough they do not want you to report engine failures on your Cessna 172 or Piper Cherokee)

Report of an incident that required immediate notification only has to be filled when requested by the board.

Preflight Inspection on Cessna Skyhawk 172SP

Preflight Inspection on Cessna Skyhawk 172SP 



Cabin Inspection
1. Ensure that all required paperwork is available.
There are four items of paperwork that should be on board prior to flight.

Remember the letters AROW and you will have no problem recalling what is required:

Airworthiness certificate
Registration certificate
Operating handbook
Weight and balance data.

All these documents need to be on board and the airworthiness certificate needs to be on display in a place where it is visible to passengers.

As a student pilot, you should carry your logbook and student pilot certificate/medical on each flight. However, you can start training with a CFI before you have obtained these.

2. Remove the control wheel lock.

3. Check to be sure the ignition switch is off and keys are not in the ignition.

4. Switch on master switch.

5. Check fuel quantity, but be aware that the gauges are only completely accurate when reading empty. Hence you must also visually inspect the tanks and will calculate your fuel needs.

6. Lower flaps.

7. Master switch off.

8. Fuel valve on.

Exterior Inspection

During the exterior part of the preflight inspection, look for anything that appears to be mechanically unsound. Items such as loose or missing rivets or fasteners, wrinkled surfaces, or anything that just does not look right should be suspect. If in doubt, do not fly!

1. Inspect the empennage.

2. Remove tail tie-down.

3. Check for free movement and security of elevator and rudder. Ensure balance weights are secure.

4. Check antennae.

5. Inspect right flap. Check sliders and security of flap. There should be only slight movement possible.

6. Inspect the right aileron by checking the hinges and ensuring that there is freedom of movement and that the control wheel moves in the correct direction when the aileron is moved.

7. Inspect the leading edge of the wing.

8. Remove wing tie-down.

9. Check right main wheel. The tire should be in good condition and adequately inflated. There should be no signs of brake fluid leaks.

10. Drain a small quantity of fuel from the right fuel tank drain valve and check for water, sediment and proper fuel grade.

11. Inspect upper surface of wing.

12. Visually check fuel quantity by removing fuel cap and looking in the tank.

13. Secure fuel cap.

14. Check oil level.

15. Pull out the fuel-stainer drain knob and collect a sample of fuel to check for and remove any sediment and/or water.

6. Look inside cowling for small animals, lost wrenches, oil leaks, etc.

17. Inspect the nose wheel and fairing. The nose wheel strut and tire should be properly inflated. There should be about two inches of nose wheel strut exposed and no significant leakage of oil from the strut. Check the shimmy damper and the nuts and bolts for security.

While inspecting the nose of the airplane, remain clear of the arc of rotation of the propeller at all times.

18. Check propeller and spinner for damage such as nicks or cracks and security.

25. Inspect the pitot tube.

26. Inspect the leading edge of the left wing. Check stall-warning device and fuel vent.

27. Remove wing tie-down.

28. Inspect the left aileron by checking the hinges and ensuring that there is freedom of movement and that the control wheel moves in the correct direction when the aileron is moved.

29. Inspect left flap. Check sliders and security of flap. There should be only slight movement possible.

30. Check left main wheel. The tire should be in good condition and adequately inflated. There should be no signs of brake fluid leaks.

31. Drain a small quantity of fuel from the left fuel tank drain valve and check for water, sediment and proper fuel grade.

32. Now stand in front of the airplane and take a minute to consider if you have overlooked anything embarrassing, like the tail tie-down, or hazardous, like fuel caps not secured. If everything looks good, your airplane is ready to fly.

Aileron
The ailerons are hinged control surfaces along the trailing outboard edges of each wing used to operate the "rolling" movement of the aircraft. They are the primary control used for turning the aircraft, and they move opposite to each other. To turn right, the pilot turns the yoke or joy stick to the right. The aileron on the left moves down (increasing lift on that side) and the aileron on the right moves up (decreasing lift on that side). As a result of differential lift, the aircraft rotates (rolls) about the fuselage (longitudinal) axis. When a bank angle of about 5 or 10 degrees is achieved, the pilot neutralizes the controls to hold the bank at that angle. With the aircraft banked to the right, it is pulled around the corner by the wing's lift, who's lift vector is also tilted to the right. To complete the turn, the pilot turns the yoke or stick to the left, causing the aircraft to roll in that direction. Once the wings are level again, the pilot neutralizes the controls and straight flight continues.


Elevator
The elevator is the horizontal hinged control surface at the back of the tail used to operate the "pitching" movement of the aircraft. When the pilot pushes forward on the yoke or stick, the elevator deflects downward increasing lift on the tail. As a results, the tail flies up, levering the airplane into a nose-down attitude for descent. Pulling on the yoke or stick results in a climb.


Flap
The flaps are hinged control surfaces along the trailing inboard edges of each wing. They are used to increase a wing's lift by operating together in a downward direction. In a "real" aircraft, a separate control is used to operate the flaps for take-off and landing, otherwise the flaps remain stowed.

In control line model aircraft, flaps are often fitted the entire length of the wings. They control is tied to the elevator, but flaps operate opposite to the elevator. When the elevator moves down (increasing the lift on the tail), the flaps move up (decreasing the lift on the wing). Using flaps in this way creates a more pronounced "pivot" when pitching the aircraft into a climb or descent, which is very handy for aerobatic maneuvers.

Fuselage
This is the longitudinal structure that holds the plane together. In large pressurized aircraft, this is a tube-like structure who's cross-section is almost a perfect circle. This is where the passengers and cargo sit.

In control line model aircraft, the fuselage may be "built up" to resemble a real aircraft, or it may be a more two dimensional "profile" that only resembles a real aircraft when viewed from the side. The advantage of profile models is that they are more aerodynamic and easier to build. The built up models look nicer.

Horizontal Stabilizer
The horizontal stabilizer is the "fixed" horizontal portion of the tail. It is used to move the aircraft's "center of pressure" about its lateral axis aft resulting in stable "pitch" behavior. In large airliners, the horizontal stabilizer is not actually "fixed"; it is hinged so that pitch attitude can be "trimmed" by small adjustments.

In control line model aircraft, the horizontal stabilizer is fixed. Some models have a larger elevator and no horizontal stabilizer.

Landing Gear
The landing gear is the aircraft's wheels, skis, or floats and supporting structures used for takeoff and landing. Large aircraft are almost always fitted with stowable (retractable) landing gear. Stowing the gear greatly improves aerodynamic performance and gas mileage.

In control line model aircraft, landing gear is not usually retractable, except on "scale" models where retractable gear is common.

Propeller
The propeller is shaped like the blades of a fan. It is fitted to the front of the engine. When it turns, it produces the thrust necessary to move the aircraft forward. In "real" aircraft, the propeller is often a "constant speed" arrangement, where the pitch of the propeller changes automatically to keep the engine running at the most effective RPM.

In control line model aircraft, the propeller almost always turns clockwise (right, when viewed from the pilot seat). Less common is the "pusher" prop which turns in the opposite direction. The propeller has fixed pitch.

Rudder
The rudder is the vertical hinged control surface at the back of the tail used to operate the "yawing" movement of the aircraft. It is operated by the pilots foot pedals. Pressing the right foot pedal deflects the rudder to the right causing the aircraft to rotate about it's vertical axis. This control alone would result in an "uncoordinated" (skidding) right turn. This kind of turn is very uncomfortable for pilot and passengers as sideways forces are felt throughout the turn. Under normal circumstances, rudder is used sparingly and in cooperation with the ailerons to achieve a "coordinated" turn, where the tail follows the path of the wings rather than skidding and slipping about behind them.

The rudder has limited application to control line model planes because the models are constrained to fly in the semi-sphere around the pilot by the control lines. Since control lines come out of the model's left wing tip, the rudder is often permanently deflected to the right to keep the lines tight. Some models are equipped with a ground-adjustable rudder which can be deflected to suit the weather conditions of the flight.

Spinner
The spinner acts as a fairing and protection for the parts that hold the propeller to the engine. It also conceals the "constant speed" mechanism of the propeller.

In control line model aircraft, the spinner may or may not be fitted. Often the spinner replaces the nut holding the propeller to the engine.
Vertical Fin
The vertical fin (or vertical stabilizer) is the "fixed" vertical portion of the tail. It is used to move the aircraft's "centre of pressure" about its vertical axis aft resulting in stable "yaw" behaviour.

In control line model aircraft, the vertical fin has the same purpose. It may be aligned down the aircraft's longitudinal axis, or it may be deflected to the right with the rudder to help keep the control lines tight. It is often the first part of the model to break off when the aircraft noses over in a hard landing.

Wing
The wing is the device that holds the airplane aloft be creating lift. It does this by making the path over the wing longer than the path under the wing. As air molecules pass by the wing, greater air pressure exists along the shorter path under the wing. This differential air pressure pushes the airplane up.

In control line model aircraft, the profile of the wing is often symmetrical. To change the length of the path "over" or "under" the wing, the wing is tilted into an "angle of attack" that achieves the desired lift. The advantage of the symmetrical profile is that the aircraft behaves the same in inverted flight as in regular flight
