Check RIde - Diversion

During Diversion:

• Heading - What is your new heading (Triangulated method East 90 Deg, South 180 deg, west 270
• Altitude  - Odd Thousand + 500, Notify ATC of intentions or ask for vectors)
• Navigate -  Use Aircraft Navigation equipment GPS Direct/VOR to make sure you are navigating to airport
• Distance - Use Plotter - (use Nautical Miles not Statue Miles) How far are you away from airport. When you are flying with no headwind or tail wind your ground speed is the same as true airspeed
• Time - E6B How long it will take us 
• Fuel   - What is your fuel burn  (from POH /Flight plan) (9Gal/hr)
• Weather  - What is the Weather at destination airport
• Notams

Using your E6B and VFR Chart you must answer:  (create a winds card
Calculate at Altitude what the Ground Speed will be in All Direction . All headings - 360, 050, 090, 140, 180, 230, 270, 320

• What heading should I fly?
• How long will it take me?   (Wind Card)
• Will I make it?  Traveling at ABC Ground speed for XYZ miles - do you have enough Fuel?

Create a Wind/Speed CArd with Wind Aloft information 

change your windcard from displaying groundspeed to displaying a headwind or tailwind component for each sector e.g. +5 or -8 because during a diversion in which fuel conservation is a consideration then it's possible you may be required to decrease power (increase range/endurance etc).
