Flight Time Question 8 -56

Flight Time Question

8-56
(Refer to figure 23 on page 4-24)

Determine the estimated time en route for a flight from Priest River Airport (area 1) to Shoshone County Airport (area 3.  The wind is from 030 at 12 knots and the true airspeed is 95 knots. Add 2 minutes for  Climb-out.

a.  27 minutes
b.  29 minutes
c.  31 minutes


                        Priest River                             Shoshone County
From Airport ____________       To Airport ___________

• True Course   =   (draw line from Airport A to Airport B and measure the angle)  142 Deg 
• Distance         =    (measure the distance in knots from airport a and airport b) 48 nm
• Wind Direction/Wind Speed  = 030 @ 12 knots  (given)
• True Airspeed  = 95 knots  (given)
• Ground Speed =  98 knots (calculated)
• Added Time = 2 mins (given)

Distance
------------------   x 60 mins   = Flight Time  in minutes
Ground Speed


With E6B computer .

1. Put the gomet (hold) on the 100 arc
2. Put the value of the True Course (142 deg) under the True Index of the E6B Computer
3. look at wind speed (12 Knots) and mark it above the gomet with a dot
4. Look at the wind direction (30deg) under the true course index you put 30 degrees
5. Notice the dot moves to the right
6. Move the sliding card so that the dot is over 95 (for 95 Knots)
7. Look thru the gomet and see what arc goes thru it  (98 Knots)

Distance  48
------------------         x 60 mins   = Flight Time  in minutes   = 29.4  + 2 mins = 31.4 mins
Ground Speed  98
