STUDENT GUIDE
10. On a low level flight two minutes prior to your next turn point your inbound course is
180° and temperature is 27°. You calculated the wind to be from your 12 o'clock and 20 knots.
The outbound course is 090°. The proper heading and airspeed for the two minute prior call is
° and
Knots.
11. Flying a base airspeed of 300 knots you cross a checkpoint at 12 + 49 preflighted for 12
+ 36. You make the standard speed correction. At time 17 + 49 you realize the correction was
not taken out. Assuming error is due to course deviations for weather, what is your correction to
get back on time?
12. Compensations areright crab and airspeed minus 5 kts tailwind. At your last turn
point you were 1 NM right of course and on time. At your next intermediate checkpoint you fix
yourself ½ NM right of course and 7 seconds slow. Assuming 5 minutes between intermediate
check points, what is the new wind in clock 'code and knots?
13. Two minutes prior to the turn point, inbound course is 076° and temperature is 27°.
Winds are from 7 o'clock and 15 knots. The outbound course is 051°. The proper heading and
° and
Knots.
airspeed for the two minute prior call is
14. The fix over a road intersection is at time 9 + 06. Preflight planning indicated the
intersection would be at your 9 o'clock, ½ NM at time 9 + 21. If TAS is 300 knots and aircraft
° and setting
a speed of
Knots.
15. Compensations areright crab and airspeed minus 15 kts tailwind. At your last
intermediate checkpoint you were on course and on time. At your next intermediate check point
you fix yourself 1 NM right of course and 8 seconds slow. Assuming 7 minutes between
intermediate checkpoints, what is the new wind in clock code and knots?
16. The T-1A aircraft crosses an intersection at time 15+18. The chart shows the
intersection on course with an original time of 15+00. At the previous fix (9+00), the aircraft
was on time. With a current compensated airspeed of 295, what is the new compensated
airspeed, and what is the appropriate correction?
New Air Speed:___________
Accelerate/Slow to ___________ IAS for _____ + ______.
17. (Refer to question 16.) After applying the above correction at 16+00, what is the
updated time for a turn point that was planned for 18+00?
18. (Refer to question 17.) You have just crossed over the turn point referenced in question
17 at time 18+09. When will your correction be taken out?
