7.16.7.1. Compound wind problems.

1. On a low-level flight two minutes prior to your next turn point, your inbound course is

210 and temperature is 27. You calculated the wind to be from your 10 clock and 20 knots.

The outbound course is 270. The proper heading and airspeed for the two minute prior call is

and

Knots.

2. On a low-level route you fly over a highway bridge at time 14 + 32. Preflight planning

indicated the bridge would be at 9 o'clock, 1 NM at time 14 + 18. If TAS is 300 knots and

aircraft heading is 336, you should initiate your correction by turning to a heading of

knots.

and setting a speed of

3. Low-level route wind analysis indicates winds to be from 8 o'clock at 15 kts

(compensations were 2 left crab and base airspeed minus 5 kts tailwind). At your last

intermediate check point you were on course and 4 seconds fast. At your next intermediate

checkpoint you fix yourself 1/2 NM left of course and 9 seconds fast. Assuming 5 minutes

between intermediate checkpoints. What is the new wind in clock code and knots?

4. On a low-level route you fix your position 1-NM left of a fire tower at time 15 + 12.

You've preflighted the tower to be 1 NM left course at time 15 + 06. Your last turn point at time

11 + 18, you were on course and on time. Your base course is 175 and base. Airspeed is 295

KIAS. What are your compensations and correction?

5. You mark yourself NM left abeam a turn point 6 seconds fast. After turning right 90

where are you in terms of course and time?

6. Low-level route wind analysis indicates winds to be from 2 o'clock at 20 kts

(compensations were 3 right crab base airspeed plus 10 kts headwind). At the last fix, the

aircraft was 1/2 NM right of course and 2 seconds slow. At the next intermediate checkpoint, the

aircraft is 1 NM left of course 6 seconds fast. Assuming 7 minutes between intermediate

checkpoints, what is the new wind in clock-code and knots?

7. On a low-level flight, two minutes prior to your next turn point your inbound course is

035 and temperature is 27. You calculated the wind to be from your 1 o'clock and 15 knots.

Outbound course is 275. The proper heading and airspeed for the two minute prior call is

and

knots.

8. On a low-level route you fly over a microwave tower at time 7 + 48. Preflight planning

indicated the tower should be at 3 o'clock, 1 NM at time 7 + 30. If TAS is 290 knots and

compensated heading is 243 you should initiate the correction by turning to a heading of

and setting a speed of

Knots.

9. Current compensations are 1 left crab and airspeed plus 10 kts headwind. At your last

intermediate checkpoint you were on course and 6 seconds slow. At your next intermediate

check point you fix yourself 1 NM left of course and 11 seconds slow. With 4 minutes between

intermediate checkpoints, what is the new wind in clock code and knots?
