## SAMPLE SOLUTION:

54° compass course

+5° east deviation

59° magnetic course

Ð11° west deviation

48° true course

1. A pilot is steering a course of 1750. If the variation is 12’ west and deviation is 3’ east, what is the true course?

- 2. A plane is steered along a compass course of 180. If the variation is 110’ west and deviation is 3’ east, what is the true course?
- 3. Evaluate the distance formula for the values given.

D = RT DISTANCE = RATE OF SPEED X NUMBER OF HOURS

A. dr = km/hr B. r = 60.16 C. r = 90 km/min t = 5.5h t = 6.10 t = 6.16 min d = ___ km d = ___ km d = ___ m - 4. The true course from airport Z to airport Y is 104. If the variation is 6’ west and the deviation is 3’ east what compass course should be steered?

5. During a certain flight, the flight navigator found that the compass course was 268. If variation is 8° east and the deviation is 6° what is the true course? - 6. What compass course should a pilot steer if the true course is 63°, variation 9’ east, and deviation is 7° west?
- 7. Compute the compass course if the true course if 128°, variation 8° east, and deviation 4° east?
- 8. What compass should be steered if the true course is 235°, variation 12° west, and deviation 4° east?
- 9. A pilot is determining the compass course, uses the following data: true course 350°, variation 13° west, deviation 3° west. What is the compass course?
- 10. Find the magnetic course:

True Course Variation A. 4°° 5° west B. 164° 19° east - Find the compass course:

Magnetic Course Deviation C. 157° 1° east D. 65° 2°west
