Determine the magnetic heading for a flight from Allendale County Airport (area 1) to Claxton-Evans County Airport (area 2). The wind is from 090° at 16 knots, the true airspeed is 90 knots, and the magnetic variation is 6 degrees West.

206°

Explanation:

To find magnetic heading as required by the question. We need to first determine the true heading by correcting true course for winds. Then, correct true heading for magnetic variation.

Step 1. Plotter is used to measure true course = (212°).

Step 2. The flight computer is used to determine true heading by

1. Enter the wind direction and speed (090° at 16 knots).

2. Enter the true course (212°).

3. Enter the TAS (90 knots).

4. True Heading TH = 212°

Convert TH to MH

Since the magnetic variation is 6°W).

Since this is a west variation, you must subtract it from the true heading.) TH± Variation = MH 212° – 6° = 206°.
