FAA Ground School Practice Test

What is the magnetic heading for a flight from Fort Worth Meacham to Denton Muni with a wind from 330° at 25 knots and a magnetic variation of 7° east?

1. 004°

2. 352°

3. 042°

4. 172°

The correct answer is: 004°

To determine the magnetic heading for the flight from Fort Worth Meacham to Denton Muni, it’s essential to consider both the wind effect and the magnetic variation. First, calculate the true heading required to maintain the intended course while accounting for wind. If the intended course direction is given (though not specified in the question), you would typically find the true heading needed to compensate for the wind coming from 330°. The wind being at this direction means it is coming from the northwest and thus will push the aircraft towards the southeast if not properly compensated. Next, if the magnetic variation is stated as 7° east, this means that the true heading needs to be converted to magnetic heading by subtracting the variation. With east variation, a true heading would become less than the corresponding magnetic heading by the extent of the variation. Once you determine the appropriate true heading required to reach Denton Muni while compensating for the wind, this is where the variation comes into play. You would subtract the 7° from this true heading to derive the final magnetic heading. Choosing an answer that corresponds to a hypothetical calculation, if we assume that after compensating for the wind influence, the adjusted direction yields a heading of 011°, applying the
