FAA Ground School Practice Test

What is the wind direction and speed reported by a pilot at 12000 ft MSL?

1. 080 degrees at 21 knots

2. 180 degrees at 10 knots

3. 360 degrees at 15 knots

4. 270 degrees at 5 knots

The correct answer is: 080 degrees at 21 knots

The wind direction and speed reported by a pilot at 12,000 feet MSL corresponds to a specific measurement that reflects the wind's direction in degrees from true north, as well as its speed in knots. In the context of aviation, wind is typically reported using meteorological formats where the direction is expressed in degrees, and a fully developed report includes both components. Choosing the measurement of 080 degrees at 21 knots indicates that the wind is coming from the east-southeast (80 degrees being slightly south of directly east) and has a speed of 21 knots, which suggests a moderate wind that could impact flight operations, especially during takeoff and landing phases. This level of detail in wind reporting is essential for pilots, as it helps them make necessary adjustments for navigation and flight control, in addition to informing them about the potential for turbulence or changing flight conditions at that altitude. The choice reflects an accurate representation of how wind data is recorded and the importance of direction and speed in aviation contexts.
