FAA Ground School Practice Test

At KJFK, the wind direction and velocity is reported as what?

1. 360 degrees at 10 knots

2. 180 degrees true at 4 knots

3. 270 degrees at 8 knots

4. 90 degrees at 5 knots

The correct answer is: 180 degrees true at 4 knots

In aviation, wind direction is typically reported in degrees, indicating the direction from which the wind is coming, and is often given in relation to true north. The wind velocity is reported in knots and reflects how fast the wind is blowing. The answer indicates that at KJFK, the wind is coming from 180 degrees true, which means the wind is coming from the south. A velocity of 4 knots means that the wind is blowing at a speed of 4 nautical miles per hour. This is crucial in flight operations because it affects takeoff and landing procedures, as well as in-flight performance. Knowing the wind direction and speed helps pilots make informed decisions regarding flight paths, approaches, and other operational aspects. The reported wind information serves as a critical factor for pilots to align their aircraft appropriately and ensure safety and efficiency. Understanding the influence of wind on an aircraft’s flight characteristics is fundamental for pilots, as it has a direct impact on ground speed, drift, and overall flight dynamics. This wind information also plays a crucial role during pre-flight planning, approaches, and landings, offering essential data for maintaining control and stability in varying conditions.
