FAA Ground School Practice Test

In a wind triangle, what does the line from point A to point B represent?

1. Groundspeed and true course

2. True heading and airspeed

3. Groundspeed and wind direction

4. True course and wind speed

The correct answer is: True heading and airspeed

In a wind triangle, the line from point A to point B represents the true heading and airspeed of the aircraft. This line indicates the path that the aircraft must fly through the air to maintain its intended course, taking into account the effects of wind. The true heading refers to the compass direction in which the aircraft is pointing relative to true north, while airspeed is the speed of the aircraft relative to the air around it. Therefore, the segment from A to B encapsulates both how the pilot aims the aircraft and how fast it is flying through the air, which is crucial for navigation and flight planning. Understanding this concept is essential for pilots because it helps them account for wind correction angles when navigating and ensures they can maintain their desired course despite the influence of wind.
