FAA Ground School Practice Test

What is the predicted wind condition for KMEM from 1600Z until the end of the forecast?

1. Northwest at 8 knots

2. Variable in direction at 6 knots

3. Southwest at 12 knots

4. East at 15 knots

The correct answer is: Variable in direction at 6 knots

The predicted wind condition for KMEM from 1600Z until the end of the forecast reflects the meteorological practice of noting variable winds. When winds are described as "variable in direction," it means that the wind is not blowing consistently from one specific direction but instead is shifting between different directions within a certain range. This scenario is particularly common in areas where weather patterns are unstable, or there are many local influences affecting wind direction. In aviation, knowing that winds are variable in direction can be crucial for flight operations, as it affects flight planning, takeoff, and landing procedures. The speed of 6 knots accompanying this statement indicates a light wind condition, which generally means minimal impact on aircraft performance. Understanding that other options provided fixed wind directions highlights the difference between steady, predictable winds and variable winds. The presence of a consistent direction can indicate more stable weather conditions, while variability usually suggests a less predictable environment. Therefore, the wind condition described aligns well with meteorological interpretations based on observational data and forecasts.
