Aviation Standard Test Battery-E (ASTB E) Practice Test

What does the term "Coriolis Force" refer to in aviation physics?

1. The effect of gravity on flight paths

2. The change in rotational speed due to weight shifts

3. The influence of wind on aircraft control

4. The resistance encountered during ascent and descent

The correct answer is: The change in rotational speed due to weight shifts

The term "Coriolis Force" in aviation physics refers to an apparent force that arises from the rotation of the Earth, affecting the motion of objects moving over its surface. It is not directly related to mere gravity effects, wind influences, or resistance encountered during ascent and descent. Instead, it describes how the rotational motion of the Earth can cause a projectile (including aircraft) to veer away from its original path, resulting in a perceived deflection. In the context of option B, the Coriolis Force manifests in various scenarios, particularly in celestial navigation and when accounting for the movements of air masses in weather patterns. When weight shifts occur, like during turns or changes in flight configuration, pilots must be aware of how these shifts influence the aircraft's trajectory due to the Coriolis effect. This understanding is essential for maintaining accurate control and navigation.
