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

How is flight attitude defined in aviation?

1. The aerodynamic efficiency of the wings

2. The speed of the aircraft in flight

3. The position of the plane in motion relative to three axes

4. The altitude of the aircraft above sea level

The correct answer is: The position of the plane in motion relative to three axes

Flight attitude is defined as the position of the aircraft in motion relative to its three axes: pitch, roll, and yaw. In aviation, these axes are essential for understanding how the aircraft is oriented in space during flight. The pitch axis runs horizontally from wingtip to wingtip and controls the nose up or down attitude; the roll axis runs from nose to tail and affects the banking of the aircraft; the yaw axis runs vertically through the center of the aircraft and determines the left or right rotation around the vertical axis. Understanding flight attitude is crucial for pilot navigation and control of the aircraft, as it directly influences maneuvers, stability, and overall performance. The other options do touch on various aspects of flight but do not accurately describe the concept of flight attitude. For instance, aerodynamic efficiency relates to wing design, speed pertains to the aircraft's velocity, and altitude focuses on vertical distance from sea level, none of which capture the essence of how the aircraft is positioned in relation to its axes in flight.
