What does a higher number on the AOA gauge scale indicate?

• A. Lower lift conditions
• B. Greater angle of attack
• C. Decreased speed
• D. Improved aerodynamic efficiency

Answer: (B)

A higher number on the angle of attack (AOA) gauge scale indicates a greater angle of attack. The angle of attack refers to the angle between the chord line of the wing and the oncoming airflow. When this angle increases, it typically means that the aircraft is increasing its lift potential up to a certain limit. A greater angle of attack is essential during specific flight scenarios, such as slow flight or takeoff, where pilots aim to generate maximum lift. However, exceeding the critical angle of attack can lead to a stall, which is why pilots closely monitor the AOA gauge. In contrast, the other options do not accurately describe the implications of a higher AOA reading. While it is true that higher angles can be associated with slower speeds during certain maneuvers, the primary interpretation of an increased number on the AOA gauge is that the angle of attack itself is greater. This is crucial for understanding flight mechanics and effective aircraft operation.
