Angle of Attack is an important aeronautical concept used to understand the aerodynamic performance of an aircraft during different flight stages. The Federal Aviation Administration has indicated the importance of developing and encouraging the use of AOA based systems to increase flight safety. This study examined the usability of three different AOA indicators. The goal was to identify which of these indicators is better suited for student pilot training. Instructor pilots were recruited for a series of flights, in which they were asked to perform different maneuvers while using AOA indicators. The data show significant differences between the indicators with a general preference for a vertical representation of AOA.
