What is the purpose of a wave-off ball in aviation?

To indicate the correct altitude during landing

To signal the pilot to abort a landing

The purpose of a wave-off ball in aviation is to signal the pilot to abort a landing. In certain situations, such as when conditions are not optimal for landing, a wave-off signal is communicated to ensure that the pilot understands the need to go around and attempt another approach. This signal is crucial for safety, allowing pilots to avoid landing in potentially hazardous situations, such as improper alignment, poor visibility, or runway obstructions.

The other choices pertain to different aspects of flight operations, such as altitude management, speed monitoring, and angle of attack measurement, but they do not relate to the specific function of a wave-off ball.
