Which statement best describes when the pusher engages on the AOA gauge?

• A. At 0.8 AOA (start of red arc)
• B. At 1.0 AOA deep into the red arc
• C. At 1.2 AOA near the end of the red arc
• D. At 0.9 AOA before the red arc

Answer: (B)

The pusher activates as part of stall protection once the aircraft’s angle of attack reaches a calibrated threshold inside the stall warning region. The red arc on the AOA gauge marks the high-risk area for stall. Engaging at about 1.0 AOA puts activation after the first warning but with enough margin to help prevent a full stall, by pushing the nose down to reduce AOA. If it fired at the very start of the red arc, it would be premature; if it waited until near the end of the red arc, there might not be enough time to recover. Therefore, triggering around 1.0 AOA deep into the red arc is the most effective timing.
