What do control column shaking and an angle-of-attack display on cockpit indicators warn you of?

• A. Engine failure
• B. Impending stalls
• C. Hydraulic leak
• D. Overspeed

Answer: (B)

These indicators are signaling an approaching stall. The control column shaking acts as a stick shaker, a tactile warning from the flight control system that the angle of attack is near the critical point where lift starts to collapse. The angle-of-attack display provides a direct readout of how high your wing’s angle is relative to the oncoming airflow, so you can see you’re close to or at the stall margin. When the wing is at high angle of attack, airflow separates from the upper surface, lift drops, and the stall can develop if you don’t respond. The combined cues remind you to reduce the angle of attack or increase airspeed to regain safe lift. This isn’t about engine, hydraulics, or speed limits being exceeded in the same way; those other faults have different indicators. In practice, you’d lower the nose to decrease the angle of attack and, if needed, add power to restore safe flight.
