What type of protection is indicated to be active when the aircraft is in a specific flight condition?

Alpha floor protection is a safeguard that activates under specific flight conditions, primarily when the aircraft is approaching its stall speed. This system is designed to prevent an inadvertent stall by automatically providing full thrust to the engines, regardless of the thrust lever position.

When the aircraft enters a configuration where the angle of attack becomes excessively high, indicating a potential stall scenario, alpha floor protection ensures the aircraft maintains a safe level of airspeed. This is particularly crucial during flight phases such as takeoff and landing, where the margins for error are lower, and the risks associated with stalling are significantly heightened.

The other options, while they represent valid protective measures under different conditions, do not apply to this scenario. High-speed protection limits the maximum speed to prevent overspeed, bank protection restricts excessive bank angles to maintain safe flight dynamics, and 'no protection' indicates that the aircraft might not be utilizing any form of active protection. These alternatives address various aspects of flight safety but do not focus specifically on preventing stalls like alpha floor protection does.
