What is a key characteristic of ALPHA FLOOR?

The key characteristic of ALPHA FLOOR is that it commands full takeoff/go-around (TO/GA) thrust regardless of the thrust lever position. This function is crucial for ensuring adequate performance and avoiding a stall during critical flight phases, particularly when the aircraft is operating near the stall margin. When the aircraft’s alpha (angle of attack) exceeds a certain threshold, the ALPHA FLOOR protection mode activates automatically, overriding the thrust lever settings to provide maximum thrust.

This feature is important in enhancing safety during situations where an increase in thrust is necessary to maintain control of the aircraft, especially in high angle-of-attack conditions. ALPHA FLOOR serves as a safety mechanism that helps pilots recover from unintentional slow flight situations by automatically delivering the power needed to regain control and maneuverability.

The other options do not correctly describe characteristics associated with ALPHA FLOOR. For instance, while airspeed is a critical factor in the aircraft's performance, well above the conditions of ALPHA FLOOR, the scenario does not hinge specifically on operating below alpha max. Additionally, ALPHA FLOOR is typically not available in alternate law, as this mode of operation is primarily activated within normal law settings. Lastly, ALPHA FLOOR does not remain available until touchdown in the landing configuration, as
