During landing, when maintaining reverse thrust, what is essential to avoid below a certain airspeed?

Maintaining max reverse thrust during landing is crucial below a specified airspeed to ensure that the aircraft decelerates effectively and prevents any potential loss of directional control. When the aircraft is at lower speeds, the aerodynamic control effectiveness diminishes, making it difficult to manage and stabilize the aircraft’s trajectory if reverse thrust is not maximized.

By utilizing maximum reverse thrust, pilots can take full advantage of the available thrust to slow down, especially on short runways or in wet conditions where stopping distance is critical. It also minimizes the risk of the aircraft moving forward in an uncontrolled manner due to insufficient braking friction or directional control. Thus, in lower airspeed conditions, max reverse thrust plays an essential role in safe landing practices and helps in managing the aircraft's energy effectively during this critical phase of flight.
