When should the rudder boost system be turned off?

The rudder boost system should be turned off during the climb checklist. This is an essential step in the aircraft's operational procedures as the climb is a critical phase of flight where pilots ensure that all systems are functioning correctly and safely. Turning off the rudder boost after takeoff, but before entering the climb, helps maintain proper aircraft handling characteristics as the aircraft climbs to its cruising altitude.

The rudder boost is generally used to assist the pilot in countering asymmetric thrust conditions, especially during takeoff when one engine may be producing more thrust than the other. Once in a stable climb, the need for rudder assistance diminishes, and turning it off can enhance the pilot’s control over the aircraft, allowing for a more natural response from the controls.

This practice promotes safety by ensuring the aircraft operates within its designed parameters and encourages pilots to manage their systems appropriately as they transition through different phases of flight.
