How long should it take to advance the throttles to TRT during rolling takeoffs?

Advancing the throttles to thrust rating takeoff (TRT) during rolling takeoffs should typically be done within a timeframe of 1-3 seconds. This duration allows for a smooth and controlled increase in thrust that helps ensure the aircraft maintains stability and responds correctly during the critical phase of takeoff. Quick throttle advancement helps the aircraft reach the required power without causing excessive drag or noise that could affect performance or the surrounding environment.

The 1-3 second timeframe also aligns with standard operating procedures intended to improve engine response and maintain safety margins during takeoff. By adhering to this timing, pilots can effectively manage the aircraft’s acceleration while still being ready to respond to any immediate needs during the takeoff roll. Proper timing in throttle application plays a critical role in achieving optimal performance during this essential flight phase.
