Anyone who regularly flies on commercial aircraft has likely noticed the same curious sensation shortly after take-off. The engines roar at full intensity during the take-off roll, the aircraft rotates, and within moments of becoming airborne, the sound suddenly softens as the thrust appears to decrease. For nervous passengers, that brief reduction in power can feel unsettling, especially because it happens at a stage of flight when the aircraft is still climbing away from the runway and remains relatively close to the ground. So in this video, we take a look at why pilots deliberately pull back thrust shortly after lifting off the runway, how modern aircraft rarely need maximum power in the first place, and why this procedure actually improves efficiency, reduces engine wear, and helps keep flights safe.
