What really happens during takeoff and landing

The speeds that mark takeoff

Takeoff follows three thresholds calculated for each flight based on weight, runway, and weather: V1, the decision speed beyond which the takeoff cannot be safely aborted; Vr, the rotation speed at which the pilot pulls up the nose; V2, the minimum climb speed after wheels-up. From brake release to wheels-off typically takes between 30 and 50 seconds, depending on the aircraft type, takeoff weight, and runway length.

What produces the noises in the first minutes of flight

The metallic click heard just after takeoff almost always corresponds to landing gear retraction: the wheels lift into their compartments and the doors close, a mechanical sequence lasting just a few seconds. The change in engine tone shortly after reflects instead the power reduction from maximum takeoff thrust to climb thrust, set to reduce fuel consumption and noise at ground level.

How landing is calculated

The descent toward the runway follows a glide path with a constant angle, typically around 3 degrees, which pilots maintain by continuously adjusting engine power and aircraft attitude. In the final minutes before touchdown, small adjustments compensate for wind and residual turbulence: sensing non-uniform altitude changes at this stage is normal.

Why noise intensifies right after touchdown

The intense noise heard when wheels touch the ground is thrust reversal: the engines divert part of the airflow forward to slow the aircraft, a standard procedure on almost all commercial flights and not a sign of a hard landing. Those who struggle more with takeoff anxiety than with noise will find practical guidance in this guide.

If a sound during takeoff or landing concerns you, try to place it in one of these phases before worrying: in the vast majority of cases it corresponds to a planned procedure, not an anomaly.
