What Happens During Landing: Every Sound, Decoded
Landings feel busier than takeoffs because more systems deploy in the final 10 minutes. For nervous flyers, the increase in sounds can feel alarming. Here's the timeline of a typical descent and landing — every sound, decoded.
T-30 minutes: top of descent
The pilots reduce engines to idle. The aircraft begins descending at a shallow angle (about 3°). You'll notice cabin air noise increase — the aircraft is trading altitude for speed. Your ears may pop as cabin pressure adjusts; chewing gum or yawning helps.
T-15 minutes: speed reduction
The aircraft begins slowing. You may hear engines briefly increase, then return to idle. Slight buffeting is normal as the aircraft transitions from cruise speed to approach speed.
T-10 minutes: first flap deployment
Pilots extend flaps in stages — usually 1, 2, then 3. You'll hear motors whirring and feel small bumps as the wing reconfigures. The aircraft slows further. This is normal and expected.
T-5 minutes: turn to final approach
The aircraft completes its turn onto final approach — pointing at the runway. You may feel banks and pitch changes as the pilots align with the runway.
T-3 minutes: landing gear extension
A loud clunk and increased airflow noise — the landing gear is now down and locked. Some aircraft (especially the 737) have particularly loud gear deployment. The cabin gets noisier from the additional drag.
T-1 minute: full flaps
Final flap setting — full extension. The aircraft is now in 'landing configuration' — slow, draggy, fully ready to touch down. Engine noise increases somewhat as the pilots add thrust to maintain glide angle.
T-30 seconds: short final
The aircraft is steady on glide path, about 200 feet above the ground. You may hear engines spool up and down as pilots make small power adjustments. This is normal correction, not problem.
T+0: touchdown
The main wheels contact the runway first — you feel a firm bump. Pilots prefer firm landings over soft ones because they let the brakes engage immediately. A bouncy landing is fine. A solid 'thud' is good.
T+1-5 seconds: deceleration
Several things happen at once: spoilers deploy on top of the wings (you'll see them rise if you have a window seat), reverse thrust engages (a loud roar from the engines), and wheel brakes apply. This is the strongest deceleration of the entire flight.
T+10-30 seconds: rollout
The aircraft slows from landing speed (about 130 knots) to taxi speed (about 20 knots). The reverse thrust roar fades. The aircraft turns off the runway onto a taxiway.
T+5-15 minutes: taxi to gate
The aircraft taxis at walking pace. You'll hear small bumps from runway joints, the occasional thump as the aircraft turns, and engines spooling up and down. Stay seated until the aircraft reaches the gate and the seatbelt sign is off.
