T-30s — engines spool up
You'll hear the engines climb in pitch as the pilots set takeoff thrust. The brakes are still holding the aircraft. Completely normal.
T+0 — brake release, takeoff roll
You'll feel pressed back into your seat. Acceleration is firm but smooth — about 0.3g, similar to a sports car. Crew watches airspeed and engine instruments continuously.
T+25s — V1, rotation, liftoff
At V1 the takeoff is committed. A few seconds later the pilot pulls back gently, the nose lifts, and the wheels leave the ground. The pitch-up feels steeper than it is — actual climb angle is around 12-15°.
T+30s — gear retraction (the thunk)
A solid clunk under the floor as the landing gear folds into the fuselage. This is expected and happens on every flight.
T+60-180s — power reduction
Engines step back from takeoff thrust to climb thrust. The cabin gets quieter — this can feel like the engines have stopped. They haven't; they're at ~85% of takeoff power.
T+3-10min — flap retraction
You may feel a slight slowing or settling sensation as the flaps retract. The aircraft is now in clean configuration and accelerates to climb speed.
