All pressurized aircraft (all built in the 90s I believe) that I have flown have dump valves actuated by the gear squat switches, meaning without a system fault the aircraft cannot be pressurized on the ground. Proper pressurization control starts pressurization in the initial climb, and returns ΔP to 0 on short final. Other aircraft likely differ. | |

Now, I heard that before takeoff, the pressure is already increased a little for higher stability of the fuselage. May be, this is wrong, but I had another experience: You are correct . Before rotation or in simple language just before take off, modern aircraft are pre-pressurised. This is to avoid surge in the cabin pressure.
