The invention relates to a pressurized aircraft door that minimizes risk of ingress of precipitation inside the aircraft, while maintaining venting of the aircraft before unlocking the door. The purpose of the invention is achieved using a vent flap controlled by a door control member and designed such that the flap successively occupies the following positions during the opening movement of the control member: a closed position when the control member occupies a first end position putting the door in a closed/locked position; at least one partially open position before the door is in a closed/unlocked position; then once again in the closed position when the control member occupies a second end position putting the door in an open position.
