fluidly connecting, via the connection means, the venting valve to the pressure tap port of the aircraft from the outer side of the aircraft while the aircraft is on the ground, the shutter being in the open position;
moving the shutter of the venting valve from the open position to the closed position thereof; and
activating the vacuum pump to produce a reduced pressure in an inner volume of the connection means and the venting valve to generate a reduced pressure in a region of the pressure tap port of the aircraft.
