An improvement in an aircraft of the type having a passenger cabin, a wing with a wall defining a leading edge and having a vent/air intake opening therein and a conduit communicating between the vent/air intake opening and the cabin to provide ventilating air from externally of the aircraft to the cabin. The improvement is an air flow blockage plate that is removably fixed to the wing wall so that in its operative position the air flow blockage plate intercepts and deflects the flow of onrushing air directed towards the vent/air intake opening away from the vent/air intake opening as an incident of the aircraft moving forwardly relative to an air mass.
