ABSTRACT:
Aircraft ventilating visor systems have small tubes insertable in openings into fresh air wing conduits at the interfaces of wings and cabins near the upper portions of windshields in high wing aircraft. Existing pull-open, push-closed turnable air directors are removed and replaced with hollow tubes which supply air to hollow visors. Thin louver-controlled openings along lower edges of the visors control and direct air supplied to front seat occupants.
Larger central openings in the rear faces, when the visors are in the down position, are controlled by directional louvers to supply air axially through the aircraft between the front seats to passengers in rear seats. An outside air temperature gauge in mounted axially in one of the connecting tubes. The hollow visors are made of clear see-through, tough, plastic material, and have guides into which removable amber glare-reducing plates are fitted.
