ABSTRACT:
An unfurlable sheet is normally stored within a hollowed fillet existing between the fuselage of an aircraft and a confronting edge of the aircraft wing. When the surface area of the wing is to be increased, the sheet is unfurled so that it becomes coplanar with the edge of the wing and the confronting surface of the fuselage. By unfurling the sheet during a "deep stall" condition, the downward vertical velocity of the aircraft may be appreciably diminished.
