Cover for aircraft apertures

摘要

A protective cover (2) for apertures in aircraft comprises a cover portion (6) surrounded by a fixing portion (5). A warning flag portion (7) extends radially outwardly from the fixing portion (5). The fixing portion (5) is provided with an adhesive layer by which the cover is attached to the skin of an aircraft. The cover portion (6) is preferably transparent to assist aligning of the cover with the apertures to be covered. The cover (6) may be flat or may be profiled to receive a structure projecting from the skin of the aircraft. Such structures include pitot tubes (Figs 5, 6) and stall warning vanes.
