Abstract
The general field of the invention is that of the management of the faults of the viewing devices used on aircraft. An aircraft instrument panel viewing device comprises an electronic assembly, embedded software and a viewing screen. When the viewing device detects a fault arising after a predetermined time of proper operation, the reinitialization method according to the invention executes just the software verification tests without executing the electronic assembly verification tests termed “safety tests”, no specific presentation of fault being displayed on the viewing screen. The duration for which the pilot is deprived of information is thus considerably reduced.
