Method of fast reinitialization for instrument panel viewing device
First Claim
1. A method for reinitializing an aircraft instrument panel viewing device comprising an electronic assembly, embedded software and a viewing screen, the method comprising:
- detecting a fault associated with the aircraft instrument panel viewing device during an operation mode of the aircraft instrument panel viewing device, wherein the fault is determined to arise after a predetermined time of proper operation in the operation mode of the aircraft instrument panel viewing device; and
executing a verification test that resets and tests the embedded software that controls the aircraft instrument panel before execution of a different verification safety test that resets and tests the embedded software and the electronic assembly and clears a display of the viewing screen during the safety test, wherein no specific presentation of fault is displayed on the viewing screen during execution of the verification test.

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.

6. A system, comprising:
-
an aircraft instrument panel viewing device that comprises an electronic assembly, embedded software, and a viewing screen; a processor coupled with the aircraft instrument panel viewing device to detect a fault associated with the aircraft instrument panel viewing device during an operation mode of the aircraft instrument panel viewing device, wherein the fault is determined to arise after a predetermined time of proper operation in the operation mode of the aircraft instrument panel viewing device, and execute a verification test that resets and tests the embedded software that controls the aircraft instrument panel before execution of a different verification safety test that resets and tests the embedded software and the electronic assembly and clears a display of the viewing screen during the safety test, wherein no specific presentation of fault is displayed on the viewing screen during execution of the verification test.
