Safe aircraft avionics system interface

Abstract:

Disclosed is an aircraft (102) comprising an aircraft avionics system (108) configured to perform one or more functions, and an interface module (110). The interface module (110) is configured to: store, for each function, respective one or more test criteria; receive, from an entity (104) remote from the aircraft avionics system (108), a function request for the aircraft avionics system (108) to perform a certain function; test the certain function against one or more of the stored test criteria corresponding to the certain function; and, responsive to determining that the certain function satisfies all of the test criteria that correspond to the certain function, outputting the function request for use by the aircraft avionics system (108).
