A Systematic Design Method of Civil Aircraft Flight Crew Alerting System

Abstract

Crew alerting is a primary channel that provides awareness for the flight crew. It forms a complete and consistent human-computer interaction interface with the related information display and operation, to ensure the accuracy and efficiency of crew operation. It is the key link for the flight crew to intervene in the aircraft system and constitutes the last line of defense for the civil aircraft. Considering the essential role of flight crew alerting system in the pilot-system loops, design of flight crew alerting system is an important activity in civil aircraft systems engineering, with major impact to the operation safety of the airplane. However, due to the large number of aircraft airborne systems and the highly complex cross-linking relationship between the system, it is challenging to design correct and complete the crew warning system, and the related safety issues are also very prominent. In this paper, a systematic approach was proposed in the design of flight alert information, closely combined with system safety design and human-machine interaction design, to guarantee the correctness and completeness of aircraft flight alert information. The approach proposed in the paper, combined with the aircraft system safety design method, will improve the accuracy and integrity of the crew alerting design.
