Effect of the Design of Aircraft Systems on Type Rating Training

Abstract

According to the design of aircraft system as the technology progressed the gradually increased interdependence between systems may raise the workload for flight crew This research attempts to calculate the “quantity” of information that would transmit across the human-machine interface from a failure event The analyses are based on variations in configuration design of power generation systems (the electrical system fuel system air system and hydraulic system) of the Airbus A320 A330 and A350 and the Boeing 737 777 and 787 With the help of a verified self-developed method derived from fault tree model probabilistic analyses and Information theory failure characteristics of each system can be obtained The failure mode and the average information quantity of the entire aircraft can also be revealed by further analyses The Airbus A320 A330 and A350 have the average information quantity of 23 84 bits 21 12 bits and 32 69 bits; the Boeing 737 777 and 787 have the average information quantity of 25 72 bits 25 06 bits and 32 91 bits Via series of comparisons it can be concluded that the dependence on the electrical system is gradually more than the traditional hydraulic system For the Airbus A320 and the Boeing 737 there is a difference of +7 9% (relative to the Airbus A320); for the Airbus A330 and the Boeing 777 there is a difference of +18 7% (relative to the Airbus A330); for the Airbus A350 and the Boeing 787 featuring the more-electric technology there is a difference of +0 7% (relative to the Airbus A350) With those results some practical recommendations to the type rating training of the corresponding aircraft fleet or even the transition training between two different aircrafts can consequently be made
