- Functional monitoring all operation processes, if the detected condition could
arise and uncover complex failure modes or deteriorations [ 12 ].

An appropriate error code is stored for any recognized fault, which can be
designed as a warning signal in the diagnosis system (see Fig. 6.3 )[ 13 ].
In addition to possible disturbances in the main engine and in the exhaust gas
after treatment system, deteriorations in other components can also lead to
increased fuel consumption and higher exhaust gas emissions. Optimal control and
regulation needs a comprehensive electronic system.

6.3 Airplanes' Electronics

Airplanes' electronic equipment belongs to avionics. Equipment A manages
communication, navigation, aircraft control, flight management, and observation
of air traffic. Equipment B is installed for the control of life support, rescue, and
safety. Equipment C includes the passenger seats, the luggage lags, the toilets, and
the on-board kitchens. In military airplanes, this category includes the weapon
fittings, the photo equipment, and the parachutes [ 14 ].

6.3.1 Flight Management Systems

Flight Management Systems (FMS) integrate diverse and independently operable air-
craft electronic systems to aid the flight crew in managing the automatic pilot, optimizing
in-flight performance, and monitoring fuel consumption at flight deck displays [ 15 ].
