Aircraft Instrument Systems

Maintenance technicians must be familiar with the various types of instruments used to convey information to the pilot. Some are flight instruments that depict the attitude, airspeed, and altitude of the aircraft. Other instruments provide information such as engine operational parameters and electrical system performance. While the FAA prohibits aircraft technicians from performing any maintenance or repairs to the actual instruments, they must be able to inspect them to verify their proper operation and installation. In addition, technicians must maintain the components that support the instruments, such as electrical wiring and fluid-line plumbing.
