Avionics technicians perform a wide range of tasks within the fields of electronic maintenance and repair. They are responsible for the electronic parts within an aircraft and all the wiring that connects the components to the electrical system. They ensure all parts and wires work, both individually and together, to guarantee the integrity of the aircraft. Their work often focuses on the equipment of fixed-wing aircraft and helicopters. Avionics technicians make sure that the components are clean, in good repair, and functioning properly to guarantee the safety of the passengers and crew aboard an aircraft. On a daily basis, an avionics technician might install new equipment, troubleshoot malfunctioning avionics machinery, and clean soiled components. They are also in charge of wiring navigational components, autopilot systems, and passenger entertainment devices.
