Avionics technician

An avionics technician


Avionics technicians install, test, inspect and adjust electrical and electronic equipment such as navigation, communication and flight control systems in aircraft and spacecraft. They carry out maintenance and repair work. They perform functional tests, diagnose problems and take corrective action.

The duties of an avionics technician include, but are not limited to:

  • Installing and testing complex avionics equipment and electrical systems on aircraft or spacecraft.
  • Ensuring that all avionics equipment works properly before take-off and that they do not interfere with any other electronic device.
  • Removing, repairing, and re-installing any problematic avionics equipment before an aircraft is cleared for take-off.
  • Performing intricate and highly reliable soldering on components for navigation, missile control, and communication.
  • Assembling and installing electrical components.
  • Providing accurate diagnoses of difficult avionics problems.
  • Organizing ground support and test equipment for flight tests.
  • Analyzing flight test data to diagnose malfunctions and study the operations of the electrical components.
  • Coordinating all work with of engineers, technicians, and aircraft maintenance staff.
  • Keeping detailed records of all repairs and work performed on the aircraft.

Working conditions

Avionics technicians work in hangars, in repair stations, or on airfields. They must meet strict deadlines while following safety standards.

Most of these technicians work near major airports. They may work outside on the airfield, or in climate-controlled shops and hangars. Civilian aircraft and avionics equipment mechanics and technicians employed by Armed Forces work on military installations.

Injuries and Illnesses

Avionics technicians often lift heavy objects, handle dangerous chemicals, or operate large power tools. They may work on scaffolds or ladders, and noise and vibrations are common, especially when engines are being tested. Workers must take precautions against injuries, such as wearing ear protection and brightly colored vests to ensure that they are seen when working around large aircraft.

Work Schedules

Avionics technicians usually work full time on rotating 8-hour shifts. Overtime and weekend work are common.

Minimum qualifications

An associate’s degree in avionics or aviation technology is generally required to work as avionics technician.

In some jurisdictions, avionics technicians must hold a license from an aviation authority such as the FAA.

ISCO skill level

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

  • the nature of the work performed in an occupation in relation to the characteristic tasks and duties
  • the level of formal education required for competent performance of the tasks and duties involved and
  • the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Avionics technician is a Skill level 2 occupation.
