What does FCF stand for in aviation maintenance?

The term FCF stands for Functional Flight Check in aviation maintenance. A Functional Flight Check is a critical procedure conducted to ensure that all systems of an aircraft are operating as intended after maintenance or repairs have been performed. It involves verifying the functionality of various aircraft systems during flight, including navigational aids, flight controls, and engine performance. This check helps ensure airworthiness and operational reliability before the aircraft is returned to service.

The importance of an FCF cannot be overstated, as it serves to validate that all maintenance tasks have been completed accurately and that no issues remain that could affect safety during subsequent flights. This process is part of a comprehensive approach to maintenance that prioritizes operational readiness and safety for both the crew and the aircraft.
