Flight control computer

A flight control computer (FCC) is a primary component of the avionics system found in fly-by-wire aircraft.

[1] A flight control computer receives and processes data from a multitude of sensors throughout the aircraft.

These sensors monitor variables such as airspeed, altitude, and attitude (the aircraft's orientation in three-dimensional space).

Embedded within integrated avionics packages, it executes critical functions such as guidance, navigation.

[3][4] In the Boeing 777 there are three primary flight control computers located in the aircraft's electronic equipment bay, responsible for computing and transmitting commands for normal mode flight control surfaces to maintain normal flight, including rudder, elevators, ailerons, flaperons, horizontal stabilizer, multi-functional spoilers, and ground spoilers.
