Final answer:
The ELACs (Elevator Aileron Computers) control the pitch and roll of Airbus aircraft through the elevators and ailerons. They ensure safe and efficient operation by processing pilot inputs and adjusting the control surfaces.
Step-by-step explanation:
The FLT CTL PANEL refers to the Flight Control Panel, and the ELACs (Elevator Aileron Computers) are part of the flight control system in Airbus aircraft. These computers primarily control the pitch control through the elevators and the roll control through the ailerons. They process pilot inputs and sensor data to ensure safe and efficient aircraft operation by adjusting the control surfaces accordingly.
In the case of a dual ELAC system, one can serve as a backup to the other, enhancing the reliability of the aircraft's control system. The ELACs also work in conjunction with other computer systems on board, such as SECs (Spoiler Elevator Computers) and FACs (Flight Augmentation Computers), which manage other aspects of the aircraft's flight control surfaces and characteristics.
