Final answer:
If an ELAC fails, other flight control computers take over its functions, and pilots follow specific failure management procedures. Aircraft are designed with redundancy to maintain aviation safety, and pilots are trained for such situations.
Step-by-step explanation:
If a single ELAC (Elevator Aileron Computer) were to fail on an aircraft, the plane's remaining flight control computers would typically take over the functions that the failed ELAC was responsible for. Most modern aircraft are designed with redundant systems to ensure that a single failure does not lead to a loss of aircraft control. Depending on the specific aircraft model, the functions of an ELAC may include controlling the ailerons, elevators, and other control surfaces. In the event of a failure, pilots are often alerted by an indication on the flight deck and may follow specific procedures outlined in the airplane's manual to ensure safe continuation of the flight. The redundancy in aircraft systems is a critical aspect of aviation safety, and pilots receive extensive training to manage such failures effectively.
