Final answer:
The RATS can be overridden by advancing the throttles to full forward, which allows pilots to access maximum thrust in situations requiring increased performance such as emergencies.
Step-by-step explanation:
The Reduced Authority Thrust System (RATS) can be overridden by advancing the throttles to their full forward position. RATS is used in aviation to provide the functionality where an aircraft operates with a pre-set, reduced thrust during takeoff to save fuel, reduce noise, and decrease engine wear. In case a pilot desires or requires full power - such as during an emergency or situation demanding maximum performance - they can override this system by pushing the throttle levers fully forward.
It is important for pilots to be aware of this override capability in critical situations to have access to the maximum available thrust the engines can produce. Overriding RATS may be crucial during a rejected takeoff or when encountering situations requiring immediate and significant altitude gain.
