Final answer:
Maximum Continuous Thrust (MCT) must be recomputed when there are significant changes in aircraft weight, altitude, temperature, or engine condition. There is no fixed frequency, and recomputation is done using on-board computers or performance charts for optimal engine performance and safety.
Step-by-step explanation:
The term Maximum Continuous Thrust (MCT) is often used in the context of aviation, particularly when discussing engine performance and operation. MCT is a power setting on an aircraft engine that can be maintained for an unlimited amount of time without causing damage to the engine.
The frequency of recomputation of MCT is not fixed and can vary based on several factors including changes in aircraft weight, altitude, temperature, and the condition of the engine itself.
Recomputation of MCT might be necessary whenever there is a significant change in any of these parameters, and it is typically done using the aircraft's on-board computers or performance charts.
Pilots or engineers may also use engine management software that takes into account all the relevant variables to ensure that the engine is operated within safe limits. The goal is to achieve optimal performance while maintaining engine integrity and safety.
