Under what condition would a pilot use the Manual Override (MOR) Handle?

The best condition for a pilot to use the Manual Override (MOR) Handle is when flying over mountainous terrain above 8,000 feet MSL. At higher elevations, especially in mountainous areas, the terrain can present significant challenges for navigation and control. Using the MOR Handle allows the pilot to have direct control over the aircraft's systems, providing better handling and responsiveness in potentially turbulent or unpredictable conditions.

In situations where altitude and terrain complexity factor in, manual control becomes essential for maintaining safety and ensuring that the aircraft can respond appropriately to any changes in the environment. This is particularly crucial when flying at high altitudes where air density is lower, and aircraft performance may be affected, making the use of automatic systems less reliable or effective.

When comparing this situation to routine landings or operations on flat terrain under lower altitudes, the need for manual control diminishes significantly. In those scenarios, flight systems are generally well-suited for the task and can manage the conditions without additional intervention from the pilot.
