Where is the best centre of gravity position with a stuck stabiliser?

The best center of gravity position with a stuck stabiliser would indeed be towards the aft of the aircraft—this involves moving passengers or fuel towards the rear. When the stabiliser is stuck, having the center of gravity further back can help mitigate control issues. An aft center of gravity can lead to a more stable configuration in flight, as it may counteract the nose-down tendency that occurs when the stabiliser is not functioning as intended.

In normal flight operations, the center of gravity is typically maintained within a specific range to ensure optimal performance and stability. When faced with a malfunction like a stuck stabiliser, adjusting the loading of passengers or fuel becomes a critical step to maintain manageable flight characteristics. By shifting weight towards the rear, the pilot can maintain better control of the aircraft and improve safety during the flight.

In situations where there is no specific malfunction, such as with a functioning stabiliser, the center of gravity is best kept centrally located to promote stability and control. An extreme forward center of gravity could exacerbate issues related to control effectiveness, especially in the context of a stabiliser failure. Hence, understanding the unique operational challenges posed by a stuck stabiliser influences this approach to weight distribution.
