Which system takes over control of aileron trim if the primary system fails?

The Auxiliary Artificial Control Unit serves as a critical backup system in aircraft, particularly in ensuring control surfaces like ailerons can be adjusted for optimal flight performance if the primary control system fails. In the Dassault Falcon 2000LXS, the integrity of aileron trim is essential for maintaining aircraft stability and handling, particularly during flight maneuvers and in response to varying load conditions.

When the main system is compromised, the Auxiliary Artificial Control Unit automatically takes over the management of aileron trim, allowing the aircraft to continue to be managed effectively. This redundancy is crucial for safety, as it helps prevent potentially hazardous situations that could arise from loss of control. In contrast, the emergency backup control system and manual controls do not provide the same level of automated trim control, while the main control panel does not have the capability to take over for trim functions specifically. This distinction highlights the importance of the Auxiliary Artificial Control Unit in maintaining control and ensuring the aircraft remains operable even in the event of a primary system failure.
