Final answer:
The question is about the behavior of the FCM in Direct Mode and its impact on the P-ACE units.
Step-by-step explanation:
The subject of this question is related to AeroSim- Flight Controls, which falls under the field of Computers and Technology. The question is discussing the behavior of the FCM (Flight Control Module) in Direct Mode, specifically how it affects the P-ACE (Primary-Alternate Control Electronics) units. In Direct Mode, the FCM is disconnected from the P-ACE units, which means that no airspeed gain information is provided to the P-ACE units.
As a result, the control limits default to values set by hardware in the P-ACE units. This information is important for understanding the operation and behavior of the flight controls in a simulated environment.
