Final answer:
Two identical actuators are used to position the stabilator in an aircraft.
Step-by-step explanation:
The subject of this question is Engineering.
Two identical actuators, mounted back to back and located in the tail pylon assembly, are used to position the stabilator.
For example, in the design of an aircraft, the stabilator is a movable horizontal stabilizer that combines the functions of both the stabilizer and the elevator. The actuators control the movement of the stabilator, allowing it to change its angle of incidence and provide stability and control to the aircraft.
