Answer 49

Hydraulic power-operated systems
Boosted flight control systems are found in aircraft lighter than approximately 60 tons, in heavier aircraft, the servo tabs would be too big and need too much force for manual operation of the system. Another problem with a power-boosted control systemis that during transonic flight shock waves form on the control surfaces and cause control surface buffeting, and this force is fed back into the control system.
