In normal operation, T-6B flaps are ______________ controlled and ________________ operated.

• A. Electrically; hydraulically
• B. Mechanically; hydraulically
• C. Mechanically; electrically
• D. Electrically; electrically

Answer: (A)

Flap movement is driven by hydraulic power, but the control signal that asks for a flap position comes from an electrical system. The pilot selects flaps through an electrical command, and that signal directs a hydraulic control system to push or pull the flap actuators. Hydraulics provide the high force and smooth, reliable actuation needed for large surface deflection, while electronics handle the command, feedback, and safety interlocks. This combination—electrical control with hydraulic actuation—fits the T-6B design, whereas purely mechanical or fully electric actuation would not meet the system’s needs for force, responsiveness, and redundancy.
