True/False: The manual reset of the emergency flap brake valve is for ground use only.

• A. True
• B. False
• C. Not Applicable
• D. Both

Answer: (A)

In aircraft systems, certain maintenance actions are restricted to ground operations to protect flight safety. The manual reset of the emergency flap brake valve is one of those actions, because performing a reset in flight could cause an uncontrolled change in flap braking or position under aerodynamic loads, potentially leading to hazardous flight conditions. Electric or hydraulic power, plus the risk of sudden actuator movement, means resets are designed to be carried out only when the aircraft is on the ground and power can be secured, after inspection and with safety precautions in place.

So the statement is correct: the manual reset is for ground use only. If a fault occurs, the proper procedure is to handle it during ground maintenance and ensure the system is verified safe before flight.
