What is the maximum pitch angle permissible in either direction?

• A. 25 degrees
• B. 35 degrees
• C. 30 degrees
• D. 20 degrees

Answer: (C)

Pitch attitude is limited to keep the helicopter inside a safe flight envelope. The maximum allowed nose-up or nose-down attitude is 30 degrees, so you won’t exceed the airframe and rotor limits or lose adequate control authority. Choices like 35 degrees would push beyond the safe envelope, while 25 or 20 degrees are more conservative than the specified limit.
