What action should be taken if severe vibrations and/or drastically altered flight characteristics occur?

• A. LAND/DITCH IMMEDIATELY
• B. LAND AS SOON AS POSSIBLE
• C. CONTINUE FLIGHT
• D. MAINTAIN ALTITUDE

Answer: (A)

When severe vibrations or drastically altered flight characteristics occur, the priority is to stop flying and get the helicopter on the ground or safely on the water as quickly as possible. Sharp changes in vibration or handling signal a potential imminent loss of control or a serious mechanical failure—continuing flight could worsen damage, lead to an unrecoverable situation, or cause a crash. Landing immediately minimizes exposure to the fault and gives you the best chance to assess and secure the aircraft. That’s why landing/ditching immediately is the appropriate action. Landing as soon as possible implies waiting for a more favorable moment, which can be dangerous if the fault progresses. Continuing flight or maintaining altitude ignores the clear risk signs and is not acceptable. After the landing, follow the standard emergency procedures and secure the aircraft as required.
