Transition to Forward Flight: After ETL, adjust attitude to 8-10 degrees nose down and adjust the cyclic to continue the acceleration to which speed?

Transition to Forward Flight: After ETL, adjust attitude to 8-10 degrees nose down and adjust the cyclic to continue the acceleration to which speed?

• A. The Desired Climb Airspeed
• B. The Maximum Speed
• C. The Economy Speed
• D. The Safe Speed

Answer: (A)

The main idea is how you pick the speed during the transition from hover to forward flight. After you reach effective translational lift, you tilt the helicopter slightly nose-down and use the cyclic to start moving forward. The speed you continue to accelerate toward is the desired climb airspeed—the speed chosen to optimize climb performance and rotor efficiency during forward flight. This target ensures you have enough translational airflow over the rotor to maintain lift and control, while keeping engine and rotor RPM in the green and avoiding rotor stalls. Accelerating to the maximum speed or to a generic “safe” or “economy” speed isn’t the objective here; the procedure calls for ramping up to the designed climb speed to transition smoothly and safely into forward flight.
