What is the first item in the abbreviated Takeoff Checklist?

• A. NR Switch as Required
• B. Center Instrument Panel 'Checked'
• C. RADALTS as Required
• D. Wheels Up/Confirmed Down

Answer: (A)

The first thing to verify in the abbreviated Takeoff Checklist is rotor speed control. The NR switch sets how the rotor speed (Nr) is managed during takeoff, which is fundamental for establishing a safe and reliable lift-off. By selecting NR as required, you ensure the rotor speed governor (or manual mode if used) will bring and hold Nr in the proper range as you increase power and begin to climb. If Nr isn’t correctly set first, you may not get predictable rotor response, risking an overspeed or an inability to achieve the desired climb rate. The other items shown—instrument panel checks, RADALTS readiness, and wheels status—are important, but they don’t establish the critical rotor speed control needed at the moment you’re preparing to lift off. Once Nr is properly configured, you can proceed with the remaining checks with a clearer, more controlled takeoff.
