Before Starting Engine
Adjust pedals, ensure seat belts and doors are latched, check controls, and set throttle to OFF.
Starting Engine
Follow a series of steps including setting the collective, turning on switches, and monitoring oil pressure.
Rotor Engagement
Check collective, pedals, and cyclic before engaging the rotor clutch slowly.
Operational Checks
Advance throttle and check various parameters including fuel flow and manifold pressure.
Shutdown After Landing
Follow steps to safely reduce throttle, disengage clutch, and turn off all systems.
Safety notes
- If the engine fails to start in 2-3 seconds, release the starter button and prime the engine.
- Engine should not run rough on a single magneto.
- Monitor oil pressure; it should be above 25 PSI after starting.
- Idle the engine for 2 minutes or until CHT cools below 300ºF before shutdown.
