From a cold cockpit to ready-for-takeoff — by the checklist, every time.
By the end of this lesson you can:
Describe the sequence from pre-start through start, clutch engagement, run-up, and the before-takeoff check.
Explain why you clear the area and monitor RPM and gauges during engagement.
State what the governor and hydraulic checks confirm before flight.
Recognize abnormal start indications and the appropriate response.
1 · Always the checklist, never memory
Starting a piston helicopter is a precise, sequenced task where order matters and a skipped step can damage the engine, starter, or drive system. The R44 POH Section 4 (Normal Procedures) is the authority; the flow below is for understanding, not a substitute for the printed checklist.
2 · The typical sequence (generic overview)
Phase
What's happening / why
Pre-start
Controls, fuel, circuit breakers, throttle, and switches set per checklist; “CLEAR!” called and area visually clear of people and FOD.
Start
Engage the starter; engine fires and settles to idle. Confirm oil pressure rises promptly; watch for abnormal indications.
Clutch / rotor engagement
Engage the clutch; the belt actuator tensions and the rotor slowly spins up. Monitor the clutch light and confirm rotor turns smoothly with no abnormal noise.
Warm-up & run-up
Allow temperatures/pressures to stabilize; perform system checks (e.g., governor, hydraulics, magnetos/sprag, gauges in limits).
Before-takeoff
Final check: instruments green, controls free, governor on, hydraulics checked, area clear, briefing complete.
Your aircraft: exact switch positions, RPM targets, temperature/pressure limits, warm-up times, and the run-up check items are R44-specific — read and fly the R44 POH Section 4 checklist and Section 2 limitations. Do not adopt a number from a video or generic source.

3 · Watch: a complete R44 startup

5 · The checks that gate takeoff
Two checks deserve special attention before you lift: the governor (confirm it holds engine/rotor RPM in the green as collective changes) and the hydraulic system (the pre-takeoff check from Lesson 07 — confirm boost works and feel the unboosted forces). Add a clutch-light-out confirmation, gauges in limits, controls free and correct, and a clear area. Anything abnormal means shut down and investigate, not “watch it and go.”
Risk management (the “Consider”): the dangerous moments here are rushing the start (hot/flooded start, low oil pressure ignored) and engaging the rotor without clearing the area. Protect against both with discipline: call “CLEAR,” watch oil pressure on every start, bring the rotor up smoothly while monitoring, and treat any abnormal gauge, light, or noise as a shutdown item.
