Robinson R44 - Practice Autorotation - Power Recovery

PRACTICE AUTOROTATION - POWER RECOVERY
1. Adjust carb heat if required. (See page 4-12.)
2. Lower collective to down stop and adjust throttle as
required for small tachometer needle separation.
CAUTION
To avoid inadvertent engine stoppage, do
not chop throttle to simulate a power failure.
Always roll throttle off smoothly for small
visible needle split.
NOTE
Governor is inactive below 80% engine RPM
regardless of governor switch position.
NOTE
When entering autorotation from above 4000
feet, reduce throttle slightly before lowering
collective to prevent engine overspeed.
3. Adjust collective to keep rotor RPM in green arc and
adjust throttle for small needle separation.
4. Keep airspeed 60 to 70 KIAS.
5. At about 40 feet AGL, begin cyclic flare to reduce rate
of descent and forward speed.
6. At about 8 feet AGL, apply forward cyclic to level
aircraft and raise collective to control descent. Add
throttle if required to keep RPM in green arc.
CAUTION
Simulated engine failures require prompt
lowering of collective to avoid dangerously
low rotor RPM. Catastrophic rotor stall could
occur if the rotor RPM ever drops below 80%
plus 1% per 1000 feet of altitude.
