ENGEngine failure in a hover?
Hovering autorotation: hold heading, slight settle, cushion with collective, land level.
ENGEngine failure at altitude?
Enter autorotation (collective down, airspeed, RPM, spot); always know your landing spot.
OEIOEI Task applies to?
Multiengine helicopters only — N/A to the single-engine R44.
VRSThree VRS conditions?
Powered flight, descent > ~300 ft/min, airspeed below ETL. Adding collective worsens it.
VRSVRS recovery?
Forward cyclic to regain airspeed/ETL (or Vuichard). Prevention: keep airspeed up, limit sink.
RPMLow rotor RPM recovery?
Lower collective and manage throttle/power per POH; condition a response to the low-RPM horn.
ROLLDynamic rollover recovery?
Smoothly lower the collective — not opposite cyclic.
LOWGRobinson low-G recovery (SFAR 73)?
Immediately apply gentle aft cyclic to restore positive G BEFORE any lateral cyclic; never abrupt forward cyclic/pushover (mast-bumping risk).
LTELoss of tail-rotor effectiveness?
Uncommanded yaw at low airspeed/high power in certain winds; pedal, reduce collective if able, gain airspeed.
IIMCInadvertent IMC (VFR heli)?
Control by instruments, climb for terrain, turn toward VMC, get help; don’t scud-run.
