R-44 EP's Flashcards
Power failure above 500’
1-lower collective immediately
2-establish a steady glide approximately 70kts
3-keep collective between 97-108%
4-select landing spot
5-attempt restart if able
6-if unable to restart, turn off unnecessary switches and fuel valve
7-at 40agl begin flare
8-at 8ft level and raise collective
Power failure between 8 and 500ft
1-lower collective
2-adjust collective to stay between 97-108%
3-flare
4-at 8agl level and pull collective
Power failure below 8ft agl
1-apply right pedal to prevent yawing
2-let ac settle
3-raise collective
Max glide distance
1: Airspeed 90 KIAS
2: Rotor rpm 90%
3: Best glide ratio 4.7:1 or 1nm/1300ft agl
Air restart
1-mixture off
2-throttle closed
3-actuate starter
4-Mixture move slowly rich while cranking
Caution: dont attempt below 2000 agl
Emergency water landing power off
1-follow same procedures as with over land until contacting water. If time permits unlatch doors prior to contact
2-apply lateral cyclic on water to stop blades
3-release seatbelt and clear ac when rotors stop
Emergency water landing power on
1-Descend to hover above water
2-unlatch doors
3-passenger exit ac
4-fly to safe distance from passenger to avoid possible injury
5-switch off battery and alternator
6-roll throttle off to detent
7-keep ac level and apply full collective as ac contacts water
8-apply lateral cyclic to stop rotor
9-release seatbelt and quickly clear ac when rotors stop
Loss of tail rotor thrust during forward flight
1-failure indicated by nose right yaw which can’t be fixed
2-immediately enter autorotation
3-maintain atleast 70kias
4-select landing site,roll throttle off into detent and perform auto landing
Loss of tail rotor thrust during hover
1-failure indicated by most right yaw can’t be fixed
2-immediately roll into detent let ac settle
3-raise collective
Engine fire during start on ground
1-cranking
2-if engine starts run at 60-70% for short time,shutdown, inspect damage
3-if engine doesn’t start, shutoff fuel and battery
4-extinguish fire with extinguisher, dirt, wool blanket
5-inspect damage
Fire in flight
1-enter autorotation
2-battery off
3-cabin heat off if capable
4-cabin vent on if capable
5-if engines running perform normal landing and immediately shutoff fuel
6-if engine off shutoff fuel and execute autorotation landing
Electrical fire in flight
1-battery off
2-alternator off
3-land immediately
4-extinguish fire inspect damage
Tachometer failure
Use remaining tach or rely on governor and land as soon as practical
Governor failure
Grip throttle firmly the switch gov off finish under manual control
Oil light
Check eng tach for power loss Check oil pressure gauge If confirmed land immediately
