Emergency procedures
Land immediatley
Land on nearest clear area where safe normal landing can be performed. be prepared to enter autorotation during approach, if required.
Land as soon as practical?
Landing site is at pilots discreriin based on nature of problem and availible landing areas. Flight beond nearest airport is not recommended.
symtom på power failure?
Low RPM horn
change in noise level
nose left yaw
oil pressure light
decreasing engine PRM
Symptom Drive system failure?
unusual noise or vibration
nose right or left yaw
decreasing rotor PPM while engine RPM is increasing
maximum glide distance configuration?
90 KIAS, Rotor rpm 90%
minimum rate of decent configuration?
55 KIAS, Rotor RPM approximatley 90%
autorotation PRM minimum under 500 feet?
97%
hur stoppar man upp rotorn vid nödlaning i vatten?
lateral cyclic
symtom loss of tail rotor thrust?
nose right yaw which cannot be corrected by applying left pedal
action Loss of tail rotor thrust in fwd flight?
Immediatly ener autorotation
Maintain 70 KIAS if practical (hjälper till att hålla nosen rak)
select landing site
roll thottle into overtravel spring, and perform autorotation landing
headset audio failure?
lnd as soom as practical, pilot will not hear liw RPM horn with failed headset.
Motorbrand vid start?
fuel mixure off
fuel valve off
battery swich off
rotor brake, if time permits
exit helicopter
Engine fire in flight?
enter autorotation
cabin heat-OFF
cabin vent -ON
ENGINE RUNNING
- perform normal landing, then fuel valve/mixure OFF
ENGINE STOPS
-fuel valve OFF and complete autorotation landing
battery swich -OFF
rotorbrake
exit helicopter
electrical fire in flight?
Battery and Alternator -OFF
open cabin vents
land immediatley
fuel mixure OFF and fuel valve OFF
if time permits apply rortobrake
exit helicopter
Vad slutar fungera och är risk när batteri och alternator switches båda är OFF?
Low PPM system
Governor
Tachometer failure?
allow govenor to control rpm,
Land as soon as practical
hur är Tach, govenor och low rpm kopplade?
samtliga har separata power circuits.
en special citcuit gör så att batteriet kan förse tachs med ström även fastän BATT/ALT är OFF.
-är dock batteriet slut, fungerar inte tachs!!
symtom på låg hydraul olja?
tillfällig eller konstant vibrationer i controls
action Hyd system failure?
Verify HYD- ON
If hyd not restored- HYD-OFF
adjust airspeed and flight vondirion as desired for comfortable control.
Land as soon as practical
govenor failure?
Grip throttle firmly to override govenor,
switch hovenor off
complete flight using manual throttle control
Olje lampan tänds vad gör du?
Lampan indikerar loss of engine power or oil pressure.
kolla tach för powerloss.
kolla oil pressure gage- om trycket är lågt - landa direkt!
action Om en lampa tänds?
om lampan tänd och noise,vibration, temp raise occurs- Land immediatly
om ingen annan indikation, land as soom as practical.
hur mycket o hur länge kan man flyga med liw fuel lamp?
3 gallons( 11 Liter), max 10 min i cruise power
action cluch light?
låt ej lysa mer än 10 sek, dra cuircut breaker vid 9
Action ALT light?
indicates low voltage and possible alternator failure.
turn off all non essential electroc equioment and switch ALT OFF and back ON to reset alternator control unit.
it lightstays on, land as soon as practical.
-fortsatt föygning utan alternator kan resultera i att batteriet dras ur och tachometerna slutar fungera som kan ge farliga flygsituationer.
Action Starter ON?
indikerar att startmotorn jobbar.
if light not go out after ignition swich is relesed from start position, immediatly pull mixture off and tyrn off battery swich off. Have starter motor serviced.
Action Low PRM light?
indikerar rotorvarv under 97%
sänk omedelbart collective, apoly aft cyclic.
Light is disabled when collective is full down.
action Carbon monoxide
shut of heater
open nose and side vent doors
om huvudvärk, ysel i samband med light, land immediatly.
action Full Throttle
indicates engine near full throttle. Govenor will br inefective beacuse can not increase throttle to maintain RPM.
Lower collective as required to extringuish light.

när är störst risk för carburettor ice?
OAT -4c och +30c och skillnad mellan dewpoint och OAT med än 15 grader
how to avoid blade slap?
fenerally occurs when airspeed is below 100 KIAS. Use fairly sterp approach until saitspeed is below 65KIAS
