R44 Emergency Procedures Flashcards
Definition Land Immediately
Land on the nearest clear area where a safe normal landing can be performed. Be prepared to enter autorotation during approach, if required
Definition Land as soon as Practical
Landing site is at Pilot’s discretion based on nature of the problem and available landing areas. Flight beyond nearest airport is not recommended
Power Failure Above 500ft
- Lower collective immediately to maintain RPM
- 70kts or maximum glide/maximum endurance
- Keep RPM between 97% and 108%
- Select landing spot and, if altitude permits, maneuver to land into wind
- Air restart if possible
- Switches and fuel valve off
- Land
Power Failure Between 8ft and 500ft
- Lower collective immediately to maintain RRPM
- Keep RPM between 97% and 108%
- Maintain airspeed until ground is approached then flare
- Touchdown
Power Failure Below 8ft
- Apply Pedal to stop the yaw
- Allow heli to settle
- Raise collective to cushion the landing
Maximum Glide Distance Configuration
90 kts / 90% RRPM
4.7:1 = 1nm per 1300ft
Minimum Rate of Descent Configuration
55 kts / 90%
4:1 - 1nm per 1500ft
Air Restart Procedure
- Mixture Full Rich
- Throttle - Closed then crack
- Actuate Starter
Emergency Water Landing
Autorotate - unlatch doors prior to water contact
Loss of Tail Rotor Thrust in Forward Flight
Failure indicated by nose yaw right that cannot be stopped by left pedal
- Immediately roll throttle off into overtravel spring
- 70kts
- Raise collective just before touchdown to cushion landing (making sure throttle is in overtravel)
Engine Fire During Start on Ground
- Cranking - Continue and attempt to start
- If engine starts run at 60-70%
- Fuel Mixture - OFF
- Fuel Valve - OFF
- Battery Switch - OFF
- Stop Rotors
- Exit Aircraft
Engine Fire in Flight
- Enter Autorotation!
- Cabin Heat - OFF
- Cabin Vent - ON
- Engine Running - Land
- Engine Stops - Fuel Valve off and complete Autorotation
- Battery Switch - OFF
- Stop Rotors
- Exit Aircraft
Electrical Fire in Flight
- Battery and alternator - OFF
- Open Cabin Vents
- Land Immediately
- Fuel mixture and fuel valve OFF
- Stop Rotors
- Exit Airrcraft
Tachometer Failure
Use remaining Tacho to monitor RPM
If not clear which is malfunctioning , allow governor to control RPM and land as soon as practical
Hydraulic System Failure
- HYD Switch - Confirm ON
- If Hydraulics not restored. HYD Switch - OFF
- Adjust speed and flight condition for control
- Land as soon as practical
Governor Failure
If engine RPM governor malfunctions, grip throttle firmly to override the governor, then switch off governor. Complete rest of flight with manual throttle control
OIL Light
- Loss of engine power or oil pressure
- Check engine tach for power loss
- Check oil pressure gauge and, if pressure loss is confirmed LAND IMMEDIATELY
ENG FIRE Light
- Indicated Possible Fire in Engine Compartment
- Enter Autorotation!
- Cabin Heat - OFF
- Cabin Vent - ON
- Engine Running - Land
- Engine Stops - Fuel Valve off and complete Autorotation
- Battery Switch - OFF
- Stop Rotors
- Exit Aircraft
MR TEMP Light
Indicated Excessive Temp of MR Gearbox
If light is accompanied by any indication of problem such as noise , vibration, or temperature rise - land immediately
If there is no other indication of a problem - land as soon as practical 55kts
MR CHIP Light
Indicates metallic partials in MR Gearbox
If light is accompanied by any indication of problem such as noise , vibration, or temperature rise - land immediately
If there is no other indication of a problem - land as soon as practical 55kts
TR CHIP Light
Indicates metallic partials in TR Gearbox
If light is accompanied by any indication of problem such as noise , vibration, or temperature rise - land immediately
If there is no other indication of a problem - land as soon as practical 55kts
LOW FUEL Light
Indicates 11L of usable fuel remaining
Engine will run out after 10 minutes at cruise
CLUTCH Light
Indicates clutch actuator circuit is on
Light stays on until belts are tensioned
10 seconds or greater - Pull CLUTCH CB and land as soon as practical
Reduce power and land immediately
