• 30 KIAS / 300 ft ROD / left pedal
• Decision: Land / go around

• If nose turns left or right, engine fire, or strong vibrations enter AR and analyze cause (engine, drive, TR)
• In all other cases: RPPAA (rotor RPM, power, position, analyze, action)

• Enter AR
  • Collective down, nose up, heading
  • 65 KIAS / 97-110 %RRPM (max glide: 75 KIAS / 90 %RRPM, increase to 97 %RRPM <500 ft AGL)
• Air restart (do not attempt before AR is established, if engine failure expected, or <2’000 ft AGL)
  • Mixture: FULL RICH
  • Throttle: Closed then cracked slightly (10°)
  • Starter: Actuate with left hand
• "Mayday, mayday, mayday, HB-..., making an emergency landing near ..."
• Perform AR landing
  • If time permits: Fuel valve OFF
  • At 40 ft AGL begin cyclic flare
  • At 8 ft AGL apply forward cyclic and raise collective

• Push right pedal
• Raise collective, when helicopter starts descending

• Grip throttle firmly to override governor
• Governor OFF
• Control RPM manually

• Enter AR with 70 KIAS
• Roll throttle into overtravel spring
• Perform AR landing, preferably on hard surface

• Roll throttle off into overtravel spring
• Raise collective

• Identify “critical speed” (lowest speed at which nose does not turn, when collective is raised at vario 0)
• If critical speed <40 KIAS: Land with critical speed on hard surface; avoid deaccelerating below critical speed
• If critical speed >=40 KIAS: Enter AR with 70 KIAS and perform AR landing with throttle rolled into overtravel spring

• Enter AR
• Cabin heater OFF and cabin vents ON
• If engine is running: Land normally, then mixture OFF and fuel valve OFF
• If engine is NOT running: Fuel valve OFF and complete AR to ground
• Master battery OFF
• If time permits: Apply rotor brake
• Exit helicopter 

• Crank (to suck flames into engine)
• If engine starts: Run 50-60 %RPM for short time (30s)
• Mixture OFF and fuel valve OFF
• Master battery OFF
• If time permits: Apply rotor brake
• Exit helicopter

• Master battery OFF and Alt OFF
• Control RPM manually
• Cabin vents ON
• Land immediately
• Mixture OFF and fuel valve OFF
• If time permits: Apply rotor brake
• Exit helicopter

• Lower collective
• Roll throttle on
• Apply aft cyclic

• Cabin heater OFF and cabin vents ON
• If light is accompanied by symptoms of CO poisoning (headache, drowsiness, dizziness):Land immediately

If oil pressure gauge confirms pressure loss: Land immediately

• If light is accompanied by indication of a problem (e.g., noise, vibration, temperature rise): Land immediately

• If light flickers or stays on >10 s: Pull clutch circuit breaker
• If light is accompanied by indication of a drive system failure (e.g., noise, vibration): Reduce power, prepare to enter AR, and land immediately
  

• Out of fuel in max. 5 min (all alu) or in 10 min (bladder) at MCP

• Use remaining tach to monitor RPM
• Allow governor to control RPM

• Switch off non-essential electrical equipment (i.e. landing lights, nav lights and outside CTR, TMA, RMZ, or approach also radio, navigation, and flarm)
• Alt OFF, after 1 s alt ON
• If light stays ON: Land as soon as practical

• Release rotor brake immediately

• If light stays on after starter button is released: Mixture OFF and master battery OFF

• Governor ON

• Reduce airspeed to between 60 KIAS and 0.7 V_NE, but no lower than 57 KIAS
• Minimize cyclic control inputs; do not overcontrol
• Depart area of turbulence or land as soon as practical

• Apply aft cyclic
• Do not apply lateral cyclic

• Cylinder Head Temperature Gauge und alle Warning Lights, ausser LOW RPM and MR TEMP light (nicht bei R22 NG)
• MR TEMP und alle Gauges auf unterem Teil Mittelkonsole ausser Amperemeter
• RRPM
• EPRM
• Intercom
• Com und Nav

• <=2'000ft AGL: S: 5km (1.5km, 0.8km) + Bodensicht; V: clear of clouds (w/ transponder); H: clear of clouds (w/ transponder)
• >2'000ft AGL bis <FL100: S: 5km, V: 1'000ft, H: 1'500m
