SECTION 4. NORMAL PROCEDURES

1 PREFLIGHT

A thorough pre-flight inspection is essential to the safe conduct of your flight. The following procedures are recommended:

  1. Inspect bubble for cracks
  2. Inspect landing lights
  3. Inspect pitot tube for blockage
  4. Inspect antenna for security
  5. Inspect right skids and struts. Ensure shocks not over compressed
  6. Remove right engine cowling
  7. Check all belts, fuel and exhaust lines
  8. Replace right engine cowling
  9. Inspect fan intake for blockage
  10. Inspect main rotor blades including inner and outer blades. Check all control linkages and dampers between inner and outer blades.
  11. Inspect tail rotor drive shaft
  12. Inspect right side fuselage
  13. Check horizontal stabilizer for security
  14. Check tail rotor gearboxes for security
  15. Check tail rotor for security and damage
  16. Remove hex nut on drive shaft and check oil level. Add if necessary.
  17. Inspect left-side fuselage
  18. Ensure baggage door closed
  19. Remove left-side engine cowling
  20. Check air filter, generator security, exhaust and fuel lines.
  21. Check engine oil level.
  22. Check main rotor transmission fluid level.
  23. Replace left-side engine cowling.
  24. Check fuel level.
  25. Drain both fuel sumps on belly and ensure no water or contaminants in fuel.
  26. Inspect left-side skids and struts. Ensure shocks not over compressed.
  27. Turn main rotor blades backwards to ensure centrifugal clutch is disengaged.

2 STARTING

Use the following procedure for normal starts:

  1. Controls – neutral
  2. Collective – full down
  3. Throttle – idle
  4. Mixture - lean
  5. Beacon – on
  6. Fuel Cutoff – on
  7. Switches (Bat., Gen., Fuel Pump) – on
  8. Rotor Brake – on
  9. Collective – raise slightly, then lower (verify low rpm horn sounds)
  10. Volts – verify > 9 volts
  11. Mags – both
  12. Throttle full and Mixture full rich for 4 seconds, then back to throttle idle and mixture cutoff. (This primes engine for start. Avoid priming too long to prevent flooding of engine*)
  13. Starter – press and hold until engine starts
  14. Mixture – Full rich as soon as engine starts
  15. Rotor brake – off
  16. Oil Press – Wait for > 25 psi
  17. Cylinder Temp – Wait for > 100 C
  18. ELT - ARMED
  19. Transponder – ALT
  20. Radios - set
  21. Throttle – slowly increase to 2000 RPM.
  22. Throttle – chop quickly. Verify needle split then back to 2000 RPM.
  23. Fuel pump – off (verify brief drop in fuel pressure)
  24. Fuel pump – on
  25. Throttle – slowly increase to 2900 RPM
  26. Mag check
    1. Mags – left (verify drop 50-150 RPM)
    2. Mags – both (rpm returns to 2900)
    3. Mags – right (verify drop 50-150 RPM)
    4. Mags – both
  27. Governor – on
  28. Lights – As Required


  • Note: If you flood the engine, clear the flood by cranking the starter 2-3 seconds with mixture at FULL. Then move mixture back to LEAN and attempt to start again.

To bypass the normal procedure and start immediately, you can use the "Fast Start" button on the "@Cheats" menu.

3 SHUT DOWN

Use the following procedure to shut down the engine:

  1. Controls – neutral
  2. Collective – full down
  3. Governor – off
  4. Throttle – decrease to 2000 RPM
  5. Cylinder Temp – stabilized (about 160C)
  6. Throttle – idle
  7. Mixture – cutoff
  8. Mags – off
  9. Rotor brake – on (when below 200 RPM)
  10. Switches (Bat., Gen., Fuel Pump) – off
