S2-S/Normal Procedures

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:

Front

1. Inspect bubble for cracks
2. Inspect landing lights
3. Inspect airspeed anemometer
4. Inspect beacon and front nav lights
5. Inspect right skids and struts

Right Side

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