2.5 Emergency Start
2.5.1 Battery Start Procedures
- Rotor Brake – OFF
- Battery – OFF
- Accomplish all items in BEFORE STARTING ENGINE section as possible without turning on battery power.
- Start Mode – MANUAL
- Battery – ON
- No. 1 Engine – START
- Speed Selector – SHUT-OFF
- Start Switch – PRESS
- Wait – Min. 10 sec. and N1 above 19%
- Speed Selector – IDLE then slowly increase to 45% N1
- Starter – ABORT (disengage starter)
- All Gages – CHECKED
- Speed Selector – Increase slowly with minimum torque to 103%.
- Start Mode – NORMAL
- No. 2 Engine – Start using normal procedures
2.5.2 Start with Emergency Fuel Levers
This procedure should be avoided except when absolutely necessary to complete mission.
- Start Procedures – As normal up through advancing speed control to IDLE
- Emerg. Fuel Lever – Advance slowly to accelerate N1 to 56%.
- Emerg. Fuel Lever – Close slowly
- If engine continues to run at 56%, follow normal procedures.
2.6 Flight with Emergency Fuel Levers
- The Emergency Fuel Levers (EFL) bypass normal fuel meter to control fuel flow directly.
- If using EFLs due to fuel controller failure, control will only be possible above the valve position at the time of the controller failure.
- Collective changes must be made very slowly with reference to N2 for the affected engine to avoid rotor stall, or engine overspeed.
- Increases in collective will require increases on the EFL. Decreases in collective will require decreases in the EFL.
