50
What’s the procedure for fire on the ground?
``` If cranking, continue to suck flames out. If engine starts, run at 60-70% Fuel mixture - Off Fuel valve - Off Battery - Off Exit Helicopter ```
51
What’s the procedure for engine fire in Flight?
Enter autorotation Cabin heat off Cabin vent on If engine running, Normal landing then cut mixture/fuel valve If engine stops, fuel valve off, auto landing Battery switch off Exit Helicopters
