Ground school walkthrough of starting an Enstrom F-28F helicopter. The instructor runs through pre-start checks, then demonstrates hot-engine start technique: throttle full open, mixture full rich, boost pump for 5 to 8 seconds, then mixture to idle cutoff before opening the throttle again.
Throttle off. Throttle's off. Collective down and locked. Down and locked. Fuel valve on? Yep. Check. Heater off. Which I had it on. Rotor clutch disengaged. Disengaged. Mixture at idle. Cutoff. Magnetic compass reading? Check. Altimeter set at field elevation. Radio is off. They are off. All switches and circuit breakers off. Collective down and locked. Down. Locked. Master on. Alternator on. Starter switch on. Trim motor circuit breaker in. Throttle full open. Mixture full rich. Boost. Pump on. 5 to 8 seconds. Boost. Pump off. Mixture idle. Cutoff Throttle closed, then open. Position check. Mission switch on to both clear the area. Clear on the right and indicate where to start. Mixture back out? Yep. And when it's lycoming, you'll have to. Okay. You'll have to feather it. Feather. Feather it? Yep. To keep it coming. Okay. Do it again. You can. You can try it without boosting it. Okay. Spin it about two or three seconds, and then push it in and do that. And if it doesn't go that one, then boost it. Okay. All right. So throttle's open. Mixture's rich. Boost. Bump on. Okay. Yeah. Yep. Way too much. I would. It's. It.
