as350b3 normal procedures
i wished the world could be more black&white when it comes to helicopters.
starting up and shutting down the arriel 2b engine is described in the operating handbook something like this:
- to start the engine, go from OFF to ON (flight) with the starting selector, except when below -20 deg C when you must wait until oil temp is >0 deg C before switching to ON.
- shutting down: after setting down the helicopter, wait 30 sec on full RPM (flight idle) and the go from ON to OFF directly with the selector
the technicians in marignane, france, told us that the shutting down procedure is to prevent carbon build-up in the engine.
what happened to the cooldown issue? i was at the american eurocopter factory, and the test pilot told me what the book said as stated above, but good procedures was to wait at IDLE both up and down.
what do you b3-pilots out there think? what do you use for procedures?
cheers,
