Body Farm Posted May 7, 2016 Share Posted May 7, 2016 So what is the proper shutdown procedure for the Gazelle? Thank you [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Mt5_Roie Posted May 7, 2016 Share Posted May 7, 2016 (edited) So here's what i've done: 1) Turn of fuel flow 2) When rotors are spinning slower, start applying rotor brake 3) Turn off AP, pitot, trimmer, magnetic brake 4) Turn off Gyro, Nadir, RWR, any other system like weapons systems 5) Turn off Radios and countermeasure system 6) Turn off Fuel pump, battery, generator, alternator.

Excuse me, I don't mean to be rude. But I think turning off the fuel pump should be one of the first things you do. This ensures the engine 'sucks' out any fuel, leaving the pipes as dry as possible. After that, I think you should pull the yellow fuel lever, leaving the rotor spinning a bit. Shut-off the generator and alternater and all electrical power consumers. And then pull the red lever (rotorbrake) so the rotor stops spinning. I don't have any reference for this, it just makes more sense to me. Something that is not covered in the start-up mission is that you can switch-off the starter (DEM) switch after the engine is running.

Mt5_Roie Posted May 7, 2016 Share Posted May 7, 2016 So were learning something today. I'm actually working on the checklist that mimics the real Gazelle checklist and I decided to look up, since the steps above was what I just did. so here's the official from the manual method of stopping the engines: 1) Set the controls to neutral. 2) Move the fuel flow control level fully aft. CHECK: the 'ALARM' red warning light comes on. The rpm decreases. 3) Tighten the cyclic and collective pitch friction locks on the aircraft not fitted with the SAS (doesn't apply to us since we got SAS). 4) Return the starter to "OFF' position when the rpm and t4 temperature have stabilized. CHECK: The "STOP" (BLOC) red warning light comes on and then goes out. The "ENG P" (H.MOT) light on the failure warning panel comes on. 5) Set the booster pump switch to "OFF" (ARRET) 6) Wait until the "STOP" (BLOC) warning light goes out, and switch all switches OFF except for the magnetic brakes. CHECK: the failure warning panel lights and all the warning lights on the instrument panel go out. Next section is how to stop the rotor. Basically saying that when RPM has fallen to 170 or under apple the rotor brake. So looks like I was wrong in my list, hence why I'm working on the official checklists to be released.

Mt5_Roie Posted May 8, 2016 Share Posted May 8, 2016 Yep working on it. I have most of the standard procedures done, just need to work on emergency ones. Then testing...lots of testing.

Manuel_108 Posted May 9, 2016 Share Posted May 9, 2016 Interesting, so why does the engine keep running during flight when I turn the fuel pump and the master switch to off (A)? Is it because your system modeling is not interconnected enough? Link to comment Share on other sites More sharing options...
Charly_Owl Posted May 9, 2016 Share Posted May 9, 2016 4) Return the starter to "OFF' position when the rpm and t4 temperature have stabilized. CHECK: The "STOP" (BLOC) red warning light comes on and then goes out. The "ENG P" (H.MOT) light on the failure warning panel comes on. Question: why would a pilot leave the Demarreur (starter) on after engine has cranked up? Most of the helicopters I've worked on turn their starter off once IDLE NG has been reached and minimum NR is reached.

Mt5_Roie Posted May 9, 2016 Share Posted May 9, 2016 It's in the bug report to be tested. We'll keep you posted. Interesting, so why does the engine keep running during flight when I turn the fuel pump and the master switch to off (A)? Is it because your system modeling is not interconnected enough? Actual checklist has it going back to OFF after engine is started up. Question: why would a pilot leave the Demarreur (starter) on after engine has cranked up?

Manuel_108 Posted May 9, 2016 Share Posted May 9, 2016 Thanks for the quick answer! Only a pilot wanting to suicide would turn those two switches off simultaneously anyways. Link to comment Share on other sites More sharing options...
Body Farm Posted May 12, 2016 Author Share Posted May 12, 2016 Actual checklist has it going back to OFF after engine is started up. One problem I see (in DCS) is that doing so will lead to engine shutdown on autorotation simulation; once you pull back on the fuel lever the engine will die instead of staying on 25,000 RPM.

tusler Posted May 13, 2016 Share Posted May 13, 2016 Why not reduce engine to idle, then apply rotor brake ( at same engine speed it was originally released) and let the rotor spin down and then shut down the engine and all systems. I would think the engine idling would give you hyd press to control the rotor while it is slowing down to a stop. I don't know if hyd plays a part in this or not.
