Ron Attwood Posted February 26, 2019 Share Posted February 26, 2019 Has anyone else had this problem? Restarting the Yak after shutting down the engine? That is to say, returning to C&D, then trying to start up again. I've not yet managed it. Have to get a new plane. :noexpression: Link to comment Share on other sites More sharing options...
Wexler Posted February 26, 2019 Share Posted February 26, 2019 If you can walk away from a landing, it's a good landing. If you use the airplane the next day, it's an outstanding landing.

Ron Attwood Posted February 26, 2019 Author Share Posted February 26, 2019 (edited) I obviously haven't explained it very well. I'll try again. I have landed, very nicely. Taxied to the ramp and turned off my engine whilst I waited for a friend to join the server. Friend arrives and I attempt to restart the engine. Which it will not do! How's that? EDIT: No fool like an old fool. First ensure that the pneumatic system knob is rotated fully aft.

Wexler Posted February 26, 2019 Share Posted February 26, 2019 It was a joke, cant help you man. Mostly when this happens to me, i try to start from Ground power, then repair.

Wexler Posted February 26, 2019 Share Posted February 26, 2019 Oh, I probably got it now :-) Try the ground power.

Andy1966 Posted February 26, 2019 Share Posted February 26, 2019 would it turn over? maybe air supply was depleted. flaps and gear need to be in neutral position, they leak air, I'm pretty sure I have restarted before, I will check when I get home.

Charly_Owl Posted February 26, 2019 Share Posted February 26, 2019 The engine starter is pneumatic, which means it requires air pressure. Air pressure in the canister is expended by doing multiple engine starts and operating the flaps and landing gear. When you can't restart the aircraft, what's the air pressure indication you have?

It was my understanding that the air pressure wasn't effective right now (the air never goes down). Or is it working ? Link to comment Share on other sites More sharing options...

If it wasn't working, the valve would have no effect. As it definitely determines whether or not the engine will start, the air system by definition is working.

I meant that at the moment the air pressure related to the pneumatic systems never goes down as they should (if I understood the system correctly). For example, in the Mig-21, if you don't get your gear lever to neutral, you will soon be out of air and not able to brake after landing. Shouldn't it be the same in the Yak ?

MisterMac Posted January 7, 2021 Share Posted January 7, 2021 Sorry to necro this. But I recently got the yak and have run into this same issue i think. I take off, and land at a different airport, taxi and park, and then shut down for refuelling and repairs (if needed, which is usual so far). once I am refuelled and all that I go through start up and the engine wont start, it will not turn over. I am not sure if I have missed a step or what but I have been really scratching my head over it. every time I try to restart the engine I run into this issue. I am hoping that somebody here can help me out with a solution. Link to comment Share on other sites More sharing options...
Toriy Posted January 9, 2021 Share Posted January 9, 2021 (edited) To turn over the engine you need air pressure in the main air system (left needle on the gauge). When you switch off the engine, close the air valve on your left/behind to save your compressed air in the main air balloon.

Solution MisterMac Posted January 9, 2021 Solution Share Posted January 9, 2021 Hey Toriy, thank you for the advice. I checked the air gauge and it was good, and i fiddled with the air valve. no luck. However, I believe I found the solution. Prior to my testing and trying to resolve this, whenever I would restart the engine I would prime the cylinders several times and could never get the engine to start. I think I was flooding the engine or inducing hydro shock. I tried restarting twice today WITHOUT priming the cylinders, and the yak started both times without problems. It should be noted that I did prime the main line to get the fuel pressure where it needed to be, but again, I did not prime the cylinders. I am not sure if this will help anybody else, but I am happy that I have learned this, it was such a simple solution that had me stumped for days. 1 Link to comment Share on other sites More sharing options...
Toriy Posted January 9, 2021 Share Posted January 9, 2021 Thank you for info, MisterMac. Yes, this kind of priming may prevent engine from start, I also experienced this. Link to comment Share on other sites More sharing options...
