balaton Posted October 5, 2017 Share Posted October 5, 2017 Hi Guys, After a couple of months and flight hours with the Belsimtek MI-8, I could hardly criticise anything in this product. In my opinion : simply the best helo in flysim world. Great immersion, challenge and reward! My only observation up to now that after a normal shutdown of the engines per the checklist procedure, my EGT will not decrease. They are simply maintaining the last indication, somewhat below 600 C. Anybody with the same experience? Is it a bug or perhaps my install or system? Appreciate your help, Tamas Link to comment Share on other sites More sharing options...
Slazi Posted October 6, 2017 Share Posted October 6, 2017 What happens if your start up again? Maybe it stops reading when it is off. Link to comment Share on other sites More sharing options...
balaton Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks Slazi, I will check it. But before I go into trubleshooting, I would like to confirm: do you have the same experience? I mean: when you shut down the engine by closing the fuel shutoff levers your EGT drops normally or hanging at the idle value? tamas, Link to comment Share on other sites More sharing options...
Slazi Posted October 7, 2017 Share Posted October 7, 2017 I haven't flown for a while, unfortuanately. Perhaps someone else? Link to comment Share on other sites More sharing options...
alfredo_laredo Posted October 7, 2017 Share Posted October 7, 2017 yes, it stays up for a little while around 600C then its goes to zero ill say about 10 min.. Im not sure if this instrument should stay on even with battery off but Im guessing it should not A.K.A. Timon -117th- in game Link to comment Share on other sites More sharing options...
balaton Posted October 7, 2017 Author Share Posted October 7, 2017 Thank you alfredo, its good to know that it is not my fault. Anyway, a jet engine shows a sharp and immediate drop in temperature when cutting off fuel. Tamas Link to comment Share on other sites More sharing options...
Holton181 Posted October 7, 2017 Share Posted October 7, 2017 ... Im not sure if this instrument should stay on even with battery off but Im guessing it should not They stay on without batteries, they are connected to thermocouples, self powered censors. https://en.m.wikipedia.org/wiki/Thermocouple The gauge is powered by the censor itself. /H Helicopters and Viggen DCS 1.5.7 and OpenBeta Win7 Pro 64bit i7-3820 3.60GHz P9X79 Pro 32GB GTX 670 2GB VG278H + a Dell PFT Lynx TrackIR 5 Link to comment Share on other sites More sharing options...
balaton Posted October 7, 2017 Author Share Posted October 7, 2017 Hi Holton, Just back from a test flight. You are spot on! Previously, I have followed the USAF shutdown checklist which dictates to switch gens, inverters and rectifiers OFF beforore setting ground idle and finally shut down. My thermocouples were left without power. Once again: amazing simulation! Cheers, Tamas Link to comment Share on other sites More sharing options...
AlphaOneSix Posted October 8, 2017 Share Posted October 8, 2017 The PTIT gauge requires 36V AC power to operate. Link to comment Share on other sites More sharing options...
Holton181 Posted October 8, 2017 Share Posted October 8, 2017 The PTIT gauge requires 36V AC power to operate.I stand corrected! But I know some EGT (PTIT) gauges on other aircrafts do move due to the power delivered by the thermocouple only, no need for other power sources for those.

balaton Posted October 11, 2017 Author Share Posted October 11, 2017 ... and finally let me correct myself. I refered to EGT in this thread which is wrong. Of course, it is PTIT! The values on the instruments tell the story (if you don't read the systems manual). They are too high for EGT for any turbine engine but just on spot for beeing power turbine inlet temp.
