couger39 Posted June 7, 2015 Share Posted June 7, 2015 Hi allToday once starting No 4 Engine rpm went upto 60 % and then the rpm unwinded. The temperature was around 40 Deg Charlie....Request reasons based on experience... Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted June 8, 2015 Share Posted June 8, 2015 Need more info, ie, throttle position, auto/null, max TIT reached, a/c packs both off, if GTC aircraft was ATM off, what was starting time at 60%? Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted June 12, 2015 Share Posted June 12, 2015 Agree with pjvr99 Check your blade angle and make sure it is correct for ground idle.Start another engine and use higher pressure air.Try a NULL start (watch the TIT) may exceed 850 Quote Link to comment Share on other sites More sharing options...
ec130 Posted June 14, 2015 Share Posted June 14, 2015 agreed, more information. button out is at 60%. so did you button out and rpm decayed? did it flame out? more info please. Quote Link to comment Share on other sites More sharing options...
Railrunner130 Posted June 15, 2015 Share Posted June 15, 2015 I'm a Loadmaster, so I'm going on my minimal engine knowledge. Was the airplane aimed into the wind? Hot tail winds aren't friendly to engines. Quote Link to comment Share on other sites More sharing options...
