mickylearjet Posted March 30, 2015 Share Posted March 30, 2015 737 stalls after a while at altitude 36000, also I get over speed alarm when I am only doing 285knts to which I can't seem to speed up. I have all gear up, and flaps to zero. Any ideas. Cheers Micky Link to comment Share on other sites More sharing options...
mrzippy Posted March 30, 2015 Share Posted March 30, 2015 Ideas? Yes! Pitot tube heat on?? Speed set to MACH, maybe .72 plus or minus. Still thinking about a new flightsim only computer! Link to comment Share on other sites More sharing options...
Double J Posted March 30, 2015 Share Posted March 30, 2015 285 at 36000 sounds right on the money. Remember 285 at FL36 is the same as 450 mph on the ground. Stalling? Did you start from ctrl e or did you cold start it? If you did cold start your fuel tanks might need to be switched. Link to comment Share on other sites More sharing options...
torkermax Posted March 30, 2015 Share Posted March 30, 2015 Actually 285knts IAS at 36000 is extremely high speed. 265 be about M.76 and its a very fine line at that altitude. Plane could have broke up if an over speed warning and crash detection is turned on. Should be using Mach indicator above FL240.

lnuss Posted March 30, 2015 Share Posted March 30, 2015 Just an additional note: your problem is in understanding what IAS (Indicated Air Speed) is. RAM air pressure drives the airspeed indicator, and the thin air at altitude provides less pressure into the pitot tube than the same ACTUAL speed near sea level, thus the recommendations to rely on your mach meter at higher altitudes, since it works on a different principle.

torkermax Posted March 30, 2015 Share Posted March 30, 2015 very good point Larry. That is why we use Mach speeds above FL240. Its calculated using the parameter you have describes... just for reference use approx M.64 for clmb above FL240 and cruise at .74. Much that depend on the aircraft but its a fairly sound reference.We generally us IAS for descent at 270 or 280 IAS...Of course that is all calulated in the FMC for Dummies......But "I wasnt always out of control" :p CPU: I7 4790K @ 4.5 ghz, GPU and CPU water cooled GPU: Gigabyte GTX 970 MEM: Gskill Rippjaw 1866 17900 MB: Gigabyte Gaming 5 Z97X Link to comment Share on other sites More sharing options...
