MD11 jumping on take off and loosing speed

Recommended Posts

It sounds like Microsoft put in those crazy runways that they had in FS9, the ones with the Bitimus Surface. Is the runway black? try taxiing on the runway and if the airplane bounces then thats the problem. You need to change the runway type using an AFCAD editor or something

Hi thereIts not a problem with the runways...Did what you suggested and nothing happened... Also tried it with the PMDG 744X, nothing again. Just seems to be the MD11 :(Its very odd indeed and because of the 'jumping' and loss of speed it makes take off somewhat scary.I did not the problem on FS9 - however it never used to make a loss of speed, only the aircraft bouncing...Kimberly.Ps. Thanks for your help sugar :)

I don't have this aircraft yet,but it may have something to do with the instrument programming or framerates.Have PMDG supplied some optimization for updating instrument readings to accomodate different levels of hardware? Just a suggestion.Ron

I'm having exactly the same problem. After rotation, once the aircraft is established in the climb, the speed suddenly drops and the trend vector shoots downwards. Then when the ATS changes to climb, the aircraft slows again (because the AP fails to pitch over quickly enough) and the aircraft nearly stalls. I have deleted all of the winds in the weather pages and ticket the box which says "disable turbulence effects on aircraft" but neither have solved the problem.Regards,Martin

Unless you select clear air (no weather) the MSFS wx engine can throw a wrench in the works. The only solution that I have found (besides no weather) is to use registered version of FSUIPC and smooth the wind/pressure changes. I use 1 deg/kt per 5 seconds. This seems to provide a realistic dynamic pattern. Turbulence is a different thing altogether, and should be turned off for the simple reason that it is very unreal so why bother with it. However, turbulence will not creat the sudden changes in IAS to the degree or magnitude that wind/pressure creates.
