Good Morning All,This morning I was flying from London Gatwick to Amsterdam and after a smooth take off I climbed into the clear skies over London.At 2,000ft I switched on Auto Pilot (VNAV & LNAV). While climbing the aircraft went into a stall. I switched off the autopilot and started a slight dive to re-again the speed.Then the aircraft started to climb again, and then lot speed! I noticed that LNAV kept on turning off, about ever minute, to a minute and a half...I carried on for 20 minutes, switching on and off and on auto thrust, auto pilot, everything - but nothing helped.Landed in EHAM and re started flight sim, and the problem with LNAV disengaging was no more!Has anyone else had this problem? I have been flying the PMDG Boeing 73NG from the day of release and this is the first time this has happened!Odd.Warm RegardsKimberly. :-outta

Hi Kimberly,Did you perhaps open a panel (zoom or whatever) without using our panel switcher ? This has been reported to cause stange MCP behaviours. cheersanthonyAnthony MertonPrecision Manuals Developmenthttp://www.precisionmanuals.com

Hi Ya,I did not switch the panel, I did however load the Air Europa first but then found out that the night lighting does not work on that aircraft. I then loaded the SAS B736.Thanks for your helpKimberly. :-outta
