Well, some of them anyway. All of a sudden two of my aircraft...iFDG/PSS Airbus mrege and the the SGA DC-9 with Stellen Hilmerby's fine panel...will not start manually anymore. Both will start using the control "E" key strokes, but that is the only way. I have tried resetting all defaults and have done the alternate "start running" and "cold and dark" start routines to no avail. Oddly enough all of my other aircraft will still start manually. Anyone out there experienced this and if so do you know of a solution?? Thanks in advance. By the way I'm running FS9.1 Mike

Same here with my FSD Navajo ... It won't start... even after I have reset the damages.It also won't remain started after I use the MS Default twins and then load the FDS Navajo. I want to get their Piper Seneca... but on the account of this I won't.The Navajo engine failes too easily..Its way too exagerated. if its like this in the real world... then no one..I mean no one will fly this trash plane.I don't want set the realism level lower... cause.. I don't want the dynamics of the aircrafts to be any less realistic.

Hi Mike,Have you tried deleting the STATE.CFG file in the aircraft's folder.It can be found in X:DOCUMENTS AND SETTINGS[your user profile folder]APPLICATION DATAMICROSOFTFS9[your particular aircraft] where X: is your hard drive letter where your user profile is stored.John

Would this help? My state files only contain engine times

Thanks for the suggestion John, but the problem still exists.Mike

Thanks to all who took the time to read and those who offered suggestions, but I found the problem. For those of you who may curious as to the problem let's just say it was operator error. Sorry for the inconvenience.Mike

My Navajo had engine problems (right engine wouldn't keep running) but I fixed it with scheduled maintainence in the Navajo load managerStatus & Repairs click "options".
