after slewing to pushback from gate i start engines and i find that the right throttle locks and i can only operate the left side i then have to restart the sim and reprogram my flight then it works any reason why this is happening and how can i fix this thanks

try pressing e 1 2 in quick sequence this will assign your throttle controls to both throttle axes it sounds like somehow your throttle control is operating only the left throttle see if that works never use a periodAll in good fun, of course :)Matt

Isn't there a custom key setting in FSUIPC for resetting control to two engines simultaneously? Can't say for sure, but I seem to remember seeing it. I found e12 doesn't work sometimes, especially with addon aircraft.Sorry if that's not right though... I don't have FS2002 here at work. Shame! ;)Cheers,Simon.
