Is there anyway to edit your IFR flight plan once you are airborne?For instance I would like to change alt or destination in mid air.TIA

If you are using FS2004, yes. Just bring up the ATC menu and then click on Change IFR destination (or something like that). It'll take you to the flight planner and then you can specify a starting point and your new destination.CAUTION: When FS asks you whether you want to position your plane to the new airport, say NO

Hi Steven,What should you put for starting postition? I would like it to start from my current position, but I have not found a way to do this. Tony

Just pick any airport that's close to your present position.
