Hi allI use FSBuild to export my flightplans, and it works well with the JS41.Once exported, I open the FMC and import the FP.The problem doesn't happen everytime. When I try to change the departure or approach procedure, and there is NO stored procedure for the airport, the FP disappears and I have to import it again.Anyone having this kind of issue?Thanks in advance.

After clicking on the departure or approach selections, you have to re-enter the ICAO code for the location. The built flight plan shouldn't clear unless manually erased or not selected before doing other FMS functions.

Will check, thanks Dan.

Will check, thanks Dan.

The stored flight plan will clear if you leave the FPL page before selecting and confirming the plan (ie 'select LSK / Enter Button').Regards.Ernie.
