Hi Henk,
I apologize for the late reply. I use http://www.simroutes.com/fb2/showplans.aspx for finding good routes, or creating actual routes by selecting STARS, SIDS and enroute fixes. You can also generate manually a complete route one fix at a time as well. Simroutes then gives you the option to save these plans in a number of formats. From FS2002, FS2004 (FS9), FSX, PMDG, Level D 767, FSinn and more. I always select FSX and save to my default FSX flight plan folder. These plans load perfectly in all my addon FMC's and default aircrafts GPS. But they wouldn't load in EFB. I did use the simple "trick you described above by loading into the FSX flight planner, saved it using the same name. It then does load in EFB but unfortunately now it isn't recognized by my EagleSoft Citation X FMC, my favorite aircraft. I haven't tried it with my other addon aircraft FMC's yet....will advise. However I assume I could choose my .PLN flight plan saved from simroutes, load it into the FSX flight planner and save it with a KBOS-KLGA_EFB.PLN name. Would that keep the original KBOS-KLGA_X.PLN for my Eaglesoft Citation X?
A little cumbersome but still faster than hand entering them all over again. Thanks for the tip next time I will spend more time reading through the forum before posting.
Regards
Bob
