Example output for an LFST to EDDF .pln file saved in the sim:
LFST LUPE7H KISEK ETASA XINLA SUKON SPES1L EDDF
Why would someone need this ?
You can't currently copy a list of waypoints from within MSFS. This tool may help you export your planned route to SimBrief for example.
I hope you may find this useful ;)
