Many programs use ° ’ " as a coordinate format, but FS2020 uses * ’ " at PLN file.
Simbrief or etc: N37° 27’ 45.00",E126° 26’ 21.00",+000023.00
FS2020 pln: N37* 27’ 45.00",E126* 26’ 21.00",+000023.00
This causes problems reading the plan files each programs. When using pln file of Simbrief at FS2020, Turn on Notepad and change every coordinates format.(° → *)
I don’t know what is global standard coordinates format. But I hope All programs use same format for All Sim Pilot’s convenience and happiness.
