I dowloaded VasFMC 2.1 which i think is the latest version. It doesnt seem to work i get the error message "could not open airport file ./navdata/airports.txt Make sure you have the navdata installed!"
how do I install the navigation data into the vasFMC installation directory? and where do i get it from? is it freeware?
My second question is what aircraft will this work on? default jets (i hope) or just PDMG stuff?
