we need landing performance too all we got is take off try to complete this aircraft make just like Qualtywings same as FMC try to follow the steps too.
try to get the calculations right. calculate aircraft performance - time/speed/distance/course/fuel/wind. Try to Test it first do not release it yet first
See how it work for you, ONCE It works out pretty good then ever was before same as Qualtywings then release and make everyone happy so they don't
get very disappointed, I am not even flying my magknight so I am just being patient till everything works well as Realistic as it gets. The
