Very simple, each airstrip is a wypt labelled with a 3 digit approach heading. Use it, or the reciprocal heading, to land at any strip in any visibility/wind condition, or die trying. --Easily change to your aircraft choice. Use this for simple freeflight, or add units/build a mission on it.
-Switchup the clouds/fog/time/wind often!
-Wypt 0 is my fav airstrip in the map, very interesting to approach, heavy :) from the south here.
-Wypt 7 & 13 are the shortest on this map fyi, have fun with various weight landings.
