Mixx,
I truly recognize the problem of aircraft not going to the runway
to which the mission builder intends. I have encountered this issue
myself on many occasions. There is a simple work around for this problem
though! When setting a way point for takeoff or landing, leave it set as
norm fly at first. Then change it to takeoff or landing and it will jump to the
nearest runway icon automatically. This locks that way point to that runway.
Conversely, when I am building an airfield, and I try to test a runway by
assigning aircraft to it, and I cannot get a way point to jump to a runway icon
then I know there is a problem with the design of the runway.
When I can I will follow the standard of aligning the runways to a
horizontal or vertical line. When in the cases when I cannot, you must know
that these runways have been thoroughly tested using the method
outlined above and they will work.
