I just checked a patch into cvs. Feel free to give it a try and see
if it works any better ...
Note that there is a default airport (KSFO) and default runway (28L)
in the preferences file. So if you specify a different airport that
happens to have a 28L, that will probably take precidence over any
--heading= you might specify. This means that specifying a --heading=
around SFO won't work since the runway number takes precidence.
