I've just committed at least one fix - the problem actually predates
my navradio change, but it also my fault. I broke the elevation data
for ILS/LOC navids when I cleaned up the 'align localiser with runway
centerline' logic. The problem is that runways don't have an elevation
specified (in apt.dat).
I've actually fixed this in two ways:
- alignLocaliserWithRunway uses the original, specified elevation for
the navid
- runways (and taxiways) are initialised with the airport elevation
instead of a zero elevation in the apt_loader. This is still a poor
substitute for correct values, but in the absence of source for the
actual runway elevation profile, it's much better than assuming zero.
