It would be a trivial patch to genapts to always generate leading zeros,
however it appears that all US General Aviation airports don't use the
leading zero, US Military bases are mixed, and Europe uses leading
zeros. Looking thru apt.dat it appears all runway numbers have the
leading zero so we can't use that data to algorithmically determine the
format to use... So here's the patch to always generate leading zeros,
but should it be applied everywhere?
