Yes, there are some inconsistancies with Robin's latest data ... many of these have been reported, hopefully he will clean these up and do a new db release soon.

Hi.  The new airport data has duplicate entries for a lot of airports.
It looks like in some cases, data for airports changed -- runways
got moved or rotated, new taxiways got added, etc. -- so an entire
new set of data for the airport went in, while the old one was still
listed.  There are some duplicates that look exactly the same --
perhaps they changed in something not listed in runways.dat, such as
their radio freqs.


This is not simply duplicate use of the "ZZ" identifiers, but actual full airports that are in there twice. I don't know whether duplication where the position is exactly the same is an issue. But there are places where things aren't the same in the layout. KMHT (see example below) is gonna look a mess with its old and new runway lengths and orientations, and two sets of taxiways superimposed and offset.

Just a heads up . . .
