Maybe it is not that useful, but the data needed for the Missionsgerät and its map has found a new purpose:
Aerofly FS Airport Code Validator
This small tools allows for checking if an airport exists in Aerofly FS4. You need to supply an ICAO Code, and it will answer if this code is present in the current version of the sim.
The database (and datasets) behind this are kept up to date by a simple automatisation.
