Well raven flight, coming from FRA you certainly are close to the headquarters of Lido. Would be quite intersted to find out more about the "Mercedes", since I have only heard few real facts about the system, as yet. The one thing I heard from Lido (which I don`t know, whether it`s true, but which would certainly prove to be a disadvantge), would be that the route database structure is relying on hardcoded, canned routes. If that is the case than this system would lack much of its dispatch flexibility (once more I am not absotlutely positive that I am right).
