Some time ago I created my own program to bulk generate flight information (for VABase) - and have been thinking about doing the same for phpVMS - to work out for a given aircraft on a given direct route, how long it would take - which can then be used to auto-populate scheduled flights in one go (e.g. with 5 airlines, 10 fleet groups,100 aircraft, and 50 airports around the world, generate the thousands of sensible looking flights taking off and landing within sensible hours, with fairly accurate time calculations based on aircraft performance.
I just wondered if anybody else has done this - to save re-inventing the wheel.
