Re: Bad Data Input/High System Utilisation.
The problem is the quality of the Flight Plan messages.
Having had to develop software that understands the format of Flight Plan messages
(Think IATA Type B messages on steroids)
there are huge potential problems. My system regularly rejects 40% of FPL messages.
For example, the spec says that there MUST be a SPACE after the Aircraft Reg No. Many FPL's are submitted with this missing. Some messages use the IATA code for an destination when they must use the ICAO code.
eg Heathrow is IATA LHR, ICAO EGLL.
This is all despite most FPL's beging generated by software in the first place.
This is a disaster waiting to happen. It nearly did last week.
These events do not surprise me at all.
