Flight Update Message
13
- ETA - FLTSTATE - (HoD) - (DoY)
- Format according to standards - Has ARCID, ADEP, ADES, DOF - Inbound EHAM - FPL in first message - Not CNL, DIV, AFL, (CHG,
ACH)
- Last received estimate - WRT ATA
AFTN Extract & filter
Determine ATA
Database
Determine prediction
errors Interpolate
Select common group
Calculate distribution
Store distribution sets
- To fixed ETA values
Determine FLTSTATE
- Use EDEXP FLTSTATE - If not available use DEP
