We have added a new field EET - Estimated Endroute Time - in the Flight Watch.
The logic behind adding that field is that the values T/O + EET should always give ETA (which should be filled in automatically).
A flight ABC STD-08:00 PRG - ATH STA-10:20
T/O - 08:10 EET - 02:10 (the value input here should be the estimated lenght of the route) ETA - 10:30
If inserted ETA differs to T/O + EET Leon will show a warning:
You can also fill in ETA and Leon will calculate EET automatically.
