EDTO
Hai Guys,
Period of ValidityFor each EDTO en-route alternate airport, the Dispatch Weather Minima must be ensured within a certain period. This period starts one hour before the earliest ETA at this airport and ends one hour after the latest ETA. The following example will explain the usage of period of validity.
Start time at X
Departure time + EET to EEP X + Diversion EET (one engine cruise from EEP DPS to X) – One Hour.
End time at X
Departure time + EET to ETP1 + Diversion EET (one engine cruise from ETP1 to X) + one hour.
Start time at Y:
Departure time + EET to ETP1 + Diversion EET (one engine cruise from ETP1 to Y) – one hour.
End time at Y
Departure time + EET to EXP Y + Diversion EET (one engine cruise from EXP Y to Y) + one hour
how to elaborate this and give me some examples pls. Thank you
