FleetBoards return data might be some problems?


#1

Hello,
i made a search with FleetBoards for a specific fleet code and the systems return some data which does seem to be correct or maybe i cannot find the docs about it.

departure_delay and arrival_delay are those seconds or something else?
In the faq they say that to define

  • How late the arrival was = (actualarrivaltime - (filed_departuretime + filed_ete)).
    And i think should be the same of arrival_delay…
    But they are always different please see below example (an extract of the json response)

Can anyone help me? Thank you.

The departure_delay and arrival_delay seen in FleetBoards is part of the FlightInfoStatusStruct. If using the API explorer it’s definition is visible under FlightInfoStatus.

departure_delay

Departure delay (in seconds) based on either actual or estimated gate departure time. If gate time is unavailable then based on runway departure time. A negative value indicates the flight is early.

arrival_delay

Arrival delay (in seconds) based on either actual or estimated gate arrival time. If gate time is unavailable then based on runway arrival time. A negative value indicates the flight is early.

Both are a difference between what was scheduled and what actually, or was estimated, to occur. The method in the FAQ is designed for the FlightInfoEx command, which does not expose gate times.
