The header of a turnaround shows the key times of the arrival flight, of the aircraft, and of the departure flight. Here is what each acronym means. On mobile, slide the header from right to left to move from the arrival times to the departure times.
Arrival flight (left-hand side)
STA, Scheduled Time of Arrival: the arrival time planned according to the IATA seasonal schedule.
RTA, Rescheduled Time of Arrival: the arrival time updated by SSIM (Standard Schedules Information Manual).
ETA, Estimated Time of Arrival: the arrival time filled in automatically by an integration. It is sent once the aircraft is airborne from its origin.
ATA, Actual Time of Arrival: the exact moment the aircraft comes to a complete stop at the parking stand. It is also called AIBT (Actual In-Block Time).
ADO, Any Door Opened: the time the first aircraft door is opened.
Aircraft details (middle)
MTT, Minimum Turnaround Time: the shortest time, between block-in time and block-off time, needed to turn the aircraft around. It depends on the aircraft type (narrow-body or wide-body) and on other factors, such as the airport configuration (remote or contact stands) or the type of operation (hub or outstation).
Departure flight (right-hand side)
STD, Scheduled Time of Departure: the departure time planned according to the IATA seasonal schedule.
RTD, Rescheduled Time of Departure: the departure time updated by SSIM (Standard Schedules Information Manual). See What is RTD in AGOA?
PTD, Projected Time of Departure: the departure time calculated by AGOA when the inbound aircraft arrives late (LIAC).
ADCT, All Doors Closed Target: the time by which the last aircraft door must be closed to depart on time.
ADC, All Doors Closed: the time the last aircraft door was closed.
ATD, Actual Time of Departure: the time the aircraft leaves the parking stand. It is also called AOBT (Actual Off-Block Time).
How is the PTD calculated?
When an aircraft arrives late, AGOA calculates the Projected Time of Departure (PTD) as follows: ATA + MTT = PTD.
Not every late arrival results in a PTD. AGOA releases the PTD in AGOA Station only if both conditions are met:
ATA > STA (the aircraft arrives later than scheduled).
ATA + MTT > STD (the aircraft cannot depart on time).
Once both conditions are met, the PTD is released and AGOA shifts the cutoff times of the tasks to match this new departure time.
A preliminary PTD can also be issued based on the ETA of the arrival flight. Using the same two conditions, the PTD is updated or removed once the ATA (block-in time) is filled in AGOA.
Can I change the times contained in the header of the turnaround?
STA (Scheduled Time of Arrival) and STD (Scheduled Time of Departure) are filled in automatically in AGOA, and users cannot edit them in AGOA Station. If the flight has been rescheduled, use the RTA and RTD instead: see What is RTD in AGOA? If the scheduled time itself is wrong, send a message to [email protected].
ETA is either empty or filled in automatically. AGOA Station users cannot edit it. If it's missing or wrong, see Why is the ETA missing or wrong on my flight?
RTA and RTD are the times to use when a flight is rescheduled. You can edit them, but only when the airline or your manager explicitly tells you to.
PTD is either empty or calculated automatically. AGOA Station users cannot edit it. It is set up in the Backoffice by your AGOA administrator.
ADCT is the doors closure target. It is calculated from the departure time reference (STD, RTD, or PTD) minus an adjustment time set in the Backoffice by your AGOA administrator. AGOA Station users cannot change it.
ATA, ADO, ADC and ATD can be edited by AGOA Station users. First check whether they are filled in automatically or entered manually: automatic values take priority over manual input.
