RTD (Rescheduled Time of Departure) is the new official departure time of a flight, set when a significant disruption formally reschedules it. It is shown in the header of the departure flight, next to the STD (Scheduled Time of Departure) and the PTD (Projected Time of Departure). For the other times of the header, see What do STA, ETA, STD, etc. stand for on AGOA? STA and STD can't be edited in AGOA Station, so a schedule change is reflected in the RTD and RTA.
Unlike the PTD, which AGOA calculates when the inbound aircraft arrives late, an RTD is a formal change of the flight schedule requested by the airline. It is not an estimate.
When is an RTD used?
An RTD is usually issued before the scheduled departure time, when a significant operational disruption requires the airline to reorganize its schedule. For example:
Aircraft on Ground (AOG)
Severe weather conditions
Fleet constraints
Other major operational disruptions
Once an RTD is issued, it becomes the new official departure time, and operational activities are adjusted accordingly.
How is the RTD updated in AGOA?
In most cases, the RTD is updated automatically in AGOA by SSIM (Standard Schedules Information Manual), through the airline's flight scheduling system (FMS).
What is the link between RTD and RTA?
When an RTD is updated, the corresponding arrival time should also be updated as the RTA (Rescheduled Time of Arrival). Likewise, if the RTA is modified, the RTD may also need adjusting to keep the flight schedule consistent.
Can I edit the RTD or the RTA?
RTD and RTA can be edited, but only change them when the airline or your manager explicitly tells you to. Incorrect values can affect operational activities, reporting, statistics, and analytical data in AGOA.
What should I do if the RTD is incorrect?
If the RTD shown in AGOA is incorrect, first check with the airline or your manager. Then use the Reset option: it sets the RTD back to zero. The same applies to the RTA.
Why does the incorrect RTD or RTA come back after a Reset?
If the incorrect value comes back after a Reset, it comes directly from the airline's flight scheduling system (FMS). AGOA keeps receiving it until it is corrected in the FMS.
Ask the airline's OCC (operations control centre) to correct the value directly in the FMS. It will automatically reflect on AGOA after the next call of the FMS by AGOA.
If the OCC can't correct it in the FMS, wait until the end of the period during which AGOA calls the FMS. The automatic updates then stop. This period usually ends at STD + 24 hours.
After that, you can edit the RTD or the RTA freely: the FMS no longer overwrites it with the incorrect value.
