Proposed by Istanbul Airport, the objective of this project is to establish a real-time communication of the delay reasons.
In 2021 the average departure delay (against the scheduled time) was 9.2mins/flight with ATFM delays contributing 0.8mins/flight. The length of delays is already shared in real-time through the EUROCONTROL MIRROR and NORTI portals but apart from ATFM delays (9% of total delay) there is no real-time sharing of the reasons for delay.
If delayed, flights are more likely to have been affected by non-ATFM delays (e.g. baggage loading, security checks, late fuelling, de-icing, etc.) with little real-time visibility to airport operators, ANSPs and the EUROCONTROL Network Manager on the reasons for these delays. Having a real-time insight into the delay reasons improves the situational awareness across the different actors and allows them to react during the operational day. The real-time sharing of the delay information in a centralised manner would allow for the tactical management of staff and resources adjusted to the actual operational situation. This allows early identification of disruptions at outstations potentially impacting the operation and at the same time centralises the collection of delay reasons to be used for post-ops performance analysis.
IATA has released a new delay code schema (AHM732) in 2022 composed of three digits representing the Turnaround Process, Reason and Stakeholder causing a delay. Sharing the IATA AHM732 Process layer information in real-time amongst operational stakeholders will provide the required insight in the delay drivers. The Process layer information does not disclose airline sensitive delay reasons or information on stakeholders.
