Despite the challenges brought about by the current crisis, runway safety remains one of ICAO’s top priorities. Although there has been a severe reduction in air traffic, runway incursions and excursions continue to occur. Some risks might even have even increased due to changes in runway and taxiway utilization, different surface traffic patterns and more ‘continuous descent’ approaches.
As we begin to emerge from the crisis, aviation needs to rebuild confidence both in itself as well as amongst the travelling public. Though the main challenges are directly associated with the COVID virus, such as quarantine regulations, ensuring the safety of aircraft operations, including runway safety, remains an important cornerstone of our industry. It, therefore, contributes to this much-needed confidence.
The Global Reporting Format (GRF) for assessing and reporting runway surface conditions has been developed by ICAO to mitigate the risk of runway excursions, the most common form of runway safety-related incident, through the harmonized observation and reporting of runway surface conditions. It comprises the assessment of runway surface conditions by a trained observer (normally airport operations staff) who, using a globally recognized runway condition matrix, allocates a runway condition code to each third of a runway. This code is complemented by a description of the surface contaminant, including its type, depth and amount of coverage, again per third and using a globally recognized set of descriptors. The outcome of the evaluation is then incorporated into a standard report, the Runway Condition Report (RCR), which is then forwarded to the air traffic and aeronautical information services for transmission to pilots by SNOWTAM, by ATIS and if necessary also by radio broadcast.
By correlating the RCR with aircraft performance data provided by the manufacturer, the flight crew is then able to calculate their takeoff or landing performance. This matching of standardized observation and reporting with standardized aircraft data is the key advantage of the GRF. Another important element of the GRF is the facility for flight crew to provide their own observations of runway surface conditions, used to confirm the RWYCC or provide an alert to changing conditions. It should also be noted that the GRF does not only apply to winter snow and ice conditions, it also applies to wet runways.
Until recently ICAO, with its Member States and the industry, had been working towards an applicability date of 5 November 2020. Awareness seminars and workshops have taken place in all ICAO regions, training courses for flight crew, airports operations, ATC and AIS staff have been developed or are under development. However, to alleviate the burden on Member States during, and in the aftermath of the COVID-19 pandemic, the ICAO Council issued a State Letter (SL 2020/073) postponing the applicability date until 4 November 2021. This delay reflects the importance of this runway safety related implementation and the need for a harmonized approach by affording everyone involved the opportunity to better prepare, even during these difficult times.
ICAO, in partnership with States and industry, is now working towards the new date. Efforts to improve awareness and support preparations for implementation are being ramped-up, with the further development of training resources, the publishing additional guidance and the hosting webinars etc.
It is the intention that, as far as possible, the GRF be implemented simultaneously around the globe on 4 November 2021. For this to happen preparations need to be made to ensure that airport operations, flight crew, ATC and AIS staff know about the GRF, that they are adequately trained, competent and ready for this important change. Accordingly, States should now appoint a focal point who should work with regulators, airports airlines, and service providers etc. to raise awareness and develop a State implementation plan.
