Runway safety related accidents, in particular runway excursions, remain aviation’s number one safety risk category. Among the top contributing factors are poor braking action due to contaminated runways combined with shortfalls in the accuracy of runway surface condition assessments and timeliness of communications on changing conditions. As a consequence, ICAO has developed a new methodology for assessing and reporting runway surface conditions commonly known as the Global Reporting Format (GRF), which has become applicable since 4 November 2021.
Accurate and up to date runway condition reporting is critical to reduce the risk of runway excursions. This information allows flight crews to make informed decisions on take-off and landing conditions. A standardized approach of reporting will ensure a common language between all stakeholders.
Preparation of all industry segments for the implementation of this change is critical.
GRF implementation: preparation for airports
GRF Implementation progress survey
ACI World has created a survey in order to better assess the progress of implementation of the new GRF methodology on a global scale. The information gathered in this survey will be kept confidential and only used in aggregate form to provide an industry overview. The results will also help ICAO and industry partners ensure a smooth transition to GRF.
