ICAO/ACI Symposium on Implementation of the New Global Reporting Format for Runway Surface Condition aims at increasing international awareness in advance of the November 2020 applicability date of the new ICAO methodology for assessing and reporting runway surface conditions. This new methodology, commonly known as the Global Reporting Format (GRF), ensures a harmonized assessment and reporting of runway surface conditions and a correspondingly improved flight crew assessment of take-off and landing performance.
