The New Global Reporting Format for Runway Surface Conditions


The 5 November 2020 applicability date for the GRF is fast approaching, so in partnership with key international organisations ICAO is working hard to support its Member States and stakeholders as they start their planning. To help, an important awareness action took place during the ICAO Assembly's 40th session, with a GRF-related Skytalk.






The new ICAO methodology for assessing and reporting runway surface conditions, commonly known as the Global Reporting Format (GRF), enables the harmonized assessment and reporting of runway surface conditions and a correspondingly improved flight crew assessment of take-off and landing performance.

The GRF, applicable on 5 November 2020, is described through amendment 13-B to Annex 14 — Aerodromes, Volume I — Aerodrome Design and Operations; Annex 3 — Meteorological Service for International Air Navigation; Annex 6 — Operation of Aircraft, Part I — International Commercial Air Transport — Aeroplanes and Part IIInternational General Aviation Aeroplanes; Annex 8 — Airworthiness of Aircraft; Annex 15 — Aeronautical Information Services and Procedures for Air Navigation Services (PANS) — Aerodromes (PANS-Aerodromes, Doc 9981), Aeronautical Information Management (PANS-AIM, Doc 10066) and Air Traffic Management (PANS-ATM, Doc 4444).

In addition, supporting material is available in Circular 355, Assessment, Measurement and Reporting of Runway Surface Conditions and in the Doc 10064 Aeroplane Performance Manual (in preparation).

All of the above reference documents are available through the ICAO publications portal.

Various activities are being conducted to raise awareness and support deployment of the GRF such as a global symposium and regional seminars that will take place between June 2019 and November 2020.
