The ICAO Global Reporting Format for runway surface conditions (GRF) mitigates the risk of runway excursions by enabling a harmonized assessment and reporting of runway surface conditions and an improved flight crew assessment of take-off and landing performance.
ICAO, in partnership with key international organisations, is providing support to Member States and industry as they progress their planning and implementation. In particular, training resources have been developed, awareness activities have taken place and additional guidance has been developed.
The applicability date for the GRF is 4 November 2021 (see State Letter 073e.pdf.), though, as we approach this date, some States and Regions have already implemented.
A complete set of ICAO SARPS and guidance is available through the respective content of:
- Annex 14: Aerodromes, Volume I, Aerodrome Design and Operations
- Annex 3: Meteorological Service for International Air Navigation
- Annex 6: Operation of Aircraft (Parts 1 and 2)
- Annex 8: Airworthiness of Aircraft
- Annex 15: Aeronautical Information Services
- PANS Aerodromes (Doc 9981)
- PANS-AIM (Doc 10066)
- PANS-ATM (Doc 4444).
In addition, supporting material is available in:
- Circular 355: Assessment, Measurement and Reporting of Runway Surface Conditions
- Doc 10064: Aeroplane Performance Manual

Awareness Symposium and Seminars
In 2019 and 2020 ICAO and its partners hosted a global GRF symposium, followed by a series of regional seminars, links to which are provided under the events link below. Due to the COVID crisis, this programme of physical events has been substituted by an on-going series of webinars, links to which are provided under webinar tab below.
