In response to the on-going COVID-19 pandemic and the associated challenges facing the aviation industry, ICAO has delayed the applicability date of the GRF until 4 November 2021 (see State Letter 073e.pdf.).
ICAO, in partnership with key international organisations will continue to provide support to Member States and stakeholders as they emerge from the current crisis and revise their implementation plans. In particular, training resources will be enhanced and awareness raising activities will be re-launched.
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 4 November 2021, 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 II —
International 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.
For more information and presentations,
Relevant courses are being developed with ICAO partners, under the Global Aviation Training (GAT) and TRAINAIR PLUS Programme:
Note: Other courses for other stakeholders are under development and will be added in due course.
Stemming from the regional seminars, a generic GRF Implementation check list for States has been proposed by some States and is available here:

Implementation experience has shown that some additional guidance may be required, addressing specific aspects of the GRF:
