ICAO’s standardized runway reporting format has now become applicable
5 November 2021

The ICAO Global Reporting Format (GRF) for assessing and reporting runway surface conditions, became applicable worldwide on 4 November 2021.
This harmonization of the assessment and reporting of runway surface conditions is intended to mitigate the risk of runway excursions, which continues to be the most common form of aviation accidents.
It will also benefit efficiency and sustainability, through a better planning of contaminant removal and the more effective use of de-icing and other treatments.

The GRF comprises a number of elements:

  • A harmonized matrix through which a trained observer allocates runway condition codes and descriptors;
  • A Runway Condition Report (RCR) containing the above information, which is transmitted to flight crew;
  • The flight crew’s correlation of the RCR with aircraft performance data, enabling them to calculate their take-off or landing performance; and
  • A facility for flight crew to provide observations of runway surface conditions.

ICAO reports that the implementation of the GRF is still on-going in many States.
