course General Subjects

Global Reporting Format (GRF)



  • This training is suitable for both winter and tropical runway surface conditions
  • The objective to give relevant, reliable information on the runway surface condition.
  • Explain the need for and fundamental requirements of the GRF for assessing and reporting runway conditions
  • Describe factors that require adjustment for braking and accelerating in order to account for runway conditions
  • A standardized method of reporting in relation to airplane performance data.
  • Improving the safety of airport operations.
  • Complete a Runway Condition Report (RCR) to assess the performance of a take-off and landing
  • Summarize the end-to-end process of assessing and reporting runway conditions

Global Reporting Format (GRF) is an online course to train flight crew in the new ICAO methodology for assessing and reporting runway surface conditions. GRF is intended to be the only reporting format for international aviation. It applies to all environments, from wintery to tropical landscapes.

The GRF aims to mitigate the risk of runway excursions, the most common form of runway safety-related incidents, through the harmonized assessment and reporting of runway surface conditions. Make sure you’re trained, prepared, and qualified before the 4th of November 2021.

The majority of runway excursions occur when the runway is contaminated by water, ice, or snow. At the moment, runway surface conditions may be reported using several types of different methodologies around the world, such as depth of runway contamination, airplane braking action, etc. 

This has created confusion and can cause misunderstandings between reports and flight crew. Accidents related to runway excursions are one of the top safety risks in aviation.

The International Civil Aviation Organization (ICAO) study in 2006, to understand the underlying reasons for this problem, resulted in interesting findings: different methodologies being used around the world for information sharing about runway conditions, different communications methods, lack of harmonization in reporting, different training and even lack of training.


What’s new: 

The new SNOWTAM format will now gain global acceptance which the old one did not. The new SNOWTAM will be built around “Assessment” instead of “Observation” with 2 sections:

  • Aeroplane performance Section.

  • Situational Awareness Section.

Some of the changes are:

  • Only one runway designator is inserted for each runway and always the lower number. 

  • The maximum validity of a SNOWTAM will be 8 hours (not 24 hours).

  • A new SNOWTAM shall be issued whenever a new runway condition report (RCR) is received.

  • A new SNOWTAM cancels the previous SNOWTAM.

  • The advantage of grooved runways
  • Runway Condition Assessment Matrix (RCAM) and the Runway Contamination Assessment Process
  • The effectiveness of braking decreases due to the presence of standing water
