Introduction of the new SNOWTAM format (GRF, Global Reporting Format)
Beginning from 12 August 12 the new Global Reporting Format will come into effect along with the rules connected to the new SNOWTAM format. We have published a new AIC in the topic numbered AIC A 003/2021, available on the AIP page.
Requesting a new SNOWTAM in the PLX system will already offer the renewed GRF to be filled out.
More information on this topic can be found on EASA's website:
