Wow ! What a lot of information . The CRFI replaced the JBI . Tribo seems to indicate that at JBI 25 and above relates to a good surface. The second table I produced seems to be the standard ICAO ( give or take ) .
When landing at YYZ not so long ago we were given friction coefficient .33 braking action fair which I would have expected given the ICAO table which seems to be in use in Scandanavia. I saw .61 in the weather for Goose the other day but I read in the Canadian AIP that reports are only given when the coefficient drops below .40
Is there any way of relating CRFI to ICAO friction index ?
