Canadian Braking Actions and Snowtams
 

Can anybody point me in the right direction?

I am trying to find out how to get hold of Canadian braking action figures which dont seem to be available on the published snowtams

Here is the CYYR one from today:

SNOWTAM
CYYR RSC 08/26 180FT CENTERLINE 90 PERCENT BARE AND DRY 10 PERCENT
DRY SNOW TRACE. REMAINDER 100 PERCENT COMPACT SNOW. 4 TO 8IN WINDROWS
10FT FM LGTS 0711141457
CYYR RSC 16/34 180FT CENTERLINE 90 PERCENT BARE AND DRY 10 PERCENT
DRY SNOW TRACE. REMAINDER 100 PERCENT DRY SNOW 1IN. 4IN WINDROWS 10FT
FM LGTS 0711141457

Your registered address. If wrong, PM correct one. (and change it!!!)

A 90% Bare/Dry runway with a trace of dry snow will not normally have a CRFI (Canadian Runway Friction Index) value measured as the runway average will equate to a Bare/Dry runway value of .8 or maximum braking. Such conditions would normally only have a runway surface condition reported in plain language.

See the Canadian AIM.
