Thats the difference between ‘measured’ RCAM and BA reports. A braking action report from a transport category aircraft should carry more weight than RCAM.
RCAM is more for planning, and when actual reports aren’t available. When an A320 reports medium-poor and you have an event like this, the investigation won’t be kind if you attempt to fall back on the RCAM report.
I have never actually heard a tower controller report the RCAM to an aircraft along with a braking action report. These were, in essence, contradictory. I’m sure this will come up during any inquiry, and is hopefully addressed.
