Flightdetent:
Very good point. My company charts state meaning for ICAO frictions and CIS frictions separately. However, for some time (3 years) is has been concluded that CIS had stopped using those and report standard ICAO values. Can we find a reference?
I got this information from the Lufthansa Lido Charts used in “my” company.
In the “country rules and regulations part” about the CIS I found this:
BRAKING ACTION (EXC KAZAKHSTAN)
Friction Coefficient Braking Conditions
0.42 and above GOOD
0.42 - 0.40 MEDIUM TO GOOD
0.39 - 0.37 MEDIUM
0.36 - 0.35 MEDIUM TO POOR
0.34 - 0.31 POOR
0.30 and below Unreliable
The table above shows the normative friction coefficient (Russian friction coefficient) as reported by authorities compared to the values derived from the ATT2 (equivalent to the SAAB friction tester).
The page with this information was last updated on 18 jan 2007. I got a report of braking action 34 over HF when I was 90 min out of Moscow. Moscow ATC later confirmed the braking action to be poor. So I guess Russia does indeed still use this different friction coefficient.
I was not impressed by the Moscow ATCO’s English language knowledge. I tried to get pilot reports of the braking action and tried to find out if the rwy would be cleared soon. They simply did not understand what I tried to ask! 15 min later they managed to inform me that my destination (DME) was closed and would “open three-five”.
My question if the airport would open at 35 past the hour or 35 mins later was not understood.
Anyway, I was glad I took a lot of extra fuel and arrived over DME with 160 min endurance in the tanks. It turned out I had to make only 1 orbit in the hold before being vectored (with a 90 ° intercept heading
) to the ILS.
