I also do not believe that ATC refused a grip test. As Gonzo states, the mid portion of 27L has been contaminated by rubber deposits and in wet conditions the braking coefficient ranges from 0.33 to 0.54. This equates to medium braking action. Instead of a vague "slippery when wet," which I believe leads to some airlines using performance calculations for icy runways, the Airport Authority should measure the exact braking action with a grip tester and publish this information, even if it results in a loss of a runway for 15 minutes.
Snooky, please clarify the crosswind limitations for B757/B767 aircraft - under what conditions does the 10kt limit apply?
Hopefully all will be resolved when they resurface 09R/27L next year!
