I think the union has a great point, every major airport I have flown into around the world would have a runway condition report attached to an ATIS in these conditions with breakdowns of braking action and contamination. ZQN manages one with snow and ice but out main international airport can’t. You can’t judge water depth from an approach and ‘WET’ would tell you standing water of less than 3mm. Remember the Air France that went off the runway in Toronto? There were many factors but one of the findings was a contributing factor that contamination information wasn’t passed to the pilots and the airport would never ‘close’ the runway as it was up to the pilots….. bit hard to make an informed decision when the ATIF just says ‘wet!’
