Re “23R wet with deicing fluid”
Does the message refer to runway deicing fluid, which should have known friction characteristics, or is it a warning that aircraft de icing fluid has been shed on the runway which could significantly decrease the friction at the ‘stop’ end?
If the former, and the friction approximates to wet, then how much ‘wet’; the friction equivalent of 2.9 mm of water may not be contaminated, but it does not contribute to good stopping performance.
Furthermore, as above, what are the characteristics of any fluid on top of rubber (runway slippery when wet?), and what are the characteristics of aircraft de icing fluid on top of runway de icing fluid, IIRC they are not the same chemically.
