Hi GaryGnu,
I think EASA says that rev COULD be used for landing calculation on wet and contaminated rwy. (not must). For sure AIB used them for landing performance tables.
If you ck on new landing distance you have to subtract from landing distance reverse coefficient (it means, in my idea, you could land also without max reverse application and your landing distance will be longer).
I don't know what will happen in noise sensitive airports when soon half of the landing plane,in wet condition, will be with full reverse. (i don't know boeing procedure).
I don't think some chief pilots will publish something against airbus policy!
