Seeing several comments about 115% LDR: The factor for wet runways for dispatch is 1.92, (FAA and EASA). Correct me if I am wrong, but the 1.15 factor is only for in-flight calculations, and emergencies, is it not ?

I don't have access to a Boeing landing distance calculator - is a wet Leeds runway with significant crosswind and a 1.92 factor long enough for a 738 dispatch ?

Perhaps with somewhere like Leeds, EGNM, where you have:-

Out of wind runway, leading to significant crosswinds, AND

Significantly humped runway surface, AND

Challenging turbulent wind conditions common on approach. AND

High, exposed position, subject to more common and more intense adverse weather conditions, AND

A non grooved runway surface,

........Then perhaps a factor larger than 1.15 should be mandated ? (Especially when the visibility is also close to the limits.)


I operated into Leeds in Bombardier Dash-8s, back in the day. Plenty of ALD for those smaller craft, but it was usually very erm........exciting, even so !!
