I find this quote from the report interesting:
"CL-604 Operating Manual The manufacturer’s Operating Manual (OM) stated in ‘NORMAL PROCEDURES, Approach and Landing’ that VREF+X is calculated by adding a wind correction of ‘half steady state crosswind plus all gust (regardless of direction). Maximum correction is + 20 KIAS’ to the VREF. For the reported wind of from 300° at 13 kt gusting 25 kt, and a VREF of 123 kt, this equates to a VREF +X of 142 kt".
On most airliners, it has traditionally been half(or a third) the steady state headwind plus all of the gust.
Anybody seen this before on other aircraft?
