Thanks Don...much better to use airbus figures than to try and massage, and draw conclusions from, my 767 figures.
Lets assume for simplicity sake that the increased LDR is linear between nill wind and -10kts (tailwind)
From your figures that gives 6150' [(2063m+1664m)/2 (3.3)] unfactored (all reversers working). Close enough to the figure quoted earlier in the thread (6600') for govt workers.
6150 x 1.67 = 10270'
Lets assume nil wind...fighting hard to give the crew the benefit of all doubt.
1664m x 3.3 = 5490' x 1.67 = 9170'
Of course in my last post the 11000' figure (6614x 1.67) was correct and I should not have increased that figure anymore because the basic figure is already for 'poor' braking action thus requires no further factoring after 1.67. Post edited accordingly.
They still had no legal basis for starting an approach.
