Why 1.3 Vs for approach?
Why 1.3 not 1.2/1.5/1.1 etc?
Is this a value arrived at by experience or is there some objective reason why 1.3 was chosen?
Is this valid across most aircraft types and if not is there a reason why not?
Does this include an element of gust protection or does that have to be added separately?
(I'm particularly interested as to how it effects the light end of the aviation spectrum.)
