"Unfortunately the wind is rarely down 09/27 at LSI, and during the winter is often out of the 35 knot crosswind limit of the SAAB. Hence the constant use of 15/33. Now, It would be interesting to see what a Q400 could lift on those runways, especially when wet!"
15/33 similar in length to Guernsey, and entirely possible to lift at max weight (29t) with zero headwind component. A wet V1 unlikely to have a significantly adverse effect upon this weight. With a 15kt headwind, the Q400 can even perform a full flex, reduced power take off at 27t.
