Re Fuel Tankering

IIRC the figure of 3 to 4 tonnes extra was quoted (a long way back). From the QRH increase in Vapp is 1 kt per tonne, and on a Wet runway an extra 75 m (approx) increase in actual landing distance would result for 4 tonnes extra. The figure for a 6.3 mm (1/4 inch) of Water runway is approx 118 m extra.
Hard to know at this distance whether the skipper took extra for weather or fuel policy .. if the latter he might still have taken an extra something for wx or other local factors.
