Just in case any newcomers to the profession are in any doubt ref airframe contamination:. .1. If there is ANY contamination whatsoever on the upper surface of the wings it MUST be removed. Do not depend upon snow blowing off. Snow may drop into gap between tailplane and elevator and cause restriction of movement esp if curtained.. .2. If the holdover time of the de-icer is insufficient then DEMAND appropriate anticing. If not available request hotel rooms for pax & crew hinting that airline will sue airport authority for cost thereoff. <img src="wink.gif" border="0"> . .3. Frost from cold-soaked wings is not acceptable on upper surface. Unfortunately, this may occur when tankering fuel into airports which rarely suffer from snow/ice and therefore have no de-icing equipment. Try (before re-fuelling) pumping wing fuel into centre tank and then re-fuel wings with warm fuel or run booster pumps to warm-up fuel; bit of a long process with several tonnes of paraffin at -10 deg on board.. .4. Finally - don't let tw^t climb up and try to warm up six tonnes of fuel by chucking bucket of hot water over wing! <img src="mad.gif" border="0">
