Winter should not be seen as looming, it does in fact provide some of the best flying conditions of the year.
I have flown several winters up here in Scotland, most of the obvious traps have been covered already. I always take a plb, strobe, chocolate, mobile phone and waterproofs/warm clothing as a minimum.
I also try and fly around lunchtime to get the best of the high sun, theres nothing like the low winter sun and afternoon haze to lower your vis to uncomfortable levels.
I look forward to high pressure and gin clear winter days more than the hot and hazy days of summer.
