Mmmm.....I see a niche in the market here - taxy-through food to go...that'll be 2 Waltham burgers and large fries, and a couple of bags of biltong for later. Anybody know the CAA's position on after-market cup-holders for a Yak?
Seriously - in the PA28s I generally have a bottle of water and a snack bar in the flight bag close to hand.
