As one of those very nice chaps who sit in the glass box, lording it over all that i survey, i have to say that turning your landing lights on for final approach would be a great help. Light a/c especially can be very hard to pick out against a backdrop of grey/white clouds, buildings (as you get lower) and can save us valuable time. It may also help the driver on the ground, who's lining up after you to spot you earlier.
Does that help?
Oh and don't forget to give us a wave now and then!!
