Position data on the stand
I was on holiday in Madeira the other week and passed some time on the balcony at the airport waiting for the delayed return flight, watching other holidaymakers being hurled skywards on their journeys home (and topping up the tan!). I noticed that each stand had the lat/long of that stand (to the nearest thousandth of a second) and other data painted alongside where the nose of the aircraft would be, easily visible from the cockpit.
I've never seen that before, despite having flown quite a lot over the last twenty years, mainly on business. Is it a common practice - and does it help speed up setting the IN which, I presume, is why it is there?
