Who else uses them again?
Been a while since I've operated internatinally but I recall seeing the following airlines with wing lights on at various stages.
BA, Singair, Thai, Air France, Malaysian, Philippine Air Lines, Lufthansa, Cathay, Air China, China southern, China Eastern, Cathay (although that may have been a one off), etc, etc.
Please advise your management of the dangers to the rest of the aviation community, so you can get your SOP changed. It can be done.
Strewth, lucky you told us on PPRUNE that this is what we should have done. We would
never have thought of that on our own.
As noted by others, this is supposedly the 'norm' around the world and so the standard response is that we won't be changing it unless ICAO and the euro mob change their guidance.
It'll be another three or four weeks and we'll be doing this discussion all over again.
