Used it for many years - a really good system with no faults as far as I can see. Please leave well alone.
If British Bl@@dy Airways wants it changed, kindly inform them that they don't own the airfield, they are merely users and must abide by the same set of rules that govern everybody else.
I would be willing to bet that, should the system not be installed, one of their bright sparks would have seen it in operation in Singapore and there would be a great cry of " We want it here", from the same source.
LEAVE IT ALONE, please.
