Pace,
I am sure the CAA after reading your pearls of wisdom will change the regs and have all lighting removed off tall buildings like Canary Wharf???
I think I am saying that...though it sounds extreme initially. Can anyone on this board confirm that they or some reliable third party witness had taken evasive action on seeing lights on a tall structure? Out in the sticks where there are gliders and low-hours PLLs in dodgy VMC or night - radio masts, etc., then lights must be sensible. Near Canary Wharf? In any case it's hard to make out the statutory lights from the decorative lights. Seriously, has anyone here used lights while flying professionally for collision avoidance?
