Guys - and it seems most prominent in BA - I appreciate it's no doubt part of your runway / line-up checks but is there any chance you could hesitate for a second before switching your strobes on, particularly at dusk / night?
I've lost count of the number of times I've been blinded (quite literally whopping great white spots in my field of vision for the next few minutes) when I sit behind you in a queue for departure at LGW & your tail strobes burst in to life before you've even entered the active. PLEASE wait till you've turned the corner, if at all possible. And no, I'm not trying to infer a re-write of your SOPs.
