So, ATC clear you to A1. Your pass A3, A2 (which is the CATlll hold) and you approach A1.
You are confronted by - 2 yellow lines and 2 dashed yelow lines across the TWY, a pair of wig wags and yellow/black and red signs telling you "A1 CATl" 27 - 09.
WHAT MORE DO YOU WANT?
If it's dark, then the reds will be on and the greens will stop. (UK SOP)
If it needs a painted marking on the ground to say there is a runway somewhere up front then, I put it to m'lud, that sumat else is up and a sticking plaster won't work long term.
I was at a pilot meeting recently and a chap from the states put it succinctly "you don't run reds coming to work in your automobile, so why the f88k do you do it in an airplane?!
I've seen a few of these markings around and whilst the intention is clearly to enhance safety, I think a point is being missed.
