You amaze me!! I worked with that system for well over 20 years and think it's God's Gift. Every airline pilot and controller I've spoken to also thinks it's fantastic.
Well HD, I too think it is a great system ..... but ...... 99.9% of the airports around the world work perfectly ok without it. I agree with Max Angle, it is useful in conditions of low vis, but TOTALLY unnecessary at all other times. You speak as an (ex) controller, not as a pilot. I speak as a pilot. At night, the time when the system is normally used, 99.9% of the time the vis is perfectly good enough to see all other aircraft, WE (the pilots) do not need the system, so why do YOU (controllers/BAA) require it. Please explain what the safety benefits are. Even in low vis ops, other airports do not have it, why does LHR, (LGW, STN, etc)?
