I wrote an article on Heathrow Parallel Landing Trials in a magazine dated December 1965. It wouldn't work then, when the movement rate was half what it is now, so why should it be any different now?
Without wanting to ramp up the angst.
Why can't Heathrow be like other modern airport and land on parallels?
I understand why you have gone the way you have; but with modern surveillance, PRMs etc. why can't you have independent approaches when the WX is good or the technology is available or dependant approaches when the WX isn't good or the technology isn't available?
