I recall that ILS's were categorized depending on their accuracy. Cat1 to3C. Is it still the same?
A displaced ILS would have a higher minimum and 3C permitted autoland i.e. zero visibility.
I've been on board many autolands in practice and a few in earnest...I think Gatwick, or was it Heathrow, have autoland 3C.
The Autopilot does the flare and the auto-throttles control the thrust. The crews duty was to disengege and reverse and keep on the centre line.
Once I was a guest on a Belfast at RAF Brize Norton which I think used a leader cable system...it maintained the centre line with a roll-out mechanism of swirling horizontal mini-barbers poles which rotated at different speeds, showing which way to manouevre.
Anyone remember that system and how it worked?
