Fireflybob,
Yes, that's correct but I cannot remember when this was withdrawn at LHR - I seem to recall it was still there in the early '80s. All PARs, as opposed to monitored ILS, were also hand flown, so I have a question for the modern high tech operator:
How would you fly a PAR if that was the only option? How late in the approach can you (i.e. what are the limitations on the equipment) continue on autopilot/autothrottle when not coupled to an ILS? Given that your FD will not have any electronic centreline or glideslope inputs, can you still accept the minimum of 550 RVR? Not a trick question just a request for information.
