In the '80s the SHAR had an internal aids let-down that worked very well; lock mother with the cloth co*k, enter the flying course and select PIA (pilot interpreted approach); the HUD then gave centreline and glidepath together with cues for hover-stop and braking-stop to get you alongside in the hover. Only snag was flying a very unstable jet at 140kts with 60 nozzles. I forget what the official limits were but it was proven down to 200' on occaisions, when flying non-div. Sorted the men etc!
Off to practise my turn-backs.
