BOAC,
My thinking goes way, way, back to the days before the MCT. The southern hold at Manch was the Congleton NDB. There were 2 NDBs, the 'MCR', (in Knutsford 25nm range), and the 'ME', (in Edgeley, 15nm range).
The non-radar procedures at that time were CON-MCR-ME, (due to the ME's limited range). Although holds were published at all the beacons, no reversal procedure was ever mentioned in training. This was all in the days of 'clockwork instruments' of course.
A cunundrum indeed.
Can you remember the Kestral RNAV trial with BUSBY, TRAFA, MELLA and ETLEY? A precoursor of 'Point-Merge'?
