A bit wide of the mark - I took the exams for a FISO licence in late '75 or early '76 and I think they'd been done this way for several years before. Maybe it's just that NATS people didn't have to do the exams - there were lots of differences between the way that NATS and 'non-State ATS' worked in those days.

An interesting document indeed - I've only given it a quick skim through but does anyone know what its status is?
