Yes, the -200; oh dear.

A/T design stagnated (excuse the pun) on the 47 due to the fact that at the other end of the A/T switch(es) is an engine(s).

Throttle bar on the 47-100 with the early Pratts, 'sub idle' requiring a minimum level of thrust during descent (RR eng/ -200) and a couple of other problems both, those well known and those not so well known, contributed to the argument that with engines requiring tlc, there was no need for massive development of the A/T system.

As Joe Sutter, the father of the 47, pointed out, the only reason the A/T eventually was further developed was at the insistence of the TPs who wanted those functions to reduce crew workload during extended cruise etc.

Limited flying of a DC8 (-63) but it seemed to have had better control harmony and more acceptable stick forces compared to the 707. I soon realised with the 07 why it was known at the time as 'the airborne bullworker', named after a then popular isometric exercise device as you most probably also recall.
