Going back further, Gazelle AH1 SPIFR with no SAS and with Doppler mini-TANs in the BAOR IF Corridor...……….
Or going back further Whirlwind 10s with no AFCS, or trim: Let the stick go and it fell over and the aeroplane followed it. Even further back the Sycamore with no AFCS, no hydraulics and controls that were so heavy that there were wheel operated springs so you could control the the wooden rotor system. That was after you had pumped a water/glycol mix to or from the boom so it would stay within CofG limits.
You telling us you have to write an SOP to punch FMS buttons?????
