The phenomenon of artificial horizon acceleration errors was well-known by 1966 and it surprises me that Australian Vampires hadn't been retrofitted with modified versions by then. What with that and the 3-pointer altimeter, IF must have been
such fun in those days...
Quite how anyone accepted an aircraft into service with a cabin temperature/pressure selector the same shape as the elevator trim wheel, undercarriage and flap levers on the same (virtually hidden) quadrant box, dive brake lever next to the HP cock and the LP cock under the throttle, is beyond me. An ergonomic nightmare! Hunter T7 and Jet Provost were a lot safer in that regard.
de Havilland might have made pretty-looking aeroplanes, but cockpit ergonomics don't seem to have been their strongest suit.
