I certainly found there was a love/hate schism during my research. R.A.F. and B.O.A.C. pilots had an input into how it evolved, and how it relayed information. By and large, ex-R.A.F. pilots flying B.O.A.C. aircraft thought it was eminently logical and efficient, while pilots converting from other systems, for example Sperry, absolutely loathed it. That situation became worse as Comets, Britannias, Viscounts and Vanguards were taken up by other operators with a broader mix of people.
