Forgive me for being reminded of this by the pilot vs. computers controversy.
Once upon a time.....
In the earliest days of autoland....
The Americans wanted to keep the pilot in the loop. Basic autopilot, but a maximum of aids to the pilot to keep situational awareness, etc. - anybody here remembers Microvision?
Some Brits went for triplex redundancy (Trident), others for duplex-monitored systems (VC-10, Concorde): "keep your clammy hands off the controls, please, unless the "LAND" capability light goes out".
The irony is, that Sud went for the American philosophy with their trials of the Lear system on the Caravelle. Now that Sud has become Airbus, they've certainly did a 180° turn, what?
