Well, just ask the TriStar pilot...he (or she) can engage the autopilot on the ground (CWS) and then commence the takeoff....this is not possible with L1011 aeroplanes on the British register as the ARB (CAA) decided that this was not a good idea...which begs the question...what do they know about a US designed aeroplane....answers on a postcard.
Re-engineering the wheel comes to mind.
Minds stuck in the Trident mode.....
