Ok, a astute observation about autothrust...and of course it is on the L1011.
On this airplane, two channels of autothrust, with (as I recall, eight accelerometers )for each channel, both channels active during automatic approach/land (autoland) ops.
The autothrust system is very accurate, especially during windshear occurances.
Sometimes...you might see Vref+40 on appraoch, at 800agl, yet it unfailingly reduces to Vref +10, crossing the fence.

IE: the GOLD standard.
It will provide the proper thrust for all situations during approach....much better than any pilot could.
Even...411A.
Lockheed...simply built to a higher standard.
Over thirty years ago.

Ahhhh, Lockheed!!

PS: One of the reasons that the L1011 autothrust is so good...the airplane is powered by the three-shaft RollsRoyce RB.211 engine, with its superb acceleration qualities.
RollsRoyce...very good engines.
I kid you not.

PPS: The Conway was superb, as well.
Credit where credit is due.
