The L1011 did not need an FMS to provide fail/operational automatic approach/land (autoland) operations...it had the first dual/dual autopilot/flight director system (produced by Collins Radio) fitted to a wide body jet transport aircraft.
Yes, roll and pitch computers provided, straight out of the factory, from day one.
The FMS (manufactured by Hamilton Sundstrand) was added just slightly later on, to provide complete LNAV/VNAV and engine thrust management, in one neat (dual) package.
Those aircraft delivered to SVA had a moving map navigation display provided, as a standard fit.
The type is unsurpassed to this day in providing a very smooth operation during automatic approach/land maneuvers.
In short, it is the gold standard, to which others are compared.
Just ask the folks whom have flown this quite remarkable airplane.
Old?
Yes.
Superb?
Absolutely.
And, on the TriStar...it was all analogue.
Lockheed, simply designed and built to a higher standard....with proper RollsRoyce engines
