I’m aware it’s a matter of taste. I’m aware that some didn’t like it and prefer the Douglas Dc-10 Series,
but overall, the L-1011 was an extraordinary appearance. Let’s find out what Lockheed Martin has to say about it.
In April 1972, after six grueling years of design and some unforeseen setbacks,
the then-Lockheed California Company (now Lockheed Martin) delivered the most technologically advanced commercial jet of its era, the L-1011 TriStar, to its first client,
Eastern Airlines.
Worth to highlight since the Lockheed Tristar L-1011 was a very sophisticated aircraft in those days.
Check out this “the L-1011 featured a highly advanced autopilot system and was the first widebody to receive FAA certification for Cat-IIIc autolanding,
which approved the TriStar for completely blind landings in zero-visibility weather performed by the aircraft’s autopilot.
The L-1011 used an inertial navigation system to navigate; this included aligning the navigation system by entering current coordinates of longitude and latitude.
It also had a unique direct lift control (DLC) system, which allowed for smooth approaches when landing, without having to use significant pitch changes while on the approach path.
DLC helps maintain the aircraft on the glideslope during final approach by automatically deploying spoiler panels on the wings.
Thus, rather than maintaining the descent by adjusting pitch, DLC helps control the descent while maintaining a more consistent pitch angle, using four redundant hydraulic systems.
Production also used a unique “autoclave” system for bonding fuselage panels together; this made the L-1011 extremely resistant to corrosion.”
