De-crabbing with perfect centerline tracking into a 25 kt cross-wind?
Wow.
Didn't realize these big Boeing/Airbus autopilot systems were that accurate and responsive with the aileron and rudder manipulations during such a critical phase.
Not just new(er) designs.
L1011, max demonstrated cross 35knots...and I have personally landed (automatic approach/land) several times with this wind (gusting to a bit more) in visibilities of less than 600 meters, with precise centerline tracking.
Not bad for an old analogue design, that was the gold standard at one time.

And, just whom do we have to thank for these precise autopilots today?
The pioneers...Smiths and Hawker Siddley, with the Trident, as they did it first so very long ago.

Credit where credit is due.

And, not forgetting Caravelle, with it's Lear designed autoland system, although I personally don't know much about its development.
