Yesterday, I was looking at a video of an A380 landing at LAX on youtube. People was talking about how an A380 has a slower landing speed than a 747 or A340, and that got me to thinking. What 1970s era widebody has the slowest landing speed? If you can please list all four the 747, DC10, L1011 and A300 landing speed that would be nice? Thank you.

747 I think. At least it was well known for low landing speeds.

It's really too variable to answer definitively, because landing speed depends so much on the weight of the aircraft. The DC-10 or L1011 probably had the lower landing speed, depending on which one had the lowest possible 'legal inflight weight', meaning whichever one of those two could be emptied out the most and still be legal to fly. For instance (according to my somewhat-old DC-10 manual) Ref speed for landing at maximum landing weight and max flaps is about 137 knots, while at extremely light weights (no pax or cargo, minimum fuel) it could be as low as 115 knots. For comparison the 767 ranges from 145 knots at max landing weight to 119 knots for an empty aircraft. Those low-weight speed are somewhat unrealistic though, because nobody ever flew the planes regularly in that condition. I wasn't working at Hawaiian when we had the L1011's, so I don't have access to the numbers for that plane. Sorry.

One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.
