Take off/Landing speeds

[SWAFO]

That's right. We love smooth landings (the PAX don't complain either), however if you touchdown at too shallow a rate of descent
(anything less than -50ft/min), you risk possibly not triggering the air/ground sensor. This obviously is not a good thing, and would mean
that many aircraft systems would work as they were still airborne, until the ground crew is able to reset this sensor. The most noticeable
problem would be that the spoilers would not automatically deploy on touchdown.

Southwest doesn't really have any strict limitations regarding descent rate at touchdown (as long as it doesn't damage the gear, or injure
the PAX, it's okay in their book), however as pilots an ideal landing would be in the -100 to -200 ft/min range. This is a hard enough
touchdown to definetly trigger the air/ground sensor, and have a noticeable sensation of landing, however at the same time it's a very soft
landing that the PAX (and crew) will walk away from happily.
