I've never heard of the FAA having an opinion about that. The
technique probably has more to do with practicalities than regulations.


Brakes, thrust reversers, spoilers and other lift dump devices all help
airplanes stop.

On most jets these devices don't start working until the wheels hit the
ground. So getting wheels on the ground quickly works better. But
with excess runway hold-it-off greasers are possible and even
desireable in some cases.
