I know some airlines do not allow there pilots to use 40 degree of flaps as it is said to be too much. That is why on all the modern airliners they only have 30. Do you guys know of any airlines that have inserted a bar across the flap control so there is no way you can get the 40 degree? And jetpilot what are the rules with US air?

At CO our B727's do have the block at the 40' mark.
However it could be removed for an emergency.
40 degrees can give the airplane a higher landing
weight and a lower approach speed,shorter landing
distance; but higher fuel useage, and with noise
rules, way to many decibels to be allowed. Most
domestic airlines that I know of, I belive operate
that same way for those reasons.
