Besides flying the line in the -200 series from 1986-
1991, I taught the -100 series back in 1977-78.

After 1991, there was an FAA order to block out the 40 degree flap position
on 727s. It is because of balked landing performance with stuck flaps, not
because of noise limits. The quickest way to comply is to put a bolt behind
the 30 degree setting. Guess what happened to the bolt when we went into
4900' with 2% downslope and obstructed final approach?

Would you like a lesson on the flap/speedbrake interaction
and the sink rates that it causes?

How about roll rates with half speedbrakes?
