Lou,
 Ok thanx for the reply....I know how to use that AP as I have used it many times in the 727-100(FSX) v2.2 basic.  the problem I have now is that when I upgrade to v2.4 in both the 727-100 and the 727-200 expansion pack, it works fine during climb out to when I level.
 After I level and wish to climb or descend, I switch off alt hold and click on the pitch/turn controller to est a des or clm.  I get no response from the aircraft and wind up using the trim on the yoke. Now i know there is the stab cruise trim which offers fine adjustments but it is a pain to keep bouncing back and forth on or to open another window on the screen.
 I would definitely prefer to use the pitch/turn controller instead

thanx
Ed
