4500 hours in the right seat... The 80 flies with "control tabs"... i.e. you move the wheel left, the control tab on the aileron actually moves down which moves the whole aileron up. Same with the elevators. So at slow speeds it gets kind of sloppy.
If you have to remember ANYTHING, remember this: During approach, if you have more than 8 units of ANU (airplane nose up) trim - usually at heavier weights - KEEP THE POWER IN WHILE FLARING!! Reason being, the stab is trimmed so far nose up (stab leading edge down) that the elevator tabs are somewhat blanketed by the extreme angle of the stab... so if you get a sinker and pull back, nothing happens! Power saves the day.
Another thing, just like the 727.. many times, if you get a sinker the last 20 feet in landing, instead of pulling back, releasing the control pressure and even nudging the yoke slightly FORWARD actually raises the main gear (so far behind the center of lift) and cushions the landing quite nicely. Feels weird but once you get used to it, it gets better.
Folks have said that flying the MD80 feels like balancing a dump truck perched on top of a bowling ball. The control forces are heavier than most Boeings (due to the tabs concept). I agree. BUt after flying it for so long, one develops a certain finesse in flying it and managing the quirky autopilot modes, learning to anticipate it and at that point, it becomes a pleasure to hand fly. And it's true hand flying (direct cables!)
Have fun. 7 years/4500 hours and never any surprises.
