MD-80 thrust reversers are canted slightly inboard at the top to reduce FOD while in reverse. When pulling anymore than 1.30 EPR on landing roll out the exhaust from the upper thrust reverser bucket will disturb the airflow over the rudder. When conditions are right this can induce a possible loss of directional control at slower speeds on rollout.
Normal procedure on landing is to pull anywhere from idle reverse to 1.30 EPR until 80 knots. At 80 knots slowly start reducing thrust and come out of reverse at the 60 knot call.
