Narrative:
Approach cleared us for visual approach runway 10R at pit, asked us to reduce speed to 160 KTS and follow a beech commuter airliner. I called for 1 degree flaps and reset the speed command bug to 160 KTS. Then there was confusion about which aircraft we were to follow. Distracted by that I forgot to call for 5 degrees flaps. The airspeed went to 160 KTS with flaps 1 degree set, below maneuver speed. Aircraft was flown below maneuver speed for flaps 1 degree for 30 seconds. Traffic sequence was resolved and I executed more flaps.

Title: LGT FLC REDUCES SPD BELOW MANEUVERING SPD FOR FLAP CONFIGN. FLIES ABOUT 30 SECONDS THEN CORRECTS.
Narrative: APCH CLRED US FOR VISUAL APCH RWY 10R AT PIT, ASKED US TO REDUCE SPD TO 160 KTS AND FOLLOW A BEECH COMMUTER AIRLINER. I CALLED FOR 1 DEG FLAPS AND RESET THE SPD COMMAND BUG TO 160 KTS. THEN THERE WAS CONFUSION ABOUT WHICH ACFT WE WERE TO FOLLOW. DISTRACTED BY THAT I FORGOT TO CALL FOR 5 DEGS FLAPS. THE AIRSPD WENT TO 160 KTS WITH FLAPS 1 DEG SET, BELOW MANEUVER SPD. ACFT WAS FLOWN BELOW MANEUVER SPD FOR FLAPS 1 DEG FOR 30 SECONDS. TFC SEQUENCE WAS RESOLVED AND I EXECUTED MORE FLAPS.
