Narrative:

First officer's leg -- misunderstood the need to maintain 200 KIAS or less below ord class B airspace on departure from mdw. We leveled at 3000 ft MSL and maintained 200 KIAS until given climb clearance to 4000 ft MSL. At that time he began a climb and allowed the aircraft to accelerate to approximately 215-220 KTS. I instructed him to pitch up to maintain 200 KTS. He did so and reduced speed to 200 KTS until passing 3600 ft MSL on climb. We had read the departure problem in the commercial manual and discussed the procedure prior to pushback. Apparently he misunderstood the need to maintain 200 KTS until 3000 ft AGL, not 3000 ft MSL. That departure is not the best for an automated aircraft such as the A320. Too much heads down time making sure the ship is doing what you want it to.

Title: FO OF AN AIRBUS A320 EXCEEDED THE MAX AIRSPD IN AN ARPT TERMINAL AREA AND UNDER CLASS B AIRSPACE.

Narrative: FO'S LEG -- MISUNDERSTOOD THE NEED TO MAINTAIN 200 KIAS OR LESS BELOW ORD CLASS B AIRSPACE ON DEP FROM MDW. WE LEVELED AT 3000 FT MSL AND MAINTAINED 200 KIAS UNTIL GIVEN CLB CLRNC TO 4000 FT MSL. AT THAT TIME HE BEGAN A CLB AND ALLOWED THE ACFT TO ACCELERATE TO APPROX 215-220 KTS. I INSTRUCTED HIM TO PITCH UP TO MAINTAIN 200 KTS. HE DID SO AND REDUCED SPD TO 200 KTS UNTIL PASSING 3600 FT MSL ON CLB. WE HAD READ THE DEP PROB IN THE COMMERCIAL MANUAL AND DISCUSSED THE PROC PRIOR TO PUSHBACK. APPARENTLY HE MISUNDERSTOOD THE NEED TO MAINTAIN 200 KTS UNTIL 3000 FT AGL, NOT 3000 FT MSL. THAT DEP IS NOT THE BEST FOR AN AUTOMATED ACFT SUCH AS THE A320. TOO MUCH HEADS DOWN TIME MAKING SURE THE SHIP IS DOING WHAT YOU WANT IT TO.
