Narrative:
Departed off mdw runway 31C at XA20 with normal departure clearance to turn right to a heading of 350 degrees, maintain 3000 ft, cleared for takeoff. This was my second departure out of mdw in the airbus. However, I have had numerous prior departures in EFIS equipped B737-300's. Company SOP is to select the climb detent with 'level climb' flashes on the pfd (approximately 1500 ft AGL) for a normal climb profile. My first departure out of mdw met all parameters. However, due to a high climb rate, 200 KT speed restr below the class B airspace, and a relatively low leveloff altitude, I was not happy with the drastic power reduction commanded by the autothrust system at leveloff due to many things coming together simultaneously. In an effort to make the climb profile smooth and less disconcerting for the passenger, I briefed the first officer on a technique I felt would accomplish my objective. I failed to include one very critical requirement necessary to make the procedure work. The brief went something like this:
Original NASA ASRS Text
Title: A319 FLC EXCEEDS AIRSPD AND OVERSHOOTS ALT ON DEP FROM MDW.
Narrative: DEPARTED OFF MDW RWY 31C AT XA20 WITH NORMAL DEP CLRNC TO TURN R TO A HDG OF 350 DEGS, MAINTAIN 3000 FT, CLRED FOR TKOF. THIS WAS MY SECOND DEP OUT OF MDW IN THE AIRBUS. HOWEVER, I HAVE HAD NUMEROUS PRIOR DEPS IN EFIS EQUIPPED B737-300'S. COMPANY SOP IS TO SELECT THE CLB DETENT WITH 'LEVEL CLB' FLASHES ON THE PFD (APPROX 1500 FT AGL) FOR A NORMAL CLB PROFILE. MY FIRST DEP OUT OF MDW MET ALL PARAMETERS. HOWEVER, DUE TO A HIGH CLB RATE, 200 KT SPD RESTR BELOW THE CLASS B AIRSPACE, AND A RELATIVELY LOW LEVELOFF ALT, I WAS NOT HAPPY WITH THE DRASTIC PWR REDUCTION COMMANDED BY THE AUTOTHRUST SYS AT LEVELOFF DUE TO MANY THINGS COMING TOGETHER SIMULTANEOUSLY. IN AN EFFORT TO MAKE THE CLB PROFILE SMOOTH AND LESS DISCONCERTING FOR THE PAX, I BRIEFED THE FO ON A TECHNIQUE I FELT WOULD ACCOMPLISH MY OBJECTIVE. I FAILED TO INCLUDE ONE VERY CRITICAL REQUIREMENT NECESSARY TO MAKE THE PROC WORK. THE BRIEF WENT SOMETHING LIKE THIS:
