B737 off runway 28 bwi copied clearance turn heading 120 degrees, climb 15000 ft, maintain 250 KTS per center request. Leaving 5000 ft cleared to maintain 6000 ft. Overshot 6000 ft by 300 ft and cleared at the same time to 9000 ft. Departure controller advised had missed the readback of 15000 ft. Reporter feels controller is using too much verbiage in his issue of clearance.

Narrative:

On climb out from bwi (runway 28) departure gave us 'turn to heading 120 degrees, climb to 15800 ft, maintain 250 KTS -- the 250 KTS is at center request.' we read clearance back. Just out of 5000 ft departure said 'maintain 6000 ft.' we overshot 6000 ft by +/- 300 ft. At the same time we were told to maintain 9000 ft. I told departure we had been given 15000 ft as a clearance altitude. Departure said 'I missed your readback.' I don't know if we set off any lights but there was miscom on the clearance altitude. Giving a heading, climb and speed request, along with who is requesting the speed, is too much verbiage in one sentence. If I were only cleared to 5000 ft why mention 250 KTS at all? The same information as to who was requesting the speed was also being given to every aircraft departure talked to.

Original NASA ASRS Text

Title: B737 OFF RWY 28 BWI COPIED CLRNC TURN HDG 120 DEGS, CLB 15000 FT, MAINTAIN 250 KTS PER CTR REQUEST. LEAVING 5000 FT CLRED TO MAINTAIN 6000 FT. OVERSHOT 6000 FT BY 300 FT AND CLRED AT THE SAME TIME TO 9000 FT. DEP CTLR ADVISED HAD MISSED THE READBACK OF 15000 FT. RPTR FEELS CTLR IS USING TOO MUCH VERBIAGE IN HIS ISSUE OF CLRNC.

Narrative: ON CLBOUT FROM BWI (RWY 28) DEP GAVE US 'TURN TO HDG 120 DEGS, CLB TO 15800 FT, MAINTAIN 250 KTS -- THE 250 KTS IS AT CTR REQUEST.' WE READ CLRNC BACK. JUST OUT OF 5000 FT DEP SAID 'MAINTAIN 6000 FT.' WE OVERSHOT 6000 FT BY +/- 300 FT. AT THE SAME TIME WE WERE TOLD TO MAINTAIN 9000 FT. I TOLD DEP WE HAD BEEN GIVEN 15000 FT AS A CLRNC ALT. DEP SAID 'I MISSED YOUR READBACK.' I DON'T KNOW IF WE SET OFF ANY LIGHTS BUT THERE WAS MISCOM ON THE CLRNC ALT. GIVING A HDG, CLB AND SPD REQUEST, ALONG WITH WHO IS REQUESTING THE SPD, IS TOO MUCH VERBIAGE IN ONE SENTENCE. IF I WERE ONLY CLRED TO 5000 FT WHY MENTION 250 KTS AT ALL? THE SAME INFO AS TO WHO WAS REQUESTING THE SPD WAS ALSO BEING GIVEN TO EVERY ACFT DEP TALKED TO.
