Narrative:
After takeoff from lga we were flying the SID which included leveloff at 5000 ft. As we approached 5000 ft it appeared that the autoplt was going to go through the altitude, so I disconnected autoplt and autothrottle and executed a manual leveloff going through the altitude by about 100 ft. At about this time, we received a clearance to turn left to 270 degrees and climb and maintain a higher altitude. My first officer read back 7000 ft but I did not hear this, so I asked him to get confirmation. The frequency was so busy with the controller talking almost continuously that it was 1 min or 2 before we could talk to him. It is company procedure that we not act on a clearance unless we are sure of it. I, therefore, turned left to 270 degrees but maintained 5000 ft. When we finally talked to the controller he turned us further left to 250 degrees (I think) and climbed us to 6000 ft.
Original NASA ASRS Text
Title: ACR FLC DELAYS IN STARTING CLRED TO CLB CLRNC UNTIL ABLE TO BREAK THROUGH FREQ TFC CONGESTION IN ORDER TO CONFIRM CORRECT ALT CLRNC DEPARTING LGA.
Narrative: AFTER TKOF FROM LGA WE WERE FLYING THE SID WHICH INCLUDED LEVELOFF AT 5000 FT. AS WE APCHED 5000 FT IT APPEARED THAT THE AUTOPLT WAS GOING TO GO THROUGH THE ALT, SO I DISCONNECTED AUTOPLT AND AUTOTHROTTLE AND EXECUTED A MANUAL LEVELOFF GOING THROUGH THE ALT BY ABOUT 100 FT. AT ABOUT THIS TIME, WE RECEIVED A CLRNC TO TURN L TO 270 DEGS AND CLB AND MAINTAIN A HIGHER ALT. MY FO READ BACK 7000 FT BUT I DID NOT HEAR THIS, SO I ASKED HIM TO GET CONFIRMATION. THE FREQ WAS SO BUSY WITH THE CTLR TALKING ALMOST CONTINUOUSLY THAT IT WAS 1 MIN OR 2 BEFORE WE COULD TALK TO HIM. IT IS COMPANY PROC THAT WE NOT ACT ON A CLRNC UNLESS WE ARE SURE OF IT. I, THEREFORE, TURNED L TO 270 DEGS BUT MAINTAINED 5000 FT. WHEN WE FINALLY TALKED TO THE CTLR HE TURNED US FURTHER L TO 250 DEGS (I THINK) AND CLBED US TO 6000 FT.
