Narrative:

I copied the clearance on the ground before departure. I had trouble understanding the guy on the clearance delivery. I read the clearance back after I copied it. 'Cleared to cle, 328 degree radial, intercept J-211, etc.' the captain and I discussed the departure. Most of what we talked about was the noise abatement procedures. I took off and was climbing steep so we would be quiet, as the procedures require. We went in the clouds soon after takeoff. Departure control asked us if were cleared to turn and track the 328 degree radial, the captain replied 'yes.' they gave us a left turn and I turned. The departure controller then said we should have turned because of prohibited area 56.

Title: ACR MLG TRACK DEVIATION PENETRATED PROHIBITED AREA.

Narrative: I COPIED THE CLRNC ON THE GND BEFORE DEP. I HAD TROUBLE UNDERSTANDING THE GUY ON THE CLRNC DELIVERY. I READ THE CLRNC BACK AFTER I COPIED IT. 'CLRED TO CLE, 328 DEG RADIAL, INTERCEPT J-211, ETC.' THE CAPT AND I DISCUSSED THE DEP. MOST OF WHAT WE TALKED ABOUT WAS THE NOISE ABATEMENT PROCS. I TOOK OFF AND WAS CLBING STEEP SO WE WOULD BE QUIET, AS THE PROCS REQUIRE. WE WENT IN THE CLOUDS SOON AFTER TKOF. DEP CTL ASKED US IF WERE CLRED TO TURN AND TRACK THE 328 DEG RADIAL, THE CAPT REPLIED 'YES.' THEY GAVE US A L TURN AND I TURNED. THE DEP CTLR THEN SAID WE SHOULD HAVE TURNED BECAUSE OF PROHIBITED AREA 56.
