CL65. AFTER HAVING PRESSURIZATION PROBS THE CREW ASKED TO STOP CLB AT 10000 FT. WHEN GIVING VECTORS; ATC DID NOT SPECIFY THE TURN AS THE LONG WAY AROUND AND THE ACFT GOT CLOSE TO RESTR AREA.

Narrative

PRIOR TO DEP; ONE OF THE ACFT'S PAC WAS DMI. THIS IS NOT NORMALLY A PROB ON A SHORT FLT LIKE OUR IAD TO PWM; WITH THE INOP PAC REQUIRING A CRUISE ALT LIMIT OF FL250; OR BELOW. AFTER TKOF; THAT CAPT INCORRECTLY XFERRED THE BLEEDS FROM THE APU TO THE ENGS CAUSING AN OVERPRESSURE OF THE OPERATIVE PAC. I NOTICED THE FAILURE; CALLED FOR THE QRH PROC AND INFORMED ATC THAT WE HAD A PRESSURIZATION PROB AND NEEDED TO REMAIN AT 10000 FT UNTIL WE SORTED IT OUT. ATC ASKED IF WE NEEDED TO RETURN TO IAD AND I REPLIED NOT AT THIS TIME; THAT WE SHOULD BE ABLE TO SORT OUT THE PROB QUICKLY; AND THAT WE WOULD CONTINUE TO PWM AND I WOULD ADVISE THEM IF WE NEEDED TO RETURN; OR WHEN THE PROB WAS CORRECTED. AT THIS TIME WE WERE N OF IAD ON A 120 DEG HDG RADAR VECTORS TO THE SWANN INTXN (E OF BAL). ATC TURNED US L TO A 360 DEG HDG. AFTER A FEW MINS; ATC GAVE US A TURN TO 190 DEGS. THEY DID NOT STATE WHY AND WE WERE BUSY SORTING OUT THE PROB; SO WE COMPLIED. AS STATED; WE DID NOT NEED TO RETURN. THERE IS SOME CONFUSION ON THE DIRECTION OF THE TURN. I STARTED THE TURN TO THE R; BUT ATC QUESTIONED THE DIRECTION AND SAID THAT IT WAS A L TURN TO 190 DEGS; AND STATED THAT THEY HAD PROHIBITED AREAS IN DC THAT WE WOULD GET TOO CLOSE TO WITH A R TURN. AT THIS POINT; WE WERE WELL N OF DC TO HAVE THE TURN INTERFERE WITH THE PROHIBITED AREAS. AFTER COMPLYING WITH ATC; IN THE L TURN BACK AROUND TO THE N; AFTER PASSING A NORTHERLY HDG; ATC STARTED REPEATING (IT SEEMED LIKE THEY WERE YELLING) THAT WE WERE TOO CLOSE TO THE PROHIBITED AREA AND THAT IF WE DID NOT INCREASE OUR RATE OF TURN THAT F-16 WOULD BE SCRAMBLED AFTER US. I DISCONNECTED THE AUTOPLT AND INCREASED THE BANK ANGLE TO 40 DEGS FOR UNTIL I WAS THROUGH A W HDG AND THEN RETURNED TO A NORMAL 30 DEG BANK. IT SEEMED THAT ATC DID NOT WANT US TO CONTINUE NEBOUND TOWARD OUR DEST AT 10000 FT FOR WHATEVER REASON UNTIL WE GOT THE OTHER PAC ON LINE; SO I ASKED TO HOLD UNTIL WE SORTED OUT THE PROB; EITHER PRESENT POS; FDK; OR MRB. ATC SUGGESTED MRB WITH A CLRNC TO HOLD SE AT 10000 FT. I TURNED R; WESTERLY; TOWARDS MRB TO HOLD; BUT THE CAPT SORTED OUT THE INOP PAC AND WE COULD NOW CONTINUE TO PWM. I INFORMED ATC AND THEY GAVE US VECTORS TO SWANN THEN DIRECT SWANN AND WE COMPLETED THE TRIP. THERE WAS NO REASON FOR ATC TO HAVE US ANYWHERE NEAR THE RESTR AREA; SO THAT I HAD TO TAKE ACTION TO INCREASE THE ACFT BANK ANGLE; INCREASING THE RATE OF TURN; TO AVOID THE AREA TO COMPLY WITH ATC INSTRUCTIONS.
