Narrative:

I was flying a challenger 604. We were cleared for takeoff on runway 33 at dca, immediately behind a B727 on runway 36. Right after takeoff we were in loose formation with the B727 who turned to about a 330 degree heading to follow the river out. We also had a clearance to follow the river out to the northwest. Shortly after takeoff (I can't remember if it was departure or tower) we were instructed to make a hard right turn and get in behind the B727 and follow the river. I made the turn, (about 90 degrees to the right) but I closed the gap on the B727. Now I am directly over the river, heading northeast, with the B727 close in front of me flying northwest out the river. I delayed my immediate turn back to the northwest so as not to conflict with the B727. I was also very concerned with his climb out wake turbulence. He was about 1 1/2 mi ahead of us. We had him visual and on TCASII. Due to my delay in turning back up the river, I may have violated P-56 on the east side of the river. Departure now told me to make an immediate left turn to 290 degrees to keep me clear of P-56 and to give us spacing on the B727. He stated he understood we were put in a precarious situation, but didn't want us in P-56. I felt my maneuvering was necessary for safe spacing behind. I believe the tower should not have issued us a rapid clearance behind the B727 in which he would be turning to approximately our heading. I did not realize he was going out the river departure with us.

Title: TFC CONFLICT AND NEAR P-56 INCURSION WHEN 2 ACFT DEPART DCA, VA, FROM DIFFERENT RWYS.

Narrative: I WAS FLYING A CHALLENGER 604. WE WERE CLRED FOR TKOF ON RWY 33 AT DCA, IMMEDIATELY BEHIND A B727 ON RWY 36. RIGHT AFTER TKOF WE WERE IN LOOSE FORMATION WITH THE B727 WHO TURNED TO ABOUT A 330 DEG HDG TO FOLLOW THE RIVER OUT. WE ALSO HAD A CLRNC TO FOLLOW THE RIVER OUT TO THE NW. SHORTLY AFTER TKOF (I CAN'T REMEMBER IF IT WAS DEP OR TWR) WE WERE INSTRUCTED TO MAKE A HARD R TURN AND GET IN BEHIND THE B727 AND FOLLOW THE RIVER. I MADE THE TURN, (ABOUT 90 DEGS TO THE R) BUT I CLOSED THE GAP ON THE B727. NOW I AM DIRECTLY OVER THE RIVER, HEADING NE, WITH THE B727 CLOSE IN FRONT OF ME FLYING NW OUT THE RIVER. I DELAYED MY IMMEDIATE TURN BACK TO THE NW SO AS NOT TO CONFLICT WITH THE B727. I WAS ALSO VERY CONCERNED WITH HIS CLBOUT WAKE TURB. HE WAS ABOUT 1 1/2 MI AHEAD OF US. WE HAD HIM VISUAL AND ON TCASII. DUE TO MY DELAY IN TURNING BACK UP THE RIVER, I MAY HAVE VIOLATED P-56 ON THE E SIDE OF THE RIVER. DEP NOW TOLD ME TO MAKE AN IMMEDIATE L TURN TO 290 DEGS TO KEEP ME CLR OF P-56 AND TO GIVE US SPACING ON THE B727. HE STATED HE UNDERSTOOD WE WERE PUT IN A PRECARIOUS SIT, BUT DIDN'T WANT US IN P-56. I FELT MY MANEUVERING WAS NECESSARY FOR SAFE SPACING BEHIND. I BELIEVE THE TWR SHOULD NOT HAVE ISSUED US A RAPID CLRNC BEHIND THE B727 IN WHICH HE WOULD BE TURNING TO APPROX OUR HEADING. I DID NOT REALIZE HE WAS GOING OUT THE RIVER DEP WITH US.
