Narrative:

I was pilot-in-command of aircraft X from dca. After all pre-departure checklists were completed; we taxied to dca runway 01 for takeoff. I had glanced over at the first officer's (first officer's) side to see if everything was set up and I recall; everything looked normal. When we were cleared for takeoff we made a normal takeoff; broke ground; and did the normal post-rotation clean-up of the aircraft. When we reached the fix on the departure dca SID that turned us up the river; I knew something was wrong. I grabbed the yoke and made an immediate left turn to turn the aircraft back on course. When I looked at the first officer's crts I noted they were configured incorrectly for the takeoff so I simultaneously reached over and corrected his displays. After I reconfigured the pfd; I engaged LNAV and VNAV to their normal takeoff configuration. At this time I selected the auto pilot on. While selecting the appropriate LNAV and VNAV buttons I glanced out my left window and saw the river below me. From my view I was still over the river. Shortly afterwards we were handed off from tower; to departure; then on to other center frequencies. At this time I'm not sure how many handoffs were made but at some point; we were queried if we had a minute to talk. I responded 'yes; go ahead'. The controller then informed us that we had a 'possible traffic deviation.' I started thinking about it and did not think I had done anything wrong. When I landed [at destination airport]; I was then informed that we had penetrated the P-56A airspace that protects the white house. At that point my first officer and I went through the proper channels in talking with my chief pilot; TRACON; etc. After the interview; I was told they did not believe there would be any further law enforcement action on their part.the event occurred because one pilot was not in FMS needles when the airplane wanted to turn it was not indicating to that pilot to do that. I will double check the screens and navigation tools that are supposed to be on for that particular flight for takeoff.

Title: Air carrier flight crew reported a procedural deviation while departing Washington National Airport (DCA) which resulted in the penetration of Prohibited Area P-56.

Narrative: I was Pilot-in-Command of Aircraft X from DCA. After all pre-departure checklists were completed; we taxied to DCA runway 01 for takeoff. I had glanced over at the First Officer's (FO's) side to see if everything was set up and I recall; everything looked normal. When we were cleared for takeoff we made a normal takeoff; broke ground; and did the normal post-rotation clean-up of the aircraft. When we reached the fix on the departure DCA SID that turned us up the river; I knew something was wrong. I grabbed the yoke and made an immediate left turn to turn the aircraft back on course.
