Aircraft; Human Factors; Procedure
Captain was flying River Visual to Runway 19 DCA. Washington Tower asked us to square our turn to final. The Captain complied; but it turns out that the aircraft touched P-56. On taxi in; Ground Control asked us to call Potomac Approach. The Captain complied and at the end of the short conversation; Potomac said that the previous two aircraft (different airlines) were asked the same request from Tower and that they too had touched P-56. Two things; have P-56 waypoint as a reference point on NAV display on approach and to get Washington Tower to never issue ATC instructions to square the turn to final Runway 19.
Air carrier First Officer reported a P56 airspace violation after the Control Tower instructed the flight crew to square turn to final while on the RIVER VISUAL RWY 19 to DCA airport.
