Narrative:

Copilot flying the 'river approach' with a southwest wind. She made the turn wide over rosslyn. The aircraft was aligned along the east bank of the potomac river. It is possible the aircraft came close to entering the prohibited airspace east of the potomac river. I told her to turn further right to avoid drifting into P-56. The tower did not indicate any problem with our flight path. In the future, I will advise the coplts in advance that any westerly wind on this approach requires a tight turn over rosslyn.

Title: B737 CREW HAD POSSIBLE PENETRATION OF P-56 N OF DCA.

Narrative: COPLT FLYING THE 'RIVER APCH' WITH A SW WIND. SHE MADE THE TURN WIDE OVER ROSSLYN. THE ACFT WAS ALIGNED ALONG THE E BANK OF THE POTOMAC RIVER. IT IS POSSIBLE THE ACFT CAME CLOSE TO ENTERING THE PROHIBITED AIRSPACE E OF THE POTOMAC RIVER. I TOLD HER TO TURN FURTHER R TO AVOID DRIFTING INTO P-56. THE TWR DID NOT INDICATE ANY PROB WITH OUR FLT PATH. IN THE FUTURE, I WILL ADVISE THE COPLTS IN ADVANCE THAT ANY WESTERLY WIND ON THIS APCH REQUIRES A TIGHT TURN OVER ROSSLYN.
