Narrative:

Washington national northwest noise abatement procedures. Departure asked us to remain over the river at approximately 3-4 DME from dca during northwest departure. Due to strong northwest winds I was using more bank than usual during departure (25-30 degree) for turns. After turning left for left bend in river at approximately 3 DME, I started rolling into right bank to continue over river and that's when ATC called. I assume due to bank (25 degree left) then rolling to right the aircraft drifted a little south of river.

Original NASA ASRS Text

Title: CAPT FLYING RIVER DEP OUT OF DCA CAUTIONED BY DEP CTLR TO STAY OVER RIVER.

Narrative: WASHINGTON NATIONAL NW NOISE ABATEMENT PROCS. DEP ASKED US TO REMAIN OVER THE RIVER AT APPROX 3-4 DME FROM DCA DURING NW DEP. DUE TO STRONG NW WINDS I WAS USING MORE BANK THAN USUAL DURING DEP (25-30 DEG) FOR TURNS. AFTER TURNING LEFT FOR LEFT BEND IN RIVER AT APPROX 3 DME, I STARTED ROLLING INTO RIGHT BANK TO CONTINUE OVER RIVER AND THAT'S WHEN ATC CALLED. I ASSUME DUE TO BANK (25 DEG LEFT) THEN ROLLING TO RIGHT THE ACFT DRIFTED A LITTLE S OF RIVER.
