Narrative:
After takeoff on 26L at atl on a rmbln 7 RNAV SID the tower called and asked 'you are in a right turn; correct?' I said that we were on the rmbln 7. The tower controller said to turn right to 300 degrees; which we immediately did. Just prior to the turn I noticed that the north wind had blown us slightly south of the magenta line. The wind was out of the north at 55 KTS. We maintained the 300 heading as we switched to departure. Departure asked if we saw the traffic at 10 o'clock. We did; and told him so. It was an rj; turning away from us. The controller said to maintain visual contact. He then asked if we had difficulty on the RMBLN7. I assumed that this was his way of asking me why we were on a heading. I replied that the north wind had caused a southerly drift; and hence the 300 heading. He then cleared us direct to rmbln.we should always engage the autopilot on RNAV sids. If the tower was concerned about a conflict; I would have appreciated an immediate instruction to correct; rather than start the conversation with a question (which wasted a few seconds before the correction was issued).
