Narrative:
I was advised about a possible deviation from a departure RNAV SID. Prior to departure; as per the takeoff checklist; we observed the FMC was lined up with the runway. During the initial climb LNAV was selected out of 400 ft and the right autopilot was engaged out of 500 ft; as per company RNAV departure procedures. I observed the airplane deviate to the right .2 NM and returned on course with the autopilot engaged in the LNAV mode. This aircraft is a non-pegasus airplane.
