Narrative:

On takeoff from sea, aircraft track may have exceeded the noise abatement corridor limits. Flight director commands from the FMS were initially used. However, VOR raw data indicated a 1.5 DOT deviation from centerline. A correction was immediately applied to center the VOR. The corridor is 2300 ft either side of the 158 degree radial and this distance may have been exceeded before the correction was made.
