Route Offset
Route offsets are selected on the RTE page. The OFFSET prompt displays on the RTE page when the airplane is not on a SID, STAR, or transition. Entering a distance value into the OFFSET dashes creates the selected offset. An offset propagates along the route from the active waypoint until a discontinuity, approach, approach transition, holding pattern, course change of greater than 135 or end of route is reached. An offset can be removed by deleting the offset waypoints, proceeding direct, or entering an offset value of zero.
PEGASUS FMC
The offset is shown as a white dashed line on the HSI until the offset modification is executed or erased.
After execution, the offset route is shown as a dashed magenta line on the HSI. The original route remains a solid magenta line.
If LNAV is engaged when the offset is executed, the airplane turns to an intercept heading to captures the offset course.

Enter the necessary offset. When executed, the CDU OFST light illuminates.
