Airway Intercept
Just as in intercept to/from, LNAV can be used to intercept an airway. An airway
intercept changes the active waypoint on the RTE and LEGS pages.
Enter the airway identifier under VIA on line 1 of the RTE page. Boxes display
under TO. Enter the desired airway exit waypoint in the boxes. For this
open-ended airway intercept, the FMC selects the waypoint preceding the closest
abeam location as the starting waypoint of the airway. This waypoint displays on
line 1. The entered airway and the desired exit point display on line 2. Executing
the modification makes the leg to the FMC selected airway start waypoint the
active leg segment.
If the clearance heading intercepts the active leg segment, LNAV can be armed
and the intercept will occur. In most airway intercept situations, the commanded
heading will not intercept the active leg.
If the clearance heading does not intercept the active leg segment, use the
intercept–course–to procedure to make the course inbound to the waypoint (after
the crossing location) the active leg segment.
Example
The active route is direct to EPH, then direct to MWH. ATC clears the airplane to:
• turn right heading 110°
• intercept V2 to MWH.
Following the V2 modification to MWH and execution, the LEGS page displays
this waypoint sequence:
• BANDR
• BEEZR
• ELN
• PLUSS
• MWH.

Modify the LEGS page using a course intercept to the waypoint after the crossing
location. In this case, it would be PLUSS. PLUSS becomes the active waypoint
on the V2 airway. The LEGS page now displays:

Enter desired airway exit point in the boxes.
After entering MWH in the boxes:

• the airway line moves down one line
• dashes display in the VIA to the start airway waypoint.

Following modification and execution of the course intercept procedure to
PLUSS, the LEGS page displays PLUSS as the active waypoint. LNAV can be
armed and the airway intercept can be completed.
Route Offset
Select route offsets on the RTE page 1. The OFFSET prompt displays when the
airplane is in flight and not on a SID, STAR, or transition. The offset displays as
a white dashed line on the ND until the offset modification is executed or erased.
After execution, the offset route displays as a dashed magenta line. The original
route continues to display as a solid magenta line. When executing the offset
