Displays the type of navaid for each duplicate name.
Displays the latitude/longitude for each duplicate name.
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 1L of the RTE page. Boxes display
under TO for an open-ended airway intercept. Enter the desired airway exit
waypoint in the boxes. The FMC selects the waypoint preceding the closest abeam
location as the starting waypoint of the new airway. This waypoint displays under
TO on line 1R. The entered airway and the selected exit point display on line 2.
Executing the modification makes the FMC selected first waypoint the active
waypoint; BANDR in the example that follows.
If the clearance heading intercepts the new route before the next downtrack
waypoint (BEEZR), LNAV can be armed and will capture, and the active
waypoint will sequence to the next downtrack waypoint (BEEZR).
If the clearance heading does not intercept the new route before the next
downtrack waypoint, the EICAS advisory message FMC INTERCEPT HDG is
displayed. 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
