Fix Information Page
Two identical fix information pages are used to create waypoint fixes and
waypoints for the ND. Some of the created waypoints can be copied into the route.
Magnetic/True Bearing
Magnetic or true fix bearings depend on airplane location. Refer to FMC Polar
Operations, Flight Management Navigation, section 31.
1 FIX
Valid entries are airports, navaids, and waypoints from the navigation database.
Selected fix displays on the ND.
2 Bearing/Distance (BRG/DIS), ETA, DTG, ALT
Distance Entry:
• valid entry is /YYY
• leading zeros can be omitted for distance entries
Distances from the fix display on the ND as a circle around the fix.
When the distance intersects the active route, the ETA, DTG, and altitude at the
intersection display for the closest of the two intersections.

Bearing Entry:
• valid entry is a bearing from the fix, XXX
• slash (/) not required
Bearings from the fix display on the ND as radial lines from the fix.
When the bearing intersects the active route, the ETA, DTG, and altitude at the
intersection display.
ETA – displays the estimated time of arrival to the intersection point.
DTG – displays the distance to go to the intersection point.
ALT – displays the predicted altitude at the intersection point.
Bearing/distance entries do not display ETA, DTG, or predicted altitude.
Line selection copies the fix place/bearing/distance into the scratchpad. Distance
displays to the nearest tenth of a nautical mile. This fix can be placed in the route
on a LEGS or RTE page as a waypoint.
3 ABEAM
Displays ABEAM prompt.
Push - displays bearing and distance from the fix perpendicular to the nearest
segment of the flight plan path, and ETA, DTG, and altitude at the intersection
point.
Second push - copies the fix place/bearing/distance definition into the scratchpad.
This fix can be placed in the route on a LEGS or RTE page as a waypoint.
4 ERASE FIX
Push – removes all fix data from the page and the ND.
5 Bearing/Distance From (BRG/DIS FR)
Displays the bearing and distance of the airplane from the fix.
6 Predicted Distance to ETA or Altitude (PRED ETA-ALT)
Valid entry is altitude, flight level, or time. Time entry must be followed by “Z”.
Entering an altitude or flight level displays the predicted along track distance and
altitude or flight level on this line. The predicted airplane position displays on the
ND route line as a green circle with the entered altitude/flight level.
Entering a time displays the predicted along track distance and the time on this
line. The predicted airplane position displays on the ND route line as a green circle
with the entered ETA.

Route and Waypoint Data
Route Data Page
The route data page displays data for each waypoint on ACT RTE X LEGS page.
This page also allows access to the WIND page. This page is available only for the
active route.
This page allows a downlink request for enroute wind information and allows
review of uplinked enroute wind information.
The ETA and calculated fuel remaining display for each waypoint. Manual entry
is not possible.
