Enter the identifier of the reference waypoint (normally an off–route waypoint) onto the FIX line. Enter the desired radial or distance from the FIX on a RAD/DIS line, or line select the ABM prompt if the desired radial from the FIX is perpendicular to the present route/course.
Time and distance to go ................................................................. Check
Check ETA and DTG, as desired.
Note: If ETA and DTG are not displayed, the fix radial and/or distance do not intersect the route.
Changing Destination
RTE page ........................................................................................Select
Enter the new destination over the original DEST. Enter desired routing to the new destination using the RTE, RTE LEGS, and ARRIVALS pages, as appropriate. Correct any ROUTE DISCONTINUITY.
EXEC key .........................................................................................Push Observe the MOD RTE or MOD RTE LEGS page changes to ACT.
Note: If destination is changed during climb, performance predictions may be blanked if the new flight plan is incompatible with the entered cruise altitude. Correct by entering a lower CRZ ALT on the CLB page.

Entering Holding Fix Into Route
HOLD key ........................................................................................ Push
(If RTE HOLD page is displayed, observe NEXT HOLD prompt.
Line select 6L until (RTE LEGS) HOLD AT page is displayed.)
Observe HOLD AT box prompts and PPOS prompt (if in flight) are
displayed. Enter the holding fix in line 6L, or line select PPOS.
If the holding fix is a waypoint in the active route, or PPOS was selected, observe MOD RTE HOLD page displayed. If the holding fix is a waypoint not in the active route, observe message HOLD AT XXXXX displayed in the scratch pad. Enter the holding fix into the route by line selecting in the desired waypoint sequence. Observe the MOD RTE HOLD page displayed. If displayed holding details are incorrect or inadequate, enter correct information on appropriate line(s).
EXEC key ........................................................................................ Push Observe MOD RTE HOLD page changes to RTE HOLD (ACT RTE HOLD if holding at PPOS).
Exiting Holding Pattern
HOLD key ........................................................................................ Push Observe EXIT HOLD prompt displayed.
EXIT HOLD line select key............................................................. Push Observe EXIT HOLD prompt changes to EXIT ARMED.
EXEC key ........................................................................................ Push Observe EXIT ARMED is highlighted in reverse video and LNAV flight returns to the holding fix and resumes the active route.
Note: The holding pattern may be exited by performing a DIRECT TO modification if desired. In this case, the flight path may not return to the holding fix before proceeding to the selected waypoint.
Note: A late sequencing of the hold exit waypoint may occur if multiple route modifications are performed just prior to exiting the hold. LNAV guidance may be temporarily interrupted while sequencing the hold exit waypoint.

Along Track Displacement
RTE LEGS page .............................................................................Select
Line select the reference waypoint to the scratch pad. Add a “/” and the + or – distance desired. (EX: SEA/15 for a point 15 miles downtrack from SEA)
Line select the reference waypoint. (The FMC will automatically
position the created waypoint to appropriate position.)
EXEC key .........................................................................................Push Observe the MOD RTE LEGS page change to ACT.
Entering Created Waypoints on the Route or Route Legs Pages
Note: Created waypoints are stored in the temporary navigation data base for one flight only.
RTE or RTE LEGS page.................................................................Select
Using any of the following methods, key into the scratch pad the parameters which define the new created waypoint (place identifiers must already be stored in one of the FMC data bases):
.
Place bearing/distance (for example, SEA250/40);
.
Place bearing/place bearing (for example, SEA180/ELN270);
