Modified (MOD)

Displays MOD when the route is being modified.

Line data is valid for the modified route.

Deleting Waypoints

Waypoints can be removed from the RTE LEGS page. There are two normal

methods to remove a waypoint:

• delete the waypoint using the DEL function key (not possible for the

active waypoint and some conditional waypoints)

• resequence the route by moving a down-route waypoint up in the

sequence and automatically removing all waypoints that are between.

During the deletion process, all of the route prior to the deletion point remains

unchanged. Removing a waypoint using the DEL function key causes a route

discontinuity to replace the deleted waypoint.

Bypass Notification

A waypoint (BAN01) has been entered into the route which is very close to

another route waypoint (BANDR). It is impossible for the airplane to turn and

capture the leg between BANDR and BAN01, so a bypass is noted.

Turn construction is based upon FMC criteria which assume that LNAV is

engaged. Normal turn construction may not be possible under certain

combinations of airspeed, short leg length, and a significant change in leg

direction. If normal turn construction cannot provide a continuous path, the FMC

bypasses the affected leg and uses alternative turn construction to intercept the leg

to the subsequent waypoint. When the bypass is for the active waypoint, the

waypoint remains active until the airplane passes abeam.

Any mandatory altitude-crossing restriction for the bypass waypoint is still

observed if VNAV is engaged, based on passing abeam the waypoint.

If a triple bypass condition occurs (bypass of three consecutive legs), a route

discontinuity will be inserted.

Removing Discontinuities

A discontinuity exists when the FMC is unable to determine the route leg

following a waypoint. Discontinuities are removed by linking the route segment

following the discontinuity to the route segment preceding the discontinuity.

The next desired waypoint from the subsequent route is copied into the CDU

scratchpad and entered into the discontinuity, just as when adding a waypoint.

ROUTE DISCONTINUITY

The active route shows a discontinuity. The airplane must fly direct from LAC01

to BANDR. The BANDR waypoint is copied into the scratchpad in preparation to

remove the discontinuity. Any waypoint from the route can be copied into the

scratchpad to remove the discontinuity.

2

Continuous Route

BANDR is copied into the box prompts to remove the discontinuity.

Entering a waypoint which does not already exist on the route moves the

discontinuity one waypoint farther down the route.

DIR INTC Key

[Option - CDU]

Proceeding direct to a waypoint or intercepting a course to a waypoint may also

be accomplished by using the direct intercept (DIR INTC) mode select key.

Pushing the DIR INTC key adds box prompt options to the bottom of the ACT

RTE LEGS page.

Using line select or manual entry, the desired waypoint is entered into the

scratchpad. The waypoint is then moved into the appropriate boxes. Subsequent

operations are identical to those described in the Intercept Course section.

Abeam Points (ABEAM PTS)

Selecting the prompt permits the retention of waypoints following a direct-to

modification. The FMC creates and displays points on the new route which are

abeam the waypoints bypassed by the route modification.

In the example, the route has been modified to proceed direct to OTT. This

modification bypasses CYN and ENO.

2

Abeam Waypoints

CYN01 and ENO01 have been created. Data and status corresponding to the

parent waypoints is passed to the abeam waypoints. If abeam distance is less than

100 nm, only the wind data is passed to the abeam waypoint.

The following diagram depicts the situation.

Abeam waypoints will not be generated for floating (non-fixed) waypoints; if the

abeam distance exceeds 700 nm; or if the abeam waypoint would fall within 10

nm of either the present position or the direct-to waypoint.

If two or more identical (within 1 nm of each other) abeam waypoints are

generated, only one will be designated.

Offset Distance (OFFSET DIST)

The desired lateral offset distance is entered on line 2L In the example, the 10.0

Entry results in display of start and end waypoint fields.

Dashes are displayed if current leg is valid for offset. Box prompts are displayed

Offset will begin at first valid offset leg after the start waypoint.

Deletion of start waypoint (or no entry) will result in offset beginning at first valid
