prior to MEM would be built. Of course, if you need the new
fix after MEM you would use the positive distance, for
example MEM/45 would build the fix 45 beyond MEM in the
flight plan. Again press TMPY ERASE or TMPY INSERT to
get rid of or to activate your changes.
NOTE:You cannot build a new fix inside of the TO waypoint
unless you are on heading mode.
DIR TO page - The page does not look like the F-PLN page now which
helps to reduce any possible confusion. Also, each fix in the
flight plan which can be navigated to is listed with it’s own
prompt. Select the fix you desire or type it into the top box.
You can then ERASE or INSERT.
ABEAM Points can be added. All abeam points will have
prefix AB added. For example, RIC VOR as an abeam point
will appear as ABRIC in the flight plan.
Airbus Gotcha: The FMS2 DOES NOT have the “imaginary centerline”
feature. Actually I believe this was a “bug” in the original FMS software that
turned into a feature. However, the FMS2 will actually handle this differently.
You cannot capture the extended centerline in APPR mode (such as for the
RNAV approach). However, there is a fix for this in FMS2. In the DIR TO page
you can use the RADIAL IN feature to build the inbound course the needed fix.
This will serve as an extended centerline.

Reroutes
One area that gives many new Airbus pilots problems is making changes to the
FMGC flight plan once under way. There are several very common ways to enter
reroutes into the FMGC, depending on the nature of the reroute.
Direct: Press the DIR key and type in the fix (VOR or intersection). Press the
LSK 1L key to enter the fix. The FMGC will automatically enter a T-P (turning
point) to create a FROM waypoint and the fix that is entered will become the TO
waypoint.
Direct then as filed: Use the above method or press the DIR key and then find
the cleared fix in the flight plan. Press the LSK next to the desired waypoint and
it will become the TO waypoint. Using either method all waypoints before the fix
are now cleared and the remainder of the flight plan will be available as filed.
Note: if you are on heading when DIR is used the mode will change to Managed
NAV automatically (in other words, when you go direct in heading mode the
aircraft will automatically engage NAV and go to the direct fix).
Heading to intercept then as filed: Select the cleared intercept heading on the
HDG selector on the FCU. Then you must determine if the segment you have
been cleared to join exists in your flight plan. If it does you only have to clear any
waypoints that are ahead of the segment until you have the proper fix as the TO
waypoint. Use the CLR key to clear any unwanted waypoints then engage NAV.
If the needed segment is not available you must build it. As above first select the
intercept heading. Then type in the fix that will become the FROM. Remember, in
this case you have to create a NAV leg (segment) that does not currently exist in
the FMGC. After typing the new FROM select it to the LSK 2L key and it will
become the TO. Now enter the TO fix on the next line if it does not already exist.
This creates the new leg segment. Now clear the T-P (turning point) on 1L
(clearing the T-P allows each fix to move to its proper TO and FROM position).
Then engage Managed NAV. You can now add any other needed fixes until on
the original route. Then clear any remaining discontinuities.
Offset: To parallel your current course use a lateral revision at the FROM
waypoint. Type in the amount of distance (up to 50 nm) to the side you wish to
parallel the current course and right or left of course. For example for 20 miles
left of course type 20L and for 35 miles right of course type 35R. Now select the
amount into the OFFSET prompt on LSK 2L. You can see the anticipated new
offset course on the ND. If you wish to adjust it press ERASE and type in the
new amount. Once satisfied with the new course press INSERT. Aircraft will take
a 45° cut to the new course. To resume the original course access the same
OFFSET prompt and clear or go DIRECT to a fix on the original flight plan.

New SID: Press the LSK 1L key for the departure airport. Now select
DEPARTURE, then select the departure runway. If you are using a SID select
the appropriate SID (NOTE: you may have to scroll to see all available SIDS). If
there is a transition to the SID you can select it on the right side of the MCDU.
Once everything is selected press INSERT.
