key is the DIR TO key. The pilot presses it to modify the flight plan by creating a direct leg from the
aircraft's present position to any selected waypoint. When in NAV mode, the pilot must use this key
to modify the active leg or the TO waypoint. The pilot cannot call up this page when the aircraft's
present position is not valid.
[ 1L ] DIR TO Pressing this key selects the DIRECT TO or INTERCEPT waypoint.
The pilot can identify the waypoint to be inserted by using its identifier, its latitude and longitude,
place/bearing/distance, or place-bearing/place-bearing.
Note: If the entered DIR TO is a latitude/longitude, the NEW WAYPOINT page is
automatically called up.
If the pilot does not select the RADIAL IN (1R) or RADIAL OUT (2R) or ABEAM PTS (2L), the
DIR TO function routes the aircraft from the present position to the waypoint inserted in the
DIR TO field.
Line 3 to
Line 6
These lines display the active flight plan with time/speed/distance predictions. The display may
be slewed ↑↓.
Pressing any key activates the DIRECT TO function from the present position to the waypoint
adjacent to that key.
[ 2L ] ABEAM PTS The flight crew presses this key to activate the DIR TO/ABEAM
function which projects the flight plan waypoints perpendiculary on the DIR TO leg :
EXAMPLE : DIR TO BEROK - ABEAM.

[ 1R ] RADIAL IN
and
[ 2R ] RADIAL OUT
The pilot fills in these fields to define a radial, associated to the waypoint defined in 1L. These
keys respectively activate the DIRTO/INTERCEPT TO and DIRTO/INTERCEPT FROM
functions. The pilot enters the radial in, or radial out, as : XXX, XXX being the radial.
The aircraft intercepts from its current position and tracks the selected waypoint and radial to
(or from) this waypoint.
EXAMPLE : RADIAL INBND - DIR TO BEROK - RADIAL 270 ° INBOUND
If the DIR TO/INTCPT WPT entry is to a waypoint already in the flight plan, a default RADIAL IN is
displayed in small font. However, no radial is displayed on the ND for this default radial. No default
radial is provided for the RADIAL OUT field.
Selecting the INTCPT TO (RADIAL IN [ 1R ]) function :
Activates ‐ the intercept radial INTO the WPT.
‐ Sets the course = radial IN + 180 °.
‐ Reverts the display to the F-PLN A page.
Selecting the INTCPT FROM (RADIAL OUT [ 2R ]) function :
‐ Activates the intercept radial FROM the WPT.
‐ Sets the course = radial OUT.
‐ Reverts the display to F-PLN A page.

ARRIVAL PAGES
Applicable to:
These pages enable the pilot to review arrival procedures (approaches, VIAs, STARs, TRANS) and
enter them into the active flight plan.
The pilot calls them up from the LAT REV page for the destination by the pressing the 1R key.
Three pages, APPR, STAR, and VIA, are available, along with a fourth,TRANS, if there are any
transitions.

The pilot calls up each page sequentially, either by selecting a data item (such as APPR), or by
pressing the NEXT PAGE key on the MCDU console.
Line [ 1L ] - [ 1R ]
[ 2R ]
This line displays the APPR, VIA, STAR, and TRANS in green, if they have been inserted in
the flight plan, and in yellow, as a temporary flight plan, if they have been selected but not yet
inserted.
It displays dashes or NONE, if nothing has been selected or inserted.
[ 2L ] APPR VIAS The pilot presses this key to call up transitions from the last point of the STAR to the first point
of the approach.
[ 3L ]
to
[ 5L ]
These fields list selectable and selected APPRs, STARs, and VIAs. The flight crew can slew
the pages, when necessary. Selectable APPRs, STARs, and VIAs are displayed in blue with
an arrow.
Once the pilot has selected an APPR, STAR, or VIA, the arrow disappears. After the APPR,
STAR, or VIA is inserted into the flight plan, it is displayed in green.
For each approach, the display shows runway length, heading, and the frequency and
identifier of the ILS when ILS is available.
[ 6L ] ERASE
or RETURN
The pilot presses this key to erase selected data and to revert to the previous selection. The
page reverts to the LAT REV page.
