insertion at the revised waypoint.
DATABASE HOLD AT...
If a hold is defined in the navigation database for the revised waypoint, and if this hold has not
been inserted yet, an arrow is displayed in the [2R] field next to DATABASE.
Then the flight crew can insert this hold in the temporary flight plan by pressing the [2R] key.

COMPUTED HOLD
If a default hold is computed by the FMS, and this hold has not been inserted yet, an arrow is
displayed in the [1R] field next to COMPUTED. Then the flight crew can insert this hold in the
temporary flight plan by pressing the [1R] key.
A computer hold has the following default parameters :
INB CRS = INBD TRK of the F-PLN leg leading to the revised waypoint.
TURN = Turn direction right.
TIME on outbound leg is 1.5 min above 14 000 ft, 1 min below 14 000 ft.
[ 1L ] INB CRS This field displays the inbound course of the holding pattern. The
data may be manually or automatically modified (via COMPUTED or
DATABASE prompts).
[ 2L ] TURN This field shows the direction to turn in the hold (L or R). The data
may be modified.

[ 3L ] TIME/DIST This field shows the time and distance for the outbound leg. The
data may be modified, but time and distance cannot be entered
simultaneously.
Time and distance are dependent values that the system calculates
from the predicted ground speed at the revised point, which in turn
depends upon the holding speed (speed for maximum endurance,
ICAO speed limit, or constraint speed, whichever is lower).

RETURN
This prompt gives access to the temporary flight plan page if one is in
progress.
If not, “RETURN” is displayed and allows a return to the LAT REV
page.
[ 1R ] COMPUTED (→) Pressing this key reverts parameters to the system-computed
parameters (1L, 2L, 3L).
[ 2R ] DATABASE (→) Pressing this key reverts the displayed parameters to the parameters
memorized in the database for this waypoint.
LAST EXIT UTC FUEL This field displays the time at which the aircraft must leave the
holding pattern in order to meet fuel policy criteria (extra fuel = 0). The
system also displays the estimated fuel on board at that time.
The 1R and 2R fields, as well as the hold parameters (1L, 2L, 3L), are blue when no temporary
flight plan exists, and yellow when a temporary flight plan is in progress.
DIRECT TO PAGE
Applicable to:
,
,
MSN,,
4538,,
Pressing the “DIR” key from the MCDU screen calls up the DIR TO page. 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 invalid. The “A/C
POSITION INVALID” message is then displayed.
These are four DIRECT TO/INTERCEPT functions : DIRECT TO, ABEAM PTS, RADIAL IN, RADIAL
OUT.
Using the DIRECT TO function results in the creation of a temporary F-PLN.

[ 1L ] WAYPOINT This field gives access to the ’Direct To’ fix waypoint to be selected
from a list of waypoints. The ’Direct To’ waypoint may be entered by
using its identifier, place/bearing/distance, place-bearing/ place-bearing
or latitude/longitude.
[ 2L ] to [ 5L ] F-PLN WPTS This list provides the waypoints of the active flight plan, except
waypoints from the missed approach, pseudo-waypoints F-PLN
markers, non fixed waypoints.
The display may be scrolled ↑↓
If a temporary flight plan exists, all the waypoints from the list are not
selectable.
[ 6L ] DIR TO ERASE Pressing this key deletes the temporary F-PLN.
[ 1R ] UTC/DIST As soon as the temporary F-PLN is created, the time and distance to
the ’Direct to’ fix waypoint is displayed in yellow.
