4 PT
(Procedure
Turn).
PT
displayed on this line indicates that a holding pattern
entry with an auto exit is programmed at a waypoint.
The FMS will fly the appropriate entry the first time
over the PT waypoint. The next time over the
waypoint, the system will sequence to the following
waypoint on the flight plan.
(c) NX, HDG SELECT, or INTERCEPT
HDG Line.
1 NX. Displays the next waypoint
identifier on the active flight plan in the left field and
the ETA at that waypoint in the right field. This line is
displayed during waypoint alert only.
2 HDG SELECT. HDG SELECT will
be annunciated when heading mode has been
selected but with no intercept. Commanded heading
and turn direction will be annunciated in the right field.
3 INTERCEPT HDG. INTERCEPT
HDG will be annunciated when heading mode has
been selected and will intercept the next leg.
Commanded heading and turn direction will be
annunciated in the right field.
(d) DIS. This line displays the distance
in nautical miles and tenths of miles from the aircraft's
present position to the to waypoint. During waypoint
alert, the distance in whole nautical miles to the next
(NX) waypoint is displayed in parentheses.
(e) ETE.
This
line
displays
the
estimated time en route in hours, minutes, and tenths
of minutes, from the aircraft's present position to the to
waypoint based on current groundspeed.
(f) DTK. This line displays the desired
track (DTK). The DTK is the great circle course in
whole degrees between the FROM and TO waypoints.
When in the PSEUDO VORTAC mode, the desired
track is entered by the crew. During a waypoint alert,
desired track to the next waypoint is displayed in
parentheses.
NOTE
Dashes will be displayed in the DTK field if
the FROM waypoint or present position are
north of N 70° or south of S 60° latitude,
unless a manual magnetic variation (MAG
VAR) is entered or a discrete MAG / TRUE
switch is moved to the TRUE position.
(g) GS. This line displays the current
groundspeed.
(h) WIND. This line displays the current
wind direction referenced to true north, and wind
speed in knots.
(i) AUTO. This line displays the
selected leg change mode. Automatic (AUTO) or
manual (MAN) may be selected by using the BACK
key.
(2) Navigation
1/4
(With
Programmed
Holding Pattern).
(a) HOLD. This line indicates that a
holding pattern has been initiated. RIGHT or LEFT
displayed on the left side of the field indicates the
direction of turns to fly the pattern as entered on the
Hold page. MANUAL or AUTO on the right side of the
field indicates the programmed exit mode as entered
on the Hold page. Selecting manual initiates a
continuous hold at the fix until action is taken by the
crew to exit the hold. Selecting AUTO executes an
exit the second time the aircraft passes over the fix.
The system then sequences to the next waypoint on
the flight plan. This field can be edited by using the
BACK key.
(b) AT. This line displays the identifier of
the holding fix for the holding pattern in use on the left
side, and the ETA of the next time over the holding fix.
This line can also display the following.
1 HP. This line displays the identifier
of the holding fix for which a holding pattern is
programmed in the left field with the ETA at the
holding fix in the right field.
(c) PT. This line displays the identifier of
the holding fix for which a procedure turn is
programmed in the left field with the ETA over the
holding fix in the right field.
(d) AR. This line displays the identifier
of the holding fix for which a DME arc is programmed
in the left field with the ETA over the fix in the right
field.
(e) Holding Status Message.
1 DIRECT ENTRY. This display
message indicates that the system will use a direct
entry into the holding pattern. This message will
appear 30 seconds prior to entering the holding
pattern. The display message will change to
HOLDING after crossing the holding fix.
2 TEARDROP ENTRY. This display
message indicates that the system will use a teardrop
entry into the holding pattern. This message will
