The Distance/Time 4 Page (D/T 4) - Honeywell KLN 900s Pilot's Manual

4.2.9 The Distance/Time 4 Page (D/T 4)

The format of the D/T 4 page does not change. It dis-
plays on a single page the pertinent times for the flight
regardless of what is displayed on the left page and
regardless of whether flight plan or Direct To operation is
occurring (figure 4-53). The information displayed on the
D/T 4 page is the following:
• The destination waypoint.
• The selected time zone. The time zone may be
changed by pressing the right C and using the right
inner knob to select the desired time zone.
• DEP - The departure time. There are two definitions of
departure time depending on what has been selected
on the Setup 4 page (SET 4 - see figure 4-54). If the
SET 4 page
GS > 30KT, then the departure time is that time when
the groundspeed first reached 30 knots. If instead,
the SET 4 page displays RUN WHEN POWER IS ON,
then the departure time is the time when power was
applied to the KLN 900. The SET 4 page may be
changed by pressing the left C while the SET 4
page is displayed on the left side and then rotating the
left inner knob. Press the left C again to turn the left
cursor function off.
• TIME - The present time. The time may be reset on
the Self Test page at system turn-on or on the SET 2
page.
• ETA - The estimated time of arrival at the destination
waypoint.
• FLT - The flight time. If RUN WHEN GS > 30 KT is
selected on the SET 4 page, then flight time is the
amount of time that the aircraft's groundspeed has
been above 30 knots. Normally, this will be the time
since takeoff. However, time spent at ground speeds
less than 30 knots such as intermediate stops without
shutting down power or helicopter hovering is not
counted as flight time.
If the present position flags (NAV flag) after being valid
in the NAV mode, the flight timer continues to run if
the groundspeed was more than 30 knots immediately
before the flag.
If RUN WHEN POWER IS ON is selected on the SET
4 page, then flight time is the time since power on.
• ETE - Estimated time enroute to the destination
waypoint.
