SET 4 page displays RUN WHEN POWER IS ON, then the departure
time is the time when power was applied to the KLN 90B. 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 at any time.
• 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 ground-
speed has been above 30 knots. Normally, this will be the time since
takeoff. However, time spent at groundspeeds less than 30 knots such
as intermediate stops without shutting down power or helicopter hov-
ering is not counted as flight time. 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.
14.0 ALTITUDE ALERTING
If your aircraft does not already have an altitude alerting capability you
may wish to use the KLN 90B’s capability of assisting you with altitude
management during your flying. Altitude alerting allows you to select a
target altitude and it then provides you with an aural alarm 1000 feet prior
to reaching the selected altitude, another aural alarm upon reaching the
selected altitude, and another aural alarm if you deviate from the selected
altitude.
To use altitude alerting:
1. Press A. The Altitude page will be displayed on the left with the cursor
over the first two digits of the altimeter baro set field. The NAV 4 page
will be displayed on the right with the cursor over the first digit of the
selected altitude field .
NOTE: The units of the altimeter baro set may be changed on the SET 7
page.
2. Use the left knobs to update the altimeter baro setting if required. There
are three cursor positions. Use the left outer knob to move the cursor
and the left inner knob to change digits. With the proper altimeter baro
setting, the indicated altitude (IND) on the right should be the same of
the aircraft’s actual altimeter.
