6. Press the
A button again to
move on to the ALT 2 page (fig-
ure 5-17). Only line 2 of the
ALT 2 page is used for altitude
alerting. The remainder of the
ALT 2 page is used only for ver-
tical navigation, or VNAV. The
first altitude displayed on line 2 is the current indicated altitude (9000
feet in figure 5-17). With the proper altimeter baro setting, the indicat-
ed altitude should be the same as the aircraft’s actual altimeter.
NOTE: There may be some difference (less than 100 feet) between the
indicated altitude and the aircraft’s actual altitude if the altitude input to the
KLN 94 is from an altitude encoder because these encoders only provide
altitude in 100 foot increments.
7. The cursor should be positioned
on the selected (or to) altitude
field (figure 5-17). Enter the
selected altitude using the right
inner knob (figure 5-18).
8. Press A to return to the page which was previously displayed.
Notice that when you are on an ordinary (non-altitude) page, the first
press of the
A button brings up the ALT 1 page, the second press of
A brings up the ALT 2 page, and the third press takes you back to
the original page.
9. The aural alarm activates as follows:
• 1000 feet prior to reaching the selected altitude—three short
tones
• Upon reaching the selected altitude—two short tones
• Deviating above or below the selected altitude by more than the
warn altitude—four short tones
NOTE: Due to the resolution of the altitude input, it may be necessary to
descend slightly below or climb slightly above the selected altitude before
the two tones are activated indicating that the selected altitude has been
reached. This selected altitude alert must be activated to arm the system
for providing the altitude deviation alert.
The KLN 94 can provide the aural alarm tones in either of two ways: it
may be connected to an audio input of an audio amplifier contained in an
audio panel so that the aural alarm is heard through the aircraft’s speaker
