3.12. ALTITUDE PAGES
The ALT (altitude) pages are used to control and display most of the
altitude-related functions of the KLN 89(B), including minimum safe alti-
tudes and vertical navigation (VNAV). The ALT pages are accessed
by pressing the
A
button. The first time the
A
button is pressed,
the ALT 1 page is displayed (figure 3-169). If the
A
button is pressed
again while the ALT 1 page is dis-
played, the display changes to the ALT
2 page. Pressing
A
a third time
goes back to the page which you were
on before you changed to the ALT
pages.
NOTE: For a detailed discussion of the ALT 2 page, see
“Advisory VNAV Operation”.
The ALT 1 page is used to set the current barometric pressure or “baro
setting”. Since all encoding altimeters and some air data computers
output pressure altitude, it is often required that you manually input the
proper baro setting in order to get accurate altitude functions. The KLN
89(B) functions which use the altitude input are special use airspace
(SUA) alerting, altitude alerting, and vertical navigation (VNAV). It is a
good idea to update the altimeter baro setting on the ALT 1 page each
time you make a change to the aircraft’s altimeter setting.
To Change the Baro Setting:
1.
Press
A
. The ALT 1 page will be displayed with the cursor over
the altimeter baro setting field (figure 3-169).
NOTE: The SET 8 page (figure 3-170)
is used to set the unit of measure for
various parameters. The altimeter
barometric setting can be set to inches
of Mercury (“), millibars (mB), or hec-
topascals (hP). Altitude, airport
elevation, and runway lengths can be
set to feet (ft) or meters (m). Finally,
distances and velocities can be set to nautical miles (nm) and knots (kt)
or kilometers (km) and kilometers/hour (k/h). To change a unit of mea-
sure: select the SET 8 page; turn on the cursor (CRSR) and move it
over the desired unit of measure using the right outer knob; turn the
right inner knob to select the desired unit of measure; and turn the cur-
sor off again. This format for the SET 8 page applies to ORS 02
software. ORS 01 software only allows the selection of barometric set-
ting units.
