5.3 CALCULATOR PAGES
There are seven Calculator pages which may be used to
calculate a variety of flight related information such as
pressure and density altitude, true airspeed, winds aloft,
VNAV angle, and time zone conversions. The Calculator
pages allow you to make “what if” calculations for condi-
tions other than the present situation. Therefore, the
Calculator pages rely on you to make manual inputs of air
data parameters such as altitude and true airspeed even
if the KLN 900 is interfaced to air data sensors. If the
KLN 900 is interfaced with a compatible air data system,
the Other 9 and Other 10 (OTH 9 and OTH 10) pages
display the air data information directly.
5.3.1 The Calculator 1 Page (CAL 1)
The CAL 1 page is used to determine pressure altitude
and density altitude. To calculate these values:
1. Display the CAL 1 page on the left side (figure 5-29).
2. Press the left C to turn on the left cursor function.
3. Enter the altitude indicated on the aircraft’s altimeter
(IND) to the nearest hundred feet or ten meter by
using the left outer knob to move the cursor to the
desired position and the left inner knob to select each
digit (figure 5-30).
4. Use the left outer knob to move the cursor to the first
BARO position, and then enter the current altimeter
setting by using the left inner and outer knobs (figure
5-31). The pressure altitude is now displayed (PRS).
NOTE: The SET 7 page (figure 5-32) is used to set the
unit of measure for various parameters. The altimeter
barometric setting can be set to inches of mercury (“), mil-
libars (mB) or hectoPascals (hP). Altitude, airport eleva-
tion, and runway lengths can be set to feet (ft) or meters
(m). Finally, distances and velocities can be set to nauti-
cal miles (nm) and knots (kt) or kilometers (km) and kilo-
meters/hour (k/h). To change a unit of measure: select
the SET 7 page; turn on the left
C and move it over the
desired field using the outer knob; turn the left inner knob
to select the desired unit of measure; and turn the cursor
off again. This format for the SET 7 page applies to ORS
02 or later software. ORS 01 software only allows the
selection of barometric setting units.
NOTE: Some areas of the world use hectopascals as a
barometric unit. Hectopascals are numerically the same
as millibars so choose millibars as the barometric unit in
these areas.
5. Use the left outer knob to move the cursor to the first
TEMP position, and then enter the outside air temper-
ature (degrees C) by using the left inner and outer
knobs (figure 5-33). The first digit of the temperature
is either “0” if the temperature is above zero or “-” if
the temperature is below zero. For maximum accu-
