STEP 2: Use the small and large right knobs
to enter the indicated altitude.
STEP 5: Use the small and large right knobs
to enter the total air temperature (TAT). TAT is the
temperature, including the heating effect of speed,
read on an outside temperature gauge.
Flight Planning
Flight Planning Page: Density Alt / TAS / Winds
To calculate density altitude, true airspeed, winds aloft:
1. Select “Density Alt / TAS / Winds” from the Flight Planning page, using the steps described on page 114.
2. The flashing cursor highlights the indicated altitude (IND ALT) field. Use the small and large right knobs
to enter the altitude indicated on your altimeter. Press ENT when finished.
3. The flashing cursor moves to the calibrated airspeed (CAS) field. Use the small and large right knobs to
enter the airspeed from your airspeed indicator. Press ENT when finished.
4. The flashing cursor moves to the barometric pressure (BARO) field. Use the small and large right knobs
to enter the barometric pressure (altimeter setting). Press ENT when finished.
5. The flashing cursor moves to the total air temperature (TAT) field. Use the small and large right knobs to
enter the temperature. Press ENT when finished.
6. The flashing cursor moves to the aircraft heading (HDG) field. Use the small and large right knobs to
enter the aircraft heading from the directional gyro or compass. Press ENT when finished.
7. With all variables entered, the following information is provided:
• DEN ALT—Density altitude
• TAS—True airspeed
• WIND—Wind direction and speed
• HEAD/TAIL WIND—Magnitude of head wind or tail wind component
NOTE: If your installation includes components (such as an air/data sensor) to provide any of
the variables above, the Density Alt / TAS / Winds page data default to the values provided by
these components.
