Calculating true airspeed and density altitude:
1)
From the
Main Menu
, touch
Tools
>
E6B Calc
, enter the altitude shown
on the altimeter into the ‘Indicated Altitude’ datafield.
2)
Repeat for ‘Calibrated Airspeed’, ‘Baro Pressure’, and ‘Total Air
Temperature’ datafields. (For Calibrated Airspeed, use the speed shown on
the airspeed indicator. Use the current altimeter setting for Baro Pressure.
Total Air Temperature is the temperature of the outside air including the
heating effect caused by speed. For most aircraft, this is the temperature
reading on a standard outside air temperature gauge.) The calculated
figures for True Airspeed and Density Altitude are shown in the designated
fields.
Calculating winds aloft:
1)
From the
Main Menu
, touch
Tools
>
E6B Calc
, calculate or enter the true
airspeed into the ‘True Airspeed’ datafield.
2)
Enter the aircraft heading shown on the directional gyro or compass
into the ‘Heading’ datafield. Tail Wind, Wind From, and Wind Speed are
calculated.
NOTE: If True North is selected as the heading reference, a heading referenced
to True North must be used to calculate winds accurately.

AIRCRAFT PROFILE
The Aircraft Profile allows the pilot to select cruising speed, maximum speed, fuel
flow, and map symbol. The unit can save up to 10 aircraft profiles.
The maximum speed is used to define the range for airspeed on the Panel and is
automatically updated if you exceed this figure.
Accessing the aircraft profile:
From the Main Menu , touch Tools > Profile
