Computing DALT/TAS/Wind Statistics

Density Altitude
•
Pressure altitude corrected for
nonstandard temperature
•
Units display in increments of ten
Density altitude and true airspeed calculations are dependent on indicated altitude, barometric pressure,
and total air temperature.
Wind data calculations are dependent on true airspeed, aircraft heading, and ground speed.
Wind direction is dependent on the NAV Angle system unit setting.
If wind speed is zero, wind direction displays as dashes.
4-10
Compute and display density altitude and current wind
conditions. Calculations are based on current input values.
