DALT/TAS/Wind Statistics

Compute and display density altitude and current wind conditions. Calculations are
based on current input values.
This information is for planning purposes only.
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. Total air temperature includes temperature and the heating effect of speed, as
read on a standard outside temperature gauge.
Wind data calculations are dependent on aircraft heading and track, true airspeed, and ground speed.
Wind direction is dependent on the NAV Angle system unit setting.
If wind speed is zero, wind direction displays as dashes.
