dAlT/TAS/Winds

Density Alt / TAS / Winds — indicates the theoretical altitude at which
your aircraft performs depending upon several variables, including indi-
cated altitude (Indicated ALT), barometric pressure (BARO) and total air
temperature (TAT; the temperature, including the heating effect of speed,
read on a standard outside temperature gauge). This item computes true
airspeed (TAS) and density altitude, based upon the factors above. Also,
this feature determines winds aloft — the wind direction and speed — and
a head wind/tail wind component, based on true airspeed, aircraft heading
(HDG) and ground speed.
