Aviation Utilities
To help you with flight planning, this unit has four aviation utilities
built into it that let you calculate density altitude, true airspeed, wind
speed and direction, plus vertical navigation.
NOTE:
AirMap also includes a set of five general-purpose utilities. These
are discussed in Sec. 4, Utilities.

ALTITUDE), barometric pressure
(
BARO) in inches of mercury, outside air temperature (TEMP), and cali-
brated airspeed (
CAS).
