Temperature Reference

The computer calculates the temperature based on temperature probe and
Pitot-static inputs. The units (°C or °F) and temperature reference are selected
on the AUX – SYSTEM SETUP page. The temperature reference can be selected
to one of the following choices:
• Static Air Temperature (SAT) – This is the calculated temperature of the
stationary (static) outside air. Conceptually, this is the temperature that
would be read on a thermometer floating stationary at the current location.
• Total Air Temperature (TAT) – This is the calculated temperature of the
outside air as it moves past the aircraft, including the rise in temperature
due to air compression and friction at the current airspeed.
• Difference from International Standard Atmosphere (ISA) – This is the
difference between SAT and standard (ISA) temperature at the current
altitude. This provides an indication of how much warmer/colder the
temperature is from a "standard" atmosphere.
