Temperature Compensated Altitude
NOTE:
GTNs and TXi displays use only one destination airport temperature
for calculating compensated altitudes. Changing the temperature on one
of these units automatically recalculates the value across all connected
GTNs and GDUs.
A temperature compensation function calculates loaded approach altitudes
based on the pilot-specified destination temperature. Once the pilot enters a
destination temperature, the system increases the approach altitudes accordingly.
