Temperature Compensated Altitude - Garmin GTN 750 Pilot's Manual Upgrade Supplement

4.3.4

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.
4.3.4.1 Temperature Compensation Requirements
