TemperatureCompensationofApproachMinimums
To enable temperature compensation of the minimum altitude, a new option, “TEMP COMP”, has been
added when selecting the minimum altitude reference type (in addition to “OFF”, “BARO”, and “RAD
ALT”). The temperature at the destination airport is used for this purpose. The compensated value is
displayed below the entered, uncompensated value (Figure 27). If a temperature has been entered for
compensating waypoint altitudes on the active flight plan page, it is used as the default here, and
vice-versa. Similar functionality exists in the minimums selection field on the approach selection pages
(Figure 28).
The temperature at the destination airport is invalidated when a different approach is loaded into the
active flight plan or when the system powers up. This disables temperature compensation of both the
published approach waypoint altitudes on the active flight plan page and the minimum altitude. The
minimum altitude selection type changes to “BARO” if it was previously set to “TEMP COMP”.
Temperature compensation of the minimum altitude is not dependent on use of barometric altitude for
vertical guidance on the FAS, and is therefore available for any type of approach; in fact, only the
destination airport and temperature are required. Compensating the approach minimums bug simply
determines where the minimums reference is displayed on the altimeter. No adjustment to the
barometric altitude is made as a result of temperature compensating the minimums reference.
