FLIGHT MANAGEMENT
TEMPERATURE COMPENSATED ALTITUDE
If desired, the system can compensate the loaded approach altitudes based on a pilot-supplied temperature
at the destination. For example, if the pilot enters a destination temperature of -40º C, the system increases
the approach altitudes accordingly. A temperature compensated altitude is displayed in slanted text.
Activating temperature compensated altitude:
1) From the Active Flight Plan Page, press the MENU Key. The Page Menu is displayed.
2) Turn the FMS Knob to highlight 'Temperature Compensation'.
3) Press the ENT Key. The Temperature Compensation Window is displayed.
4) Use the small FMS Knob to select the temperature at the <airport>. The compensated altitude is computed as
the temperature is selected.
The temperature at the destination can be entered in the Temperature Compensation Window on the
NOTE:
MFD, or in the References Window on the PFD. There is only one compensation temperature for the system,
therefore, changing the temperature will affect both the loaded approach altitudes and the minimums.
Refer to the Flight Instruments section for information about applying temperature compensation to the
MDA/DH.
5) Press the ENT Key. 'Activate Compensation?' is highlighted.
6) Press the ENT Key. The compensated altitudes for the approach are shown in the flight plan.
