Alerting is inhibited while the aircraft is on the ground and until the aircraft reaches 150 feet above the MDA.
If the aircraft proceeds to climb after having reached the MDA, once it reaches 50 feet above the MDA, alerting
is disabled. The function is reset when the power is cycled or a new approach is activated.
Setting the barometric minimum descent altitude and bug:
1) Press the TMR/REF Softkey.
2) Turn the large FMS Knob to highlight the Minimums field.
3) Turn the small FMS Knob to select the barometric (BARO) or temperature compensated (TEMP COMP) barometric
altitude. OFF is selected by default. Press the ENT Key or turn the large FMS Knob to highlight the next field.
4) Use the small FMS Knob to enter the desired altitude (BARO or TEMP COMP from zero to 16,000 feet). If TEMP
COMP is selected, a field for entering the temperature at the destination will appear. Press the ENT Key or turn
the large FMS Knob to highlight this field, and use the small FMS Knob to enter the temperature (from -59º C
to +59º C.) The system increases or decreases the displayed MDA/DH altitude based on this temperature.
5) To remove the window, press the CLR Key or press the TMR/REF Softkey.

NOTE: The temperature at the destination can be entered in the References Window on the PFD, or Temperature
Compensation Window on the MFD. 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 Management section for information about applying temperature compensation to approach
altitudes.
