4) Select 'REVERT' and press the ENT Key. The altitude is changed to the navigation database value.
5) Push the FMS Knob to remove the flashing cursor.
QFE CONSTRAINTS
Baro QFE settings may be enabled so the altimeter will read zero at the selected reference point (Origin
or Destination airfield), and terminal altitude constraints in the flight plan are displayed as the height above
the reference point. When Baro QFE is enabled, altitude constraints based on Baro QFE may be entered or
modified in the flight plan and will be displayed in parenthesis. See the Flight Instruments Section for more
information on how to enable Baro QFE.
WARNING: Do not fly QFE procedures above the Transition Altitude or when navigating to a waypoint that
contains a QNE (flight level) altitude constraint.
WARNING: Always fly a procedure that provides terrain and obstacle clearance from the reference airfield
when operating in IMC while conducting QFE procedures.
Entering or modifying a Baro QFE altitude constraint:
1) With Baro QFE enabled, press the FPL Key for the MFD to display the 'FPL – Active Flight Plan' Page.
2) Push the FMS Knob, and turn the large FMS Knob to highlight the desired waypoint altitude constraint ('ALT').
3) Turn the small FMS Knob to begin entry of the altitude constraint, and use the FMS Knobs to enter the
constraint in reference to Baro QFE. If modifying an existing Baro QFE altitude constraint, turning the small FMS
Knob displays the existing constraint in MSL in the entry field. If adding a new altitude constraint, turning the
small FMS Knob displays '00000FT' in the entry field.
4) Press the ENT Key. Turn the small FMS Knob to highlight 'QFE' and press the ENT Key to accept the altitude
constraint. The constraint is shown in parenthesis indicating it is based on the Baro QFE setting.
