IFD400 Series Pilot Guide
Aux Subsystem 4-11
CALCULATORS
Several calculators are included in the system and all can be
accessed via the “Calculators” LSK on the UTIL tab of the AUX
page.
TIPS AND TECHNIQUES
Pre-Populated Data Fields
Many data fields in the various IFD calculators will
be populated automatically with sensor data in green
if it is available, or can be manually edited/entered
by the pilot. The DEST field will be populated with
the last airport in the active flight plan, not
necessarily the last waypoint in that flight plan. Non-
airport waypoints are not permitted in the DEST
field.
If a pre-populated field had been manually altered, the sensor
supplied data can be restored by pressing the CLR button on the
bezel.
