UNITS AND UNIT OVERLAYS
The pilot can choose to display overlays for the Indicated Altitude and Selected Altitude using alternate
display units without changing the scale of the Altimeter. For example, if the Altimeter is displaying feet,
the system can show a metric overlay for the indicated and selected altitudes without changing the scale or
display units of the Altimeter.
Displaying the metric altitude overlays:
1)
Press the
PFD
Softkey to display the second-level softkeys.
2)
Press the
ALT
UNIT
Softkey.
3)
Press the
METERS
Softkey to enable/disable metric altitude overlays.
4)
Press the
BACK
Softkey twice to return to the top-level softkeys.
BAROMETRIC SETTING
The barometric pressure setting is displayed below the Altimeter in inches of mercury (in Hg), or
hectopascals (hPa) when metric units are selected. Adjusting the altimeter barometric pressure setting creates
discontinuities in VNV vertical navigation, moving the descent path. For large adjustments, it may take
several minutes for the aircraft to re-establish on the descent path. If the change is made while nearing a
waypoint with a VNV Target Altitude, the aircraft may not re-establish on the descent path in time to meet
the vertical constraint.
