FLIGHT INSTRUMENTS
Altitudes can also be displayed in meters (Figure 2-8). Note that the altitude tape does not change scale when
the metric altitude overlay is enabled.
Displaying altitude in meters:
1) Press the PFD Softkey to display the second-level softkeys.
2) Press the ALT UNIT Softkey.
3) Press the METERS Softkey to turn on metric altitude readouts.
4) Press the BACK Softkey to return to the top-level softkeys.
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 patch. 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.
Selecting the altimeter barometric pressure setting:
Turn the BARO Knob to select the desired setting.
Selecting standard barometric pressure (29.92 in Hg):
1) Press the PFD Softkey to display the second-level softkeys..
2) Press the STD BARO Softkey; STD BARO is displayed in barometric setting box.
Changing altimeter barometric pressure setting units:
1) Press the PFD Softkey to display the second-level softkeys.
2) Press the ALT UNIT Softkey.
3) Press the IN Softkey to display the barometric pressure setting in inches of mercury (in Hg).
Or , press the HPA Softkey to display the barometric pressure setting in hectopascals (hPa).
4) Press the BACK Softkey to return to the top-level softkeys.
