FLIGHT INSTRUMENTS
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 setting creates discontinuities in VNV
vertical deviation, 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.
Selecting the Altimeter barometric setting:
Turn the BARO (outer) Knob to select the desired setting.
Selecting standard barometric pressure (29.92 in Hg):
1) Press the PFD Softkey.
2) Press the STD BARO Softkey.
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; see Figure 2-11).
4) Press the BACK Softkey to return to the top-level softkeys.
VERTICAL SPEED INDICATOR (VSI)
The Vertical Speed Indicator (VSI, Figure 2-12) displays the aircraft vertical speed using a non-moving tape
labeled at 1000 and 2000 fpm with minor tick marks every 500 fpm. The current vertical speed is displayed
in the pointer along the tape. Digits appear in the pointer when the climb or descent rate is greater than 100
fpm. If the rate of ascent/descent exceeds 2000 fpm, the pointer appears at the corresponding edge of the tape
and the rate appears inside the pointer.
A magenta chevron bug is displayed as the Required Vertical Speed Indication (RVSI) for reaching a VNV
Target Altitude once the “TOD [Top of Descent] within 1 minute” alert has been generated. See the GPS
Navigation Section for details on VNV features, and refer to Section 2.2, Supplemental Flight Data, for more
information about VNV indications on the PFD.
