Pitch Offset–Allows the pitch offset to be Disabled or User Selected (default). When disabled, the pitch
offset is not able to be changed as a user setting.
Roll Display–Allows setting the Roll Display to either Ground Pointer or Sky Pointer.The Ground Pointer
configuration displays both the roll arc and the pitch ladder anchored to the horizon and the roll pointer
beneath the roll arc pointing to the present roll angle. The Sky Pointer configuration displays the pitch
ladder moving with the horizon, but the roll arc remains fixed and centered in the display. The roll pointer
beneath the roll arc moves with the horizon and in the opposite direction of aircraft roll.

Vertical Speed Indicator Range–Allows the range of the vertical speed tape to set to +/- 2,000 fpm,
+/- 3,000 fpm, or +/- 4,000 fpm.
HSI Orientation–Allows setting the PFD HSI Orientation to either Heading or User Selected (default).
The Heading selection displays the HSI (on the PFD) in a heading-up orientation. The User Selected
setting enables an HSI Orientation option on the PFD Setup page, see the G3X Touch Pilot’s Guide
(190-0174-00) for more info.
Trim/Flap Position Display–Allows installer to hide or show trim and flap indications on the PFD. If set
to User Selected, the pilot can toggle these indications on and off in normal mode.
Miscompare Monitoring (see Figure 30-56
)– Selecting ADAHRS + SFD will enable Miscompare
(differences in heading, attitude, airspeed, etc.) Monitoring between an SFD (Standby Flight Display,
consisting of one or more G5 units) and an ADAHRS LRU (GSU 25 or GSU 73).
In a system with a single ADAHRS LRU, selecting ADAHRS + SFD will enable the system to constantly
perform Miscompare Monitoring between the standby flight display and the ADAHRS. In a system with
multiple ADAHRS LRUs, selecting ADAHRS + SFD will enable the system to perform Miscompare
Monitoring only if the system performance degrades to the equivalent of a single ADAHRS (due to the
loss of all other ADAHRS LRUs).
When an miscompare condition between SFD and ADAHRS is detected, a CAS message will be displayed
characterizing the miscompare condition. If an attitude miscompare is detected, ESP will be inhibited and
the CAS message "ESP INHIBIT" will be displayed. The autopilot will remain usable during this
condition.
