Minimum Altitude Display and Alerting

When enabled by the pilot, an altitude minimums bug will be displayed in cyan on the barometric
altitude tape.
Altitude minimums are accessed under the PFD Options Menu  Minimums sub menu and can be
set by touchscreen keypad or dual-concentric knob.
Both visual and aural altitude minimums alerts are provided. During a descent to minimums, the
minimums bug will change from cyan to white when the aircraft descends to within 100 ft of minimums.
An aural "Minimums, Minimums" alert will be triggered when the aircraft's altitude descends through
minimums and the minimums bug will change to Amber. As the aircraft altitude climbs back above
minimums, the minimums bug will change to white 50 ft above minimums and cyan 150 ft above
minimums. Alerting is rearmed once the aircraft is 150 ft or more above the minimum's altitude.
If a new approach is loaded into the external navigator, the Minimums Altitude display is not
automatically updated with the new approach minimums. The pilot must update the Minimums Altitude
Display with the MDA/DH for the approach loaded into the navigator.

7.10 AOA Probe

The G3X Touch PFD will display angle of attack from the GAP 26 AOA probe if installed. The GSU 25
uses the pressure from the GAP 26 probe and the pitot/static pressures it already receives from the
existing aircraft pitot/static system to determine the aircraft's angle of attack (AOA).
The AOA indications and warnings presented on the G3X system are for reference only and are not
intended as replacements for the aircraft's original stall warning system. The AOA stall warning margin
and indications may not be the same at different flap settings and are only supported for positive G
flight.

7.11 GAD 27 Wig Wag

The GAD 27 module (if installed) provides a feature that provides the ability to flash the Landing and
Taxi lights of the airplane in an alternating fashion, otherwise known as "Wig Wag". Two 3-position
switches control this feature, one for the landing lights and one for the taxi lights:
ON – Respective light is on
•
• FLASH – Respective light will flash
OFF – Respective light is off
•
