System Description
Pilot Settings
1.19 Display Brightness Control
1.19.1 Automatic Brightness Control
Dimming is limited to prevent on screen indications from becoming unreadable. The
built in photocell automatically controls display brightness based on ambient light
levels.
1.19.2 Manual Brightness Control
Optionally, the TXi system is configurable to use an aircraft dimming bus for display
brightness control. Upon reaching minimum input level, display brightness reverts to
the photocell. This prevents the display from going black in the event of a dimmer
input failure.
Turboprop Aircraft
Depending on installation, display
brightness control may transition
between lighting bus and
photocell during engine start.
When you engage the start
switch, display brightness control
switches to photocell. When you
disengage the switch, or after
60 seconds, brightness control
returns to the dimmer bus.
If brightness control is not
satisfactory, contact a Garmin
dealer to adjust the lighting curves.
Depending on configuration, display
brightness is controlled using inputs from
the built in photocell, aircraft dimmer
bus, or both. Installer configured curves
determine the amount of change in
brightness that occurs in response to a
control adjustment
