7.9.2 INTERIOR LIGHTNING
Instrument Lights
Mechanical instruments, Airspeed Indicator and Altimeter are TSO’d and
internally illuminated. Other instrumentation has backlit dimmable LCD dis-
plays and illuminated buttons.
Panel Flood Lights
A cabin flood-light is present and provides illumination to master electrical
panel and circuit breakers. Fuel level indicator tubes are lighted individually
with dedicated LED elements and are controlled on demand with a labeled
switch on the instrument panel.
Dimming
Intensity of all displays’ illumination is synchronized and controlled by the
SmartDim controller, either reacting to ambient light conditions automatical-
ly or as manually set by the pilot. Rotating the knob to the right will result
in brigher illumination, rotating the knob to the left will result in dimming.
Pressing the knob for 2 seconds will engage automatic illumination which
reacts to ambient light conditions using a built-in light sensor. Corresponding
SmartDim display indications are provided.
7.10 ENVIRONMENTAL SYSTEM
There are two separate systems that account for cabin ventilation and heat-
ing: the cabin passive inlets/outlets for fresh air routing and the cabin heat
system.
Cabin passive ventilation
The system’s primary source of fresh air is a set of sliding windows and ad-
justable vents that direct fresh ram air into the cabin. There is a sliding win-
dow door on the starboard side, an adjustable circular vent in the door on
the port side and another adjustable circular outlet in the sun roof.
