SR22 Airplane Description

Interior Lighting

Interior lighting for the airplane consists of separately controlled
incandescent overhead lights for general cabin lighting, individual
lights for the pilots and passengers, and dimmable panel floodlights.
The flight instrumentation and avionics equipment lights are dimmable.

Instrument Lights

Instrument lighting for the airplane consists of dimmable incandescent
lights in the instrument bezels. The lights are controlled through the
INST lights control on the instrument panel bolster. Rotating the knob
clockwise energizes the lights and increases brightness. The
instrument light circuits operate on 28 VDC supplied through the 2-
amp INST LIGHTS circuit breaker on Main Bus 1.

Panel Flood Lights

A string of red LEDs mounted under the instrument panel glareshield
provide flood lighting for the instrument panel. The lights are controlled
through the PANEL lights control on the instrument panel bolster.
Rotating the knob clockwise energizes the lights and increases
brightness. The panel lights operate on 28 VDC supplied through the
3-amp CABIN LIGHTS circuit breaker on Main Bus 2.

Reading Lights

Individual eyeball-type reading lights are installed in the headliner
above each passenger position. Each light is aimed by positioning the
lens in the socket and is controlled by a push-button switch located
next to the light. The pilot and copilot reading lights are also dimmable
through the PANEL lights control on the instrument panel bolster. The
lights are powered by 28 VDC supplied through the 3-amp CABIN
LIGHTS circuit breaker on Main Bus 2.

Overhead Dome Light

General cabin lighting is provided by a dome light located in the
headliner at the approximate center of the cabin. The dome light is
controlled through the OVERHEAD light control on the instrument
panel bolster. Rotating the knob clockwise from the off position will
illuminate the light and control its intensity. The lights are powered by
28 VDC supplied through the 3-amp CABIN LIGHTS circuit breaker on
Main Bus 2.
