LIGHTING SYSTEMS
COCKPIT
An overhead light control panel, accessible to both pilots, incorporates a functional arrangement of all
lighting systems. Each light group has its own rheostat switch placarded BRT – OFF. The MASTER
PANEL LIGHTS – ON – OFF switch is the master switch for: PILOT PFD, STANDBY INSTRUMENT
LIGHTS, MFD, OVERHEAD PED & SUBPANEL LIGHTS, SIDE PANEL, CLOCKS, and COPILOT PFD.
PILOT PFD – Controls the brightness of the pilot’s PFD.
STANDBY INSTRUMENT LIGHTS - Controls the brightness of the internal lighting for the
standby attitude indicator, standby altimeter, and standby airspeed indicator.
MFD – Controls the brightness of the Multi-Function Display (MFD).
OVERHEAD PED & SUBPANEL LIGHTS - Controls the brightness of the backlighting of the
overhead light control panel and internal lighting of the overhead electrical gauges, throttle
quadrant backlighting, internal lighting for pedestal-mounted gauges, and the MFD Controller
panel backlighting, and the subpanel backlighting.
SIDE PANEL - Controls the brightness of the backlighting of the right side circuit breaker panel,
the left side circuit breaker panel and the fuel gauge panel.
CLOCKS – Controls the brightness of the clocks mounted in the pilot’s and copilot’s control
wheels.
COPILOT PFD – Controls the brightness of the copilot’s PFD.
Separate rheostat switches individually control the instrument indirect lights in the glareshield and
overhead map lights.
PITOT AND STATIC SYSTEM
PITOT
The pitot heads are the sources of impact air for the operation of the flight instruments.
A heated pitot mast is located on each side of the lower portion of the nose. Tubing from the left pitot
mast is connected to the pilot’s Air Data Computer (ADC1), and tubing from the right pitot mast is
connected to the copilot’s Air Data Computer (ADC2) and the standby airspeed indicator. The switch for
the PITOT – LEFT – RIGHT – OFF is located in the ICE PROTECTION group on the pilot’s right
subpanel.
