have seatback pockets. Each is equipped with an
adjustable headrest and an inboard stowable armrest.
Three-point restraint harnesses are installed.
Dual tinted sun visors are installed above the windshield.
A magnetic compass and an assist handle are installed
on the windshield center post. Air vents and foot warmers
are placed on each side with control of the cockpit
temperature separate from the cabin. Dual cupholders
are installed on both pilots' sideledges below which are
map pockets. Flight manual and chart case storage is
located in the right hand forward storage cabinet within
reach of the pilot.
The brightness of the display units may be set to selfadjust
through feedback from a photocell or may be
manually controlled through a knob on the lighting panel.
A soft key menu on the PFDs also provides manual dimming
control. All other panel lights are LEDs and manually
controlled by a knob on the lighting panel. Individual
map lights and a panel focused floodlight, each with
adjacent controls, are provided overhead in the cockpit.
Two overhead speakers are part of the audio system
as well as headset outlets in the sideledges. Two pairs
of Telex Airman 850 Active Noise Reduction headsets
are included. The emergency oxygen system provides
two quick-donning diluter demand masks for the crew
members, stowed in a container on the divider behind
each pilot seat. The pedestal is shaped to allow easy
ingress and egress. The cockpit may be closed from
the cabin with a curtain.
10.4 Avionics
Described below is the Citation Mustang standard avionics
suite as referred to in section 17, Limited Warranties.
The Garmin G1000 is an integrated avionics and flight
guidance system providing flight, navigation, communication,
surveillance, situational awareness, and aircraft
systems status and alerting on three large glass displays.
The system incorporates numerous functions and
features; only a few may be described in this document.
A. Electronic Flight Instrument System (EFIS)
The G1000 system utilizes two 10.4 inch (26 cm) (diagonal)
Control Display Units (GDU 1040A) as Primary Flight
Displays (PFDs) and one 15 inch (38 cm) (diagonal)
Control Display Unit (GDU 1500) as a Multi-Function
Display (MFD). All three are XGA Thin Film Transistor
Liquid Crystal Displays (TFT LCDs) having a resolution of
1024 x 768.
Behind each PFD and within the pressure vessel are the
main Garmin Interface Adapter Units (GIA 63W) incorporating
all communication, navigation, automatic flight
control, and extensive data management functions.
These two interface adapter units are directly linked to
the AHRS, ADCs, transponders, audio panels, and
Engine/Airframe Interface units (GEA 71, located in the
tailcone). Data from each source is processed and sent
to the Control Display Units for display on the PFDs and
MFD. Ethernet architecture and various ARINC cabling
are used for high-speed data transfer. Most components
are line replaceable units (LRUs) contained in two integrated
avionics racks.
Three glareshield cooling fans continuously circulate
cockpit air around the avionics whenever cockpit temperature
is above 40° F and the battery is on, or when
the airplane is airborne. In addition, when the cockpit
evaporator fan is in use by the pilot, a dedicated vent
diverts some chilled air around the avionics.
B. Primary Flight Display (PFD)
The following elements are shown on the PFDs in normal
mode: attitude (full screen horizon line), altitude tape
(feet or meters with six-second trend vectors), airspeed
tape (with six-second trend vectors), Mach, vertical

speed, flap limit speeds, slip/skid, heading, horizontal
situation, glide slope, flight director (cross pointer or single
cue), navigation and communication frequencies
(active and standby), navigation station/waypoint identification,
track, distance, transponder code, altimeter setting
(inches or hectopascals), clock, timer (up or down),
temperature (RAT), ISA deviation, and many other
items. V-speeds are entered manually by the pilot and
will appear on the airspeed tape. At the bottom edge of
the display several menu items are shown directly above
corresponding soft keys on the bezel. The soft keys are
used to select the menu and submenu items. Selection
of the "Inset" soft key places a smaller version of the
MFD navigation map in the lower left corner of the PFD
for added situational awareness.
C. Multi-Function Display (MFD)
