The Mustang's large MFD serves primarily as a moving
map and EICAS platform. The moving map may be populated
with a wide variety of information including traffic,
terrain, airborne weather radar, data link weather, political
and airspace boundaries, airports, navaids, waypoints,
cities, roads, Garmin FlightCharts and Safe Taxi,
and many others, all at various ranges. The pilot may
choose a north-up or track-up orientation. These and
many other options may be selected using the soft keys
along the bottom edge of the bezel or by using the
remote FMS / MFD control keyboard located on the
pedestal. A subscription through Garmin is required for
database updates.
D. Engine Indicating and Crew Alerting System
(EICAS)
The EICAS information is presented on the left side of the
MFD and includes: engine speeds and temperatures; oil
pressures and temperatures; fuel flow, quantity and temperature;
electrical and pressurization systems data; and
trim and flap positions. The crew alerting section shows
colored text messages as determined by system inputs.
Up to 13 messages are shown in the CAS box; additional
messages may be scrolled into view by using the MFD
soft keys. Pre-programmed logic determines the color,
order, and flashing characteristics of all messages.
Each display may show the essential components of the
EICAS in reversionary mode. Reversion may be selected
manually or will occur automatically if necessary.
E. Air Data and Attitude Information
The pitot-static system includes two electrically heated
pitot and static sources. Each is cross-plumbed into dual
solid state digital air data computers (ADCs) located
behind each PFD. The ADCs perform source error corrections
and calculate indicated airspeed, true airspeed,
mach number, vertical speed, density altitude, pressure
altitude, and total temperature for output to the Interface
Adapters and the PFDs.
In addition, ADC output is received by the integrated
Attitude and Heading Reference Systems (AHRS). Two
solid state digital AHRS reside behind the MFD and are
each tied to the three-axis magnetometers located in the
tail. The AHRS are capable of in-flight and on-the-move
initialization. Output from the AHRS is received and
processed by the Interface Adapter Units and the PFDs.
The system meets RVSM requirements.
Input from an electrically heated stall warning vane on
the right side of the nose is processed by the Interface
Adapter Units for display on the PFDs and for input to
the aural warning system. Dual outside air temperature
probes (GTP 59) are provided to feed temperature data
to the ADCs.
F. VHF Communication Transceivers
Dual VHF communication transceivers are part of the
Interface Adapter Units and provide 16 watts of transmission
power. They are compliant with European 8.33
kHz channel spacing requirements. Tuning and management
is accomplished through dual concentric knobs
on each PFD bezel. An HF radio is available as an
option for units 33 and on.
G. Audio Control Panel
Dual Garmin GMA 1347D digital audio control panels
provide transmitter selection for microphone inputs and
direct audio outputs from all receivers to the speakers
and/or headphones at each crew station. The system
includes crew intercom and the ability to record and playback
up to 2½ minutes of incoming audio. One handheld
microphone is connected to the pilot's audio panel.
H. Navigation
Dual Garmin navigation receivers located in the
Interface Adapter Units provide VOR, Localizer and
Glideslope functions. The Marker Beacon receivers are

integrated in the Audio Panels. Navigation information is
displayed on both PFDs and the reversionary mode of
the MFD. Tuning and management is accomplished
through dual concentric knobs on each PFD bezel. A single
ADF receiver may be ordered as an option.
I. Distance Measuring Equipment (DME)
A single DME is located in the nose of the aircraft forward
of the baggage compartment. DME information is
tuned via the navigation receivers and can be displayed
on each PFD.
J. Global Positioning System (GPS)
Each Interface Adapter Unit includes a WAAS capable
GPS receiver. Both receivers are capable of monitoring
12 channels to provide satellite-based position data for
use by the FMS.
K. Flight Management System (FMS)
The Garmin FMS provides a multiple waypoint navigation
solution suitable for enroute, terminal, and WAAS
precision approach navigation. An alphanumeric keyboard
