2.2.4 GMA 1360D Audio Panel

The GMA 1360D is a vertically oriented panel-mounted audio controller and marker
beacon system that collects, processes, and distributes audio signals between avionics,
crew, and passengers. LED illuminated push buttons allow for the selection of active
radios, as well as entertainment audio. LED brightness is adjusted to a level appropriate
for ambient cockpit light conditions automatically by the GDU. The GMA 1360D is a high
fidelity digital audio panel with improved circuitry that makes audio signals less prone to
noise (e.g. whining sound of an alternator or blip sound from a radar). At the core of the
GMA 1360D is a digital signal processor (DSP) that cleans up audio using advanced
filtering techniques and provides VOX control for mic inputs. The GMA 1360D outputs
feature high quality digital-to-analog converters and headset amplifier circuits that are
used to minimize noise and distortion. The GMA 1360D provides a speaker output that
may be used as a cockpit speaker or for a PA system to address passengers.
The GMA 1360D digitally records audio and plays the recordings back. The GMA 1360D
provides an intercom communication system (ICS) which controls communication paths
between pilot, copilot, and passengers. The ICS also allows independent volume
adjustments for the pilot, copilot, and passengers. Additionally, there is a volume
adjustment for the MKR, AUX, MUSIC, and TEL sources.
A failsafe circuit connects the pilot headset and microphone directly to the on-side COM
when power is removed from the unit. This circuit will also connect Pilot PTT to the on-
side MIC KEY and pilot headset to a failsafe warning audio input. The GMA 1360D is
available as a dual audio panel installation. A GMA 1360D installation can provide
redundancy and additional support for COMs, radios, or headset positions, as required
by an installation. The GMA 1360D includes Bluetooth® technology, used to wirelessly
connect smartphones and tablets to stream audio and make phone calls. The GMA
1360D also connects wirelessly to a VIRB XE, eliminating the need to install a headset
audio cable.

2.2.5 GMC 710 AFCS Controller

The GMC 710 Autopilot Mode Controller provides pitch and roll commands and displays
them on the PFDs. The mode logic and flight director calculations are performed by the
Garmin GIA 64W Integrated Avionics Unit (IAU) and are displayed on the pilot's and
copilot's GDU 1050 primary flight displays.
The AFCS function of the IAU supplies flight director steering commands and
annunciations in relation to the active pitch and roll flight director modes. The AFCS
system continuously monitors the flight director and autopilot functions for correct sensor
data. If the flight director modes cannot be calculated, the flight director and autopilot will
automatically disengage. If sensor data for the autopilot or yaw damper are not correct,
these modes automatically disengage.
