OPERATION
Emergency Descent Mode
The AFCS has an emergency descent mode
(EDM) that enables the AP, when pressurization
is lost, to automatically descend the aircraft
to 15,000 feet at VMO/MMO, regardless
of pilot physiological condition (Figure 16-44).
The aircraft must be above 30,000 MSL for
EDM to arm. To exit EDM, disconnect the AP.
If the AP is engaged, and the onboard cabin
pressure sensors detect a cabin altitude greater
than 14,500 feet, the AP automatically enters
EDM, and displays EDM (white letters in a red
box) on the PFDs.
During EDM, the AFCS:
• Selects HDG mode and sets heading
(heading bug on the PFD HSI) to 90° left
of the current heading
• Selects FLC mode, 0.63 m and sets altitude
preselect (altitude bug on the PFD
altitude display) to 15,000 feet
To enable the maximum possible descent rate
when in EDM, the pilot should immediately:
• Reduce throttles to IDLE
• Extend speedbrakes
AUDIO PANEL
DESCRIPTION
The Mustang avionics system includes an audio
panel for each crewmember (pilot and copilot).
The audio panels are visible as vertical switch
panels on the instrument panel immediately
outboard of each PFD. Each audio panel includes
an audio amplifier, a marker beacon receiver,
and controls for selecting and managing
audio sources. These panels manage all audio
sources, including COM transceivers, NAV,
ADF, DME and marker beacon receivers, aircraft
intercom and aural warning systems. They
also control the switching of microphones and
headsets. The audio panel also includes a digital
voice recorder, which holds up to 2 minutes

and 30 seconds of recorded audio to assist the
pilot in recording ATC clearances.
CONTROLS AND INDICATIONS
The audio panels use small keys for each item.
Above each key is a small, triangle-shaped
LED indicator, which illuminates when the
device for the corresponding button is selected
on that audio panel (Figure 16-45 and Table
16-9). Each audio panel may have different selections
from the other panel.
Power-Up
During aircraft power-up, all audio panel annunciators
illuminate for 2 seconds. Then all
the audio switch selections (and annunciators)
return the setting in effect when the aircraft
was powered down. There are two
exceptions: The speaker and intercom are always
activated during power-up, and remain
active until deselected.
Fail-Safe COM Operation
If both GIAs fail, the audio panels directly connect
