G1000-style audio panel

The G1000's audio panel, its later version: a tall strip that sits between the PFD and the MFD. Its keys pick the COM you transmit on, which COMs and NAV aids you hear, the marker and the speaker, each with a triangular annunciator above it that lights green. The red DISPLAY BACKUP button puts both G1000 displays into reversionary mode.

Features

Two columns of keys laid out as on the real unit: COM1 MIC / COM1, COM2 MIC / COM2, COM3 MIC / COM3, COM 1/2 / TEL (the COM keys boxed together), PA / SPKR, MKR MUTE / HI SENS, DME / NAV1, ADF / NAV2, AUX (with the photocell beside it), MAN SQ / PLAY, PILOT / COPLT (in the CREW / ICS ISOLATION box)
Each key has a triangular annunciator above it that lights green, following the sim: the MIC you transmit on, the COMs you hear, and the NAV1, NAV2, DME, ADF, MKR and SPKR audio
COM3, COM 1/2, TEL and AUX are dark, as in the Nav III installation
PA, HI SENS, MAN SQ, PLAY, PILOT and COPLT toggle their own lights. They have no sim counterpart
PILOT – PASS intercom dual knob with VOL and SQ lights. Pushing it switches between volume and squelch
DISPLAY BACKUP: the round red button turns reversionary mode on by hand and glows while on. The PFD and MFD each show the flight display with the engine strip. Press it again to go back
Key legends and printing backlit at night

On the iPad

Tap a key to toggle it. COM1 MIC / COM2 MIC selects the transmitting COM. COM1 / COM2 turns listening to that COM on or off
Tap NAV1, NAV2, DME, ADF, MKR MUTE or SPKR to toggle that audio in the sim
Push the PILOT knob to switch between VOL and SQ. Turning it has no effect
Tap DISPLAY BACKUP to turn reversionary mode on or off

Settings

Simulator data

What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.
