DA 62 AFM Airplane Description
7.13.4 AUDIO PANEL
The audio panel contains traditional transmitter and receiver selectors, as well as an
integral intercom and marker beacon system. The marker beacon lights appear on the
PFD. In addition, a clearance recorder records the last 2 ½ minutes of received audio.
Lights above the selections indicate what selections are active. Pressing the red DISPLAY
BACKUP button on the audio panel causes both the PFD and MFD to display a composite
mode.
7.13.5 ATTITUDE AND HEADING REFERENCE SYSTEM (AHRS)
The attitude and heading reference system (AHRS) uses GPS, rate sensors, air data,
and magnetic variation to determine pitch and roll attitude, sideslip and heading. Operation
is possible in a degraded mode if the system loses any of these inputs. Status messages
alert the crew of the loss of any of these inputs. The AHRS will align while the airplane
is in motion, but will align quicker if the wings are kept level during the alignment process.
7.13.6 AIR DATA COMPUTER (ADC)
The air data computer (ADC) provides airspeed, altitude, vertical speed, and air
temperature to the display system. In addition to the primary displays, this information
is used by the FMS and TIS systems.
7.13.7 GWX 70 WEATHER RADAR
The Garmin GWX 70 Weather Radar System provides information about precipitation
conditions ahead of the airplane. The system consists of a combined microwave
transmitter and receiver system in the nose cone, mounted to the front baggage
compartment bulkhead. The system is connected to the electrical system of the airplane
via a circuit breaker on the instrument panel. The processed data of the GWX 70 system
is displayed on the Garmin G1000 MFD. Refer to the Garmin G1000 Pilot’s Guide, P/N
