controls brilliance.
COMMUNICATIONS EQUIPMENT
Introduction
The IRIS G115E / Tutor T.1 communications installation consists of Bendix/King
integrated equipment comprising a KMA 26 audio control system, a KTR 909
UHF transceiver, a KX 155A VHF NAV/COMM transceiver and a KT 73
transponder unit.
Each control column has a press-to-transmit (PTT) button and a mute switch is
located towards the left end of the Utilities panel.
The switch incorporates an amber light that illuminates on activation.
Selecting the mute switch reduces the volume of all incoming audio signals
by 6 dB thus broadcasts may still be heard but at a reduced level.
The Mute does not affect the outgoing audio signal. Deselecting mute returns
all volumes to the pre-set level.
Power is supplied to all the units via the Avionics 1 and 2 Busbars and
associated circuit breakers.
Lighting levels on the units are either automatically controlled or adjusted
using the dimmer control on the Utilities panel.
Bendix/King KMA 26 Audio Control System
The KMA 26 has a built-in 6 station intercom with 2 dedicated amplifiers. The
unit is active as soon as the Avionic Master switch is selected on.
Intercom operation may be voice activated (VOX), where the intercom
automatically becomes active when a crew member speaks or key
activated, a function not supported on this aircraft.
The unit also incorporates a Marker Receiver.
