Equipment
Description
Power Source
AC power supply of 115 V, 400 Hz as defined by Radio Technical Commission
for Aeronautics, Inc. (RTCA) D0-160C. The -1101 and 1212 are rated for
DO-160E variable frequency operation with harmonic content correction.
NAV Control Panel
DME frequency automatically paired with NAV frequency. Must provide remote
control of frequency selection in serial digital ARINC 429 format, power on-off,
and self-test in ARINC 429 format.
Distance Indicator
A display which indicates distance to the selected DME ground station.
Communication with DMA-37B is on an ARINC 429 data bus.
Audio Distribution System
Audio system with an input impedance of 200 to 10,000 ohms.
DME Antenna
L-Band, vertically polarized antenna capable of receiving DME signals over a
frequency range of 962.00 MHz to 1213.00 MHz, and capable of transmitting
DME signals over a frequency range of 1025 MHz to 1150 MHz.
4 MCU Unit Mount
Interrogator in the aircraft. Designed in accordance with ARINC 600. Mount
connector will allow mating of DMA-37B low-insertion force, size 2, ARINC 600
connector with three inserts. The middle insert will be used for aircraft
interconnections. The bottom insert will be used for input power. The middle
insert is also used for coaxial antenna connections. Keying pins will be indexed
to pin code 03.
Cooling Source
Aircraft supplied ARINC 600 forced-air cooling is required for the DMA-37B.
Cable and Connectors
Necessary connectors, power cables, RF cables, and aircraft interwiring are
shown in DMA-37B DME System Interwiring Diagram,
