SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The model MD32 Remote Magnetometer, part number series 6420032-( ), extends the
functionality of the MD302 Standby Attitude Module to a full air data, attitude and heading
reference system (ADAHRS) solution. By providing magnetic heading data, the MD32 enables
the MD302 to independently meet the gyro-stabilized heading indication requirements of TSO-
C6e as part of the integrated cockpit display, or as a remote data source.
The MD32 provides ARINC 429 data by way of a simple 4-wire shielded cable connecting data
and power to the MD302. As an added benefit, the backup battery integral to the MD302 is also
capable of supporting the MD32 Remote Magnetometer in the case of aircraft power loss
(MD302 Mod 2 versions or greater).
The MD32 option for the MD302 is suitable for certified aircraft in 14 CFR, Part 23, 25, 27, or
29. The MD32 series Remote Magnetometer is FAA certified to TSO-C6e, with embedded
software designed to RTCA/DO-178C, Design Assurance Level A (DAL A), and tested to the
rigorous environmental standards of RTCA/DO-160G.
Highlighted features include: all solid-state components, easy and flexible installation, on-aircraft
calibration, and a small, light-weight housing appropriate for installations in a wing or tail
location.
