SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The model MD302 series SAM® Standby Attitude Module is a self-contained situational awareness
instrument that provides aircraft attitude, altitude, airspeed, and slip indication, plus available
heading data with the optionally installed MD32 Magnetometer. The remote version of the MD302,
part number 6420302-3, is specifically designed as a compact and innovative solution for maximum
flexibility, providing the needed positional awareness for navigation, autopilot function, or related
applications. Its size and remote capability allow it to be installed almost anywhere convenient and
provides critical information to the equipment that needs it.
The MD302 provides critical flight and situational data to the pilot and crew under any
circumstances you are likely to encounter. The design is built around a solid-state electronic sensor
array for high reliability and accuracy.
Regardless of the aircraft you are flying, the MD302 is a great fit. With a 10 to 32 volt DC input
range, the unit will work with 14 or 28V aircraft electrical buses. The operation and certification of
the MD302 make it well suited for Part 23 and 25 fixed-wing applications as well as Part 27 and 29
rotorcraft.
