GENERAL DESCRIPTION

INTRODUCTION
The model MD302 series Standby Attitude Module is a self-contained situational awareness instrument
that provides aircraft attitude, altitude, airspeed and slip indication. The compact and innovative design
of the MD302 is specifically developed for maximum flexibility for installation in retrofit or modern
instrument panel. Its size, extra-wide viewing angle and AnyWay selectable orientation allows it to be
installed almost anywhere in the instrument panel and in less space than traditional 2-inch mechanical
standby or primary flight instruments.
Regardless of the aircraft you’re 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 and the selectable lighting input allows operation
with 5, 14 or 28V lighting systems. 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.
The MD302 provides critical flight and situational data to the pilot and crew under any circumstances
you’re likely to encounter. The design is built around a solid-state electronic sensor array for high
reliability and contains an integral and rechargeable Nanophosphate
®
lithium-ion battery that can power
the unit for up to two hours if main aircraft power is lost. The dual, high-resolution LCD display uses
smooth graphics, daylight-readable brightness, and a configurable lighting response curve to ensure
optimal visibility in all conditions.
The user interface of the product allows for simple, intuitive operation using a single push-and-turn knob
that easily navigates through the user options and menu screens. The interactivity of the unit means that
it can receive and transmit ARINC 429 data communications. Functional outputs of attitude, altitude, and
airspeed can be used for monitoring or backup information while baro input data can be received that will
synchronize the baro setting with the primary system to eliminate redundant task loading for the pilot.
The MD302 is an excellent complement to your avionics suite as a reliable and state-of-the-art instrument
that is an essential part of any instrument panel.
