There's no such thing, in aviation, as TOO much caution... hence the reason the industry has expended so much time, energy and talent in creating backup systems for critical functions in today's aircraft. One of the true leaders in the aero-backup technology arena is Mid-Continent Instruments and Avionics.
Their latest offering is an impressive effort to create an even more redundant cockpit... and to do so with a bit of technology that not only provides critical standby info, but does so elegantly and easily. The MD302 Standby Attitude Module (SAM) is an entirely self-contained, solid-state instrument that provides attitude, altitude, airspeed and slip information to the pilot during normal operation or in the case of primary instrument failure.
SAM is a compact device specifically designed to fit in less panel space than a standard set of 2-inch mechanical attitude, altitude and airspeed indicators. Its unique, two-screen display features selectable horizontal and vertical orientation. This allows for flexible cockpit installation without extensive rearrangement of equipment or the need for re-certification of relocated avionics. Weighing 1.6 pounds, SAM is lighter than just one of the three instruments it is designed to replace.
