Gives Nearly Immediate Vertical Speed Information

The FAA has granted SANDIA Aerospace an additional TSO on their popular SAI 340 Quattro multi-function indicator. In addition to Attitude, Altitude, Airspeed and slip, the SAI 340 is now TSO’d for (I)VSI. (I)VSI is Instantaneous Vertical Speed.

Unlike a standard VSI that has a 6-8 second lag, the SAI 340 gives virtually immediate vertical speed indications. The vertical speed is shown on the SAI 340 in both a tape and digital format. In addition to the (I)VSI, the new software version also adds an adjustable Altitude Bug.

The SAI 340 is a stand-alone Attitude indicator that is ideally suited for stand-by applications with today’s glass cockpits. It is also suitable as a stem gauge replacement unit in older aircraft. The SAI 340 has an internal battery that provides two hours of stand-by operation in case of loss of aircraft power. The lithium-ion battery is enclosed in a metal case and meets the requirements of RTCA DO-347, ensuring safe operation. With the addition of the (I)VSI TSO, the SAI 340 now holds 8 separate TSO’s.

Existing SAI 340 can arrange to get their units upgraded to the latest software by contacting the SANDIA Aerospace service department at service@sandia.aero or by phone at 505.341.2930.
