Four-In-One-Unit Replaces Vacuum Attitude Instruments

The FAA has sent a letter of TSO approval to Sandia Aerospace for the long awaited SAI 340 Quattro. The SAI 34 is a four in one unit that provides Attitude-Altitude-Airspeed-Slip in a easy to read electronic format.

“We have delivered a tremendous number of features in the Quattro, especially considering it weighs just half a pound,” says Sandia President Dennis Schmidt. “It’s an excellent safety-enhancing addition to a panel’s traditional six-pack.”  And with the FAA new Policy Statement PS-ACE-23-08 the Quattro can replace existing vacuum attitude instruments as a minor installation.

With solid-state reliability, the SAI 340 Quattro displays air transport-quality graphics in an easy-to-read EFIS presentation. For backup, the Quattro has a small, rechargeable lithium battery which can operate for two hours of nominal time and 30 minutes minimal time.  Other features of the Quattro include pilot-entered barometric correction, automatic and manual backlight control, internal battery charge status, and a panel-tilt configuration.

Since the Quattro was designed with 3” instrument hole mounting, installation may involving little more than dropping the unit into position.

The SAI 340 Quattro has an introductory retail price of $3595.
