Albuquerque, NM - March 12, 2014: Sandia Aerospace announced today the introduction of the SAI 340 Quattro, a cost-effective replacement for steam-gauge standby instruments in EFIS-equipped aircraft. The Quattro displays indicated airspeed, barometric altitude, roll and pitch and provides a slip indication.

“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.”

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.
