Sandia Aerospace Receives TSO Approval for the SAI340 Quattro

Sandia Aerospace received TSO approval from the Federal Aviation Administration for the SAI 340 Quattro. The SAI 340 is a four-in-one unit that provides attitude, altitude, airspeed and slip in an electronic format. "We have delivered a tremendous number of features in the Quattro, especially considering it weighs just half a pound," said Dennis Schmidt, Sandia president. "It's an excellent safety-enhancing addition to a panel's traditional six-pack." According to the company, the Quattro can replace existing vacuum attitude instruments as a minor installation.
For backup, the Quattro has a small, rechargeable lithium battery that can operate for two hours of nominal time and 30 minutes minimal time.
