The SAI 340 Quattro is Four-In-One standby instrument that gives you precision Airspeed, Attitude, Altitude and Slip indications, all in an easy to read EFIS presentation. The Quattro can serve as a cost effective replacement for steam-gauge standby instruments in retrofit EFIS equipped aircraft, providing for a more consistent user interface during emergency operations. It can also be an excellent safety enhancing addition to your traditional six pack panel. Additionally, the Quattro Plus has a built-in battery which provides up to two hours of stand-alone operation if needed—thus ensuring an added level of redundancy. The MFD fits directly into a standard round 3” instrument hole with no panel modification, making it a near drop-in installation.
