The SAI 340 - Quattro Plus is a Five-In-One Attitude - Airspeed - Altitude - Slip indicator that now includes Instantaneous Vertical Speed (I)VSI. Unlike conventional vertical speed indicators that typically have a 6-8 second delay (I)VSI shows your vertical rate immediately, a great tool for trimming your aircraft. 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.

With its built-in battery, the SAI 340 Quattro provides up to 2 hours of stand alone operation, ensuring an unprecedented level of redundancy. Yet it weighs in at a scant 1/2 pounds, less that a typical airspeed indicator. Enclosed in a metal case, the battery meets the stringent requirements of RTCA DO-347 to ensure a completely safe operation.

The fully TSO’d display fits directly into a standard round 3” instrument hole with no instrument overlap or panel modification, making it a near drop-in installation. Stunning air-transport quality graphics provide amazingly smooth, fluid motion, making the SAI 340 an investment to be proud of - and at a price that won’t break the bank.
