Overview

Five-In-One Standby Instrument

The SAI-340 Quattro Plus is a five-in-one attitude, airspeed, altitude, slip indicator that includes Instantaneous Vertical Speed (I)VSI. With smooth, high-quality graphics and an easy to read EFIS presentation, the Quattro Plus makes a great addition to a traditional six pack panel. This instrument is a cost-effective way to replace steam-gauge standby instruments in retrofit EFIS-equipped aircraft.

    Displays precision airspeed, attitude, altitude, slip and Instantaneous Vertical Speed (I)VSI in an EFIS presentation
    MFD is an excellent replacement for steam-gauge standby instruments in retrofit EFIS equipped aircraft
    Backup lithium battery provides up to 2 hours battery life
    Fits a 3-inch panel hole

Reviews

I just installed a Sandia AI in my Twin Comanche, and I am very impressed. Would I have preferred a full up Garmin G1000? Well yes, but this product is excellent for the money. It is very bright and easy to see, even for one with less than perfect near vision. Instrument scan is now simple as attitude, airspeed and altitude are on the same instrument. Pitch representation is much more precise than with a vacuum gyro AI, as the tick marks are every 2.5 degrees of pitch rather than 5. Since I had the space, I moved my vacuum gyros over and now have the Sandia and a Sandel 3308 in the center of my instruments, but I would not be afraid to pitch all my vacuum instruments if space was a concern. They claim a greater than 10,000 hour mean time between failure. Installation was simple: power, ground, pitot, and static. The Sandia fit in the old gyro hole with no problem. Setup and calibration was simple and logical. The only thing one might like to have is a means of raising and lowering the pitch representation manually without having to go into the setup mode. If you are used to lowering the nose representation to the horizon when you slow down so it appears that you are flying in level pitch, flying with the nose up as you slow may take a little getting used to. In all, highly recommended.

My Quattro was installed in January 2016. It had to be tweaked a little to provide a straight and level indication which coincided with the actual attitude of the airplane, but once that was done, it has been perfect. It virtually eliminates any worry about a failed vacuum pump in IMC, because the only instrument dependent on the vacuum pump, the DG, is backed up with the magnetic compass. Very nice product.
