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.
Per the manufacturer: Yes, it does have auto dimming based on ambient lighting conditions. The pilot can also override the auto dimming at any time and set his own level of desired lighting.
The SAI Quattro is TSO’d as a primary attitude indicator.
The SAI Quattro is covered under a 3 year warranty. As this is a new unit, no mean time between failure data has been collected.
The SAI Quattro has received FAA TSO approval on 10/15/15.
No, for primary use the SAI 340 will only replace your artificial horizon.
Yes, it is approved as a primary or standby attitude indicator.
No, the lubber line can not be adjusted to match the horizon.
This unit is TSO approved and does not require a field approval.
Per Sandia: No, this unit will not integrate with a KAP150 autopilot unit.
No, this is not NVIS compatible.
