Fresh back from Sandia after it was upgraded to the 340A with the latest hardware and software (version 18.2).
Certified Primary replacement replaces
(3) Turn Coordinator and
(4 Quattro) Attitude.
Now with the upgrade to the 340A it replaces (5 Cinco?) Instantaneous Vertical Speed Indicator.
Also certified as backup for EFIS or steam gauges. Built in 2 hour backup battery.
New it lists for $3595. https://sandia.aero/product/sai-340-quattro/
All paperwork included along with mounting gasket, bracket & screws. Pristine since it has a new bezel with the upgrade. For all practical purposes a brand new instrument.
If anyone has a G5 HSI certified to trade, I'd be interested in trades. I need an HSI more than I need the ADI.
