To Our Customers
Radiant Instruments is a small aviation company that develops innovative avionics for experimental aircraft, carbon monoxide detectors for the cockpit, and portable aviation instruments (non-TSO/non-PMA). Products are engineered and designed by our founder, with final assembly, calibration, and quality control at our facility in Wichita, Kansas.
The instruments from Radiant Technology are not designed to be used in applications where their failure would endanger safe flight or human life in any way. They are intended solely for use in VFR conditions. They are not certified to meet any Technical Standard Order, and are not produced under a Parts Manufacturing Authority (TSO / PMA). As a result, they are suitable only for use in experimental and ultralight aircraft, and in Light Sport Aircraft, if meeting the requirements of the respective manufacturer.
