Airspeed + TAS + Altitude + VSI + OAT + G-Meter

RADIANT'S Universal Airspeed Indicator (RUASI) is built for pilots who want airspeed to remain the primary visual focus. Its main dial presents indicated airspeed in a clear analog-style format, while the instrument’s right-side data stack adds digital altitude, true airspeed, outside air temperature, and vertical speed in a compact, easy-to-scan layout. When enabled, the new G-meter becomes part of the dial rotation as well.
 
Rather than acting like a single-purpose ASI, UASI gives the builder a more capable instrument without losing the familiarity of a dedicated airspeed presentation. It is especially attractive when airspeed warrants the greatest visual emphasis, but extra information still needs to earn its place in the panel.
 
The updated platform allows meaningful aircraft-specific setup.
 
UASI supports 100 or 200 top-of-scale airspeed range selection, knots or MPH, inHg or hPa Kollsman units, °F or °C temperature display, and user-settable airspeed arc values including VSO, VS1, VFE, VF1, VNO, and VNE. The airspeed sensor may also be zeroed and saved to non-volatile memory.
 
An external temperature probe is included, and UASI is available in both 2-1/4 inch and 3-1/8 inch versions for flexible installation.

REGISTER YOUR PRODUCT HERE and be notified when there are firmware updates.

We are in the business of offering innovative aircraft instruments for experimental aircraft flying, and backup / CO instruments for general aviation (non-TSO/non-PMA). 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.

Support

If you need support for your Radiant instrument purchase, please contact us by email at support@radiantinstruments.com. Because of our small staff, we do not have a direct phone number.  We do our best to respond to emails as soon as possible. If you do not hear from us within 48 hours, please try again. You may also try kathy@radiantinstruments.com. Please check our our Warranty Information here.

Shipping Information

Since we offer innovative aircraft instruments, we often introduce new products for sale that are in the final engineering phase. Sometimes an engineering problem emerges in the final phase that delays our production runs. This means that if you are ordering a new product, we could be several weeks out from shipping. We try to keep our product pages up to date with shipping information.

​

As of 2025, there are only two of us working Radiant instruments. We manufacture products in batches, and cycles take about a month. It is always best to order now and get on the list. We do charge your card at the time your order is placed.

 

We are ship by USPS Ground Advantage. We do not ship internationally, but our distributor, Aircraft Spruce does. Please order at https://www.aircraftspruce.com/. Search "RADIANT" and most of our products should pop up.

Radiantly brilliant- truly affordable, made with pilots specifically in mind, and solving a problem that isn’t optional, but can easily cost 10x+ to mitigate. Thank you for everything you’ve done to make safer flying more accessible and affordable.
