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

 

SHIPS WITHIN TWO WEEKS

 

RADIANT's Universal Multi-Function Instrument (UMFI) is an all-in-one flight instrument for builders who want maximum usefulness in minimum panel space.

 

It combines both altimeter and airspeed capability in one instrument, while preserving an easy-to-read format that feels familiar in actual flight. The main dial can be switched between a conventional-style altimeter view, an airspeed view, and the new G-meter strip-chart view. At the same time, the instrument keeps a live right-side data stack visible for fast scanning.

 

In normal operation, UMFI displays indicated altitude, Kollsman setting, indicated airspeed, true airspeed, outside air temperature, vertical speed, and density altitude. Density altitude is always highlighted for quick recognition, and the built-in G-meter adds a useful picture of recent aircraft loading without requiring another instrument hole.

 

The updated platform gives the builder meaningful setup flexibility. UMFI supports 100 or 200 top-of-scale airspeed range selection, knots or MPHinHg or hPa Kollsman units, °F or °C temperature display, and customizable airspeed arcs 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 UMFI is offered in both 2-1/4 inch and 3-1/8 inch versions for flexible panel installation.

To Our Customers

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.
