INTRODUCTORY PRICE THROUGH AUGUST 2026:  $69.95

 

SafeAlt puts the information that matters most in flight where it belongs: front and center.

 

The 2026 SafeAlt update is not a cosmetic refresh. The instrument has been rebuilt around a clearer, more useful altitude presentation.

 

The Portable SafeAlt brings everything about altitude into one clear instrument. It gives a useful picture of where you are, whether you are climbing or descending, how quickly altitude is changing, what the temperature is, and what that temperature means for aircraft performance.

 

The new 2026 display gives the altimeter a larger visual presence, adds a dedicated analog VSI alongside the digital vertical-speed readout, and keeps altitude, temperature, density altitude, Kollsman setting, and battery voltage visible together.

 

Density altitude has also been improved. SafeAlt now uses the pressure sensor’s own factory-calibrated temperature measurement, and the temperature driving the calculation is displayed directly on screen.

 

A new Altitude Adjust setting allows SafeAlt to be fine-tuned against a trusted reference. The correction is stored in memory and also feeds the density-altitude calculation.

 

Other 2026 improvements include:

  • Larger analog altimeter presentation
  • Analog and digital VSI
  • Dedicated temperature display
  • Improved density-altitude calculation
  • Stored altitude adjustment
  • Temperature trim
  • Battery-voltage display
  • Automatic low-battery dimming
  • Full U.S. and Rest-of-World units
  • Faster, smoother altitude and VSI response
  • Simplified controls, with the previous altitude alarm and buzzer removed

 

The result is a more focused instrument: easier to read, easier to understand, and much more useful in the cockpit.

 

SafeAlt is available in two versions:

Orange Case

Black Case

 

The electronics, software, display, and performance are identical. Choose the color that fits your cockpit.

 

Add the optional Panel Mount Holster to fit SafeAlt into a standard 3⅛-inch instrument cutout or mount it to a flat surface.

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.
