uAvionix AV-30-C Certified 3-Inch Digital Multi-Function Display (MFD)

What is the difference between the AV-30-C and the AV-30-E?

The AV-30-C is the certified version intended for type-certificated aircraft, installed under an FAA Supplemental Type Certificate and Approved Model List. The AV-30-E is the experimental version for amateur-built and light sport aircraft. The two share the same display hardware and core functions, so the main distinction is the certification path rather than the features.

What instruments does the AV-30-C replace?

The AV-30-C is designed to replace legacy vacuum-driven instruments such as the attitude indicator and the directional gyro. It installs in a standard 3-inch round cutout and consolidates attitude, slip, direction, altitude, vertical trend, and indicated airspeed into one digital display, helping reduce reliance on the aircraft vacuum system.

Can a single AV-30-C act as both the attitude indicator and the directional gyro?

A single AV-30-C displays one primary function at a time, such as attitude or directional gyro. Operators who want both as primary instruments typically install two units, one configured for each role. Check the current installation approvals and your shop's guidance for your specific aircraft before deciding how many units you need.

Is the AV-30-C approved for IFR flight?

The AV-30-C is certified under an FAA Supplemental Type Certificate as a primary attitude indicator and directional gyro replacement. When properly installed it can support the required gyroscopic instruments for instrument flight, and pairing it with the AV-HSI module adds course guidance. Confirm the approval details for your specific aircraft with your installer.

Does the AV-30-C connect to the pitot-static system?

Yes. The AV-30-C integrates with your existing pitot-static system so it can display indicated airspeed, altitude, vertical trend, and computed values like True Airspeed and density altitude. If your aircraft is operated under IFR, the pitot-static system generally needs to be checked and recertified after the unit is added. Your installer can advise on this.

How does the probeless Angle of Attack system work?

The AV-30-C calculates Angle of Attack from the aircraft's pitch and flight path along with G-loading, so no external probe or vane is required. As the aircraft approaches a dangerous angle, the unit provides visual and aural warnings to alert the pilot before reaching an unsafe state, supporting earlier awareness of an impending stall.

What flight data and display modes does the AV-30-C offer?

The AV-30-C offers over 14 functions and customizable modes, including attitude indicator, directional gyro, multi-function display, and CDI/HSI. It can show True Airspeed, density altitude, bus voltage, G-loading on a plus or minus 8 G meter, slip, vertical trend, and a GPS navigational overlay with HSI, 360 rose, and arc map views.

What ADS-B solutions and modules work with the AV-30-C?

The AV-30-C is compatible with ADS-B solutions such as the tailBeaconX for ADS-B Out. It can also pair with the AV-HSI module for added course guidance and integration with select digital autopilots, and the AV-APA module for legacy analog autopilot integration. Accessories are sold separately, so confirm the supported list with your installer.

Does the AV-30-C have a backup battery?

Yes. The AV-30-C includes an internal battery that provides a typical 2-hour operation window if aircraft power is lost, helping it continue to display attitude and other key data during an electrical failure. Actual runtime can vary with temperature and unit condition, so treat the 2-hour figure as a typical value rather than a guarantee.

Does the AV-30-C use a GPS input?

Yes. The AV-30-C accepts GPS data from a compatible panel-mount or portable source to drive its navigational overlay, including HSI, 360 rose, and arc map views. It acts as a display for that GPS data rather than a navigator itself, so the connected GPS source determines the navigation information that is available.

What aircraft is the AV-30-C approved for?

The AV-30-C is approved under an FAA Supplemental Type Certificate with an Approved Model List that covers many common type-certificated aircraft. Because the list is specific, verify that your exact aircraft make and model appears on the current Approved Model List before purchasing. Your installer can confirm eligibility for your airplane and the applicable installation paperwork.

Can I install the AV-30-C myself?

No. As a certified instrument, the AV-30-C must be installed by a qualified avionics technician, and the installation is documented with the appropriate FAA paperwork. The unit fits a standard 3-inch round instrument hole, but wiring, pitot-static connections, and the final signoff should be handled by a licensed shop for your specific aircraft.
