The uAvionix AV-20E is a multifunction electronic flight instrument developed for experimental and light sport aircraft. Designed to install in a standard 2-1/4 inch round instrument cutout, the AV-20E replaces multiple legacy analog gauges with a single, compact digital display while offering extensive configurability and modern flight data presentation.
Primary Flight Instrument Functionality
The AV-20E provides solid-state attitude information using internal sensors, delivering reliable pitch and roll indications without the mechanical limitations of traditional gyroscopic instruments. In addition to attitude, the instrument can display airspeed, altitude, vertical speed, heading, slip/skid indication, g-load, and other configurable flight parameters.
Multiple screen layouts and display modes allow pilots to tailor the presentation for their aircraft and mission profile, making the AV-20E suitable for VFR, cross-country, and performance-focused flying.
Angle of Attack and Energy Awareness
The AV-20E includes integrated angle of attack (AoA) capability when connected to appropriate pitot and static pressure sources. Visual AoA cues help pilots manage energy state, approach consistency, and stall margins, providing valuable feedback during critical phases of flight.
This functionality is especially beneficial in experimental aircraft, where aerodynamic characteristics and loading can vary significantly between designs.
Heading, GPS, and Magnetometer Integration
When paired with an external magnetometer, such as the uAvionix AV-Mag, the AV-20E provides stabilized magnetic heading, allowing it to function as a digital heading reference. The instrument also supports serial connectivity to compatible GPS sources, enabling display of ground track and additional navigation data.
The experimental approval basis allows broader integration flexibility compared to certified systems, making the AV-20E adaptable to a wide range of avionics configurations.
Internal Backup Power and Reliability
An internal rechargeable backup battery allows the AV-20E to continue operating in the event of aircraft electrical system failure. This enhances safety by maintaining critical flight information even during partial or complete loss of aircraft power.
Solid-state sensors eliminate vacuum system dependencies and mechanical wear, reducing maintenance requirements and improving long-term reliability.
Installation Flexibility for Experimental Aircraft
The AV-20E is designed as a drop-in replacement for traditional round instruments, minimizing panel modification and installation complexity. Builders and owners benefit from flexible configuration options, customizable display layouts, and firmware-based feature enhancements.
Software updates allow the AV-20E platform to evolve over time, adding functionality and refinements as supported by the experimental installation environment.
