AV-20-S from uAvionix approved for IFR aircraft
February 16, 2021
The AV-20-S from uAvionix does more than time turns. It displays a trove of useful data, including attitude, angle of attack, slips and skids, G-forces, temperature, voltage, density altitude, true airspeed—and it is also a clock.
The Bigfork, Montana, firm announced February 2 that the AV-20-S (available from various sellers, suggested retail price $895) has been approved as a clock replacement for Part 23 certified, Class I and II Instrument Flight Rules (IFR) aircraft pursuant to Advisory Circular 20-94A and under FAR Part 91.205. Previous approval of the AV-20-S as Non-Required Safety Enhancing Equipment has been updated to reflect the new approval, the company noted.
Designed to fit in a standard 2.25-inch round instrument opening, the uAvionix AV-20-S collects information from a wide range of sources to serve as a standby attitude indicator (among many other functions) with 30 minutes of internal battery power available. Audio alerts can be configured for angle of attack, G-load, or roll limits.
The AV-20-S is the slightly smaller cousin of the uAvionix AV-30-S (3.125-inch) certified display that can be installed as a primary attitude indicator or directional gyro. Both are compatible with the firm’s Mode S ADS-B transponder, the tailBeaconX.
“Together the uAvionix panel display models allow for better panel utilization, the removal of high-maintenance instruments, and upgrading failure-prone vacuum-driven instruments—all while maintaining the distinguished look of a classic panel and reducing installation costs by fitting round instruments in round openings,” the firm noted in its announcement.
