ABOVE: The AV-30-E is the tenth backup EFIS device approved by the LAA for use in Permit aircraft

The Light Aircraft Association has added the uAvionix AV-30-E to the list of approved backup EFIS (Electronic Flight Instrument System) instruments permitted for use in Permit aircraft.

“The EFIS units listed in TL3.20 may be used without further reference to LAA Engineering, although your LAA inspector will need to make a Permit Maintenance Release (PMR) entry in the airframe logbook quoting this Technical Leaflet reference,” notes the LAA in a statement.

The uAvionix AV-30-E device includes an ASI, altimeter and compass as standard, with an optional magnetometer. “Upgrade your legacy vacuum-driven instruments to digital precision attitude and directional gyro customizable displays,” says the manufacturers’ website, which also details the “14-in-one functionality” of the device.

The AV-30-E fits in an existing three inch panel slot, eliminating the need for cutting or substituting the panel, and can be mounted from behind to ‘preserve the ’round dial’ look’. Inkeeping with the LAA stipulation that backup EFIS instruments must “incorporate their own backup power supply capable of sustaining the instruments for at least 30 minutes (either internally or externally),” the AV-30-E features up to two hours typical battery operation at 20 degrees C, and 30 minutes minimum at minus 20 degrees C.
