What can I use as a control head?

For certified aircraft, uAvionix offers the AV-30-C (3-inch EFIS) as a control head option. For experimental aircraft, the uAvionix AV-20-E (2-inch MFD) or AV-30-E (3-inch EFIS) may be used. Other 3rd-party EFIS units that support transponder control functionality may also be used with tailBeaconX.


Can the tailBeacon be used on rotorcraft?

For more information on rotorcraft installations please read this blog entry.  tailBeacon Approved for Rotorcraft uAvionix does not recommend installation on Bell 206B/L and OH-58 A, B and C models at this time.  If you have installed a tailBeacon on the Bell 206B, 206L, or OH-58 models please contact our support team.

What are my options if my aircraft is not listed on the AML?

The current AV-30-C AML applies to Part 23 single-engine aircraft operating under 300kts.  We have tried to include as many of the applicable aircraft as possible.  If your aircraft is not listed on the AML but does fall within the AML limitations, you may be able to obtain a field approval from your local Flight [...]


What is required for an AV-30-C installation?

The AV-30-C holds an STC-PMA with AML. The installation must be performed by a licensed aircraft technician and a 337 must be submitted as part of the installation. The AV-30-C ships with the AV-30-C, DB-15 connector, DB crimps, and a backshell for the DB connector. The DB-15 connector needs to be populated with pins based [...]


Will the initial STC have autopilot compatibility?

No, the initial STC will not have autopilot capability. Autopilot integration will be accomplished in a phased approach. The initial autopilot support will be for STEC systems (which have their own roll/pitch source) and allow the heading bug on the AV-30 to drive the heading datum input on the autopilot. This interface will be accomplished [...]


Can the AV-30 replace my mechanical AI / Direction Indicator / Turn Coordinator?

The AV-30-C is approved as a stand-alone attitude indicator, directional gyro (dual unit installation), slip-skid indicator, and as the required backup in an EFIS installation. If the installation configuration leaves no instruments that require a vacuum source, the vacuum pump system may be removed from the aircraft via a 337 field alteration process. The procedure [...]


What level of GPS integration is supported?

The AV-30 provides an RS-232 receive line for “aviation” or “moving map” output provided by virtually every panel mount GPS navigator in service. This data is broadcast by the GPS navigator and no data is sent from the AV-30 back to the GPS unit. NMEA is also supported, which is output by most hand-held GPS [...]


Is AV-30 approved for primary IFR navigation?

When connected to an AV-HSI and IFR-approved navigator, the AV-30-E can be used as a primary display of navigation guidance. This capability is not yet approved on the AV-30-C.  The AV-30-C is approved for installation as a primary Attitude Indicator or primary Directional Indicator.  The AV-30 is capable of receiving serial GPS streams.  When connected [...]


How is “Probeless”Angle of Attack Determined?

Angle of attack is determined by comparing aircraft pitch to the actual flight path angle through the air. This is equivalent to the angle at which the wing is intercepting the body of air surrounding the aircraft - exactly the same as a probe based AoA system. Pitch is determined by a precision internal AHRS, [...]


Does the Probeless AoA behave exactly like the probed system?

Yes and no. During the majority of flight conditions, they are equivalent. However, during conditions where the aircraft is moving through a mass of air that has a vertical component, the behavior is slightly different. As vertical updrafts are rarely of concern, the scenario to look at is the downdraft during final approach. In this [...]


The following aircraft have been reported to have fitment issues by customers.

What’s “In the Box”

Included are the AV-20-S with internal backup battery and two 1/4" quick connect fittings, mounting screws, a d-subminiature connector, backshell, and pins. An OAT probe is NOT included and must be purchased separately.  The AV-20-S is compatible with the industry-standard Davtron Analog probe, available through common component suppliers.  (If the OAT probe is not connected, [...]
