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 200kts.  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?

AV-30-C is not approved for primary IFR GPS navigation.  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 to an external GPS navigator or hand-held, AV-30 operates as a repeater display. The data provided includes current waypoint ID, [...]

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 [...]

Does the AV-30 support a magnetometer?

By default, the AV-30 is a non-slaved DG. The good news it that this reduces installation complexity dramatically (no GPS antennas required, no remote mount magnetometers, no field mapping, no calibration). Power and ground are the only required connections when the unit is installed as a DG. The bad news is that it operates the [...]
