ENCODER (P/N a-30) - As Removed, Serviceable

The a-30 is an altitude encoder that converts static pressure into Gray code altitude data for Mode C/S transponder systems. This FAA TSO-certified blind encoder supplies pressure altitude information to air traffic control via the aircraft's transponder. The unit mounts on an avionics tray and connects via static line pressure input and electrical wiring harness.

Installation requires routing the static line from the aircraft's static source and integrating wiring per both encoder and transponder documentation. The a-30 operates as part of the ACK series altitude encoding systems used in general aviation and commercial aircraft.

What is the ENCODER (P/N a-30)?

The a-30 is an altitude encoder that converts static pressure into Gray code altitude data for Mode C/S transponder systems. This FAA TSO-certified blind encoder supplies pressure altitude information to air traffic control via the aircraft's transponder.

Is the a-30 compatible with my aircraft's avionics suite?

Avionics compatibility depends on your aircraft model and existing installation. The ENCODER is available in: As Removed, Serviceable. We recommend checking your aircraft's wiring diagrams and STC documentation, or contact our avionics team for compatibility assistance.

Does the a-30 come with an 8130-3 airworthiness tag?

Availability of an FAA 8130-3 tag depends on the part condition. Overhauled and repaired units typically include 8130-3 documentation. As-removed units may include a removal tag with trace history. Contact us for specific documentation on the condition you need.

Do you offer bench testing for the a-30?

We can arrange bench testing through our network of FAA-certified repair stations. Call (904) 998-9101 for testing availability and turnaround times, or submit an RFQ with your specific requirements.
