The ACK A-30.9 (Mod 9) Altitude Encoder is a solid-state pressure altitude reporting device designed to supply accurate digital altitude data to modern aircraft avionics. Equipped with two independent RS-232 serial outputs, it allows simultaneous connection to multiple systems such as transponders, EFIS displays, or other compatible avionics.
By converting sensed static air pressure into ICAO-compliant pressure altitude data, the A-30.9 supports reliable Mode C and Mode S altitude reporting. Its dual-output configuration makes it particularly well suited for aircraft with integrated avionics suites that require shared altitude data without additional signal splitters.
Manufactured by ACK Technologies, the A-30.9 (Mod 9) is engineered for aviation environments and offers the benefits of solid-state design, including reduced maintenance and improved long-term reliability. Installation is performed in accordance with applicable aircraft approval data and manufacturer instructions to ensure compliant and accurate operation.
