Meet the AIR Control Display 57 (ACD‑57), a compact multi‑function panel instrument that integrates COMM radio control, a certified primary altimeter, and transponder control into one intuitive display. The vibrant 2" colour screen is perfectly readable in sunlight and adaptive for night use. With its minimal weight and power draw, ACD‑57 is ideal for small aircraft, light sport, gliders, or even battery‑only installations.
Depending on installation, the interface automatically adapts: when controlling only a radio, it shows active/standby frequencies in huge letters; when a transponder is connected, it displays the squawk code in large digits along with mode (e.g. ALT) and flight level. Altimeter mode shows a tape‑style indication with a fine vertical resolution. You can combine any of these three functions on a single ACD, making it the most space-saving, fully TSO-certified solution on the market. Its unique functions include GPS-based functions like a database‑driven “NEAREST” list of COMM stations and station names for easy identification of tuned-in frequencies. Four pushbuttons and a large dual rotary knob make the operation easy, even in the most turbulent conditions and when wearing gloves.
To enhance the core functionsailty of ACD-57, add-on functions can be purchased. In addition to AIR Avionics' own radios and transponders, ACD‑57 supports third‑party systems. It plays well with leading compact-class COMM and Transponder systems by uAvionix, TRIG, FUNKE, Becker, and TQ. Additionally, ACD-57 can be connected to flight decks and EFIS systems for external control. All these interfaces, combined with the ability to install any number of connected ACD-57 in an aircraft, make this little device a true cockpit powerhouse.
