AIR COM (AC-1) is our next-generation radio module built for small aircraft. It offers impressive sound and advanced functions in a small, lightweight form factor. In fact, AIR COM is the world’s lightest and most compact, fully TSO-certified radio. It sports modern functions like the incredible “Say Again” replay function and separate volumes for the DUAL/MON and the primary channel.AIR COM can be installed directly on an AIR Control Display (ACD-57) or remotely with a cable and mount. It is ideal for light sport aircraft and as it draws very little power and runs for hours on small batteries, it is also suitable for aircraft without an electrical system.Its compatibility with Flight Deck systems like GARMIN® G3X Touch® or Dynon® SkyView® makes it the ideal choice as a second or third COMM in a larger aircraft.    Display and usage The radio is one of the most used instruments during flight. Still, today, most radios feature small displays and often have a cumbersome operation. AIR COM with thr AIR Control Display has the largest display in its class and simple, robust controls that are perfectly usable even in turbulence or with gloves. The color display performs exceptionally well in sunlight and shows all information large and clear. Letters and numbers are significantly larger than in current radios.   Crystal-clear sound: AIR Com's best feature Our AIR Com (AC-1) features an all-new audio design that delivers crystal-clear sound. Its all-digital audio system allows unprecedented functions, like the “Say Again” replay function. Its flexible audio setup allows two independent audio configurations. This is handy in all aircraft where the microphone setup is often changed, such as motor gliders or open-cockpit aircraft.    Frequency Database AIR COM features a comprehensive frequency database. With this database, frequencies can be selected easily by selecting the desired airport or airspace. The database can be updated with the integrated microSD memory card. The integrated memory also allows for storing user-frequencies.   GPS Interface With the integrated GPS interface, a list of the nearest airports or airspaces can be displayed and corresponding frequencies can be easily selected.   Radio and transponder - integration in one device saves space For the first time, it is possible to combine radio and the control of an external Mode-S transponder in a single compact 57mm instrument. To facilitate this, a transponder can be connected to the AIR Control Display. Panel space is precious, displays get larger, and an ever-growing number of instruments need to fit into shrinking panels. Directly connecting the Mode-S transponder to the AIR Control Display means that both instruments together, radio and transponder, only need a single small 57mm/2.25" cutout. This is a big step towards more panel space and saves costs.   Highlights (some of the following features require an AIR CONTROL DISPLAY or a Transponder) Controlling Radio and Transponder in one easy-to-use interface Brilliant, large color display - largest in class, perfectly sunlight readable Easy intuitive user interface Airport Database, GPS Interface, Nearest Frequency Function Frequency/Channel Memory Channel History Dual Watch with separate volume control
