Icom’s A220 panel mount transceiver is a popular fit with experimental and light sport pilots. The TSO approved version will work for all certified part 23 aircraft. This air to ground transceiver has the capability to work on both 8.33 kHz and 25 kHz channel spacing frequencies. It features the brightest OLED (Organic Light Emitting Diode) display on the market offering many advantages in brightness, vividness, high contrast, wide viewing angle and response time compared to a conventional display. The A220 also features a built in 2 station intercom, 12 or 24 volt compatible, and automatic squelch.

Channel spacing: 8.33/25kHz
Channels: 20 regular, 50 group, 10 weather & 20 auto stack memory
LCD display: OLED
FAA TSO certification
The A220 TSO version meets RTCA-160G requirements for use in strict environments. This A220 version can be used for a primary VHF radio in general aviation (part 23) class aircraft. The A220 TSO version is also accepted for ETSO approval under the TSO/ETSO reciprocal acceptance policy.
- For information on what qualifies as a Part 23 aircraft go to the FAA site.
- Environmental Qualification Form
- The A220 TSO version can only be serviced by Icom America Inc. All repairs or adjustment must be performed by Icom America as per the TSO approval requirements.
High visibility & readability
The OLED emits light from organic materials, so a display backlight is not required. It provides an extremely higher contrast and a very wide viewing angle of almost 180 degrees. In addition, the OLED display is set close to the front panel. Well laid out characters help identify important information like operating frequencies. White characters on a black background show clear easy to read operating information. With white key backlighting, the white OLED display matches modern plane’s instrument panel. In addition, the auto dimmer function adjusts the display for optimum brightness at day or night.
The A220’s display has a wide active area, so operating frequencies’ characters can be maximized in the display, while operating status can be shown on both top and bottom. The A220’s OLED can display 4-level gray scale from darker gray to bright white and increases readability. This gradation is used, for example, in showing selected items in the settings menu.
Easy channel selection
It’s fast and easy to select any of memory channels in the A220. The “flip-flop” arrow button switches between main and stand-by channels. The dualwatch function allows you to monitor two channels simultaneously. In addition, the auto stack memory stores the last 20 channels used and allows you to recall those channels easily. All switch buttons and knobs are illuminated with pure-white backlighting that is the same color as the OLED display.
