Garmin once again has claimed the top spot for cockpit avionics manufacturers in the AIN Avionics Product Support Survey, with an 8.3 overall average, the same rating as last year and more than half a point higher than the nearest contender. On the cabinelectronics front, Aircell also retained its lead with the same rating as in the 2012 survey, an 8.0. In both categories, companies that weren’t rated last year (listed as N/A) received enough ratings (20 minimum) to be added to the 2013 results, including L-3 Avionics, Rosen Aviation and Lufthansa Technik.

Moving up to second place this year in the cockpit avionics category are Avidyne and Universal Avionics (tied with 7.7). This is the same score that Universal received last year for third place, while Avidyne’s score climbed this year to 7.7 from 7.5 last year. Rockwell Collins dropped slightly this year to third place with a 7.6, down from last year’s 7.8.

L-3 Avionics received enough reader ratings to be listed on the results this year and came in at fourth place with 7.3. Honeywell and Honeywell’s Bendix/King division received 7.1 and 7.0 respectively this year, down from last year’s 7.5 and 7.1.
