Garmin is once again the Overall Average leader in the Flight Deck Avionics segment in AIN’s 2021 Product Support Survey, with readers giving the Olathe, Kansas-based avionics manufacturer a rating of 8.6, followed closely by second-place finisher Collins Aerospace’s rating of 8.3 and Honeywell’s 8.1 rating. Universal Avionics’ 8.2 rating, a 0.1 decrease from last year, is broken out separately as the number of responses fell just below our threshold for comparison with the other OEMs.
In the Cabin Management Systems (CMS) segment, Honeywell led with an Overall Average rating of 8.3, with a tie for second place between Collins and Gulfstream Cabin Management, each of which received an Overall Average rating of 7.9—a 0.1 increase for Collins but a 0.4 decline for Gulfstream. New to this year’s CMS listing is Cessna/Beechcraft Cabin Management, which earned a 7.8 Overall Average for a third-place finish, ahead of Lufthansa Technik at a rating of 7.4.
In the new Airborne Connectivity segment, Gogo Business Aviation was the top finisher with an Overall Average of 8.5, on par with AIN readers’ rating of the Broomfield, Colorado-based company last year in the Cabin Electronics segment. Honeywell was just behind at 8.3, a 0.2 gain from last year. Satcom Direct finished third with an Overall Average rating of 8.2, which was 0.3 lower than in the 2020 survey. Collins received an 8.3 rating, up from 7.8 a year ago but with a smaller number of respondents preventing direct comparison with the other OEMs.
