Garmin once again placed at the top of AIN’s latest Avionics Product Support Survey, scoring an 8.3 rating (out of a possible 10) this year from AIN readers–the same as last year. L-3 Avionics and Universal Avionics tied for second place, both with 7.8 ratings. L-3 moved up two spots in the 2014 survey ranking, with a half-point jump from last year’s fourth-place rating of 7.3. Universal Avionics also placed second last year.

Nipping at their heels was Rockwell Collins, which moved up a tenth of a point to 7.7 this year for third place–the same spot it held in last year’s survey. Honeywell’s fourth-place ranking this year is one place higher on the list and a climb in its rating to 7.4, from 7.1. In fifth place this year is Avidyne, which saw its rating drop to 7.2, followed by Honeywell’s BendixKing subsidiary with a one-tenth-point increase to 7.1.

High scores in the rankings categories went across the board to Garmin for parts availability (8.5), cost of parts (7.6), AOG response (8.2), warranty fulfillment (8.5), technical manuals (8.1), technical reps (8.3) and overall product reliability (8.8).

On the cabin electronics side, AIN readers ranked Aircell (now Gogo Business Aviation, see Also Noted at left) as the top provider of product support with an 8.2 rating, followed by Satcom Direct at 8.1. Rounding out the top four for cabin systems support were Honeywell and Rockwell Collins, with ratings of 7.3 and 6.7, respectively.
