Avionics OEMs continue to work hard to bring innovative and reliable products to the cockpit which enhance safety and facilitate operations. Product support from the manufacturer is an important factor in this equation, and enables successful operations with no interruptions.

For the 26th year, Pro Pilot asked operators to rate avionics manufacturers and share their experience of OEM assistance by means of its 2021 Avionics Product Support Survey. Ranking and narrative commentaries follow. 

Garmin keeps the crown for the 17th year, obtaining an overall score of 8.66 – an increase of 0.19 from last year’s score of 8.47. Garmin places 1st in all survey categories with improved scores this year.

Best category increase was in tech reps, with 8.68 this year, compared to the 8.32 score received in 2020. Garmin’s Aviation Support Center is ready to answer any questions and provide solutions to help operators complete their missions.

Universal Avionics receives 2nd for the 13th consecutive year, earning an overall score of 8.33 – an improvement from 8.21 in 2020. Universal obtains the 2nd spot in all survey categories, except for speed in AOG service, where it places 3rd.

Best category score increase was in cost of parts, with 7.39 this year, compared to 6.74 in 2020. This 0.65 increase is also the biggest in the entire survey. Universal also had a significant improvement in manuals or CDs, with a score of 8.04 this year – a boost of 0.41 from 7.63 in 2020.

Universal Avionics operates a worldwide network of regional offices, FSRs, service centers, and repair stations to solve issues and answer operators’ questions.

And UniNet, the company’s online service center, makes available navigation databases and downloads, tech manuals and publications, support requests, online training, and invoice payments, while also providing solutions to  other operator needs. 

Collins Aerospace retains the 3rd position for the 13th year in a row. Overall score this year is 7.98, compared to 7.88 in 2020. Collins places 2nd in speed in AOG service, and 3rd in product reliability, tech reps, and support from manufacturer.

This OEM’s best category increase is in manuals or CDs, with a score of 7.67 – up 0.30 from 7.37 from 2020. Collins Customer Service global service networks, as well as the Collins Aerospace Portal and UTC Aerospace Systems Customer Portal, are available 24/7 to deliver the necessary support from technical publications and bulletins, account information, order status, up-to-date information, and services.

Honeywell rounds out the survey by taking 4th place. Overall score this year is 7.87 – up 0.23 from 7.64 in 2020 – and represents the largest overall score increase in the survey.

Honeywell takes 3rd spot in both the cost of parts and manuals or CDs categories. Best category increase was achieved in manuals or CDs, with a 7.93 score – a difference of 0.58 from 7.35 last year, and the 2nd biggest category improvement in the entire survey.

It also demonstrated a notable improvement in tech reps, with a score of 8.25 this year – up 0.42 from the 7.83 earned in 2020. Honeywell is available to provide technical support and customer assistance, and to solve AOG situations. Honeywell’s Aerospace Portal enables operators to access solutions to continue flying.

Prodigy Touch avionics suite for the Phenom 300E is superb, and it’s backed up by great product support. Garmin provides very reliable systems, and AOG parts are normally available in stock.

I find the Garmin G5000 to be an amazing flightdeck. It’s reliable  and lightweight, it gives off low heat, and it’s easy to use.

The Garmin G5000 in our Citation Sovereign+ works very well. It has a nice cockpit presentation. On the other hand, I believe that Garmin’s customer service via phone could be better.

Garmin can be a little slow to acknowledge issues. However, once they’re convinced that shortcomings in their systems are not pilot error issues, tech reps resolve them very quickly and thoroughly.

In my opinion, Garmin G3000 is a good avionics system for the Phenom 300E. When Embraer releases the new software update, it will be even more capable, with additions like visual approaches to all airports. However, something that needs updating is the training manual. It’s severely out of date and has little value to the user.

Garmin does a real good job with its products. The G3000 installed in our Phenom 300 is very robust and user-friendly. Could use some improvements, but I think they know that and are working on them.

Our upgrade in the Citation V to a WAAS-capable Universal UNS, performed by Textron Service Center SMF (Sacramento CA), came off without a hitch. The new LPV-capable UNS has been working as advertised, and the FMS operational class offered by Universal as part of our upgrade is much appreciated.

We upgraded our King Air 350 in 2017 with the Universal UNS-1Lw. It’s very user-friendly and has every function that we need for the operation of our aircraft. Its reliability is fantastic. The unit we replaced was the UNS-1K, so the transition was easy. Our UNS-1Lw is much easier to use than other units.

We have Collins Pro Line 21 installed in our King Air 350 and Hawker 850. And, in my opinion, it’s one of the most intuitive systems to use in flight.

Our Challenger 605 has the Collins Pro Line 21 installed. It’s been very dependable and pretty much trouble-free. We’re pleased with it and have had few issues during the 8 years we’ve operated it.

We upgraded our Challenger 604 to Collins Pro Line Fusion. The avionics package is excellent, but the company has been substantially late to provide performance data as part of the package, which is critical for all phases of flight. Collins continues to push out delivery dates for when this feature will be available to customers, but we need to have full functionality of the Pro Line Fusion suite.

transitioned from a King Air C90 Pro Line 21 avionics suite to a King Air 350i Pro Line Fusion, and support from Collins has been satisfactory. The Pro Line Fusion works well once patterns are developed for entering and obtaining information.

Pro Line Fusion brings an impressive  amount of situational awareness to the single-pilot cockpit. And I’ve been very pleased with the support from Collins. I only wish our Pro Line Fusion also came with XM Satellite Radio for my listening pleasure.

Honeywell Primus Epic for the Falcon 2000EX EASy II is exceptional. We’ve had very few problems, and, when an issue arises, it’s usually resolved among tech reps and Honeywell’s call center within a day.
