Congratulations to Garmin on introducing the G1000 ten years ago. I bet most readers are surprised that this wildly successful glass cockpit has been around so long. If you still haven’t flown one of these fun systems yet, don’t let another ten years slip by before you do!
A Brief History
Rarely in the last fifty years has General Aviation experienced such a tidal wave of change. In only two years, the industry converted nearly 100% of piston aircraft shipments from round gauges to glass cockpits. And for the first time, it meant that a student pilot could learn behind the same glass panel that he or she might later use in a jet!
Cirrus and Avidyne led the revolution in 2003 by adding a PFD (Primary Flight Display) to the MFD (Multifunction Display) that already shipped in the SR20 and SR22. That glass cockpit system, the Avidyne Entegra had its greatest success at Cirrus until the Cirrus Perspective, a G1000 derivative, debuted in the SR22 in May 2008.
The Garmin G1000 was first shipped in a Diamond DA40 in June 2004. Meanwhile, in Independence, Kansas, nearly completed Cessna 182’s were filling the ramp as the factory awaited their G1000 deliveries. The first Cessna 182/G1000s were delivered in July 2004 and 172s began shipping with the G1000 in early 2005.
By mid-2005, five aircraft OEMs including Cessna, Diamond, Beechcraft, Mooney, and Tiger announced shipment of the Garmin G1000 in most of their piston aircraft. Columbia, which previously offered the Avidyne Entegra in their 350 and 400 aircraft, converted to the G1000 in early 2006, though not without a major problem from Mother Nature. Nearly 50 new Columbias were parked outside the factory, all awaiting delivery of G1000 systems, when a freak hailstorm pelted the planes. Months were spent quantifying the damage and determining how and if to repair the composite wings, which had hundreds of micro dents from the hail.
Reading or hearing about a glass cockpit for the first time is akin to reading or hearing about EAA’s AirVenture at Oshkosh. Until you actually experience it, it’s hard to imagine just how great it is and how much it will exceed your expectations.
I was initially skeptical when I read magazine reports about the then new G1000. I’d spent 25 years working in the high technology industry, where occasionally I saw technology thrown at problems that could have been solved in simpler ways. So when I first read about the G1000, I recall thinking “What a waste of a computer,” to install one in the instrument panel of a GA aircraft. How wrong I was.
By early 2005, curiosity led me to get an hour of dual instruction in a G1000-equipped Cessna 182. Immediately I knew it was different, but I didn’t want to rush to judgment until I’d had time to reflect on the experience.
I wrote about my conclusion in Max Trescott’s Garmin G1000 and Perspective Glass Cockpit Handbook:
“The single biggest benefit of the G1000 and Perspective, compared to competitive products, is that it allows you to aviate, navigate and communicate from a single 10-inch or 12-inch display. In contrast, competitive products have pilots looking in multiple places to see data and reaching in multiple places to operate controls.”
Having your eyes near the primary flight instruments all the time reduces the odds of entering an unusual attitude while tuning a radio or entering a GPS flight plan. Plus, the 10-inch wide artificial horizon is far superior to the 2-inch airplane symbol found in most round gauge attitude indicators. But that’s just the beginning. Glass cockpit aircraft contain many safety features, like traffic, terrain, and weather information that have the potential to reduce accidents when pilots are trained in their use and use them properly.
Glass cockpits have also changed the paradigm for avionics. Historically, avionics stayed on the market for many years with few changes until entirely new models replaced them. Quoting again from my G1000 Book, “The G1000 system clearly breaks this paradigm. First, with two large software-driven displays, new features can be continually be added to the G1000 in far less time than it took to design, manufacture, and release traditional avionics…The Ethernet bus architecture also makes it easy for new devices to be designed and connected to the G1000.”
But if engineering school taught me anything, it was that there are tradeoffs in every design decision. Today’s new computer and software-based avionics, as good as they are, occasionally suffer from the same woes seen in the computer world. For example, one time a Columbia 400 equipped with TAS, an active traffic system, came back from maintenance with TIS, a less capable traffic system. It turned out the maintenance personnel forgot to reload the software for the TAS system, so it effectively disappeared!
So where are we headed? Undoubtedly, Garmin will pack a few more new features into the G1000 and Perspective through software upgrades and possibly more hardware additions. So existing owners can expect some new features. Eventually the speeds of the now ten-year old processors will limit upgradability. But it is a modular architecture, so Garmin might in the future offer new hardware modules to provide G1000 and Perspective owners with an upgrade path that adds robust new features.
The G1000 and Perspective may appear in a few more aircraft types, possibly as retrofits to older turbine and jet aircraft and perhaps in a few new aircraft types. But Garmin now offers the G2000, G3000, and G5000 on the high end and the G300 on the low end, so that keeps the Garmin G1000 from moving up or down into these markets. I don’t expect to see the G1000 being retrofitted into many older single engine piston aircraft. With the average age of the GA fleet approaching 40 years, the cost of the upgrade would exceed the value of most of these planes, so the market opportunity is too small for Garmin to pursue. However these older aircraft are an excellent target market for partial glass cockpit upgrades using solution like Aspen Avionics and portable iPad solutions.
Of course someday the G1000 will be replaced with something new. The workhorse Garmin 430 shipped for about 14 years. But the G1000 is more upgradeable, so it could conceivably have a longer product life cycle. And there’s always the possibility that Bendix/King, or another competitor, could introduce a new product that replaces the G1000 in a future refresh of new aircraft cockpits.
The impact of the G1000 and other glass cockpits cannot be overstated. For years, airline pilots told me the G1000 “was better than what I have in the airliner I fly.” But sadly, glass cockpit-equipped aircraft are still a small fraction of the overall GA fleet, partially because of the slowdown in new aircraft sales since the 2008 recession. Most pilots still aren’t flying in them and thus aren’t benefiting from their safety advantages.
So on the tenth birthday of the G1000, we should thank Avidyne and Cirrus for starting the glass cockpit revolution in GA aircraft, and thank Garmin and Cessna for making it such a widespread phenomena. Kudos to all of these companies for their great work! Now let’s get started on the next revolution in General Aviation…What do you think it will be?
