I finally had a chance to fly with the GTN750 today.
It’s quite obvious that Garmin took their time and sought input from pilots when developing this system. As we all know, manufactures and software developers don’t always take users into account when designing new systems and we are often left scratching our heads why things were designed the way they are. I am happy to report that Garmin put a lot of thought into the new system. The functionality is well thought out and easy to work with.
My initial impression was the screen. It’s big, bright and extremely sharp with excellent color presentation. I liken it to looking at a high resolution photo on an iPad. When moving along, the "ownship" symbol moves smoothly along the route, not the every second update where it "jumps" to the next position as on all other systems.
Entering a flight plan is as simple as Garmin portrays it in their promotional material. Either go to the flight plan page and enter the waypoints manually (by punching in the identifiers) or drag your finger along the screen to the place you want to go, with points along the way. I entered a simple flight plan manually and decided to insert a waypoint by simply dragging by finger and “rubber banding” the new point. I then pressed a button on the screen and it was inserted effortlessly.
When asked what the best part of the system is, I would say it’s the wealth of information displayed on the map page. For those installations like mine which do not have the integrated transponder and audio panel, the top portion of the screen displays all of the information that you are accustomed to on the 4/530W from the default navigation page, such as the Desired Track, Distance, Speed, ETE as well as a CDI. This does not show up in the Garmin promotional material because they are always displaying installations containing the remote transponder and audio unit, which displays their own related set of goodies occupied in the same space at the top of the display between the COM and VOR frequencies.
Another great thing in addition to the default navigation information is the ability to select other information that you want displayed. The screen has four data fields which you can customize simply by touching the field on the screen and selecting the item you want displayed from a long list of 24 different choices. This is a great feature. But better yet, for those of you that share the plane, you don’t have to live with the default values somebody else setup. On the GTN you can set them on the fly. No more wading through multiple levels of confusing menus to get the items you want.
The ease of use is something one has to see to believe. You are never more than one key away from the menu. The number of setup options is impressive and it’s very easy to customize things to just how you like them, right down to the volume of the touch screen clicking sound. Well done Garmin, well done.
Selecting frequencies is a blast. Bring up the airport and touch the frequency tab to display a list of frequencies. Tap on the one you want and it’s placed in the standby corner.
My brief flight did encounter slightly choppy air and entering information didn’t prove much of a problem. I also employed use of the concentric knobs for entering frequencies manually to see how well it works.
I think the people from Kansas have a real winner on their hands. The only thing conspicuously missing is a reminder to switch tanks. I looked high and low and couldn’t find it. I know there are some customizable timers so that may work somehow.
More to come.
