Meet the latest edition of Dynon’s popular portable EFIS line - the D3 Pocket Panel. Featuring improved brightness, a new intuitive touchscreen interface, new synthetic vision display, and an even lower price point, the D3 is the most advanced portable safety device Dynon has ever made.

D3 lets pilots supplement their unreliable legacy instrumentation with an affordable, portable electronic attitude indicator that works. The D3 features the same reliable, proven AHRS engine from Dynon’s best-selling panel-mounted products for experimental, light sport, and type certificated aircraft.

The D3 comes with a complete set of accessories, including home and airplane chargers, an optional external GPS antenna, and two unique mounting options. Both the included cockpit mounting options require no tools, allowing the D3 to be deployed in any aircraft with no FAA approval. The first mount included is a RAM® suction cup mount. The second is a 3-1/8" portable "pinch" mount that allows the D3 to be easily mounted in an empty existing instrument panel hole without any fasteners.

The D3 Pocket Panel is a portable situational awareness device, allowing pilots to add a modern, affordable backup safety device to supplement their often unreliable legacy certified instrumentation. The D3 comes with two portable mounting options, no tools required. Because it does not require modification to the aircraft's design, no regulatory approval is required to use a D3 Pocket Panel in any aircraft. The first mount included is a RAM® suction cup mount. The second is a 3-1/8" portable "pinch" mount that allows the D3 to be easily mounted in an empty existing instrument panel hole without any fasteners.ted in an empty existing instrument panel hole without any fasteners.

I did not install it into the aircraft yet, only used it in the car and it works perfectly there. great features for a small device. the attached mounting tools are excellent.

Great backup for my steam AI. Mounted it in my Cherokee directly in front of me so it requires no looking down while flying. Well made product.

I am very pleased with my Dynon D3 portable horizon. It was an easy setup and has worked flawlessly. I wanted more than a Turn and Bank indicator in my Citabria. The Dynon D3 has filled that safety gap perfectly!

The Dynon D3 improves pilot outside the cockpit situation awareness of terrain, obstructions and weather with synthetic terrain and GPS aircraft attitude. The synthetic terrain supplements chart terrain information and compliments reliable steam gauges with GPS orientation. It is cold-rated for Alaskan winter temperatures that is very easy to understand and use, and it appears reliable and well designed. It is not a cockpit distraction.

Good value. Quick delivery and quick setup. Tested in a C160 Im training in, alongside the installed Garmin G300, before installing in my homebuilt. Response times and behavior appear identical. GPS reception appears good without the external antenna no issues with running it with or without that. Daylight visibility is good. Have not used the secondary functions in flight. Have not tested the full battery life. Two different mounts are good. The price point is good. Was considering a Garmin G5 but dont really need the additional functionality in that unit and the additional cost to get it all. Also, fifty bucks to the Aerospace Center when they need it is a bonus. Definitely recommend where appropriate.

I had purchased the Dynon D2 and while its performance was satisfactory the screen brightness left a lot to be desired and with the Garmin G5 having come out the D2 was inferior in my opinion. Recently my future son-in-law planned an avionics update for his Cherokee 235. The original plan was to go with Garmin, however, only designated facilities were allowed to do the install so we looked at Dynon and they have it right. Price, performance and the ability to allow an A&P/IA do the installation. That led me to the purchase of the D3 which will be used in a Zodiac 601HD but secondarily as a backup to a Cessna 182. The D3 is far superior to its predecessor and offers performance at a competitive price.

Q: Can the Dynon D3 pocket panel be permanently wired in? Can the D3 be flush mounted?

This unit operates on 5v power, and the cigarette power cord is included in the box. There is a 3-1/8" portable "pinch" mount that allows the D3 to be easily mounted in an empty existing instrument panel hole without any fasteners.

Q: Regarding the Dynon D3 pocket panel portable EFIS: 1. When fully charged, how long is the internal battery supposed to last before having to reconnect to a power source? <br> 2. In the product picture it appears that there's a 12v plug that has 2 USB ports for plug ins? Am I seeing that correctly? <br> Looks like a great unit with excellent color graphics on the screen.

The unit comes with a cigarette charger and wall charger in order to charge the unit's battery. The battery can last up to and exceed 8 hours on a single charge, but this can vary greatly depending on your usage of the unit.

Q: Can the Dynon D3 pocket panel be used in a 1966 Cherokee 140?

The Dynon D3 is a portable product, and it does not hold an FAA TSO. However, it can be used in certified aircraft application but does not replace any primary or panel mounted instruments.

Q: Is SynVis supported outside the US on the Dynon D3 portable EFIS? Is it a subscription-based data product, and if so, what is the cost?

Per the manufacturer, this will work outside the US as the D1 and D2 did. The subscriptions are for the databases and can be downloaded through the manufacturer.

Q: Does the Dynon D3 EFIS have an internal data base for the synthetic image of the terrain for South America?

The synthetic vision is drawn based on a world-wide elevation database stored in the device. It does not include features such as airports.

Q: Can the G-meter red and yellow ranges be adjusted? Let's say my airplane is rated to Plus 6g's and minus 5 g's. Is there a setting to change the display on the Dynon D3?

Yes. The caution (yellow) and warning (red) ranges are selectable from the settings menu in 0.1 G steps.

Q: Is there a possibility to display the magnetic heading on the Dynon D3?

Per Dynon: the D3 can not display magnetic heading.

Q: Does the D3 require gps input to provide attitude info i.e. Pitch and roll? I know the other functions require gps but i am asking is the mems based attitude standalone without gps input? I returned an earlier D1 that required gps for attitude and did not work well.

The D3 has an internal GPS receiver, which will allow these functions to work.

Q: Can the Dynon D3 GPS speed be changed to Miles Per Hour? How is the Altitude calculated? Do you set the ATIS numbers as you would on your Altimeter to maintain accuracy?

You can set the barometric numbers for accuracy and the unit has sensors for altitude. As for the ground speed you are able to select MPH.

Q: If the Dynon D3 looses GPS signal, will it still display accurate pitch and roll information, or must it have constant GPS coverage to provide pitch and roll?

Per the manual, GPS is required for the attitude to work properly.
