FlightView Simulator Now Available

We’re getting close to a 1.0 release of the FlightView app. I just pushed the latest beta version to Apple’s TestFlight. It should be approved and available to all beta testers in the next 24 – 48 hours. I’ve had several users ask for a way to see FlightView in action without actually having to install all the hardware. Understandable. Fortunately, using off-the-shelf gear makes that pretty easy.

You can now download an image file that works with any Raspberry Pi 3B or 3B+. Unzip the file and write it to a micro SD card, pop it into the Pi and power it up.

The demo flies a continuous circuit around California through heavy air traffic (300 random simulated targets), through a rain storm, and over some challenging terrain. The emulator sends a constant stream of data for all the key subsystems including the engine monitor, radios, and transponder. To get the full effect you’ll want to install the base map for California and the “US North-West” and “US South-West” terrain images in FlightView. (NOTE: Because of a change in the way we’re handling file access, you will need to install […]

How Not To Install ADS-B Out

Ironically, you might think, I waited until the very last minute to get ADS-B Out installed (well, re-installed) in my RV-6A. The RV arrived back in 2017 with a Dynon system which included Dynon’s (which is actually Trig’s) Mode S transponder. Within a few weeks I swapped out the standard GPS for the 2020-complaint version (SV-GPS-2020) and was fully legal. That worked great until this past summer when I went and ripped everything out to install FlightView. Transponder integration was a long way down the FlightView feature list, so I punted and installed an old but reliable Garmin GTX-327.

Late this fall I finally got around to working on the transponder. It turns that it uses a rather complex low-level protocol called TMAP which both configures and remote controls the transponder. Fortunately, I have friends who are much smarter than I am. With a huge amount of help from Eugene (thanks, Eugene!) I managed to put together a working TMAP implementation. It allows FlightView to do all the transponderish stuff you would expect: squawk, ident, switch from standby to altitude mode. Exciting stuff. So that took care of the transponder requirement. Unfortunately, getting the ADS-B Out feature working was not so […]

Introducing Chekov: Voice Checklists for Pilots

For the past few weeks I’ve been working on an interactive checklist feature for FlightView, our iPad-based EFIS. This checklist feature lets you create lists containing items which FlightView can display and also play as an audio prompt. (Think: “Flaps to 20 degrees.”) You acknowledge the list item by either tapping a button or by saying an acknowledgement word. (Think: “Check” or “Twenty”.) I wasn’t sure how well this would work out, since in most cases speech recognition requires an Internet connection, which can be hard to come by at 10,000 feet.

Fortunately, Apple managed to surprise and delight by introducing a new feature in iOS 13. Offline speech recognition is now a standard feature available on all iOS devices equipped with an A9 or newer processor. This is a game changer: the same technology will ultimately allow us to build a comprehensive voice assistant into FlightView. (Think: “Artoo, plot a course to KRHV” or “Hal, open the pod bay doors.”) Cool stuff!

In the long term this will make FlightView an even better EFIS, which is great. However, the number of people who can use FlightView is fairly limited (for now) so I decided to build a stand-alone app that anyone […]

To Oshkosh With FlightView

I’ve been flying with various versions of FlightView for nearly two years now. When I moved from Kansas City to Cupertino in July of 2018 I had an alpha version running on a RAM mount next to the Dynon system that came with my RV-6A. This gave me a safe and reliable way to test, tune, and validate FlightView. If something didn’t work as expected (which happened occasionally with the early versions) I had a set of instruments to fall back on.

That was a great way to start out, but eventually you have to “eat your own dog food” as they say in the tech world. Over the course of the past year the FlightView software and hardware had matured to the point where I was ready to take off the training wheels, so early this summer I took out the original panel – the Dynon, the steam gauges, and everything else – and replaced it with a dual-screen FlightView system tied to a TruTrak Vizion autopilot.


Before: note the steam gauges and the first-generation 7″ Dynon display.


After: 11″ iPad Pro and 12.9″ iPad Pro, […]

FlightView and Oshkosh

So about the blog… The past few months have been pretty busy, and unfortunately the blog has been a bit neglected. I’m going to try to remedy that starting now. (But you know how life goes.)

Introducing FlightView

You might have noticed the addition of a new product – something called FlightView. If you’re a regular follower of this blog, you might recall a post from some 16 months ago announcing a new EFIS. I think I even used the phrase “coming soon.” Oops. That said, I think you will find it worth the wait.

FlightView is an Electronic Flight Information System (EFIS). That’s a bit of a catch-all term that gets used for a wide range of products. Some are basically attitude indicators with… attitude. Others (like FlightView) could best be described as operating systems for aircraft. They either provide or are connected to every major system on the airframe: flight instruments, engine instruments, navigation, terrain awareness, traffic, weather, communications, and surveillance. They tie all of those systems and technologies and data sources together into a single coherent view.

What’s really cool about EFIS* technology is that, unlike steam gauges or even independent digital instruments, the whole is truly greater than the sum of its parts. […]

California Here We (Finally) Come!

Moving is always painful. For the past month we’ve been operating in limbo while realtors and their clients wandered through the house / shop / office. As you may recall, we abandoned ship for a couple of weeks in May to let them look in peace. Fortunately, that worked and we now have a contract, a moving date, and a new location in Cupertino, California.

That’s the good news. The bad news is that we will be closed for another two weeks while things get packed, loaded, hauled, unloaded, and re-assembled. I have to have everything packed up by next Monday (June 25), so Friday, June 22 is the last day I will be shipping orders until we get thing re-established in the Golden State on or around July 8.

The address for the new location is:

Falken Avionics
10649 Nathanson Ave.
Cupertino, CA 95014

Effective immediately, if you have a system that needs updated or repaired, please send it to the new address. Things sent to the old address may take quite a while to forward.

For everyone impacted by the move, I truly appreciate your patience and understanding. If you make it up to to Oshkosh next month, come by the booth and I’ll give […]

Moving To California

Dear Open Flight Customers,

Several months ago my wife took a job with with a large technology company in the greater Silicon Valley area. I stayed behind in Kansas City, getting the house ready to sell and allowing our daughter to complete her senior year of high school. This weekend (May 13) she graduates. The house goes on the market the next day. As soon as it sells, Falken Avionics will relocate to a new address in California.

I am excited about the opportunity this brings. The Bay Area has a vibrant general aviation community and is the undisputed technology hub for the entire planet. I expect that this move will accelerate a number of projects including the previously announced EFIS.

That’s the good news. The bad news is that selling a house with a working factory in the basement is a challenge. To help expedite the process (and to keep our realtor sane) we are pausing operations for two weeks, starting Monday, May 14. Orders received after May 14 will be processed / shipped the first week of June. During the sale period and subsequent move we will continue to provide technical support using our online trouble ticket system.

I apologize for any […]

New Release With AHRS For ForeFlight

Synthetic vision display.

TL;DR – A new FlightBox update is available that adds AHRS support for ForeFlight and GPS NMEA output over RS232.

Introducing v1.4r4

Welcome to the middle of winter. Things have been rather quiet for the past couple of months, which has allowed us to spend some time heads-down on new features and functions. First among those is AHRS support for ForeFlight*. This has been the number one request since we rolled out the original AHRS support back in March of last year.

The update is available for download from our site or for installation using the FlightBox Utility app. New systems ordered after February 14 will ship with 1.4r4 installed. The code has seen quite a bit of testing from the Stratux community, so it should be smooth sailing under most circumstances.

A few notes on the FF AHRS feature:

Web Interface – To get to the FlightBox web interface, you normally open a web browser and go to 192.168.10.1. Because of changes in the update this might not work in some cases (please see below for geeky details). If you update to the latest version and cannot get to the web interface on 192.168.10.1, try accessing […]

Coming Soon: FlightBox EFIS

UPDATE: FlightView EFIS Is Now Available

For the past two years Falken Avionics has been building and selling the FlightBox line of ADS-B receivers. From the beginning we envisioned FlightBox as the starting point for a much broader set of product intended to reduce costs while increasing safety. While we’re not quite “there” yet, we’re getting close, and I believe this is a good time to share the high-level vision with the aviation community.

In the next several months we will be releasing a set of components that allow homebuilders and LSA manufacturers to assemble a full-featured EFIS with high resolution touch display, precision air data and attitude sensors, comprehensive engine monitoring, WAAS GPS, and dual-band ASD-B for around $2000. Rather than taking the traditional monolithic approach, we’re creating a distributed, optionally redundant network of independent components that provide the full EFIS feature set at a lower price and with greater reliability.

We plan to seek NORSEE approval for these components, allowing them to be installed in certificated aircraft to facilitate better situational awareness and to serve as a backup to legacy instruments.

Please take a few minutes to look over the preview below and let us know what you think. If you’re interested, please

Service Bulletin: ForeFlight Disconnect Issue

Update – 10/25/17 – This morning ForeFlight released version 9.4.3 which appears to have fixed the disconnect issue. Many thanks to the users who helped out by submitting data to the ForeFlight support team, and to ForeFlight for getting this resolved quickly in a point release. -S

We have recently received a number of trouble tickets regarding an issue with the most recent updates to ForeFlight. ForeFlight will connect to FlightBox, but after a number of minutes will display a message indicating that ADS-B has disconnected. Thereafter ForeFlight will usually (though not always) reconnect. This pattern repeats on a frequent basis.

This is a ForeFlight issue, not a FlightBox issue. We have been in communication with the support group at ForeFlight and they have acknowledge that changes to their application, coupled with a number of additional factors (see below) appear to be causing this behavior. This issue also impacts users of the Scout ADS-B receiver and possibly other ADS-B receivers officially supported by ForeFlight, including the Stratus and FreeFlight receivers.

ForeFlight has informed us that they have a tentative solution to this problem will be releasing an update at some point in the near future.  They did not provide a timeline for the update. If a release […]

Introducing FlightBox Pro

FlightBox Pro – FAA Approved For Permanent Installation

I’m extremely pleased to announce that Falken Avionics has received FAA approval for FlightBox Pro, a new version of our FlightBox ADS-B / GPS / AHRS system which can be permanently installed in certified aircraft as a minor alteration. FlightBox Pro, priced at $675, provides weather, traffic, WAAS GPS, barometric altitude, G-force, and advisory attitude data to applications running on tablets, smartphones, and portable navigators. Coupled with a tablet and a mount, FlightBox Pro serves as the core of a powerful yet inexpensive MFD.

FAA approval means that FlightBox Pro can be installed permanently: mounted to the airframe; wired to the avionics buss; connected to external ADS-B and GPS antennas. A permanently installed system is more convenient, reduces clutter in the cockpit, improves ADS-B and GPS reception, and provides more accurate AHRS and G-meter functionality. Installation can be done by any licensed A&P mechanic or repair station. The process typically takes one to two hours – less if you have existing antennas. The FAA approval permits the installation of FlightBox Pro on any Part 23 / CAR3 airplane and any Part 27 or Part 29 rotorcraft. […]
