Default Kwik EFIS for Android Released

I am pleased to announce that Kwik EFIS has been accredited and accepted as Free and Open-Source software (FOSS) by F-Droid.

Thus, the Kwik EFIS package will now also be available from the F-Droid catalogue at:

https://f-droid.org/repository/brows...layer.efis.pfd

The current released version is 2.4. It features the portrait mode and the HITS navigation display.



Changelog
=========
2.4 (2014-03-17)
------------------
* Waypoint database cycle 2017-03 (usa.can)
* Change bank/skid correction filter constant
* Add automatic de-clutter to HITS

Users may want to install the F-Droid catalogue application as well. It provides a most excellent Free Software portal similar to the Google Play Store.

F-Droid provide easy access to a variety of great FOSS software and a easy mechanism updating your installed apps.

Default Kwik EFIS - Q&A

On to comments and more questions....

When I first loaded it on my phone, I still had a couple of red X's on the display. Finally figured out that if you're not moving, it thinks (knows?) something isn't right. :-)

What would you consider to be a 'comfortable' level of processing power & gyro/accelerometer quality for smooth, reliable operation? Component ID's are fine, but brand/model of phone or tablet would be even better for the lazy (me) among us. Would a 1st gen Nexus7 be adequate? 2013 version? What about some of the phones that are a few years old, like the Galaxy S4 or similar?

Thanks,

Charlie
Red X's
-------
You are quite correct. The speed has to be non-zero (from memory I think the threshold is 1 m/s). There are also different behaviors below and above the stall speed, which is why it is important to choose a suitable aircraft model in the "Manage" section.

Demo Mode
-----------
In order to practice with the program, enable the "Demo Mode" and it will simulate movement allowing you to use it like a simple flight simulator.

Hardware
---------
I have used the original Nexus7 (2012?) for all the development and testing. It is adequate, but is the minimum I would use. I tested with a Samsung S2 phone and that was close, but not quite good enough to be useful. I have been told that the later models of Samsung S 4/5 works well, but I have not had the opportunity to test for myself.

Default Kwik EFIS - Startup

Hi Charlie,

The Kwik EFIS app will not run at startup. You need to start it like any other app and once you exit the app it is gone. No background processes at all.

To be as accurate as possible, the app does however use the maximum performance from the GPS when it is running, there is no way around that.

The to 'run at startup' handler code exist in the program and is therefore reported, but is not used and is disabled in the manifest. The 'run at startup' handler is only used in a dedicated version of Kwik EFIS when it is intended as the only app running on a permanently installed device. Ie Kwik EFIS will start running when the device is powered on.

It has been a pretty eventful time in terms of Kwik EFIS development. The application now features much improved synthetic vision performance, much more coverage and also voice alerts.

Would you you believe it! We have gone international. In addition to our Ozies and Saffers, we now have American, German and even Russian (Спасибо, Юрий) users.

Kwik EFIS V3.2 has been flight tested and the stable (unsigned) release candidate can be downloaded from:
http://ninelima.org/efis/download.html under the Beta Releases.

Note:
This version of Kwik EFIS has also been released to F-Droid for signing and distribution. There is a unfortunately bit of a technical delay with the data pacs. Hopefully this will be resolved soon and signed app and data packages will be available from F-Droid as a signed and certified package.
(See https://gitlab.com/fdroid/admin/issues/31 for details)

Default Kwik EFIS release candidate 3.10 is now available.

Current Release 3.10
Due to a common request and with some help from the XCSoar project, I have implemented a High Contrast themes for the Kwik EFIS suite.




It should improve the screen readability in direct sunlight on some Android devices. This release also has the fully terrain aware DMAP. YELLOW indicate less then 1000ft and RED less then 100ft. Use the simulator to play around with the application and get a feel for how this works.

Auto Zoom is also now also finally functional and is enabled with a horizontal swipe. Zooming IN and OUT (with a vertical swipe) disables auto zoom.

Data Pacs
The initial data pac for South America, Panama to Argentina, (data.pan.arg) has finally been released. It should be available on F-Droid in a few days. Check https://f-droid.org/wiki/page/player.efis.data.pan.arg

Work In Progress
Work is currently underway to port the Kwik EFIS to an E-Ink readers (Kobo etc). This is however still a ways off from public release. In the mean time, please do have a look at XCSoar. While it is intended mainly for our gliding brethren, it is nevertheless an awesome piece of work.

Download Details
I develop and maintain a small suite of aviation related of Android applications named Kwik EFIS.
It is distributed under a Free and Open Source (FOSS) license in the hope that it would be useful to fellow flyer's.

The Current work in progress candidates (unsigned) are always available, from:
http://ninelima.org/efis/download.html

All artifacts of Kwik EFIS are also released to F-Droid for FOSS certification, signing and distribution.

https://f-droid.org/packages/player.efis.pfd/
https://f-droid.org/packages/player.efis.mfd/

It normally takes a couple of days for applications to be processed by the volunteer staff at F-Droid. The signed applications and data packages will be available at the above links when ready.

Default Feature request

Not sure if this is the right place, but I'm wondering if you have a database of frequencies, and if so, if you could have a feature that shows you what frequency you should or could be talking on - perhaps even an ordered list. Thanks.

The short answer is no.

The longer answer is that I did and still am considering something like it. It is a little bit tricky though, since there can be a number of valid frequencies at any given time for any given porition. Which one to show? Destination, Closest airport, Centre, AWIS, ATIS, etc.

I also deliberately keep user interaction to an absolute minimum, which is why the idea of a list does not really appeal to me.

Having said that ... the entire code-base including all the current databases are available on github and the development tools are available for free from Google. I would encourage everyone to fork the project and have a go at implementing new ideas.

Hey Dave,

I'm revisiting the Kwik EFIS app, in light of recently hearing about the AHARS features in newer Stratux hardware. Any chance there will be hardware in the future that will add true air data?

Also, is there a home on the interwebs where users are discussing installations/operation/etc?

Thanks,

Charlie
