Vifir should be suitable for normal use, however USE AT YOUR OWN RISK. Testing and bug reports are encouraged.
We are proud to announce the release v0.7. This release adds improved support for the latest versions of gpsd.
Vifir is released and distributed under the Open-Source GPL v3 license. Note that there is NO WARRANTY and that Vifir is NOT an FAA-approved Electronic Flight Bag (EFB).
A small archive (~20M) of sample data may be downloaded here and installed using the "Import" option in the Data Manager.
Vifir is compatible with the flight database, sectional charts, and approach plates available at naco.faa.gov and the airport data from data.x-plane.com.
Vifir uses gpsd for GPS support. Once you get it working with gpsd it will automatically work with Vifir.
To begin with, the following should not be construed as legal advice. Consult a qualified aviation lawyer or Certified Flight Instructor for their opinions.
As of June 2008 there is no requirement in FAR part 91 (General Aviation) for any particular navigational chart to be on board. Pilots must be familiar with "all available information" and the use of portable electronic devices is up to the Pilot in Command.
The data used by Vifir is provided by the National Aeronatical Charting Office, which is the same people that produce the paper charts.
Vifir is NOT an approved Electronic Flight Bag and does not meet the charting requirements of FAR part 135.
The data provided by Vifir should be considered as an aid to situational awareness, just as with any portable GPS device.
This is FAA (NACO) policy for their digital chart products.
See the Obtaining Data section above.
NACO distributes these as PDF files that aren't georeferenced - as a result they are not currently supported.
The code for Vifir itself should be able to be ported quite easily. Vifir relies on a number of libraries - porting them to Windows is a significant challenge, though certainly not impossible. Anyone who would like to work on this is encouraged to do so.
