Hi John,

I am still in the dark about the actual implementation. As I asked before via mail what is your position on the following features of XCSoar:

* AH based on GPS/Vario/Airspeed
* AH based on internal/external gyro (forbidden, but not implemented in any version of XCSoar yet)
* METAR download (forbidden, right? how is it different from requesting it via VHF?)
* Live Tracking via 3G/4G (only upload, no download)
* Flarm radar functionality

Does the application need to make sure that data/voice services are not used? Is it enough to enable the plane mode in the smartphone? I wouldn't know how our software should be able to block incoming voice calls which are not part of our software...

Hi Tobias,
WRT US Rules only:
1. AH based on GPS/Vario/Airspeed - although unlikely this can be
effectively used for cloud flying still not allowed.
2. AH based on gyro - not allowed
4. All incoming data stream based weather data is forbidden,
regardless of the technology (cell,satellite, VHF, VLF). Listening to
non-specific voice broadcast (e.g. ATIS) is ok,
5. There is no current restriction on Flarm radar functionality but be
aware this may change next year.
