[aprssig] Low Alt aircraft path

I know it is “APRS blasphemy” to suggest this, but we have found that for airplane travelers in California, a digipath of only WIDE1-1 at a conservative timed interval (like once every 2 minutes) does the trick best, around airports and at altitude.

I can't speak for the MT-AIO but I know that the Argent Data trackers have profiles that can be used to change path settings based on altitude, position, etc.:

I have a ham friend with a MT-AIO that he wants to use in his airplane.  He states he usually operates at 1-2,000 Ft AGL.  We have discussed the issues that have come up with high altitude balloons.  He understands to NOT have WIDE1-1 in the path for this application.

His research is pointing him to WIDE2-1.  Given the number of Digi's in the area, I wonder how no path would work.

One of his concerns is that some of the small airports he uses away from home are in areas without Digi coverage at ground level and thinks that no path would not allow him to get a packet out when landed and parked.

I have suggested programming each configuration available to him with a WIDE2-1 and no path.

Comments, suggestions?

Thanks in advance
