Airborne APRS Suggestions

> Above altitude of 3000 feet one should use at most WIDE1-1, preferrably no via paths at all.

>> Bob should really write some new guidance on path definitions for flyers.

The recommendation has never changed in the last decade.

NEVER-EVER USED WIDE1-1 !!!! There is no DUPE suppression in APRS for WIDE1-1!.

For BALLOONS, the recommendation is to use a payload with variable paths and rates at altitude and on the ground * OR * if a less-smart payload is used, use WIDE2-2 and no more often than 1 minute. This is not as bad as it sounds. Every digi will ONLY DIGIPEAT IT ONCE (not twice or more) because the New-N paradigm eliminates dupes. And having a new "vehicle" appear in every digi area for a 3 hour mission special event, is no worse than another driver driving though the area.

If a DIGI is causing dupes, FIX THE DIGI! Update to the 2004 New-N Paradigm!!! See http://www.aprs.org/fix14439.html

For Aircraft, the PATH is WIDE2-1. There is no reason to need 2 hops on the ground. The plane should not be lost...

NEVER USE WIDE1-1 on any airborne mobile.
