After reading through the rules it is my assumption that both SPOT and APRS systems are allowed.

I wondered about that. What commercially available device performs
the complete APRS function?

If the intent of the rule is to deny use of prohibited functionality
why does it matter if a device or system that provides permitted
functionality is commercially available?

Andy

Wording is specifying commercially produced devices ie. Flarm and not
some homebuilt device
that someone my claim is equivalent.
Limit of functionality can be used to ensure , if this path is chosen,
that outside information is limited to that
which satisfies the anti collision objective, without providing
additional information that is useful tactically, such as
gaggles, climb rates, possibly energy paths that are not permitted
under the current rules philosophy.
What and how all this nay be done will be a long topic with many
opinions.

Ok, let's get specific. *I have ordered PowerFLARM. *I am also an
alpha and beta tester for, and user of, LK80000 tactical flight
computer software. *Do the proposed 2011 rules allow me to interface
PowerFLARM with LK8000 and to use any FLARM information presented by
LK8000 during SSA sanctioned contests?

Andy,

I also am on the PowerFLARM list and am testing LK8000. *It provides a lot of information!! (http://www.LK8000.it) *I have also noted that XCSoar version 6 has a nice PowerFLARM interface. *I don't own SeeYou Mobile; however, I believe it also has an interface.

Back to APRS, they are commercially available. *Maybe I should have said the off the shelf components are available. *(It is kind of like hooking up a Garmin 12xl to a EW Model D.) *The tall pole in the tent for many is the Amateur Radio license requirement.

I think 6.6.3 needs some work but maybe that won't happen for 2011.
6.6.3 relates to the prohibition of 2 way communications devices but
it also includes anti collision devices. These were probably included
in this section because FLARM is a 2 way device. However the ZAON MRX
is a passive receiver and not a two way communication device. It does
not belong in this section, or in the appendix that qualifies this
section.

There seems to be a case for moving anti-collision devices to a new
section and not including them under the prohibition of two way
communication devices. Maybe also need a separate section for
position reporting devices so that APRS can be either allowed or
prohibited. The section on APRS would need to address whether in air
reception of APRS reports is allowed.

The current rule appears to prohibit the carrying of a 2m amateur
band transceiver whether it is used for APRS or not.
