Have all world records that were set with these devices been retrospectively
cancelled??

If not, why not if the security flaw is enough to cause the revoking of the
approval?

Hi,

I understand that "old" technology must be made obsolete at some point,
but I think this is premature. The GPS-NAV is a very reliable and secure
system. It is a shame to make the units less valuable to thousands of
owners. I must respectfully disagree with the decision of the IGC.
There... I've said my piece.

Good Soaring,

Paul Remde

IGC FLIGHT RECORDER APPROVAL LEVELS

A decision was made on 5 March by the IGC Plenary meeting in Lausanne,
Switzerland, that will affect the Cambridge models 10, 20 & 25, Print
Technik GR1000 series and the Zander 940 types of GPS Flight Recorder.
The annual Plenary meeting is the highest decision-taking body within the
IGC structure. This was the final stage in the process of reviewing
World Record (WR) procedures that was carried out by a working group led
by the IGC Bureau during 2004.

A discussion was held on electronic security systems for flight recorders
that may be used for WR flight evidence. It was decided by a two thirds
majority vote that flight recorders not having public/private key systems
such as RSA or equivalent as part of the system by which manufacturer's
Validation program files are available through the IGC GNSS web pages,
will not be permitted for WR evidence. In accordance with Annex B of the
Sporting Code for Gliding (SC3B), para 1.1.4.2, this will take effect on
15 March 2006 and over-rides any "Grandfather Rights" for the recorders
concerned.

The manufacturers have already been notified and the period of a year
allows them to consider the possibility of an upgrade for these recorder
models.

Otherwise, the new IGC-approval level for these recorder models will be
at the "all IGC/FAI badge and diplomas" level (SC3B para 1.1.3.3.2) with
effect from 15 March 2006.

Finally, please note that this decision does not affect the use of such
recorders in gliding competitions (SC3B para 1.1.3.3.6 refers).
