I suggest you seriously research the history of what happened in 1995
to 1997. The IGC had rules in place for loggers which GFAC blatently
defied when it came to approval. The rules were then changed quite
outside the system you talk about.

I do not wish to get into further argument with Mike Borgelt but I must
point out that the interpretation above is his own. It is certainly not
mine or that of GFAC or IGC since they oversee GFAC and review the GFAC
annual report to IGC at each plenary.

He refers, I think, to the process that resulted in the "IGC Badges up
to and including Diamonds" level that was applied to the EW series of
recorders that do not have their own GPS but must be connected by cable
to one of the Garmin range of GPS receivers. And would have probably
applied to the Borgelt Joey recorder had he submitted an IGC version for
IGC-approval.

Mike, I do not want to get involved in a slanging match or indeed to
reply further. But for those who are new to this, I really had to
comment on your statement above in case people thought that it was the
only interpretation of early events in the IGC-approval process. I do
not doubt that it is yours, but it may not be other's.

The dates of all IGC-approvals including historic ones is on the
gliding/gnss web site and the history up to the issue of the EW
IGC-approval is:

16 Jan 96 - Cambridge Models 10, 20 and 22, initial issue

31 May 96 - Peschges VP8, initial issue

12 Aug 96 - Filser LX20, initial issue

10 Nov 96 - Zander GP940, initial issue

20 Mar 97 - Print Technik GR1000, initial issue

25 Mar 97 - Filser LX20 Version 2 Approval, with the addition of motor
glider engine recording

19 Apr 97 - EW "EWFR A & B" for badge flights up to and including
Diamonds, when connected by cable to one of a list of approved GPS
units, listed in the IGC-approval document.
