Hi John,
I don't speak for either the OLC or the GFA, but as an innocent
bystander I can make a couple of comments.
The OLC is a private organisation which makes its own decisions. It is
not directly connected with the FAI or IGC and the GFA has no more
influence with it than any other customer would have. We are also quite
a small customer in the whole scheme of things.
The older Cambridge flight recorders are susceptible to hacking because
while their security was adequate with the computing power that was
available to individuals in the 1990's, it is no longer adequate given
what is available now. The IGC has also downgraded these devices and
will almost certainly withdraw their accreditation soon.
The OLC has a particular security problem because flights are submitted
online and the only security for the system is the quality of security
available in the device itself. There are no Official Observers or
competition scorers to confirm the flight.
The OLC has seen examples of attempted cheating and I guess they think
it is in their interest to maximise the integrity of their competition
even at the expense of some short-term disappointment for a small and
reducing number of customers. It is certainly not a sudden decision, it
has been coming for a while. All flight recorders have a use-by date
and it is a tribute to Cambridge that theirs have lasted as long as they
have. This is not the first device thay have removed, and it won't be
the last.
My advice is to upgrade your flight recorders. I think it is highly
unlikely that this decision will be changed.
Depending on which part of OLC you are entering, Flarm traces are
acceptable, though not for motor gliders of course.
Cheers
/Tim/

Brought to my attention today that from January, the OLC will not
accept traces from Cambridge Model 10/20/25 loggers. This will cause
us problems as all club gliders are equipped with these loggers. Don't
know if the GFA is aware or has had any input, but would suspect it we
are not the only ones affected .... so maybe if we all make enough
noise we might be able to get the OLC people to reconsider this sudden
decision which will take effect mid way through our season and which
has not really given anyone much opportunity to consider other
arrangements. The announcement :
The OLC's support to GPS-Nav/Cambridge 10/20/25 will cease on Dezember
31st
The validation procedure of GPS-Nav/Cambridge 10/20/25 is out of date
since a long time and administring it further is not sustainable. In
efforts to find a solution with representatives from the manufacturer
we could not come to a feasible conclusion. Therefore participation at
the OLC with GPS-Nav/Cambridge 10/20/25 will be only possible until
the end of 2011.
We appologize for any inconvenience and hope for your understanding ...
