OLC - Action Needed

The response from both SSA and OLC has been very positive.

Is there a reason why the OLC can't design its site so that you upload a
CAI file, and the site takes care of the rest?

Chip Garner and many others have worked to overcome
the technical difficulties and have generated and tried
to publicize effective workarounds and patches. Yesterday's
daily scores from USA show a few red marks [but a huge
number of greyed-out flights], suggesting that the
word is getting out but still has some way to go.
OLC have said that they are considering re-instating
wrongly-rejected flights -

I don't understand why haven't they done this already. Otherwise, the
OLC measures two things -- your soaring ability, and your computer
ability. Why is your computer ability relevant?

please look at

for the full explanation of what has been happening.

I hope this helps.

OLC is working on rescoring all the Cambridge logs to get rid of the
red marks. Temporarily they all have yellow marks while they are
working on the program. Please be patient....

To avoid any misunderstanding, let me clarify. I made
a cursory check through the February and March 2006
German daily scores [weekends only] and noticed no
or very few red marks. This suggested to me that the
problem was not common in Germany, but there could
be a number of reasons for that. Later, I checked

There is a very obvious reason why the Cambridge-Problem doesnt really exist in
Germany: we dont usually USE Cambridge Loggers here.
At least i know of no Cambridge loggers anywhere nearby. :-)

This is a bit of a success story.

After trying no less than six different USB 2.0 to Serial adaptors trying to
download a flight from a Volkslogger with SeeYou, StrePla and DOS, I finally
bought a $75 high-speed serial PCIe card. Using this card, SeeYou
downloaded a secure file from the Volkslogger in about 20 seconds. OLC
accepted the file from SeeYou just as quickly - no red mark.

The USB adaptors seemed to work and would download a non-secure file but the
secure file was always corrupted. USB 2 adaptors may be the source of some
of the problems.

I uploaded a file from a fairly new Cambridge 302, using SeeYou (3.4)
as always, and for the first time, it's red marked. Tried removing the
claim and uploading manually, no change. Don't see any with yellow
marks.

Will try the SeeYou patch tonight. Does anyone know of any free 3d
party software that does OLC claims like SeeYou? Naviter has a
ConnectMe program that's free. What they need is a SubmitMe program for
OLC!

I have always downloaded from my 302 to an Ipaq using the Cambridge
software. At the end of the download, it will tell you whether the file
passes the security test. Does SeeYou do the same? If not, download
the VALI-CAM2 file from http://www.cambridge-aero.com/300series.htm, and
see if the IGC file passes the security test. If not, download the IGC
file again from the 302. If the file still doesn't pass, contact Cambridge.


Will try the SeeYou patch tonight.

I don't think it will work with the 302, as it is designed to solve a
problem that the 302 doesn't have.

Thanks Greg. The ValiCam2 program reports:

F:\i:Valicam2.exe 649C40R1.IGC
ValiCam for the 302 Version 1.0.0

Checking File:649C40R1.IGC ...

Log Data Integrity OK
Signature Data Integrity OK
Security Fail

....

I wonder what would cause a 302's log file to fail? Could this have
been different if I'd used Cambridge's utility to download it instead
of ConnectMe?

Some versions of SeeYou have known problems with corrupting IGC files
when downloading from secure flight recorders. Make sure you have the
latest version of SeeYou, and if you to be absolutely certain of getting
a valid IGC file, use the short DOS program from the IGC web site...

So how come OLC is rejecting my Volkslogger files? No Cambridges in my
cockpit.

Question: What type of download are you using? The Garrecht
Volkslogger is a late 1990s design when processor speed and memory size
were not as easy to obtain cheaply as they are today. Therefore
Garrecht proposed two types of data download, a rapid one that had
little or no security encoding and a slower one that has IGC-standard
public/private key encoding embedded in the downloaded IGC file. The
IGC GFA Committee rather reluctantly accepted this, mainly to make it
quicker to deal with downloading in large gliding competitions. The
IGC-approval document for the Volkslogger says:

2.4. Data Transfer from the FR to a PC
The DATA-GCS.EXE file menu provides two modes of transfer, a "Test"
mode and a "High Security" mode. Only the High Security mode
provides the electronic security signature which is required for
validation of FAI/IGC record and badge flights. Data transferred by the
"Test" mode will not be accepted for such flights, and it will not
pass the VALI check (para 5), although competition organizers may allow
it for competition flights where rapid data transfer rather than
security is a priority in well-supervised centralized competitions.

--------- end of extract ----------

Two points:

(1) With the increased availability of cheap rapid processors (as
spin-off from the games industry), non-IGC security is no longer
allowed in an IGC-approved recorder. The Garrecht system above is
therefore a one-off, reflecting the conditions in April 1998 when the
IGC-approval was originally issued.

(2) Not being part of the OLC organisation, I do not know whether they
ask for Volkslogger flights to have the IGC security standard or not.
However, without it the free VALI-GCS.exe validation program will
reject the flight data file concerned.

Ian Strachan
Chairman IGC GFA Committee

Thanks for the comments, Ian. I am aware of the two modes and use the
fast unsecure method for casual flights. I have been using ConnectMe
to download secure logs from my Volkslogger since participating in the
OLC and have previously had no problems. In this case, there does
appear to be a problem with my file and maybe the issue is not the OLC.

It is frustrating, though, having made a great flight and having to
spend longer downloading and fixing the log than the flight time!
Clearly the security issues are causing more problems than they were
designed to prevent. Like many other glider pilots, I wonder how many
bogus logs there are and even if it would be possible to get away with
one, given so many people watching the forum?
