Hi Pam,
The current thread is focused on the software upgrade for the
FLARM-IGC device. In the Flarm website software download section it
refers to "all devices". Can you please confirm whether the v5.08
upgrade is applicable/necessary for Oz-Flarm units.
Regards,
Geoff V

FLARM-IGC flight recorders - security update and revised IGC-approval
A significant update to the GPS Flight Recorder function of FLARM-IGC
units is now available. Owners are advised to incorporate this as soon
as possible. It is available through a web download, see below.
FLARM-IGC owners may recall that in 2012, software appeared on the web
from an unknown source that enabled false Flarm-IGC files to be produced
that passed the IGC electronic validation check. To counter this, a
security update to Firmware Version 5.8 is now available via:
www.flarm.com/support/updates/index_en.html
and click on "flarm_508fw" on the right hand side of the page to
download this file. This file will update a FLARM-IGC unit to Firmware
5.08 standard using the standard FLARM update procedure (via a micro-SD
card or a PC-based update). Note that an update to the Flarmtool
utilities program incorporating V5.08 is also available by clicking
"Installation V5.08" on the right hand side of the same web page.
** Important Note ** Owners should note that the IGC-approval for
earlier versions of Firmware (from V4.0 to V5.6) will be withdrawn on 30
April 2013. This is to ensure that the possibility of false IGC files
being produced using the malicious software referred to above, is
eliminated.
A revised IGC-approval document is available on the IGC and GFAC web
pages:
www.ukiws.demon.co.uk/GFAC/approvals/flarm-igc.pdf
or
www.fai.org/gnss-recording-devices/igc-approved-flight-recorders
For electronic validation of IGC files produced with V5.8 firmware, use
either the latest Flarmtool program (see above) or the free IGC Shell
program together with the latest Flarm DLL file which is named
IGC-FLA2.DLL to differentiate it from the earlier file IGC-FLA.DLL.
For the IGC Shell program and DLL files, including the new IGC-FLA2.DLL,
see:
www.ukiws.demon.co.uk/GFAC/downloads.htm
or
www.fai.org/gnss-recording-devices/free-software
The above may seem complex, but Flarm owners are used to making regular
updates that in the past have been to optimise the Flarm Traffic
Avoidance and warning system. The difference with this update is that
it increases the electronic security both of the Flight Recorder
facility and of future downloaded IGC files.
In view of the important of this security update, please give this
announcement publicity so that current owners and users of FLARM-IGC
units are aware of it, and its implications. The Flarm company are
doing likewise through their normal channels of communication to Flarm
owners, gliding software producers and OLC organisers.
