Update to IGC-approval for Zander/SDI 941 recorders

An update to the IGC-approval document for the Zander/SDI 941 recorder
has been agreed and is effective from 20 August 2006. The revised
document will appear on the web site shortly.

The reason for this update is that at the recent World Championships in
Sweden, under poor reception conditions some timing errors were found
in IGC files from type 941 recorders. The reason for these errors is
corrected in Firmware Version V2.11 and the upgrade to 2.11 is
available free to recorders sent to the manufacturers SDI and Zander.
For performances that require evidence of accurate time, where type
941recorders are concerned, only those with Firmware V2.11 or later
should now be used. These points are covered in the amended
IGC-approval document in which the rest of the wording is also updated
to that used in recent approvals.
