Default Changes to several IGC-approval documents


I'm afraid your communication below is causing some confusion. You say that "Diamonds level IGC-approval now applies to..." the LX Colibri 1. Since there are three levels per the latest Annex B to the sporting code and the verbiage around those levels has changed from an earlier version of Annex B, which one is "Diamonds level?"

In fact, the updated Approval Doc on the GFAC section of the FAI Website says the Colibri 1 is approved for " All IGC Badges and Distance Diplomas".

So which level is it: (which is what the approval document says) or (which is what "Diamonds level" seems to imply, thereby excluding Diplome flights).

Latest Annex B of Sporting Code IGC-approval for all flights. This applies to Flight Recorders that may be used for evidence for all flights up to and including FAI/IGC world records. For new types of recorders, compliance with the current Specification is required. For types with existing IGC-approvals to this level, "Grandfather Rights" ( below) apply unless there are major differences compared to the current Specification, as assessed by GFAC. IGC-approval for IGC/FAI badge and Diploma flights. This applies to Flight Recorders that may be used forevidence for all IGC/FAI badge and distance Diploma flights, but must not be used for the validation of IGC/FAI world record flights. For competition flights, see This level may be used for new recorders that do not meet the current Specification in some areas. For types of recorder that are already IGC-approved, this level may be used for those whose characteristics are now below the current Specification standard, particularly on security or accuracy of data, as assessed by GFAC. IGC-approval for badge flights up to Diamonds. This applies to Flight Recorders that may be used only for evidence for FAI/IGC Silver, Gold and Diamond badge flights, although for competition flights see This level may be used for recording systems that have significantly lower standards of security and other characteristics compared to those for higher levels of approval, as assessed by GFAC. No IGC-approval/non-IGC-approved Recorders. This applies to types of Flight Recorders that have either not been tested and approved by GFAC to IGC standards, or to recorders that were previously IGC-approved but where a major security or other problem has been shown to exist which could compromise the integrity of flight data. It also includes FRs used in other FAI Airsports that output in the basic IGC file format where such recorders have not been submitted for IGC-approval.

Preamble from lates Colibri approval doc:
Recorder Name: LX Navigation Colibri models 1 and 4(note that the Colibri II model of 2011 is a different design and has a separate IGC-approval document)
Levels of Approval: Colibri Model 4 and 4F: All Flights
Colibri Model 1 (see para 1.1.1 & 1.1.2): All IGC Badges and Distance Diplomas

On 1 October, several IGC-approval documents were revised.

This is the final phase of the Security review that was carried out in 2011, the results of which were approved by the IGC Bureau and IGC Plenary, for action on 1 October 2012.

Diamonds level IGC-approval now applies to the following:

Cambridge 10, 20, 25 (the "legacy" models)

Filser/LXN DX50, LX20 (with RSA192), LX21, LX5000 IGC,

LXN Colibri 1,

SDI/LXN Posigraph,

Zander GP940.

IGC-approval is withdrawn from the following types of FR due to security that is well below modern standards:

EW FR A-D with separate GPS receiver,

Filser/LXN LX20 batch 1 without RSA,

Print Technik GR 1000/1000A.

There are now 45 types of IGC-approved Flight Recorders from 17 different manufacturers.

IGC-approval documents are available on the FAI/IGC web page: http://www.fai.org/gnss-recording-de...ight-recorders

Scroll down to "IGC-Approved Flight Recorders - Approval Documents"

The click on the box underneath which says:

"IGC-approval Documents for all IGC-approved Flight Recorders".

This will call up a list of documents, the first one being "IGC-approval tables". This starts with a table of all IGC-approved FRs, and the current Approval document can be obtained by clicking the Date column on the right.. The FR table is followed by a table of manufacturers, then IGC-approval history and an article on the beginnings of the use of GPS in gliding.

This is followed by individual IGC-approval documents in alphabetical order of manufacturer’s name. Scroll down to your Recorder type and click on its name. The IGC-approval document will then download automatically to the directory that you have set for downloads.

In case of difficulties with the FAI/IGC web pages, the GFAC Chairman’s web site has duplicate information on Flight Recorders, see:


Click the first line "IGC-approvals for GNSS Flight Recorders summary ... ". On the first page is a table of all of the types of IGC-approved FRs. Find the type of recorder that you want in the table and click the date of the latest approval document at the right hand side of the table boxes. This should call up the IGC-approval document in PDF format.


IGC-approval follows test and evaluation by the IGC GNSS Flight Recorder Approval Committee (GFAC) in accordance with Annex B to the Sporting Code for gliding and the Technical Specification for IGC-approved GNSS Flight Recorders. The Technical Specification is available through the igc-approved-flight-recorders web site above and the Sporting Code for gliding through www.fai.org/igc-documents
