Annex:
FAI approval for GPS flight recorder ZANDER / SDI GP941
The most important points are:
Required firmware version (program inside of flight recorder): version 2.04 or later
The version is shown when reading flights from flight recorder with PC; older versions must be upgra-
ded by manufacturer for FAI approved flight validation.
Required hardware version: version 2 or later
The hardware version is the number left of decimal point of firmware version number; all GP941 pro-
duced until now have the hardware version number 2.
PC software:
(DOS programs)
DATA-ZAN.EXE
version 18
dated Sept. 6, 2001
(to read flight data from flight recor-
der)
VALI-ZAN.EXE
version 18
dated Oct. 11, 2001
(to validate flight data files)
CONV-ZAN.EXE
version 18
dated Sept. 5, 2001
(to convert ZAN files to IGC files)
For FAI flight validation these versions or later versions of these programs must be used. Older ver-
sions of these programs must not be used for FAI purposes. So IGC files produced by the old Win-
dows program WINGP.EXE cannot be used for FAI flight validation. Instead, ZAN files produced by
WinGP must be converted to IGC format using the latest version of DOS program CONV-ZAN.EXE.
When the new version WINGP940.EXE is ready, this new Windows program may be used instead of
the DOS program.
Note: the DOS programs listed above are also valid for the old ZANDER GP940 flight recorder; so
these programs replace the old DOS programs made for GP940.
The latest version of these DOS programs are available from IGC GNSS homepage.
Reading flights: in presense of an official observer
For FAI validation both ZAN and IGC files are necessary; one diskete with both files will be kept by
the official observer, one diskette is for the pilot.
Position of GP941 within glider and type of fixture to glider: no requirements
The official observer has to check which type of recorder and which serial number is in the cockpit
during takeoff.
Monitoring engine run in glider: by microphone
A test run of engine at the beginning or the end of the flight is not necessary for FAI purposes
Pressure altitude calibration: at this time every two years at the manufacturer or other institutions
accepted by the national aero club. Maximum calibration altitude: 10 000 m.
Maximum flying altitude for FAI flight validation: 10 000 m
