with a male 9-pin RS232 connector, and a female RS232 on the other end together with a small red light indica-
tor.
GPS receiver board. Garmin GPS25 parallel receiver capable of receiving data from up to 12 satellites for any
one fix.
Pressure altitude sensor. Intresema (Switzerland) MS 5534A, compensated for temperature variation. The FR
case is vented to atmosphere and records "cockpit static" pressure.
National regulations. These may apply to electrical and electronic equipment, such as the EC "CE" mark for
compliance with EC directives on EMC and voltages. Compliance with such regulations is not the responsibility
of FAI. This equipment has the EU CE mark.
FIRMWARE
Version 2.04 or later. This is shown in the header record of IGC-format flight files in the form "HF RFW Firmwa-
re Version: 2.04"
SOFTWARE
Program file functions. The short program file DATA-ZAN.EXE is for transferring flight data from the FR to a
PC and automatically produces a *.ZAN binary file and an *.IGC file for the last flight, leaving a menu on screen
for transfer of other flight data. The file CONV-ZAN.EXE is for conversion of a *.ZAN flight data file to the IGC
format, if the IGC file is not available, or as a later check of the IGC file. The file VALI-ZAN.EXE checks the
security and integrity of an *.IGC file, and ensures that data that is designed to be secure has not been altered
since it was transferred from the FR.
Versions to be used. For correct operation, Version 18 or later of the program files must be used. The initial
release date was 6 September 2001 for the V18 DATA and CONV programs, 11 October 2001 for the VALI
program. These program files are backward compatible with the earlier Zander GP940 recorder.
Free availability. The DATA, CONV, and VALI files are copyright of the FR manufacturer but are freeware. The
latest versions may be obtained from the IGC GNSS Internet site for software or through the IGC/GNSS site
through a link. See the site titles given at the beginning of this document.
CONDITIONS OF APPROVAL:
Permitted Connections. The position of the connectors is described above under Hardware.
1.1 External antenna to 9mm circular BNC bayonet connector.
1.2 Custom-wired 9-pin RS232 female connector to the15-pin male connector on the case. For power, Pilot
Event (PEV marker) button, also connection to a glider computer or display unit where available.
1.3 Male 9-pin RS232 connector to the15-pin female connector on the case, for transfer of flight data to and
from a PC.
1.4 Extra peripheral units such as displays have not been tested as part of this IGC-approval and are a matter
between the manufacturer and customers.
Security of the Equipment. GFAC is presently satisfied with the physical and electronic security of this equip-
ment. See para 4 on security seals.
Installation in a glider. The FR may be fitted anywhere in the glider, subject to para 3.2 on sealing and that in
Motor Gliders the position is suitable for recording Engine Noise Levels (ENL). If the GPS antenna is accessible
to the crew in flight, no attempt must be made to inject data; any abuse of this may lead to a future requirement
to place the antenna out of reach of the flight crew. Particularly in single-seat gliders, the position of any ancil-
lary displays connected to the recorder should not be remote from sight lines used for pilot lookout and scan for
other aircraft and gliders.
Motor gliders. A microphone and frequency filter and weighting system automatically produces an ENL (Engine
Noise Level) value with each fix. ENL figures vary between 000 and 999 in steps of 004. The system is de-
signed to emphasise any engine noise but at produce only low ENL values in normal quiet gliding flight. The FR
should be positioned in the glider so that it can receive a high level of engine and/or propellor noise when power
is being generated. GFAC has tested the FR in motor gliders with two-stroke and 4-stroke engines, but not with
Wankel or electric power sources. For details of typical ENL values, see para B.4.
Electric engines. If an electric engine is to be used, GFAC should be notified beforehand so that tests can be
carried out in order to establish ENL values.
