System and Type Approval Information
The Dual VHF/AM Airband Transceivers
FSG 90F(X)
comply for both, the combined
8.33 kHz/25 kHz as well as "25 kHz only" channel spacing with all applicable National
and International Type Approval requirements, for any airborne and ground operations.
2.5.1
JTSO Authorization LBA.O.10.911/98 JTSO (LBA Luftfahrt-Bundesamt) based on
*EUROCAE ED-23B Airborne requirement is met besides 8.33 kHz requirements also
for the 25 kHz ONLY channel spacing.
This also includes Immunity according to ICAO ANNEX 10 against FM Broadcast
Interference.
This also includes fulfillment of specific audio filtering required in areas with CLIMAX
operation in 25 kHz channel spacing.
* Associated EUROCAE ED-14C / RTCA DO-160C Environmental requirements.
* Associated EUROCAE ED-12B Software requirements based on ED-23B.
2.5.2
Reg TP No. A132937J, stringent German Type Approval requirements Reg TP
321 ZV 034 (airborne) and Reg TP 321 ZV 039 (ground).
2.5.3
DFS (Deutsche Flugsicherung) No. B-7850/97 (ground) German Type Approval
requirements.
2.5.4 BZT No. B132705J, CE Conformity,
* Associated with DIN/ISO 7637-1 DC supply in 12 V vehicle.
IMPORTANT!
•
For the first time after one year, then every 2
nd
year, ground
applications using 8.33 kHz channel spacing require checking of
the high precision reference frequency (tolerance less than
± 1.5 ppm) and recalibration, if necessary!
•
Every 4
th
year, airborne applications using 8.33 kHz channel
spacing require checking of the high precision reference frequency
(tolerance less than ± 5 ppm) and recalibration, if necessary!
•
All applications in the 25 kHz channel spacing require no
recalibration (frequency accuracy tolerance less than ± 20 ppm).
•
All tolerances include the full operating temperature range of
-20°C ... +55°C / -4°F ... +131°F.
•
Checking and recalibration must be performed by the equipment
manufacturer or through authorized and approved avionics
services. This requires use of specified test equipment as well as
applicable test procedures (software) released by the manufacturer.
