CS ACNS.D.ELS.030 Flight Deck Interface
(continued)
b)
Input which is not intended to be operated
in flight, is not readily accessible to the flight
crew.
The Transponders have a Ground Test mode, which
requires a unit power cycle while depressing a soft key.
CS ACNS.D.ELS.040 Integrity
The Mode S ELS airborne surveillance system
integrity is designed commensurate with a
“minor” failure condition.
Mode S operations are classified as a Minor failure
classification for the GTX 335/335R/345/345R units.
The transponder is designed to meet design assurance
level C which exceeds the “minor” failure classification
for Mode S ELS.
CS ACNS.D.ELS.045 Continuity
The Mode S ELS airborne surveillance system
continuity is designed to an allowable qualitative
probability of “remote.”
The GTX 335/335R/345/345R units have a design
assurance level of C “remote” for listed functions.
The GTX 335/335R/345/345R units also have a maximum
ELS system failure rate of no less than 5000 hours using
the MTBF rates, or 2.0E-04 failure rate.
CS ACNS.D.ELS.050 Dual/multiple
Transponder Installation
If more than one transponder is installed,
simultaneous operation of transponders is
prevented.
Dual transponder installations are configured by the
installer.
A compatible control device (e.g., GTN 6XX/7XX) or a
compatible external standby input discrete ensures that
only one transponder can be in a state other than
standby.
CS ACNS.D.ELS.055 ICAO 24-bit Aircraft
Address
The ICAO 24-bit aircraft address assigned by the
competent authority is correctly implemented on
each transponder.
The ICAO address is programmed as part of the
transponder configuration by the installer and verified as
part of the transponder configuration and return to
service procedures.
CS ACNS.D.ELS.060 Antenna Installation
a)
The installed antenna(s) has (have) a
resulting radiation pattern which is (are)
vertically polarized, omni-directional in the
horizontal plane, and has (have) sufficient
vertical beam width to ensure proper system
operation during normal aircraft maneuvers.
Transponder antenna must be compliant to
TSO 112( ), TSO C66( ) or C74( ).The installation manual
provides a list of compatible antennas.
b)
Antenna(s) is/are located such that the effect
on the far field radiation pattern(s) by the
aircraft structure are minimized.
The installation of the antennas is not covered by this
installation manual, however, guidance for the antenna
locations is provided in the installation manual.
