KTX2
Installation Manual
1.3 TERMINOLOGY
Except where specifically noted, references made to “the Unit” or “the Installation” will apply to
the KTX2. Likewise, the terms “1090 Transponder”, “Mode-S Transponder”, or “Transponder”
will also mean the KTX2. References to “metal aircraft” will refer to aircraft with an aluminum
skin. “Nonmetallic aircraft” will refer all other aircraft including composite, wood, or tube and
fabric construction.
1.4 SCOPE
This Installation Manual applies to the modification of an aircraft under AML STC SA02525AK
for the installation of the equipment described in Table
1
-
1
. Interfaces between the equipment
listed in the second column and the KTX2 are covered by this STC. This STC is only applicable
to the 14 CFR, Part 23, Class I, II and III aircraft, as defined in Advisory Circular (AC)
23.1309-l E, which are identified in the AML. Installations in 14 CFR, Part 23 Class IV, Part
25, Part 27 and Part 29 aircraft are not authorized under this A ML STC.

1.4.1 Approved Aircraft With Systems Not Covered by the AML STC
Aircraft on the AML have been determined to meet the minimum required configuration for
application of the STC. However, since some of these aircraft may have been modified since
they were manufactured under their original Type Certification, it may be difficult to use the data
herein to completely confirm that the installation is in compliance with the STC.
It is therefore the Installer’s responsibility to make the final determination of STC applicability for
each individual aircraft.
Use this manual to evaluate each installation prior to modifying a Type Certificated aircraft to
ensure applicability and compliance with AML STC SA02525AK. If in doubt, the Installer should
consider requesting Field Approval or a unique STC to perform the installation. Consult AC 43-
210 for guidance on the Field Approval process. Antennas, particularly when installed on
composite and pressurized aircraft, will normally require separate approval.
1.5 INTRODUCTION
This section includes descriptions, specifications, TSO information, and installation approval
and limitations for the KTX2. The KTX2 system (also referred to as the Transponder) includes a
KTX2 device, an interface to an approved GPS receiver and connections to recommended
antennas, the pitot-static system and a power source.
The system requires additional 3
rd
party components. A list of system components is provided in
Table 1-2. See Figure 1-1 for an overview of the unit’s system interface.
Included in SECTION 2, paragraph 2.5 is a list of compatible equipment and equipment required
but not supplied with the system.
