GENERAL INFORMATION
This section contains general suggestions and information to consider before installation of the KTR 2280A.
Close adherence to these suggestions will assure optimum performance from the equipment.
NOTE:
The conditions and test required for the TSO/ETSO approval of this article are minimum performance
standards. Those installing this article, on or within a specific type or class of aircraft, are responsible
for determining that the aircraft installation conditions are suitable for the TSO/ETSO article. TSO/
ETSO articles must have separate approval for installation in an aircraft. The article can be installed
only if performed under article 14 CFR part 43 or the applicable airworthiness requirements.
NOTE:
Per AC 23.1309-1E, the probability of total loss of navigation and communication (a Hazardous
failure) must be less than 1E-7 (Part 23 Class III or Class IV) per flight hour and only dual installation
of KTR 2280A can support this probability requirement without the installation of additional navigation
or communication equipment. Additionally, other installation considerations must be analyzed (e.g.
electrical wiring and interconnect, power distribution, RF cabling and antennas) to determine the
acceptability.
2.2
UNPACKING and INSPECTING EQUIPMENT
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for evidence of
damage during shipment. If a claim for damage is to be made, save the shipping container to substantiate the
claim. The claim must be promptly filed with the transportation company. It would be advisable to retain the
container and packing material after all equipment has been removed, in the event that equipment storage or
reshipment must become necessary.

EQUIPMENT INSTALLATION
2.3.1
Avionics Cooling Requirements
The unit is cooled by a fan internal to the unit and an external fan attached to the rear rack assembly plate, the
latter being a part of the installation (Refer to Figure 2-21 KTR 2280A Installation Drawing). During installation,
do not block any holes in the unit cover(s) which would restrict air flow.
2.3.2
Equipment Location
The following paragraphs contain information pertaining to the initial installation of the KTR 2280A MMDR,
including instructions concerning the location and mounting of the supporting antenna(s).
The equipment must be installed in the aircraft in a manner consistent with acceptable workmanship and
engineering practices and in accordance with the instructions set forth in this publication. To ensure that the
system has been properly and safely installed in the aircraft, the installer make a thorough visual inspection and
conduct an overall operational check of the system on the ground prior to flight.
