1.5 Installation Approval

The conditions and tests required for TSO approval of this article are minimum
performance standards. Those installing this article either on or within a specific
type or class of aircraft must determine that the aircraft installation conditions are
within the TSO standards which include any accepted integrated non-TSO
functions standards. TSO articles and any accepted integrated non-TSO
function(s) must have separate approval for installation in an aircraft. The article
may be installed only according to 14 CFR Part 43 or the applicable airworthiness
requirements.

1.6 TSO Failure Condition Classification

The KT 74 Mode S Transponder has been designed to the major failure condition
classification as described by TSO C112d and C166b. Malfunction of the functions
defined in Paragraph 3.a of these TSOs are a major failure condition.
1.7 Non–TSO Functions
The KT 74 Mode S Transponder contains the following non-TSO functions:

Stopwatch and Flight Timer: The transponder provides a simple stopwatch
and flight timer function, displayed on the front panel.

Altitude Monitor: The Altitude Monitor activates an audio annunciator or
annunciator light (depending on installation) when the aircraft pressure altitude
differs from the previously selected altitude by more than 200 feet.

Altitude Repeater: This is a serial altitude output that can connect to a GPS or
other device needing serial altitude data – this allows the transponder to act as
a repeater for the altitude input instead of requiring a second altitude encoder.
The operation of each of these functions is described later in this manual.
The non-TSO functions defined in this section are not part of the TSO approval.
The non-TSO function data included in this section is approved under 14 CFR
21.305(d).
