3 TERMINAL LEARNING OBJECTIVE: ACTION TEXT: Identify the major
components, features, functions, and operational characteristics of
the Horizontal Situation Indicator (HSI)(KI-525A). CONDITION: In a
Classroom, given visual representations of the HSI (KI-525A)
components and applicable references. STANDARD: Answer questions
pertaining to the major components, features, functions and
operational characteristics of the Horizontal Situation Indicator
(HSI) (KI-525A).

7 Aeronautical Information Manual Explanation of Changes
(Change 1) Effective: 26 Jul 12 This change explains why slaved
compass systems may be susceptible to heading errors on the ground
and alerts pilots to the fact that the systems erroneous heading
may not self-correct. It also offers mitigation strategies to avoid
a possible heading misalignment at takeoff. Para 117 d
Slide 8
8 d. Aircraft equipped with slaved compass systems may be
susceptible to heading errors caused by exposure to magnetic field
disturbances (flux fields) found in materials that are commonly
located on the surface or buried under taxiways and ramps. These
materials generate a magnetic flux field that can be sensed by the
aircrafts compass system flux detector or gate, which can cause the
aircrafts system to align with the materials magnetic field rather
than the earths natural magnetic field. The systems erroneous
heading may not self-correct. Prior to take off pilots should be
aware that a heading misalignment may have occurred during taxi.
Pilots are encouraged to follow the manufacturers or other
appropriate procedures to correct possible heading misalignment
before take off is commenced.

As of: Oct 2013 6 IFR TH-67s are equipped with the KI-825.
Installations are being completed when aircraft are in phased
maintenance. (This is NOT progressing quickly as from Jan 2013 Oct
2013 only one KI-825 was installed) Simulators will be updated when
50% of our fleet has KI- 825s installed. (Circa year 2033) Our
