    SECTION IV

    THEORY OF OPERATION

    4.1 GENERAL

    This section contains theory of operation for the KI 202, KI 206, KI 207 VOR/LOCGlideslope Indicator.

    4.2 THEORY OF OPERATION KI 202, KI 206, KI 207

    4.2.1 VOR/LOC Operation (KI 202, KI 206, KI 207)

    The KI 202, KI 206, KI 207 receive DC signals from a remote mounted VOR/LOC suchas the Bendix/King KN 77, or panel mounted KX 155 (via KN 72), KX 155A (viaKN 72), KX 165, or KX 165A. These DC signals (either current or voltage) are con-nected directly to the course deviation meter, To-From indicator and VOR/LOC warn-ing flag.

    4.2.2 Glideslope Presentation (KI 206, KI 207)

    The KI 206, KI 207(except -25) receive DC signals from a remote mounted glideslopereceiver/ converter such as the Bendix/King KNR 634A, or panel mounted KX 155,KX 155A, KX 165, or KX 165A. These DC signals (either current or voltage) are con-nected directly to the glideslope deviation meter and glideslope warning flag.

    4.2.3 VOR Course Resolver

    A standard ARINC six wire course resolver is included on the KI 202, KI 206. TheKI 207 contains no resolver or azimuth card. By turning the OBS knob, the azimuthcard and rotor of the course resolver are also turned. As the rotor of the resolver ro-tates about the stator windings, the coupling from the rotor to each of the stators var-ies. In normal VOR operation, a 30 Hz signal is connected to the rotor winding of theresolver as in Figure 4-1.

    For each position of the rotor shaft, the amplitude of the voltages on the Stator 1 andStator 2 windings is defined as in Figure 4-1. The angle is the angle of shaft rotationand is defined to be zero with an OBS (selected course) of 300 degrees and equal to

    90 degrees with an OBS of 210 degrees. Phase shift between the 30 Hz input to the2000 ohm resistor and either stator winding when at maximum coupling is 83 degrees.

    4.2.4 Course Datum Synchro

    (A course datum synchro is optional on the KI 202 P/N 066-3034-08 and the KI 206PN 066-3034-05.) Heading information is fed from a synchro transmitter located withinthe slaved directional gyro system to the course datum sync

    ure 4-2.

    hro B102 as shown in Fig-

    FIGURE 4-2 Course Datum Synchro

    A synchro control transformer (often referred to as a C.T.) does not have AC powersupplied to its rotor, but the rotor is designed to supply control voltages which reach anull (zero volts) when the control transformer rotor is in effective (actually 90 degreesdisplaced) alignment with the transmitter rotor. Upon moving the transmitter rotor soas to disturb this alignment, the voltage appearing across the rotor of the control trans-former varies as the sine of the angle of displacement The control voltages shown in

    All flags, pointers, and indicators shall not contact any other flags, meters, indicators,the warning flag housing, or the azimuth card when moved throughout their range ofmovement.

    5.3.1.4 Meter Deflection Range

    When viewed from a Standard Viewing Angle (15 above horizontal) minimum deflec-tion range for the VOR/LOC and glideslope (if provided) pointers shall be 0.630 incheseither side of the centered meter position (each reference mark on the warning flaghousing corresponds to 0.125 inches of deflection).
