Appendix I
Para 30.5.7.2
(cont)
.
True Heading - The CAU shall supply a CX output
g.
*
(phase C excitation) of true heading to the CIG.
The output source shall be a CX equivalent to a
26V-11-TX4C. The maximum rate of change of the
output shall be 200 deg/sec. The accuracy shall
*
be 4 arcminutes (10) plus 0.3 arcminutes/deg/sec
not including stable element position errors.
Heading Error - The CAU shall supply a clutched
h.
CX output (phase A excitation) of heading error
to the AFCS. The output source shall be a CX
equivalent to a 26V-08CX4C. The maximum rate
of change of the output shall be 200 deg\sec.
The range shall be -30 3 degrees to +30 3
.
degrees. The centering error shall be 8. arc-
minutes maximum and the engage error shall be
*
28 arcminutes maximum.
Pitch No. 1 - The CAU shall supply a CX output
i.
(Phase A excitation) of pitch angle to the AFCS.
The output source shall be a CX equivalent to a
26V-08CX4C. The maximum rate of change of the
output shall be 60 deg/sec. The range shall be
*
90 degrees. The accuracy shall be 5 arcminutes
(lo) plus 0.1 arcminutes/deg/see, not including
stable element position errors.
Pitch No. 2 - The CAU shall supply a CX output
j.
excitation) of pitch angle to
(phase C
the RAI. The characteristics of this output
*
shall otherwise be identical to pitch no. 1
(refer to 30.5.7.2i).
Pitch No. 3 - This CAU output to the RAI shall
k.
be identical to pitch no. 2 (refer to 30.5.7.2j). *
Roll No. 1 - The CAU shall supply a CX output
m.
(phase A excitation) of roll angle to the AFCS.
The output source shall be a CX equivalent to a
26V-08CS4C. The maximum rate of change of the
.
output shall be 300 deg\sec. The range shall
*
be O to 360 degrees. The accuracy shall be
*
5 arcminutes (10) plus 0.1 arcminutes/deg/see,
not including stable element position errors.
