ROLL STEERING LO This is an output. It is always grounded
FCS LOC ENG
: OPEN = Inactive
LOW = Active (Output can sink up to 250 mA)
LATERAL DEV FLAG +:
LATERAL DEV FLAG -:
Valid: 350 to 900 mV (high)
Flag in view:
≤ 50mV (low)
Output is capable of driving five 1k ohm parallel
loads.
VERTICAL DEV FLAG +:
VERTICAL DEV FLAG -:
Reserved for future use.
LATERAL SUPERFLAG:
Valid =
≥ 18 V in 28 VDC installations; ≥ 10 V in
14 VDC installations. Invalid =
≤ 3.5 V in all
installations while sinking 1 mA. Output can
source at least 250 mA.
VERTICAL SUPERFLAG: Reserved for future use.
LATERAL DEV +L:
LATERAL DEV +R-:
These outputs are differential pairs (+L and
+UP are positive). Output range is
± 300 mV
and is capable of driving five 1k ohm parallel
loads.
VERTICAL DEV +UP:
VERTICAL DEV +DOWN:
Reserved for future use.
OBS OUT: Used to excite the OBS resolver rotor. Nominal
output frequency = 450 Hz. Nominal unloaded
peak amplitude = 6 V. Output drive capability =
40 mA.
+TO / +FROM Flag Outputs:
To Indication:
From Indication:
+100 to +900 mV on +TO with respect to
+FROM when desired course is within
± 85° of
the bearing to the active waypoint.
-100 to -900 mV on +TO with respect to
+FROM when desired course is within 180
± 85° with respect to the bearing of the active
waypoint. Outputs are capable of driving up to
five 200 ohm parallel loads.
ALTITUDE ALERT ANNUNCIATE: HIGH = Inactive
LOW = Active (can sink up to 250 mA)
ALT ALERT AUDIO
: This output is active whenever ALTITUDE
ALERT ANNUNCIATE is active, Signal is 1Khz,
3.5 Vrms max into 500 ohms. Refer to
Paragraph 2.4.4.9 for the procedure to adjust
the volume.
