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.
