1.17 µA
10 µA centering
Desired track
Fly right when J1-33 is positive
with respect to J1-31
Full Scale - 5 nmi enroute
1 nmi terminal
0.3 nmi (user selectable)
Up to three 1000Ω loads
DESCRIPTION
Transistor current source
0 to +3.5 Vdc = Not Valid
+18.5 Vdc to +30 Vdc = Valid
200 mA current source
Analog voltage source referenced
to ground
0 to 150 mVdc = Not Valid
250 to 900 mVdc = Valid
Up to three 1000Ω loads
DESCRIPTION
Polarity reversing analog current
source referenced to ground
±40 mV
Next or TO waypoint
J1-34 is positive with respect
to J1-31 when the aircraft and
the last or FROM waypoint are
on the same side of a line
perpendicular to the desired track
and passing though the next or
TO waypoint. Polarity is reversed
for the FROM condition.
40 mV for each of up to three
200Ω loads in parallel
