The Flag output is capable of driving up to three 1000 Ω meter loads. When valid information is present
(Flag OUT OF VIEW) the Flag output is 375 ±80 mV
DC.
When invalid information is present (Flag IN
VIEW) the Flag output is 0 ±25 mV
DC.
4.8.2.5 OBS
Pin Name Connector Pin I/O
VOR OBS ROTOR C P4006 9 Out
VOR OBS ROTOR H (GROUND) P4006 10 Out
VOR OBS STATOR D P4006 13 In
VOR OBS STATOR F P4006 12 In
VOR OBS STATOR E/G (VOR/LOC
COMMON)
P4006 11 Out
VOR OBS ROTOR C and H are a buffered 500 Hz output that is intended to drive the OBS rotors. VOR
OBS STATOR D and VOR OBS STATOR F are each phase and amplitude shifted version of the VOR
ROTOR C output. Each pair is intended to read one of the two windings of the indicator’s OBS stator.

VOR/LOC COMPOSITE OUT P4006 8 Out
With a Standard VOR Test Signal applied, VOR/LOC COMPOSITE OUT is 0.5 ±0.1 V
RMS
into a 10 kΩ
load. With a Standard Localizer Centering Test Signal applied, VOR/LOC COMPOSITE OUT is 0.350
±0.05 V
RMS
into a 10 kΩ load.
4.8.2.7 ILS ENERGIZE
Pin Name Connector Pin I/O
ILS ENERGIZE P4006 29 Out
The driver output voltage is not more than 1.0 V when sinking 20 mA. The maximum off state leakage
current with respect to GND is less than 10 µA.
