5.2.8.1.4 Flag
5.2.8.1.5 OBS
VOR OBS ROTOR C and H are a buffered 400 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.
5.2.8.1.6 VOR/LOC COMPOSITE
With a standard VOR test signal applied, VOR/LOC COMPOSITE OUT is 0.5 ± 0.1 Vrms into a 10 k
load. With a standard Localizer centering test signal applied, VOR/LOC COMPOSITE OUT is 0.350
±0.05 Vrms into a 10 k load.
5.2.8.1.7 GLIDESLOPE COMPOSITE
With a standard glideslope test signal applied, GLIDESLOPE COMPOSITE OUT is 0.350 +
0.05 Vrms
into a 10 k load.
5.2.8.1.8 NAV ILS ENERGIZE
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 A.
