4.7 VOR/ILS Indicator
4.7.1 VOR/ILS Indicator Function
The VOR/ILS indicator displays both lateral and vertical, To/From indications, lateral flags, vertical flags,
and superflags.
VOR/LOC COMPOSITE OUT is a standard VOR/localizer composite signal which may be used to drive
the Left/Right, TO/FROM, and Flag indications of certain navigational indicators that contain an internal
converter.
GLIDESLOPE COMPOSITE OUT (011-01105-2X/-3X/-4X ONLY) is a standard glideslope composite
signal which may be used to drive UP/DOWN and Flag indications of certain navigational indicators that
contain an internal converter.
The ILS ENERGIZE* output goes low when the VLOC frequency is channeled to a localizer channel.
4.7.2 VOR/ILS Indicator Electrical Characteristics
4.7.2.1 Superflags
The output supplies not less than 500 mA on a 28 volt system with the output voltage not less than
(AIRCRAFT POWER – 1.5 V
DC) when the flag is to be OUT OF VIEW. The output voltage with respect
to ground is less than 0.25 V
DC when the flag is to be IN VIEW.
4.7.2.2 Deviation
The deviation outputs are each capable of driving up to three 1000 Ω meter loads with ±150 mVDC ±10%
with respect to 2.5V Common for full-scale deflection. The drive circuit provides for more than full-scale
deflection with a maximum course deviation output voltage of ±300 mVDC ±10%.
