A.3.13 VOR/ILS Indicator
A.3.14 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.
The ILS ENERGIZE output goes low when the VLOC frequency is channeled to a localizer channel.

The output supplies not less than 500 mA on a 28 volt system with the output voltage not less than
(AIRCRAFT POWER – 1.5 VDC) when the flag is to be OUT OF VIEW. The output voltage with
respect to ground is less than 0.25 VDC when the flag is to be IN VIEW.

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

+225 ±75 mVDC
.
When indicating FROM, output is -225 ±75 mVDC
.
When invalid information is
present (Flag IN VIEW) the TO/FROM output is 0 ±10 mVDC
.
