A helpful quick reference reminder of the localizer course is to set the course on the
omni-bearing readout.
3.1.3 GLIDESLOPE OPERATION (KI 209)
The glideslope (horizontal) needle provides the pilot with vertical steering information
during ILS approaches. The glideslope circuitry may be energized independently or
when the associated localizer frequency is selected on the navigation receiver. Ob-
serve that the glideslope warning flag is concealed. The glideslope needle deflects to-
ward the direction the pilot must fly to remain on the glideslope path. If the glideslope
needle deflects upward, the aircraft is below the glideslope and must climb to center
the needle. If the needle deflects downward, the aircraft is above the glide path and
must descend to remain on the glide path. When the needle is centered the aircraft is
on the glide path.

functions of the KI 209.
3.2.1 OMNI-BEARING SELECTOR (OBS)
The OMNI Bearing Selector knob rotates the azimuth card on which the desired
course is selected. The course selected serves as a reference for all VOR indications.
The reciprocal course is identified under the bottom course index.
3.2.2 VOR/LOC DEVIATION INDICATOR
The VOR/LOC needle deflection indicates the amount of deviation from the selected
VOR course or localizer path. The indicated angular deviation is toward the proper
flight path in normal operation.
The VOR/LOC warning flag is fully visible when the VOR or LOC signal is unreliable.
The VOR TO-FROM flag indicates the direction "TO" or "FROM" the VOR station.
3.2.3 GLIDESLOPE DEVIATION INDICATOR (KI 209 Only)
The glideslope deviation needle deflection indicates the amount of deviation from the
glide path. The deflection is toward the direction of flight required to maintain the prop-
er descent path. The glideslope warning flag is visible when the glideslope signal is
unreliable or the receiver has malfunctioned.
