CESSNA 400 GLIDE SLOPE
(TYPE R-443B)
TYPICAL 300 SERIES GLIDE SLOPE INDICATORS
1. GLIDE SLOPE DEVIATION POINTER - Indicates deviation from normal glide
slope.
2.
GLIDE SLOPE "OFF" OR "GS" FLAG - When visible, indicates unreliable glide
slope signal or improperly operating equipment. The flag disappears when a
reliable glide slope signal is being received.
CAUTION
Spurious glide slope signals may exist in the area of the localizer
back course approach which can cause the glide slope "OFF" or
"GS" flag to disappear and present unreliable glide slope informa-
tion. Disregard all glide slope signal indications when making a
localizer back course approach unless a glide slope
specified on the approach and landing chart.

EMERGENCY PROCEDURES
There is no change to the airplane emergency procedures when this
avionic equipment is installed.
SECTION 4
NORMAL PROCEDURES
TO RECEIVE GLIDE SLOPE SIGNALS:
The pilot should be aware that on many Cessna airplanes
equipped with the windshield mounted glide slope
antenna, pilots should avoid use of 2700 ±100 RPM on
airplanes equipped with a two-bladed propeller or 1800
±100 RPM on airplanes equipped with a three-bladed
approaches to avoid oscillations of
propeller during ILS
the glide slope deviation pointer caused by propeller
interference.
1. NAV Frequency Select Knobs -- SELECT desired localizer fre-
quency (glide slope frequency is automatically selected).
2. NAV / COM VOX-ID-T Switch -- SELECT ID position to disconnect
filter from audio circuit.
3. NAV VOL Control -- ADJUST to desired listening level to confirm
proper localizer station.
CAUTION
"
When glide slope "OFF
indications are unusable.
