CESSNA 300 NAV/COM
(TYPE RT-385A)
VOR SELF-TEST OPERATION:
1. COM OFF/VOL Control -- TURN ON.
2. NAV Frequency Selector Switches -- SELECT usable VOR station
signal.
3. OBS Knob -- SET for 0° course at course index; course deviation
pointer centers or deflects left or right, depending on bearing of
signal; NAV/TO-FROM indicator shows TO or FROM.
4. ID/ VOX/T Switch -- PRESS to T and HOLD at T; course deviation
pointer centers and NAV/TO-FROM indicator shows FROM.
5. OBS Knob -- TURN to displace course approximately 10° to either
side of 0° (while holding ID/ VOX/ T to T). Course deviation pointer
deflects full scale in direction corresponding to course displace-
ment. NAV/TO-FROM indicator shows FROM.
6. ID/VOX/T Switch -- RELEASE for normal operation.
This test does not fulfill the requirements of FAR 91.25.

PERFORMANCE
There is no change to the airplane performance when this avionic
equipment is installed. However, the installation of an externally mounted
antenna or several related external antennas, will result in a minor
reduction in cruise performance.

(Type RT-359A)

OPTIONAL ALTITUDE ENCODER (BLIND)
SECTION .
GENERAL
The Cessna 300 Transponder (Type RT-359A), shown in Figure 1, is the
airborne component of an Air Traffic Control Radar Beacon System
( ATCRBS). The transponder enables the ATC ground controller to "see"
and identify the aircraft, while in flight, on the control center's radarscope
more readily.
The Cessna 300 Transponder system consists of a panel-mounted unit
and an externally mounted antenna. The transponder receives interroga-
tion pulse signals on 1030 MHz and transmits pulse-train reply signals on
1090 MHz. The transponder is capable of replying to Mode A (aircraft
identification) and also Mode C (altitude reporting) when coupled to an
optional altitude encoder system. The transponder is capable of replying
on both modes of interrogation on a selective reply basis on any of 4,096
information code selections. The optional altitude encoder system (not
part of a standard 300 Transponder system) required for Mode C (altitude
reporting) operation consists of a completely independent remote-
mounted digitizer that is connected to the static system and supplies
encoded altitude information to the transponder. When the altitude encoder
system is coupled to the 300 Transponder system, altitude reporting
capabilities are available in 100-foot increments between -1000 and +20,000
feet.
All Cessna 300 Transponder operating controls are located on the front
panel of the unit. Functions of the operating controls are described in
Figure 1.
