INTRODUCTION
Introduction
This pilot’s guide describes the
components, operation, and
operational procedures of the
BENDIX/KING EFS 40/50 Electronic Flight Instrumentation System (EFIS) containing system
software 04, 05, 06, 07, 08, 09,
10, 11, 12, 13, 14, 15, and 16.
The EFS40 system uses either a
single control display unit, four
inch ED 461, or a separate
C P 467 mode controller and four
inch ED 462 display unit for control and display of navigation data
and sensor selection. When a
Multi-Function Display is incorporated in the system, the
C P 469/A will control and select
navigation data for display on the
MFD. A CP 466A or CP 4 6 6 B
Equipment covered in this pilot's guide includes:
E D 4 6 1Control display unit, 4" X 4"
E D 462 Display unit, 4" X 4"

C P 4 6 9 AMFD control panel with Checklist,
TCAS and Joystick features
C P 4 7 0EADI brightness and DH set and test panel
E D 5 5 1Display unit, 5" X 5" (not available in current production)
E D 5 5 1 ADisplay unit, 5" X 5" (~16% larger symbols
compared with ED 461/2 presentation)
provides the radar control function when an RDS 81/82/84 or 86
weather radar is interfaced with
the system, and the associated
radar control/display unit is not
i n s t a l l e d .
The EFS 50 system uses a
remote CP 467 mode controller
and an ED 551/A display unit for
control and display of navigation
data and sensor selection. The
remote SYMBOL GENERATOR,
S G 464 or SG 465, interfaces
with the navigation sensors to
compute the display and EFIS
output data required by other
systems on board the aircraft.
The SG 464 is no longer available and has not been produced
with software versions 08 or later.
An Abbreviated Operations
section included in this manual
covers the functions of the EFS

features and push button operations. However, it is necessary to
read the entire Pilot’s Guide for a
full understanding of the
E F S 40/50 system.
N o t e : The EFS 40/50 display
illustrations used in this pilot's
guide are artist's reproduc tions. Extreme care has been
taken to ensure the accuracy
of symbology placement and
relative size. However, it is
impossible to exactly duplicate
the display of a CRT and com pensate for all brightness lev els, as line width displayed on
the CRT varies with bright ness. In many cases, unrealis tic displays provide the most
informative display possible on
a single display. Therefore,
we ask that you use and treat
the graphic illustrations con taine
d in this pilot's guide as
they were intended. These
illustrations are to familiarize
the pilot with the type and
placement of data to be provid ed by the EFS 40/50.
ED 551A is the only version in
current production.
The data presented in this
pilot’ s guide is general in
nature and not tailored toward
a specific installation. Not all
equipment interfaces nor dis play options presented are cer tifiable in all aircraft types or by
all certification agencies. Each
installation may incorporate
different equipment comple ments and use different dis play options. For the unique
certified operating procedure
of a particular aircraft, refer to
the appropriate approved
Flight Manual Supplement for
that aircraft.

SYSTEM CONFIGURATION
System Configuration
GENERAL
Various configurations of the
E F S 40/50 system are currently
available to fulfill the particular
needs of the user. These configurations are differentiated by the
number of display units, type of
mode controller, number of symbol generators and the interfacing equipment.
The basic EFS 40 ( 2 tube four
inch Electronic Flight Instrumentation System) consists of:
• 1ea EHSI Control/Display
Unit (ED 4 6 1 )
• 1 ea EADI Display
Unit (ED 4 6 2 )
• 1 ea EADI control
panel (CP 4 7 0 )
• 1 ea Symbol Generator
( S G 4 6 5 )
• Or 1 ea remote EFIS
Control Panel (CP4 6 7 )
• 1 ea EHSI Display
Unit (ED 4 6 2 )
• 1 ea EADI Display
Unit (ED 4 6 2 )
• 1 ea Symbol Generator
( S G 4 6 5 )
The basic EFS 50 (2 tube five
inch Electronic Flight Instrumentation System) consists of:
• 1
ea remote EFIS Control
Panel (CP 467)
• 1 ea EHSI Display
Unit (ED 5 5 1 A ) ,
• 1 ea EADI Display
Unit (ED 5 5 1 A )
• 1 ea Symbol Generator
( S G 4 6 5 )
Beginning with software 09, a
configuration option was added
allowing an MFD only installation.
This option removes the heading
bug from the display allowing the
MFD SG to stand alone without
any other symbol generator in
the installation. The display unit
in this case can be either an ED
462 or ED 551A. The control
panel must be a CP 469A.
o MFD ONLY - no selected
heading bug.
Two new configuration options
for display unit (DU) type were
also added with software 09.
These options allow the MFD SG
to drive a 5” ED 551A MFD during normal operation and change
to eit
her ED 461 or ED 462 EHSI
and ED 462 EADI during standby

if VOR 1 is being displayed and
the 1-2 button is pressed, VOR 2
will become the displayed sensor. If only one sensor is
installed, the display will not cycle
and the sensor annunciation will
not show a system number. For
example ADF would be displayed
(not ADF 1) in installations containing a single ADF.

SENSOR SELECT
During installation, the EFS
40/50 symbol generator was programmed with the type and
quantity of each piece of interfacing equipment. Not all the
equipment interfaced to the EFS
40/50 is usable for primary navigation. The EFS 40/50 creates
and maintains in permanent
memory a list of the interfacing
navigation sensors.
The NAV push button is used to
select which NAV sensor provides primary navigation data. A
press of the NAV sensor select
button sequentially selects the
next available sensor from the list
of those installed. Primary Navigation Data is defined as the dis-
tance in the upper right corner,

and it is not active in the sys tem. A yellow FUNCTION
NOT IMPLEMENTED will be
displayed in the center of the
screen.
The Primary Navigation Sensor
is annunciated at the side of the
display unit opposite the vertical
scale. Only those sensors interfaced to the EFS 40/50 in a specific installation will be selectable
for use and display.
For installations with dual
VOR/ILS receivers and a KNS
81, the KNS 81 will be programmed as an RNAV. The
annunciation displayed on the
EHSI for this configuration will be
NAV and will not change as
modes on the KNS 81 are
changed. The sensor annunciation and associated navigation
data colors will change to match
the normal enroute or approach
color scheme, green for on-side
approach navigation data, cyan
for on-side non approach navigation data and yellow for off-side
navigation data.
S o f t w a r e 04 added two new helicopter navigation sensor options,
Doppler (DOPP) and Cable
(CAB). These sensors require
unique display formats, therefore
when they are selected for display their unique format will be
presented and are not changeable by the HSI or ARC button.
The following is an all-inclusive
list, in order, of primary navigation sensors that may be interfaced with the EFS 40/50:

lightning detection presentation.
If a compatible weather radar or
lightning detection is not
installed, the weather option will
not be in the sequence.
The EFS 40/50 EHSI has four
possible 360-degree display formats: standard HSI compass
rose, NAV map, NAV map with
weather, and DG mode. Each
press of the HSI button sequentially selects the next display format. A press of the HSI button
while in the ARC mode will
change the display to the standard HSI compass rose.
Software release 05 added a
Heading Bug to the DG mode.
Primary use of this display format
is for training or as an option to

Once Vertical Profile is selected,
the desired profile-azimuth angle
may be changed in two degree
increments by pressing and holding the appropriate TRK button.
One of two things will happen
when a TRK button is pressed:
(1) If the radar’s antenna is
already profiling, the antenna will
move in the two-degree increments, “slicing” in the direction
determined by the TRK button; or
(2) A “WAIT” annunciation will be
displayed indicating that the

desired “slicing” function as soon
as the antenna returns to the last

Depending on the software version of the RDS VP radar and
the system installation, the antenna may also scan horizontally
while in the VP mode. If the
antenna is not sweeping vertically when the TRK button is
pressed, a “WAIT” annunciation
will be displayed until the antenna returns to the last vertical
“slice” azimuth.

Beginning with EFS software version 09, a Split Screen mode is
added to the VP button selection
sequence immediately following
the Vertical Profile mode. During
this Split Screen mode the EFS
will toggle the antenna between

every 6 seconds, allowing both to

Note: This Split Screen mode is
an operational enhancement
added to EFS 09 software that
does not require any modifica tion to the existing RDS

weather presentation, only the
yellow dashed line will be displayed.
For VP operations, the TRK button performs two functions. 1.)
Prior to engaging VP, the appropriate button (left or right) is used
to place the track line at the
desired azimuth angle to be vertically scanned (sliced). When VP
is engaged, the slice will be taken
at the last position of the track
line, whether it is visible or not. If
the track line has not been
selected after power has been
applied to system and VP is
engaged, the slice will be taken
at 0 degrees (directly in front of
the aircraft). 2.) When
mode, pressing the TRK will
change the selected azimuth
two-degrees left or right, depending on which button is pressed.
Continuously holding the TRK
button will result in the system
“slicing” in two-degree increments, called continuous profile.
Continuous profile is not used on
the RDR2 0 0 0 .
Beginning with EFS software version 09, the Drift Angle Track feature can be activated on the MFD

the joystick will create a waypoint
cursor ahead of the aircraft on
the half range ring at the current
heading. This will be true for both
HSI and ARC display formats.
The cursor will be a standard
white waypoint symbol. Movement of the waypoint will be in
any of the eight directions commanded by the joystick. The rate
of movement will start off slow

However, a change of primary
NAV sensor or display modes will
reset the invisible cursor location
to its initial starting position.

EHSI DISPLAYS
EFS 40/50 COLOR STANDARDS
The EFS 40/50 uses a defined color set which aids the pilot in interpreting displayed information. A brief summary of the color set is as
f o l l o w s :
For an example of the color usage, refer to figure 4.1.3 at the back of
this section, Typical EFS 40/50 EHSI Color Displays.
STANDARD EHSI DISPLAYS
Refer to Figures 4.1.5 and 4.1.6
while reviewing STANDARD
EHSI DISPLAYS.
NORMAL COMPASS CARD
360° rotating white compass
scale indicates aircraft heading
referenced to white triangular
heading index (lubber line). The
compass scale is divided in 5degree increments with the 10degree divisions being approximately twice as long. Fixed

45-degree index marks are adjacent to the compass scale.
Free DG (directional gyro) operation will be annunciated by a yellow FDG (or FHDG) to the left of
the lubber. The Free mode
annunciation will only be supported in installations with an ARINC
429 AHRS (Attitude Heading
Reference System) that supports
the Free DG (directional gyro)
mode of operation via the digital
data bus.

changed the DG annunciation
to HDG to better describe the
variety of heading sources that
may be interfaced with the
E F S 40/50, ie. INS, AHRS
and conventional gyros.
Dual selectable compass inputs
are provided for. If a second
compass system is installed, the
cross-side source is selected by
means of a remote mounted
switch. Once the alternate compass source has been selected,
a yellow DG1 (HDG1) or DG2
(HDG2) will be displayed to the
left of the lubber line.
In a dual EFS 40/50 installation
with software release 04 or 05, if
both systems use the same
heading source, annunciations
will appear on both EHSI’s alerting the pilots they have the
source selected. The EHSI that is
using its normal heading source
will annunciate a yellow “DG”
with a yellow box around it to
indicate that its primary heading
source has been selected for use
on the other EHSI. The EHSI that
is using its alternate heading
source will annunciate a yellow
“DG1” or “DG2” as applicable
with a yellow box around it to
indicate the heading source
being used is the same one
being used by the other EHSI.
For example, if the co-pilot were
to select his alternate heading
source, heading #1, “DG1” would
appear with a box around it on
th
e co-pilot’s EHSI and DG would
appear with a box around it on
same
the pilot’s EHSI.
In a dual EFS 40/50 installation
with software release 06 and
above, if both systems select the
same heading source, a yellow
“HDG1” or “HDG2” with a yellow
box around it will appear on both
EHSIs alerting the pilots that they
have the same source selected.
Figure 4.1.1
SAME HEADING SOURCE
SELECTION
When two compass sources are
available, the two inputs are
compared for agreement. If the
two inputs do not fall within 6degrees of each other while in
level flight, a yellow comparison
warning, HDG under a doubleended arrow, will be annunciated
to the right of the lubber line.
See figure 4.1.5, EHSI SYMBOL
DEFINITION.
NAVIGATION SOURCE
ANNUNCIATION
A vertical three- or four-letter
alphanumeric readout located on
the left or right side of the display, depending on vertical scale
side selection, indicates the system selected as the primary navigation sensor.
For dual sensor installations the
cross-side navigation system
may be selected by pressing the
1-2 push button. Example: pilot

button will not be active if the
system configuration does not
support two of the same type

Green annunciations indicate an
on-side approach NAV system or
an enroute NAV system which
has been approved for approach
use is being displayed. Yellow
indicates the cross-side system
has been selected. Cyan annunciations apply to on-side nonapproach LNAV systems. These

Software release 06 incorporated
the ability to interface with the
TACAN version of the KNS 8 1
and annunciate TCN when the
K N S 81 is in the TACAN mode
of operation.
If both sides select the same
navigation source, (i.e., pilot and
co-pilot select VOR 2) a yellow
box is placed around the navigation source annunciator on both
E H S I ‘ s .
If both sides select their respective cross-side navigation source
(i.e., pilot selects system 2, copilot selects system 1) then both

HEADING SELECT “BUG”
A notched heading bug is manually rotated around the compass
scale by the heading select knob
on the control panel. In the 360degree compass mode a full time
digital readout of the selected
heading is displayed below the
vertical deviation scale position.
In the ARC mode, a digital heading readout is displayed when the
heading bug is not completely in
view. The digital readout will be
positioned just inside the compass scale on the side nearest
the heading bug. Once set, the
heading bug rotates with the
compass card. The heading bug
is used to indicate desired heading and provides selected heading reference for autopilot steeri n g .
A RED X will be drawn through
the heading bug if there is a
he
ading select knob failure on
the EFS 40/50 control panel.
Software release 06 added the
options, selectable at the time of
installation and certification, to
select one of three heading bug
and digital readout color choices:

Prior to software 06, the heading
bug and selected heading readout are always orange. The
heading bug is not displayed in
MFD only installations. This
became an EFS system configuration option with software 09.
COURSE SELECT
The CRS control knob rotates the
course pointer about the compass scale and sets digital
course readout. Once set, the
course pointer rotates with the
compass card. The selected
course indicates desired navigation course to be flown. Depending on the LNAV (long range navigation) installed, the course
pointer may automatically be
positioned to the DTK (desired
track) when LNAV is selected as
the primary sensor. When LNAV
is the selected sensor and DTK
is displayed, the EFS 4 0 / 5 0
course select knob is disabled.
In the upper left corner of the display, an alphanumeric
annunciates the letters CRS and
indicates the selected navigation
course in degrees. When in a
NAV map display mode, the
course pointer will not be displayed, the alphanumeric readout
will be the only reference for the
selected course.
