1 System Overview
1.1 System Description
The Astronautics Flight Instrument (AFI) 4700 is a 5” by 7” Electronic
Flight Instrument (EFI) designed to replace and improve upon the
legacy electromechanical Attitude Director Indicator (ADI) and
Horizontal Situation Indicator (HSI).
Figure 1-1: System Description
The AFI4700 is designed to interface with existing and/or retrofit
attitude and heading units, navigation radios, GPS systems, etc. A list
of compatible equipment is found in the installation manual.
The EFI is capable of displaying several HSI overlays to consolidate
situational awareness information normally available in different
locations in the instrument panel to the AFI4700.
PLG12863E AFI4700 Pilot’s Guide 10
PLG12863E AFI4700 Pilot’s Guide 11
1.2 System Power Up
Initial power up displays color bars on the screen. After several
seconds, the color bars are replaced by the flight application.
During aircraft power up, the display may start faster than other
systems, such as gyros, resulting in a time delay between power-up
and the system receiving valid signals. During this time, the display
will present color bars for a short time followed by failure warnings on
the ADI and HSI sections. After valid signals are received, the display
will begin functioning normally.
Figure 1-2: System Power Up
PLG12863E AFI4700 Pilot’s Guide 12
1.3 System Operation
The AFI4700 is an EFI whose design consolidates the ADI and HSI
information with the addition of Radar Altitude, Traffic Collision and
Avoidance System (TCAS), Global Positioning Satellite (GPS), and
VHF Omnidirectional Range (VOR) map overlays, display of Weather
Radar, external Terrain Awareness and Warning System (TAWS), and
a Physical Slip/Skid Indicator.
To interact with these features the display unit includes eight (7) bezel
buttons one (1) brightness rocker button, and two (2) rotary knobs that
rotate and push.
The bezel layout shown in Figure 1-3 describes the multiple bezel
buttons and rotary knobs on the AFI4700.
Figure 1-3: System Layout
Left Rotary Knob
The left rotary knob performs two functions. Rotating the knob in
normal operation changes the selected course, and pressing the knob
synchronizes the selected course with the bearing of the selected
PLG12863E AFI4700 Pilot’s Guide 13
navigation source. When navigating the menu, the left knob scrolls
through the page selections.
Right Rotary Knob
The right rotary knob is used to adjust the selected heading. Rotating
the knob moves the heading bug around the compass card and
pressing the knob synchronizes the heading bug with the current
heading.
When in the Decision Height (DH) menu and DH is configured for
rotary on the configuration page, the right rotary knob adjusts the DH
value.
Adjust Brightness
On the upper right-hand corner of the AFI4700 is a rocker switch used
to adjust the brightness of the display.
Left Multifunction
The left bezel button toggles the Weather Radar, Terrain, and Lighting
Detection overlay when configured.
Center Multifunction
The center bezel button toggles map mode ON and OFF. The map
overlay can be used to display map information from the GPS, or VOR
station when DME is provided.
Right Multifunction
When the AFI4700 is configured to display Traffic Collision and
Avoidance (TCAS) information, this bezel button toggles TCAS
overlay On and Off.
Menu Button
The lower left hand bezel button commands the system menu to open
and close.
Range Increase and Decrease
The center two bezel buttons along the bottom row of bezel buttons
adjust the map range.
PLG12863E AFI4700 Pilot’s Guide 14
Navigation Source Select
The lower right-hand bezel button allows the primary navigation
source to be selected from the list of available navigation sources.
Inclinometer
In the center along the top bezel is a physical ball in a tube
inclinometer, which displays slip or skid.
USB Port
The USB Port along the top of the bezel allows access to run
maintenance and diagnostics on the EFI, as well as to update
databases.
1.3.1 Using the System Menu
Selecting the Menu button displays a page with a list of items, which
can be cycled through using the left rotary knob. Options can be
chosen by pressing the corresponding left or center bezel button
directly below the selection. Pressing the menu bezel button closes
the menu.
Menu Headings:
BRGS
The bearings menu page allows the preview of one or two navigation
sources overlaid on the compass. The left bezel button selects
between OFF, VOR/ILS1, GPS1, ADF, DF. The center bezel button
selects between OFF, VOR/ILS2, GPS2, ADF, DF.
DH
Adjusts the decision height UP or DOWN. DH values range from 10ft
to 1000ft in 1ft increments from 10-200ft and 10ft increments from
200-1000ft.
Figure 1-4: System Menu
PLG12863E AFI4700 Pilot’s Guide 15
DISP
Change the compass between a full mode showing 360° and arc
mode showing 120° with the left bezel button (ARC/FULL). When the
weather overlay is selected, alternates between 360° compass and
vertical profile mode with the center bezel button (VP).
LX
Provides an option to clear lightning icons when the map is displayed
with the left bezel button (CLEAR).
HSYNC
Hold the left bezel button (SYNC) for three seconds to enter Horizon
Sync mode.
TEST
The left bezel button (RA) executes a test of the radar altimeter, if
equipped. The center bezel button (MAINT) enters the EFI Status
page. The EFI Status page is only available when the aircraft is on
ground.
PLG12863E AFI4700 Pilot’s Guide 16
1.3.2 Navigating the System Menu
After selecting the MENU bezel button, the MENU Page is displayed
where six (6) pages can be cycled using the left rotary knob. Select
the page items by using the left and center multifunction keys.
Figure 1-5: System Menu Navigation
PLG12863E AFI4700 Pilot’s Guide 17
1.3.3 Navigating the Maintenance Menu
When the MAINT option is selected from the System Menu, additional
information is displayed in the EFI STATUS page. MAINT is only
selectable when the aircraft is on ground. This page contains a further
sub-menu from which maintenance related functionality can be
accessed.
Figure 1-6: Maintenance Menu Navigation
1.3.4 Display Dimming Control
The brightness of the display unit can be adjusted manually through
the brightness rocker button in the top right corner of the bezel to
compensate for ambient lighting conditions. Press the left side of the
rocker button to dim and the right side of the rocker button to brighten.
1.3.5 Bezel Dimming Control
Bezel lighting brightness is controlled externally from the flight deck
bezel lighting control.
1.3.5.1 Night Vision Mode
The AFI4700 is equipped with a Night Vision (NVIS) mode where a
separate secondary NVIS LED activates instead of the daylight
backlight. This NVIS backlight is designed to meet MIL-STD-3009,
Type II class B White and Max for multi-color displays. Night vision
mode is activated via a discrete switch wired to the display.
PLG12863E AFI4700 Pilot’s Guide 18
1.3.6 Crosslink
When more than one display is installed, the AFI4700s will
communicate with each other via an RS-422 serial interface crosslink
bus. In order to provide assurance of data accuracy, the EFIs
constantly compares attitude, heading, localizer, glideslope, and radar
altimeter information between the two displays. The crosslink bus also
allows the display of offside attitude and heading.
