System Overview 1-1
1 System Overview
This manual assumes that the pilot is appropriately licensed, is
proficient in operation of the aircraft and its equipment, and is in
compliance with all Federal Aviation Regulations (FARs).
All images contained in this manual are for reference use only,
and are subject to change.
Avidyne strongly recommends that pilots use the IFD540 system
only under VFR conditions until completely familiar with its
operation and use.
Boxed areas marked as NOTE within this manual identify certain
situations or areas of operation having heightened safety
implications. While it is important for the operator to be familiar
with all of the information in the manual, it is essential to the safe
use of the IFD540 that pilots give careful attention to the material
contained within these NOTEs.
In order to avoid a diversion of attention from the task of safely
taxiing, pilots should avoid performing the described cockpit tasks
while the aircraft is in motion on the ground. It remains the pilot’s
duty to monitor the IFD for proper function upon activation and
during use.
Internal IFD540 data logs and the storage devices that record and
store data are property of Avidyne.
IFD540 Integrated Flight Display

1-2 System Overview
INTENDED FUNCTION
The Avidyne IFD540 is a GPS-nav-com radio whose primary
function is to conduct nav-com tuning and communication, and
serve as the principal navigation sensor/system for all IFR VHF
(“VLOC”) and GPS-based navigation and instrument flying
(enroute and approach), provided it is either installed in the
“primary field of view” or is connected to an external CDI/HSI
indicator that is installed in the “primary field of view” as well as a
remote source selection annunciator.
Supplemental functions include serving as a moving-map flight
management system (FMS), and electronic charts and checklists
along with a number or timer and calculator types of utilities.
FUNCTIONAL OVERVIEW
The Avidyne IFD540 Integrated Flight Display (IFD) system
supports the following functions:
 Flight Management System (FMS)
 WAAS and non-WAAS GPS Navigation
 VHF Radio Nav/Com (16W and 10W variants)
 Moving Map
 Terrain Awareness and Forward Looking Terrain
Alerting
 Weather Datalink and Lightning sensor depictions
 Traffic
 Electronic Approach Plates
 Electronic Checklists
 Data Logging
 Caution Advisory System (CAS)
 Utilities (e.g. Schedulers, Timers, Calculators)
 Multi-touch Touch screen Control
 Multiple IFD Operations

System Overview 1-3
COOL FEATURE
Multi-Touch Touch Screen Control
The IFD supports multi-touch touch screen
technology meaning that features such as two-
fingered pinch zoom for range changing on maps
and charts is fully enabled.
The system has been designed for single-pilot IFR operation and
features a Page and Tab user interface.
Most functions revolve around the three Page Function Keys
that appear across the bottom edge of the bezel. Each of the
three functional pages has associated tabs, which contain related
data, often in different views. These functions and tabs are
covered in detail throughout this reference manual.
BASIC CONCEPTS
PAGE FUNCTION KEYS
The 3 buttons along the bottom of the IFD bezel are called Page
Function Keys. Each key is labeled by function:
 FMS (Flight Management System)
 MAP (Moving Map)
 AUX (System Pages)
Each page has a number of associated tabs. Each Page
Function key has a left and right rocker nature to it. Select the
page of interest by pressing the middle of the Page Function Key
and navigate through the available tabs by pressing the left or
right side of the Page Function Key. Continual pressing of one
side of the function key will automatically step through the tabs.
Page Function Keys and Tabs

1-4 System Overview
LINE SELECT KEYS
Line Select Keys, typically abbreviated to LSK in this manual,
are the buttons found along the left vertical side of the bezel.
These are different from Page Function Keys in that they also
have a label, just inside the bezel adjacent to the physical LSK
which indicates the function of the LSK. Pressing the LSK or
touching the LSK label on the display either performs the labeled
action or changes the state. For the cases where there is a list of
selectable options, browse the list by pressing the LSK.
LSK Types
 State LSKs – Green button title in the first row
and a white state display in the second row
indicates a list of choices. Traverse the list in one
direction by pressing the line select key or in the
other direction by touching the label.
 Action LSKs – Pressing the LSK or display label
enables the action indicated on the label.
LSK Types
RIGHT KNOB LABELING
The bottom right IFD knob is a modal knob in that its function is
context dependent and is “soft-labeled” on the display. As a
general rule, the inner and outer rings of the dual concentric knob
perform the same function – it’s just that the inner ring is “fine”
control and the outer ring is “coarse” control of that function. The
symbol used to represent the right knob is a ring with a center
dot.
State LSKs – Push the
button or touch the label
to cycle through the list of
choices
Action LSK – Press the
button or touch the label
to engage an action (bring
up Wx Overlay on map)

System Overview 1-5
Right Knob Label Scheme
In the example above, the outer ring scrolls through a list in a
coarse manner and the inner ring scrolls through the same list
stopping at each minor field along the way. Pushing the knob
generates a drop-down menu.
COLOR PHILOSOPHY
There are a few generalities with the use of color that are
consistent across the IFD as described in the table below:
IFD Feature/Function
Color
Page Function Keys
Green – Active;
White – Available but not
currently active.
Note: AUX can also be
Red, Yellow or Cyan if there
is an active alert as
described later in this
manual.

1-6 System Overview
GENERAL IFD OPERATIONS
The IFD540 Integrated Flight Display (IFD) is a touch screen
GPS-Nav-Com that has been designed to be both a retrofit GPS-
Nav-Com or a clean install GPS-Nav-Com. As a retrofit
installation, the unit was designed to be plug-and-play compatible
with a Garmin 530/W unit.
BEZEL LAYOUT
Starting in the top left corner and working counter-clockwise
around the bezel, the IFD540 has:
 Power/Volume/Squelch knob;

downloads, software updates and powering USB
devices in-flight;
 Four (4) Line Select Keys (LSKs) that are page
dependent with soft key labels adjacent to each;
 Dual Concentric Rotary Knob as a means of
manually tuning Com and Nav frequencies;
 Three (3) Page Function keys along the bottom
(FMS, MAP, AUX);
 Mechanical Cam Latch control for tray installation;
 Dual Concentric Rotary Knob that is page
dependent;
 Six (6) Dedicated Function Keys consisting of:
o Direct-To (“-D->”)
o Procedure (“PROC”)
o Nearest (“NRST”)
o Frequency List (“FREQ)
o Enter (“ENTR”)
o Clear (“CLR”)
 Ambient Light Sensor;
 CDI Nav Source knob.

1-8 System Overview
POWER CONTROL
The IFD is regulated by a pair of circuit breakers. There is also a
power control on the top left corner of the unit but the IFD will
automatically start when the aircraft bus power is applied. The
power button can be used to turn the unit off (press and hold and
watch 5 second count down expire) or to turn the unit back on if it
had been manually turned off.
Manual Power Down
After power application, the bezel keys backlighting will be turned
on. Several seconds later, the IFD display will begin to have
indications.

System Overview 1-9
BRIGHTNESS CONTROLS
Each IFD has brightness controls to control both the bezel and
the display brightness. The user can access individual controls to
allow for either manual control of brightness, automatic control of
brightness in response to the cockpit dimming controls/rheostats
or automatic control of brightness in response to the ambient light
sensor that is embedded in the bezel. The controls for all are on
the AUX page using the User Options LSK of the Setup tab.
Brightness Controls
If the IFD540 appears “inoperative” or non-responsive from a
lighting perspective, check the aircraft instrument lighting rheostat
to ensure it is not set to a night position.

1-10 System Overview
START-UP SEQUENCE
The startup sequence of the IFD is as follows:
 A splash screen will be displayed during system
initialization and will be automatically removed
when the IFD is initialized. The Page Function
keys (e.g. FMS, MAP, AUX) will not be lit up while
the splash screen is present;
 An agreement of the limitation of your legal rights
must be made via the bezel “ENTR” button. Note:
For the duration that the agreement page is
displayed, the IFD is activating the signals that
connect with a remote annunciator panel as well
out outputting self-test data to external devices.
Use that condition as a lamp test and external
signal check;
 A software version and database currency page is
displayed IF there any expired databases.
Avidyne does not recommend operating with
expired databases but the system will allow
operation by pressing the “Proceed” followed by
the “Confirm” LSKs;
 If there is a fuel flow system connected to the IFD,
then the IFD will automatically transition to the
Fuel Management Page. If the fuel flow system
does not provide fuel totalizer data, you will need
to input the fuel on board and press the “ENTR”
key. If the fuel flow system does provide fuel
totalizer data, confirm the total is correct and press
the “ENTR” key.
If there is no fuel flow system connected, then the
unit progresses directly to the FMS page and FPL
tab, in principle ready for a flight plan to be loaded
or verified;
 The IFD is now ready for normal use.
The agreement page, database expiration and fuel management
entries are all skipped if the unit is powered on in-flight.

System Overview 1-11
NOTE
Some Data May Be Delayed at Startup
Some data such as fuel flow and fuel totalizer may
experience a 5-10 second delay during post start
initialization. For those aircraft configured with fuel
totalizers, this may result in some fuel display
changes on the Fuel Mgmt tab during that period
including prompting the pilot to enter in initial fuel.
That should resolve itself within a few seconds.
Another example concerns the FMS nav database
initialization. In this case, the message “Please wait
– System Initializing” may be displayed on the FPL
tab for 10-30 seconds. Additionally, if the unit has
been exposed to extreme cold prior to start, it may
take a warm up period to achieve standard
performance.
TIPS AND TECHNIQUES
Manual Check of Database Dates
Even if the databases are all current, you can still
view the date/status of each database from the AUX
page, Database Status display as described in
Section 4 of this manual.
TIPS AND TECHNIQUES
“GPS No Position” Message Possible at Startup
If the GPS alignment takes an unusually long time
(e.g more than 2 minutes) to acquire an initial
position fix, the “GPS No Position” advisory
message will be displayed. This message will
automatically clear itself when a fix is acquired. If
the message does not remove itself by the time you
are ready to taxi, it is a clear indication that your
system has not determined its initial position and
action may be required on your part.

1-12 System Overview
DATABASE CURRENCY STATES
The following table describes the various database currency
states that may be observed at startup:

NOTE
Use of Not Yet Effective Data
If attempting to use not-yet-effective data (e.g.
charts or nav), it is the responsibility of the pilot in
command to verify there are no differences between
the current data and the not-yet-effective data
before it is permissible to use the not-yet-effective
data.

System Overview 1-13
PAGE LAYOUT AND FORMATS
The left column (radio frequencies and context-sensitive line
select keys), top data strip and nav source knob indication, and
bottom edge set of page tabs are always displayed on every
page.
Page Layout
Use a combination of the page function keys (FMS, MAP, AUX)
and the associated tabs, to change the contents of the rest of the
display.
Each page has a number of associated tabs. Each Page Function
key has a left and right rocker nature to it. Select the page of

navigate through the available tabs by pressing the left or right
side of the Page Function key. The desired tab can also be
touched to directly jump to that tab. The last tab selected on any
given page is retained in memory and will be displayed when you
return to that page.
COOL FEATURE
Split Pages
The split pages where extra data can be displayed
along the right edge can be handy pages in all
phases of flight.
Some pages can display a data strip along the right edge of the
display. The FPL tab and NRST tab on the FMS page and the
Map tab on the MAP page are prime examples. In the cases
where this is available, a labeled side tab is displayed. That extra
data strip can be pulled out for display or pushed back in for
hiding by using any of the following methods:
