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)
