WARNINGS,

CAUTIONS, AND NOTES

WARNING: Navigation and terrain separation must NOT be predicated upon the use of the TAWS function. The
TAWS feature is NOT intended to be used as a primary reference for terrain avoidance and does not relieve the
pilot from the responsibility of being aware of surroundings during flight. The TAWS feature is only to be used
as an aid for terrain avoidance and is not certified for use in applications requiring a certified terrain aware­ness system. Terrain data is obtained from third party sources. Garmin is not able to independently verify the
accuracy of the terrain data.

WARNING: The terrain data should be used only as an aid for situational awareness. Terrain data must not

be used as the sole basis for decisions or maneuvers to avoid terrain or obstacles. Terrain data must not be
used for navigation.

WARNING: The altitude calculated by GNS 530 GPS receivers is geometric height above Mean Sea Level and
could vary significantly from the altitude displayed by pressure altimeters in aircraft. GPS altitude should never
be used for vertical navigation. Always use pressure altitude displayed by pressure altimeters in the aircraft.

WARNING: The Jeppesen database used in the GNS 530 system must be updated regularly in order to ensure
that its information remains current. Updates are released every 28 days. A database information packet is
included in the GNS 530 package. Pilots using an outdated database do so entirely at their own risk.

WARNING: The basemap (land and water data) must not be used for navigation, but rather only for non­navigational situational awareness. Any basemap indication should be compared with other navigation
sources.

WARNING: For safety reasons, GNS 530 operational procedures must be learned on the ground.

WARNING: The United States government operates the Global Positioning System and is solely responsible

for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy and
performance of all GPS equipment. Portions of the Garmin GNS 530 utilize GPS as a precision electronic
NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the GNS 530 can be
misused or misinterpreted and, therefore, become unsafe.

INTRODUCTION

1.3 TAKEOFF TOUR

reading within this Pilot’s Guide includes:

Overview

The Garmin GNS 530 provides the pilot accurate
navigational data and communication capability, along
with non-precision and precision approach certification
in the IFR environment. The takeoff tour is designed to
familiarize the pilot with:

• Powering up the unit

• Changing frequencies

• Entering data

• Performing a simple direct-to

• Selecting IFR procedures

• Using some limited flight plans

In addition, this section briefly covers the Default NAV
Page, the Map Page, and the NAV/COM Page, which are
available as part of the NAV Page Group. These pages are
used for most of the in-flight navigation.

The takeoff tour assumes that the unit and antennas
have been properly installed and that the GNS 530’s
default settings have not been changed. If any of the
factory default settings (position format, units of measure,
selectable fields, etc.) have been changed, the pictures
shown here may not exactly match what is shown on
the GNS 530. Prior to using the GNS 530 for the first
time, Garmin recommends that the aircraft be moved to a
location that is well away from buildings and other aircraft
so the unit can collect satellite data without interruption.

This takeoff tour is intended to provide a brief
introduction of the GNS 530’s major features. Sections
2 through 14 of this manual describe these features and
others in additional detail. Refer to these sections, as
needed to learn or review the details regarding a particular
feature.

Service staff is available during normal business hours
(U.S. Central time zone) at the phone and fax numbers
listed on page ii. Garmin can also be reached by mail
(page ii) or at our website address, www.garmin.com.

Powering up the GNS 530

using the COM Power/Volume knob at the top left
corner of the unit. Turning it clockwise turns unit power
on and increases the COM radio volume. After turning
the unit on, a welcome page is displayed while the unit
performs a self test, followed sequentially by the Unit Type
Page (Figure 1-4) and the Software Version Page. Then
(depending on configuration) the Weather Page, the Traffic
Page, the Aviation Database Page, and the Land/Terrain/
Obstacles Database Page are sequentially displayed.

INTRODUCTION

Satellite Status Page

The Satellite Status Page (Figure 1-10) appears as the

GNS 530 attempts to collect satellite information.

When an ‘Acquiring’ status is displayed on the Satellite
Status Page, the signal strengths of any satellites received
appear as ‘bar graph’ readings. This is a good indication
that the unit is receiving signals and a position fix is being
determined. Following the first-time use of the GNS 530,
the time required for a position fix varies, usually from
one to two minutes.

Figure 1-10 Satellite Status Page

The Satellite Status Page displays a ‘Search Sky’ status, and
the message annunciator (MSG), above the MSG Key also
flashes to alert the pilot of system message, ‘Searching the
Sky’.

Viewing a system message:

Press the

MSG Key (Figure 1-11).

The Message Page appears and displays the status or
warning information applicable to the receiver’s current
operating condition.

Figure 1-11 Message Page

1-8

If the unit can only obtain enough satellites for 2D
navigation (no altitude), the unit uses the altitude provided
by the altitude encoder (if one is connected).

The ‘INTEG’ annunciator (bottom left corner of the
screen) indicates that satellite coverage is insufficient to
pass built-in integrity monitoring tests. In the example
above, not enough satellites are being received to determine
a position. The Satellite Status Page shows the ID numbers
for the satellites and the relative signal strength of each
satellite received (as a bar graph reading).

‘Searching Sky’ indicates that satellite almanac data
is not available or has expired (if the unit hasn’t been
used for six months or more). This means the unit is
acquiring satellite data to establish almanac and satellite
orbit information, which can take five to ten minutes.
The data is recollected from the first available satellite.

Nearest (NRST) Airspace Page

The last page in the NRST group, the Nearest Airspace
Page (Figure 1-29), provides information for up to nine
controlled or special-use airspaces near or in the flight
path. Airspace information appears on this page based on
the same criteria used for airspace alert messages:

• If the projected course will take the aircraft inside
an airspace within the next ten minutes, the
message ‘Airspace ahead -- less than 10 minutes’
appears.

• If the aircraft is within 2 nm of an airspace and the
current course will take it inside of the airspace,
the message ‘Airspace near and ahead’ appears.

• If the aircraft is within 2 nm of an airspace and
the current course will not take it inside of the air
space, the message ‘Near airspace less than 2nm’
appears.

• If the aircraft has entered an airspace, the message
‘Inside airspace’ appears.

-

By default, airspace alert messages are turned off. When
turned on, the message (MSG) annunciator located directly

Flight Plans (FPL)

The GNS 530 lets the pilot create up to 20 flight plans
with up to 31 waypoints in each flight plan. Flight plans
are created, edited, and activated using the FPL Key. The
FPL Page Group includes two pages: the Active Flight Plan
Page and the Flight Plan Catalog Page (Figures 1-31 and
1-32). The Active Flight Plan Page provides information
and editing features for the flight plan currently in use
(referred to as ‘flight plan 00’). The Flight Plan Catalog
Page serves as the main page for creating new flight plans,
as well as editing or activating previously created flight
plans.

Since using flight plans is arguably one of the more
complex features of the GNS 530, it will be discussed only
briefly here, with focus on creating a new flight plan and
activating it to use for navigation. Answers to additional

2.1 COMMUNICATING USING THE GNS 530

The GNS 530 features a digitally-tuned VHF COM radio
that provides a seamless transition from communication
to navigation, bringing the two most important functions
in flying together in one panel-mounted unit. The GNS
530’s COM radio operates in the aviation voice band, from

118.000 to 136.975 MHz, in 25 kHz steps (default). For
European operations, a COM radio configuration to allow
for 8.33 kHz steps is also provided (Section 10.4, Setup
Page: COM Configuration).

Volume

COM radio volume is adjusted using the COM Power/
Volume Knob. Turn the COM Power/Volume Knob

clockwise to increase volume, or counterclockwise to
decrease volume.

Squelch

COM Window and Tuning

Communication frequencies are selected with the
tuning cursor in the standby COM frequency field (Figure

desired frequency. The standby frequency always appears
below the active frequency. The active frequency is
the frequency currently in use for transmit and receive
operations.

The COM radio features an automatic squelch,
providing maximum sensitivity to weaker signals while
rejecting many localized noise sources. The pilot may
wish to override this automatic squelch function when
listening to a distant station or when setting the desired
volume level. The COM Power/Volume Knob allows the
pilot to disable the automatic squelch and keep the COM
audio open continuously.

3.3 DEFAULT NAV PAGE

The first NAV page is the Default NAV Page (Figure
3-4). The Default NAV Page displays a “look ahead” map
display with your present position at the bottom center
of the page. The top of the page displays desired track
(DTK), ground track (TRK), and distance to destination
waypoint (DIS). The bottom of the page indicates ground
speed (GS), active to/from waypoints (only active to, for
a direct-to destination) and estimated time enroute (ETE).
A graphic course deviation indicator (CDI) also appears
at the bottom of the page Unlike the angular limits used
on a mechanical CDI coupled to a VOR or ILS receiver,
full scale limits for this CDI are defined by a GPS-derived
distance (0.3, 1.0, or 5.0 nm), as indicated at both ends of
the CDI. By default, the CDI scale automatically adjusts to
the desired limits based upon the current phase of flight:
oceanic, enroute, terminal area, or approach. The pilot may
also manually select the desired scale setting as outlined in
Section 10.4.

whether the aircraft is heading TO (up arrow) or FROM the
waypoint (down arrow).

Directly above the CDI appears the active leg of the
flight plan, or the direct-to destination when using the
Direct-to Key. This automatically sequences to the next
leg of the flight plan as each interim waypoint is reached.
If no flight plan or direct-to destination has been selected,
the destination field remains blank.

An autozoom feature is available which automatically
adjusts from an enroute range of 2000 nm through
each lower range, stopping at a range of 1.0 nm when
approaching the destination waypoint. The autozoom
feature is turned on/off from the Map Setup Page (described
in Section 3.4).

The Map Page also displays a background map (or
‘basemap’) showing lakes, rivers, coastlines, highways,
railways, and towns. When a map range is selected below
the lower limit at which the map detail was originally
created, an ‘overzoom’ indication appears on the Map
Display, below the range reading (Figure 3-10). The
basemap has limited accuracy, and should not be used
for navigation, but only for non-navigational situational
awareness. Any basemap indication should be compared
against other navigational sources for accuracy. Continuing
to zoom in to lower range settings will cause ‘overzoom’ to
be replaced with ‘no map’ and the geographic detail will
be removed from the Map Display (airport and NAVAID
remain).

Figure 3-10 Overzoom on Map Page

Quickly decluttering the Map Display:

Press the

CLR Key momentarily (as often as

needed) to select the desired amount of map
detail.

The CLR Key allows the pilot to quickly declutter the
Map Display, providing four levels of map detail. Note the
‘-1’ (‘-2’ and ‘-3’ are also provided) suffix designation in
Figure 3-11, indicating each successive declutter level.

Map Detail Level

Figure 3-11 Detail Level on Map Page

Five user-selectable data fields can be added to the
right-hand side of the Map Display. By default, the
displayed data is: destination waypoint name (WPT),
desired track (DTK), ground track (TRK), distance to
destination waypoint (DIS), and ground speed (GS).
Adding these data fields or changing the data types is
outlined in Section 3.4. The five data fields can also be
removed from the map to show a larger map image, as
shown in Figure 3-9.

The ‘Setup Map?’ option (described in Section 3.4)
allows the pilot to define the maximum range at which
each map feature appears. This provides the pilot with
complete control to minimize screen clutter. The pilot
can also quickly remove items from the map using the
CLR Key.

3.8 SATELLITE STATUS PAGE

The Satellite Status Page provides a visual reference
of GPS receiver functions, including current satellite
coverage, GPS receiver status, and position accuracy.
The Satellite Status Page (Figure 3-47) is helpful in
troubleshooting weak (or missing) signal levels due to
poor satellite coverage or installation problems.

As the GPS receiver locks onto satellites, a signal
strength bar appears for each satellite in view, with the
appropriate satellite number (01-32) underneath each
bar. The status of satellite reception is shown as follows:

• No signal strength bars - The receiver is looking
for the satellites indicated.

• Hollow signal strength bars - The receiver has
found the satellite(s) and is collecting data.

• Solid signal strength bars - The receiver has
collected the necessary data and the satellite(s) is
ready for use.

• Checkered signal strength bars - Excluded
satellites.

The sky view display (at top left corner of the page)
shows which satellites are currently in view, and where
they are. The outer circle of the sky view represents the
horizon (with north at top of the page); the inner circle
45° above the horizon; and the center point directly over­head.

Each satellite has a 30-second data transmission that
must be collected (hollow signal strength bar) before the
satellite may be used for navigation (solid signal strength
bar). Once the GPS receiver has determined the present
position, the GNS 530 indicates position, track, and
ground speed on the other navigation pages. The GPS
receiver status field also displays the messages listed in
Table 3-4 under the appropriate conditions:

The Satellite Status Page also indicates the accuracy of the position fix, using Estimated Position Error (EPE), Dilution
of Precision (DOP), and Horizontal Uncertainty Level (HUL) figures. DOP measures satellite geometry quality (i.e.,
number of satellites received and where they are relative to each other) on a scale from one to ten. The lowest numbers
are the best accuracy and the highest numbers are the worst. EPE uses DOP and other factors to calculate a horizontal
position error, in feet or meters. HUL is explained in Section 15.

GPS Receiver Status Messages

Searching Sky The GPS receiver is searching the sky for ANY visible satellites. The

pilot is informed of this status with a ‘Searching the Sky’ message.

Acquiring Sat The GPS receiver is acquiring satellites for navigation. In this mode,

the receiver uses satellite orbital data (collected continuously from
the satellites) and last known position to determine which satellites
should be in view.

2D Navigation The GPS receiver is in 2D navigation mode. Altitude data is provided

by an altitude serializer.

3D Navigation The GPS receiver is in 3D navigation mode and computes altitude

using satellite data.

Poor Coverg The GPS receiver cannot acquire sufficient satellites for navigation.

Rcvr Not Usbl The GPS receiver is unusable due to incorrect initialization or

abnormal satellite conditions. Turn the unit off and on again.

AutoLocate The GPS receiver is looking for any available satellite. This process

can take up to five minutes to determine a position.

flight plan without immediately using it for
navigation guidance. This allows the pilot to
continue navigating the original flight plan, but
keeps the procedure available on the Active
Flight Plan Page for quick activation when
needed.)

6) For precision approaches and some non­precision approaches, a reminder window
appears indicating that GPS guidance on such
approaches is strictly for monitoring only; use
the VLOC receivers and external CDI (or HSI) for
primary navigation. To confirm this reminder,
highlight ‘Yes?’ and press the

ENT Key.

Not all approaches in the database are approved
for GPS use. When selecting an approach, a ‘GPS’
designation to the right of the procedure name (Figure
6-4) indicates the procedure can be flown using the GPS
receiver. Some procedures do not have this designation,
meaning the GPS receiver may be used for supplemental
navigation guidance only. ILS approaches, for example,
must be flown by tuning the VLOC receiver to the proper
frequency and coupling the VLOC receiver to the external
CDI (or HSI).

Once an approach is selected, it may be activated
for navigation from the Procedures Page. Activating the
approach overrides the ‘enroute’ portion of the active
flight plan, proceeding directly to the ‘approach’ portion
(for a full approach, directly to the initial approach fix).
Activating the approach also initiates automatic CDI
scaling transition as the approach progresses.

Activating an approach:

1) Press the

PROC Key to display the Procedures

Page (Figure 6-5).

2) Turn the large right knob to highlight ‘Activate
Approach?’ (Figure 6-5) and press the ENT
Key.

PROCEDURES

Another Procedures Page option allows the pilot to
activate the final course segment of the approach. This
option assumes the pilot will receive vectors to the final
approach fix (FAF) and provides guidance to intercept the
final course, before reaching the FAF.

Activating the approach, with vectors to
final:

1) Press the

PROC Key to display the Procedures

Page.

2) Turn the large right knob to highlight ‘Activate

Vector-To-Final?’ (Figure 6-6) and press the

6.2 NON-PRECISION APPROACH OPERATIONS

The GNS 530 provides non-precision approach
guidance using its built-in GPS receiver. The GPS receiver
can also be used as a supplemental aid for precision
approaches (and for non-precision localizer-based
approaches), but the localizer and glideslope receivers
must be used for primary approach course guidance.

Approaches designed specifically for GPS are often
very simple and don’t require overflying a VOR or NDB.
Many non-precision approaches have ‘GPS overlays’ to
let the pilot fly an existing procedure (VOR, VOR/DME,
NDB, RNAV, etc.) more accurately using GPS.

Many overlay approaches are complex (in comparison
to GPS-only approaches). The GNS 530 displays and
provides guidance through each leg of the approach,
automatically sequencing through each of these legs, up
to the missed approach point (MAP). Approaches may
be flown ‘as published’ with the full transition using any
published feeder route or initial approach fix (IAF), or
may be flown with a vectors-to-final transition.

Figure 6-6 Procedures Page

3) A confirmation window will appear with ‘Yes?’

highlighted, press the ENT Key.

In many cases, it may be easiest to ‘Load’ the full
approach while still some distance away, enroute to the
destination airport. Later, if vectored to final, use the
steps above to select ‘Activate Vector-To-Final’—which
makes the inbound course to the FAF waypoint active.
Otherwise, activate the full approach using the ‘Activate
Approach?’ option.

in the preceding step 3. The GNS 530 provides
both options.

Approaches with Procedure Turns

The procedure turn portion of an approach is stored
as one of the legs of the approach. For this reason, the
GNS 530 requires no special operations from the pilot
(other than flying the procedure turn itself) beyond what
is required for any other type of approach.

Approach operations on the GNS 530 typically begin
with the same basic steps (refer to Figure 6-7 for the
following steps):

1) Select the destination airport using the Direct­to Key, or as the last waypoint in the active

flight plan.

2) Choose the ‘Select Approach?’ option from
the Procedures Page (Section 6.1) or from the
Active Flight Plan Page Menu (Section 5.2,
Active Flight Plan Options).

3) ‘Load’ the approach (often while enroute) in

approach in the active flight plan, but retains
course guidance in the enroute section until
the approach is ‘activated’.

The OBS Key is used to initiate the missed approach,

as follows (refer to Figure 6-22 for the following steps):

1) Press the OBS Key. The missed approach

holding point (MAHP; in this case ‘SWARM’
intersection) is automatically offered as the

NOTE: In some cases, an additional hold

waypoint is added to the missed approach
sequence. This additional waypoint is used
as an aid in establishing the holding pattern,
especially where the MAP and MAHP are the
same waypoint.

2) Follow the missed approach procedures, as
published on the approach plate, for proper
climb and heading instructions. The GNS 530
guides the pilot to the holding pattern, along
the 053° radial from LYH VOR.

3) An alert message in the lower right-hand corner
of the screen recommends entry procedures for
the holding pattern (i.e., ‘HOLD DIRECT’, ‘HOLD

appears on the Default NAV Page. The timer
automatically resets on the outbound side of
the hold when the aircraft is abeam the hold
