Satellite Status Page
The Satellite Status Page (the last NAV page) 
provides a visual reference of GPS receiver functions, 
including current satellite coverage, GPS receiver 
status, position accuracy, and displays your present 
position (by default, in latitude and longitude) and 
altitude. The Satellite Status Page also displays the cur
-
rent UTC time at the bottom center of the page. The 
altitude field (ALT) is user-selectable to configure the 
page to your own preferences and current navigation 
needs.

The Satellite Status Page is helpful in troubleshoot-
ing weak (or missing) signal levels due to poor satellite 
coverage or installation problems. You may wish to 
refer to this page occasionally to monitor GPS receiver 
performance and establish a normal pattern for system 
operation. Should problems occur at a later date, you 
may find it helpful to have an established baseline 
from which to compare.  As the GPS receiver locks onto satellites, a signal 
strength bar appears for each satellite in view, with the 
appropriate satellite number (01-32, WAAS satel
-
lites will have higher numbers) underneath each bar. 
The progress of satellite acquisition is shown in three 
stages: 
• No signal strength bars — the receiver is looking 
for the satellites indicated. 
When the 500W-series unit is first powered 
on, an “Acquiring” status appears at the top  of the page and no signal strength bars are  displayed. 
•  Hollow signal strength bars — the receiver has 
found the satellite(s) and is collecting data. 
•   Cross-hatch cyan signal strength bars — the 
receiver has found the satellite(s) but it has been 
excluded by the FDE program as a faulty satellite. 
•   Solid cyan signal strength bars — the receiver has 
collected the necessary data, but is not using the 
satellite in the position solution. 
•   Solid green signal strength bars — the receiver 
has collected the necessary data and the satellite is 
being used in the position solution. 
The “D” character inside the bars indicates differ-
ential corrections (e.g. WAAS) are being used for that 
satellite. 
The Time and other data may not be displayed 
until the unit has acquired enough satellites for a fix.

Satellite Status Page
As satellites are received, the status changes to “3D Navigation”. 3D Navigation includes  altitude. 
The sky view display at the top left corner of the 
page shows the satellites currently in view as well as 
their respective positions. The outer circle of the sky 
view represents the horizon (with north at the top 
of the circle); the inner circle represents 45° above 
the horizon and the center point shows the position 
directly overhead. 
To change the user-selectable data field: 
1.  Press  MENU to display the Satellite Status Page 
Options menu. 
2.   Turn the large right knob to highlight 
“Change Fields?” and press ENT. 
By default, current altitude (ALT) is displayed 
in the lower right corner of the page. This field is user selectable using the “Change  Fields?” option. 
3.  Turn the small right knob to display the list 
of available data items. Continue turning the 
small right knob to select the desired data 
item from the list.

 NOTE: Do not rely solely on MSA as an absolute measure of safe altitude. Consult current charts and NOTAMs for your area. 
4.  Press  ENT to select the desired data item and 
return to the position page. 
5.   Press the small right knob momentarily to 
remove the cursor from the page.

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 deter
-
mined your position, the 500W-series unit indicates 
your position, altitude, track and ground speed. The 
GPS receiver status field also displays the following 
messages under the appropriate conditions: 
• Searching Sky —
 
The GPS receiver is searching the sky for ANY vis-
ible satellites. You are also informed of this status 
with a “Searching the Sky” message. 
• Acquiring Sat — 
 
The GPS receiver is acquiring satellites for naviga-
tion. In this mode, the receiver uses satellite orbital 
data (collected continuously from the satellites) and 
last known position to determine the satellites that 
should be in view. 
• 3D Navigation — 
 
The GPS receiver is in 3D navigation mode and 
computes altitude using satellite data. 
• 3D Differential Navigation— The GPS receiver is  in 3D navigation mode and differential corrections 
are being used. 
The Satellite Status Page also indicates the accu
-
racy of the position fix, using Horizontal Figure of 
Merit (HFOM), Vertical Figure of Merit (VFOM), and 
Estimated Position Uncertainty (EPU). HFOM and 
VFOM represent the 95% confidence levels in hori
-
zontal and vertical accuracy. The lowest numbers are 
the best accuracy and the highest numbers are worse. 
EPU is the horizontal position error estimated by the 
Fault Detection and Exclusion (FDE) algorithm, in feet 
or meters. 
 NOTE  Operating outside of an SBAS service area 
with SBAS enabled may cause elevated EPU values to  be displayed on the satellite status page.  Regardless of the EPU value displayed, the INTEG annunciation is the controlling indication for determining the integrity of the GPS navigation solution.

Dead Reckoning
Dead Reckoning
Dead reckoning is the process of continuing navi-
gation using your last known position and speed after 
a loss of GPS navigation while on an active flight plan. 
 CAUTION: Navigation using dead reckoning is there-
fore only an estimate and should not be used as the sole means of navigation. Use other means of naviga
-
tion, if possible. 
Dead reckoning becomes active after a loss of GPS 
position while you are navigating using an active flight 
plan. 
A pop-up message will appear and you must clear 
the message before continuing operation. 
The ownship icon color is changed to yellow. The To/
From flag is removed from the CDI. The Dead Reckon
-
ing annunciator (DR) appears on the left side of the 
map display when GPS position is unavailable and the 
unit is in Dead Reckoning mode. All external outputs 
dependent on GPS position are flagged. 
Terrain will be noted as not available and new terrain 
advisory pop-ops will not occur. Traffic and Storm
-
scope information will not be shown on the Map page, 
but will continue to be available on their own dedi
-
cated pages. XM or FIS-B weather will still be available 
on the Map page.  Dead Reckoning mode will continue until GPS posi
-
tion is restored, when GPS navigation is restored Dead 
Reckoning mode is exited. The DR annunciations 
will be removed and GPS information will be used to 
compute navigation related information for the current 
flight phase. 
Dead Reckoning is only allowed in En Route and 
Oceanic flight modes. If the unit is in a Terminal or 
Approach flight mode when Dead Reckoning takes 
place, “No GPS Position” will be displayed on the map 
pages and all navigation data will be dashed. If you are 
operating in Dead Reckoning mode and a transition to 
Terminal or Approach flight modes would occur from 
the projected Dead Reckoning position, Dead Reckon
-
ing mode will be discontinued. “No GPS Position” will 
be displayed on the map pages and all navigation data 
will be dashed.

Section 3   
Direct-To Navigation
The direct-to function provides a quick method 
of setting a course to a waypoint. Once a direct-to is 
activated, the unit establishes a point-to-point course 
line (geodesic path) from your present position to the 
selected direct-to waypoint. The unit will provide navi
-
gation guidance to the selected direct-to waypoint until 
the direct-to is manually cancelled or replaced by a new 
active leg or direct-to. 
To select a direct-to waypoint: 
1.   Press the direct-to key. The Select Direct-to 
Waypoint Page appears, with the waypoint 
identifier field highlighted. 
Pressing the direct-to key displays the Select   
Direct-to Waypoint  Page. 
2.   Use the small  and large right  knobs to 
enter the identifier of the desired direct-to 
waypoint. 
Use the small and large right knobs to enter 
the name of the direct-to waypoint. Press ENT  once the name has been fully entered. 
3. Press  ENT to confirm the selected waypoint 
and  ENT (again) to activate the direct-to func-
tion. 
If you’re navigating to a waypoint and get off 
course, the direct-to function may also be used to re-
center the CDI (HSI) needle and proceed direct-to the 
active waypoint. 
To re-center the CDI (HSI) needle to the active 
waypoint: 
1.   Press the direct-to key, followed by ENT  
twice. 
 NOTE: When navigating an approach with the  missed approach point (MAP) as the active way
-
point, re-centering the CDI (HSI) needle with the direct-to key cancels the approach.
