Getting Started the First Time
This section explains how to get started using your Apollo GX50. Information in
this section explains how to startup the unit, check signals from the GPS satellites,
enter a seed position, and go Direct-To a destination waypoint.
It is necessary to enter a seed position and the current time the first time you
turn the unit on.
•Power on
•Enter a seed position (your dealer may have already completed this step for you),
if necessary
•Check satellite signal strength
•Enter a “Direct-To,” or destination, waypoint
•Begin navigating
Power On Turn the Power knob clockwise to switch the unit on. The startup screen, testing,
position, and database information shows on the display for several seconds and
then will go into the Navigation function.
Seed
Position
Each time the Apollo GX50 is switched on, it must locate satellites in the sky to
acquire signals before determining a position fix in a complex process involving
lengthy mathematical operations. Without a seed position and the current UTC time
and date, this process can take 10 minutes or more to complete. Enter a Seed Position
to allow the receiver to quickly locate and track available satellites.
Note
The seed position and current time only need to be entered the first
time the receiver is switched on. This information is stored in memory
and need not be entered again. If you move about three hundred miles

Entering a
Seed
Position
After the start up tests, you will always have the choice of entering a Seed
Position. The Seed Position is a starting reference point so the GPS receiver
knows what satellites to look for. If a Seed Position has been previously entered,
you do not need to select a new Present Position or a Reference Waypoint. If you
do not make any selections, the Apollo GX50 will automatically progress into the
Navigation function.

Estimated Time En Route (Ete)
ETE is to the current TO (destination) waypoint from your present position based on the
current ground speed. The units shown are in hours and minutes, 00:00 to 99:59. If the
ground speed is less than or equal to 5 knots, the GPS receiver does not have a valid
position, or there is no TO waypoint, the ETE value will be shown as dashes. If there is
no TO waypoint, the TO identifier location will be replaced by dashes.
Bearing (Brg)
Bearing is the angle from your present position to the TO waypoint. Bearing is shown
from 0 to 359 degrees in one degree increments. Bearing is computed using the magnetic
variation at the Present Position. The Bearing value will be dashed if the FROM or TO
waypoints are blank or the GPS receiver does not have a valid position.
Range (Rge)
The distance from your present position to the TO waypoint. Units can be set as either
nautical miles or kilometers in the Nav Info section of the System functions (see page ).
Nautical mile units are 0.00 to 9.00 nm in 0.01 nm increments, 10.0 to 99.9 nm in 0.1 nm
increments, and 100 to 9999 nm in 1 nm increments. Kilometer units are 0.00 to 99.99
km in 0.01 km increments, 100.0 to 999.9 km in 0.1 km increments, and 1000 to 9999 km
in 1 km increments. The Range value will be dashed if the FROM or TO waypoints are
blank or the GPS receiver does not have a valid position.

may be set to 0.3, 1.0, or 5.0 nm full scale per side. The triangle symbol is also used as a
TO-FROM indicator. When the triangle is facing up, you are on the “TO” side of the
destination waypoint. When the triangle is facing upside down, you are on the “FROM”
side of the destination waypoint.
The number shown on the edge of the display opposite from the triangle symbol shows
the distance off track. The numbered values of Cross Track Error are in the direction you

Minimum Safe Altitude (MSA)
MSA is calculated by taking the Maximum Elevation Figure (MEF) from the sectional
chart grid that corresponds to your current position. In areas below 3,000 feet, 1,000 feet
is added. In areas above 3,000 feet, 2,000 feet is added. In the example below, the current
aircraft would be considered to be at 7,000 feet. If you are within 5 nm of another grid
with a higher MEF, the higher MEF will be used. The MEF on the sectional chart is
derived by taking the altitude of the highest obstruction within the grid, rounded up to the
next 100 feet, and adding 300 feet. For example, if the highest obstruction is 4,728 feet,
the MEF would show as 5,100 feet.

Minimum En Route Safe Altitude (MESA)
Minimum En Route Safe Altitude is the highest MSA for every point between the aircraft
present position and the “TO” waypoint witha5nmbuffer around the course. The value
will be replaced with dashes if there is no valid GPS position, the TO waypoint is blank,
or the current position is outside of the database coverage area. In the example shown
above, the MESA for the present position of the aircraft would be 16,800 ft. The
mountainous terrain would add a 2,000 ft. buffer to the 14,800 ft. Maximum Elevation
figure indicated from the sectional chart.
Flight Time
Flight Time shows the elapsed time in hours and minutes (00:00 to 99:59) from

Nearest
Waypoint
Search
An important safety feature of the GX50 is its ability to locate waypoints closest to your
position. Should you have to land quickly, you can use this feature to locate a nearby
waypoint, assign it as a destination, and quickly navigate to it. Besides the nearest
waypoints to your present position, as an aid in flight planning, you can also select a
reference waypoint from the database and search for waypoints near to it. You can set up
the Nearest Waypoint Search function to filter for certain airport types you select, such
as: runway length, lighting, and surface type. Press INFO while viewing a Nearest
waypoint for more information about that waypoint.
Starting Nearest Waypoint Search
1. Press the NRST key. Turn the Large knob to display the waypoint type and options:
