HECKOUT
Switch on the GX50/60/65 in the normal mode to complete this part of the checkout. The
GX50/60/65 will go through a sequence of self tests.
The GX50/60/65 requires a “seed” position, time, and date for the GPS sensor to know which
satellites to look for. Once this is entered, it will be saved and updated automatically. If the
GX50/60/65 is moved a great distance without being turned on, the seed position may have to
be re-entered.
Entering the seed position:
1.
During the display startup sequence, press
SEL
when the position page is displayed.
2.
Rotate the
LARGE
knob to move the cursor to different fields, rotate the
SMALL
knob to
input the correct lat/lon, and then press
ENT
to save the changes.
The seed position can also be input with reference to a waypoint. Refer to the user’s manual
for instructions.
Entering the time and date:
The time and data can be entered after the power up sequence from the nav page display.
1.
Press the
SYS
button, rotate the
LARGE
knob to display the “S
YSTEM
I
NFO
” page, and
press
ENTER
.
2.
Press
SEL
, rotate the
LARGE
knob to move the cursor to different fields, rotate the
SMALL

GPS Operation and Position
This checkout is to be completed with the aircraft moved away from hangars and other
structures that may obstruct the view of the satellites.
1.
Turn on the GX50/60/65 and allow the unit to acquire a position. All other avionics
should be turned off for this part of the test.
2.
Check the position using the lat/lon navigation page. Press the
NAV
button and rotate the
LARGE
knob to the lat/lon page. The lat/lon should agree with a known reference position.
3.
Check the signal reception using the GPS sensor displays in the System mode. Press the
SYS
button, rotate the
LARGE
knob to the “GPS S
ENSOR
:” page, and press
ENT
. Then
rotate the
SMALL
knob to display the GPS info. Typical signal levels are 50 or better.
4.
Turn on other avionics one at a time and check the GPS signal reception to make sure it
is not affected.
5.
Check for VHF comm transmitter interference. This must be completed on all IFR
installations.
a)
Verify that 5 to 8 satellites are in DATA and the NAV flag is out of view.
b)
Tune the comm to 121.150 MHz and transmit for 20 seconds.
c)
Verify that the position is not lost.
