A
i.
VLOC STATUS (ROM, XILINX, SYN LOCK, EEPROM)
―
displays condition of various
NAV receiver components. These boxes should be green, a red box indicates an internal
failure.
MAIN STATUS:
a.
ROM, FPGA 1/3, EEPROM 1/2
―
displays the condition of various GIA 63/GIA 63W main
board components. These boxes should be green, a red box indicates an internal failure.
b.
+5, +3.3, -5, +12/-12, +28 PWR RANGE
―
displays condition of various internal power
supply ranges. They need to be within 10% of desired voltages. Replace the unit if these
values are more than 10% from the desired voltage.
c.
AIRCRFT PWR A/B RNG
―
displays the technician that the main power inputs of the GIA
63/GIA 63W are within acceptable ranges. If a box is red, and the Aircraft PWR voltage is
listed as 0 in the Analog Status box below, check that all aircraft buses are on and GIA
breakers are pushed in.
d.
ANALOG CAL
―
displays the condition of the GIA calibration. (Green = Valid Analog
Calibration)
e.
OVER TEMP
―
informs the technician of an over-temperature condition on the GIA 63/GIA
63W main board. (Red = Over-temperature, Green = Normal-temperature)
f.
LOW TEMP
―
informs the technician of a low temperature condition on the main board.
(Red = Low-temperature, Green = Normal-temperature)
g.
BKUP CAPS
―
i
ndicates status of the Backup Capacitor Test. A green box indicates the test
passed, a red box indicates it failed.
ANALOG STATUS:
a.
AIRCRFT PWR (A, B)
―
displays aircraft power input values, expressed in Volts DC
(example: 2214 = 22.14 Vdc).
b.
TEMPERATURE
―
displays the internal temperature of GIA unit, expressed in degrees
Fahrenheit (example: 12267 = 122.67°F).
c.
DISCRETE:
d.
SYS ID PROG 1, 2
―
identifies the assigned GIA number when two or more GIA units are
installed. Green indicates that the System ID pin is left strapped to ground. Black indicates
that the System ID pin is left ‘open’ and not strapped to ground. GIA #3 and GIA #4 may
not be used in certain VLJ aircraft.
GIA System ID 1
GIA System ID 2
GIA Unit Number
Black Black #1
GIA
Green Black #2
GIA
Black Green #3
GIA
Green Green #4
GIA
e.
FUEL
―
displays the type of fuel to be used on the aircraft.
