External inputs diagnostic
The external digital inputs diagnostic screen shows if the IDENT and standby modes are active
or inactive. It also shows if the squat switch is indicating that the aircraft is ground, airborne, or
unknown. You can use this screen to verify that the squat switch settings are properly
configured.
Analog inputs diagnostic
The analog inputs diagnostic screen shows the current reading of the lighting bus and ambient
light sensor to the nearest percentage, and the current reading of the internal temperature
sensor to the nearest degree Celsius.
GPS receiver diagnostic
The GPS receiver diagnostic screen shows the current reading of the GPS latitude, GPS
longitude, and Navigation Integrity Category (NIC).
GPS CN0 diagnostic (Stratus ESG only)
The GPS CN0 diagnostic screen shows the current value of GPS CN0 for all 12 channels.
Software versions diagnostic
The software versions diagnostic screen shows the DSC part number, version number, and
flash checksum.
Complex hardware versions diagnostic
The complex hardware versions diagnostic screen shows the FPGA part number, version
number, and flash checksum.
BIT diagnostic
The BIT diagnostic screen displays any Built In Test failure codes. If the screen displays all
zeros, no BIT failure has been detected. Otherwise, a “1” will display.
Each number corresponds with a specific failure, depending on its position in the string of
numbers on the screen—failure position 1 being the leftmost space, and failure position 20
being the rightmost space. Reference the table below to determine which BIT has failed. Once
all BIT failures have been resolved, press
ENT
to clear all codes.
NOTE:
The following BIT failure positions are applicable to software (DSC) version R07. For
version R06, the first 2 BITs are not present. For earlier versions, the first 3 BITs are not
present.
