Perhaps the ground mapping function in the weather radar?

On the Airbus using the CFDS ground scanning tests various systems and computers, it is like providing the system/computer with known fake inputs via the CFDS test and seeing the system or computer generates the correct outputs or a fault.

Correct! The Ground scan is ti Verify the faults and look for any related Faults. Many Airbus faults might be seen from more than one component.

Hi:
Ground Scanning, for Airbus, is a test were flight conditions are not simulated. It’s simlest test.

Very simple (although I do not remember is this test are available):
Brake # N Ground Scanning, provides brake with hyd pressure for leak check.
A Brake Test, will simulate all conditions during a flight for Brakes, pressure in, antiskid release etc.

Normally, task will indicate which test You must performe, and it depends on previous condition: normal brake wear - ground scanning, wheel with a wear spot: antiskid full test.

Please remember those are just examples, I do not have Manuals with me.

Complete description should be found in front on troubleshooting manual.
(Mechanics don’t use to read this “Introductions”, for neither Boeing nor Airbus Manuals, but I recomend to do it)

The Airbus TSM will give you all the requirements for a Ground Scan. As not every fault reqires a Ground scan to verify it.

Hi: Out of Memory, Ground Scan been the simplest test, is the one You perform most comom, for other tests, like Pitch System, with involve several system, hidraulics, ADIRUS etc, there are specific instructions about when are mandatory.
