Level D
:
Software whose anomalous behavior, as shown by the system safety assessment process,
would cause or contribute to a failure of system function resulting in a minor failure condition
for the aircraft.

5.10. Logic of on-Ground interface
The transponder has an on-ground interface, which should be connected to your aircraft installation, if
an adequate signal will be provided. The following table shows the system behaviour for different
configurations and input at the interface
