Question 1

What is the difference between a green CB and a black CB?

Answer 1

o Green CB’s are monitored by the FWS. If a green CB is out for
more than 1 minute, then an ECAM will be generated.
o Black CB’s are not directly monitored by the FWS. In this case the
component protected by a black CB is monitored directly by the
FWS.

WTB CB’S. We never reset these CB’s.

o On the ground: only reset a CB under the direction of maintenance.

necessary for the safe continuation of the flight. Always allow a 5
minute cooling period and ensure a logbook write-up has been
completed.
