TRIPPED C/B REENGAGEMENT
Applicable to: ALL
In flight, do not reengage a circuit breaker (C/B) that has tripped by itself, unless the Captain judges it
necessary to do so for the safe continuation of the flight. This procedure should be adopted only as a
last resort, and only one reengagement should be attempted.
On ground, do not reengage the C/B of the fuel pump(s) of any tank. For all other C/Bs, if the flight
crew coordinates the action with maintenance, the flight crew may reengage a tripped C/B, provided
that the cause of the tripped C/B is identified.
COMPUTER RESET
Applicable to: ALL
COMPUTER RESET
The normal purpose of a circuit breaker (C/B) is to protect wiring against short circuits, and to
isolate equipment for maintenance.
Another C/B function involves digital computers: The reset function. When a digital computer
behaves abnormally due to an electrical transient, for example, the abnormal behavior can be
stopped by briefly interrupting the power supply to its processor.
The flight crew can reset most of this aircraft’s computers with a normal cockpit control (selector
or pushbutton). However, for some systems, the only way to cut off electrical power is to pull the
associated C/B.
To perform a computer reset:
Set the related normal cockpit control to OFF, or pull the corresponding ‐ reset pushbutton or circuit
breaker
‐ Wait 3 s if a normal cockpit control is used, or 5 s if a circuit breaker is used (unless a different
