Sound judgment as well as thorough knowledge of the aircraft, its charac-
teristics, and the flight manual procedures are essential in the handling of
any abnormal system and/or flight condition. In addition to the outlined
items in the Abnormal Procedures, the following steps are considered part
of all abnormal situations:
•
Maintain Aircraft Control
•
Analyze the Situation
•
Take Appropriate Action
Circuit Breakers
Some procedures involve manipulating circuit breakers (CBs). The
following criteria should be followed during “Circuit Breaker” steps:
•
Intentional pulling of circuit breakers during flight, other than as
required in specific procedures, is prohibited.
•
When instructed to “SET”, the appropriate circuit breaker should be
checked for normal condition. If the circuit breaker is not “SET”, it
may be reset only once. If the circuit breaker opens again, do not reset.
•
When instructed to “PULL”, the appropriate circuit breaker should
only be pulled and not reset.
•
When instructed to “CYCLE”, the appropriate circuit breaker should
be pulled, delayed for several seconds, and reset only once. Allow suffi-
cient cooling time for circuit breakers that are reset through a
“CYCLE” procedure.
Procedure Division Symbols
For procedures requiring pilot decision, conditional steps are indented
with a symbol to designate sub-sections within the procedure. On condi-
tion, the pilot makes a decision to identify the applicable sub-section.
Following the initial decision, a further sub-division of the procedure may
occur. In that event, one or more additional conditions guides the pilot
through the remaining decisions. Once the applicable condition(s) are
identified, the pilot follows the remaining steps until the indication "Proce-
dure Complete" is reached.
The procedure symbol levels are:
