General
This chapter contains procedures (adverse weather operation, engine crossbleed
start, and so on) accomplished as required rather than routinely performed on each
flight. Systems tests are described in the System Description chapter of the
applicable system.
Note: System tests are not normally a flight crew action.
Procedures accomplished in flight, or those that are an alternate means of
accomplishing normal procedures (such as manual engine start), are usually
accomplished by recall. Infrequently used procedures, not normally accomplished
(such as engine crossbleed start) are usually accomplished by reference.
Supplementary procedures are provided by section. Section titles correspond to
the related chapter title for the system being addressed except for the Adverse
Weather section.
