CI.2 Checklist Introduction-Non-Normal Checklists
Introduction
This chapter contains checklists used by the flight crew to cope with non-normal
situations. The checklists are grouped in logical sections which match the system
description chapter arrangement in Volume 2. The checklists are arranged in
alphabetical order within in each section.
Checklists without a visible cue (such as DITCHING) are called unannunciated
checklists.
All unannunciated checklists are found in the first section of the Non-Normal
checklists chapter. Some unannunciated checklists also appear in an associated
systems section (such as INFLIGHT ENGINE START in the Engines, APU
section.)
A condition statement is provided for all non-normal procedures.
Checklists may contain both recall and reference items. Recall items are critical
steps that must be accomplished from memory. Reference items are actions to be
accomplished while reading the checklist. In the Table of Contents for each
non-normal checklist section, the titles of checklists containing memory items are
printed in bold type.
Certain amplified information is included in brackets [ ] when the reason for the
task may not be self-evident. These items are printed in normal font characters and
are not bold.
Non-Normal Checklist Operation
Non-normal checklists begin with steps to correct the situation or condition.
Information for planning the remainder of the flight is included. When special
tasks are required to configure the airplane for landing, the tasks are included as
part of the non-normal checklist. Flight patterns for certain non-normal situations
are located in Non-Normal Maneuvers chapter, and show the sequence of
configuration changes.
While every attempt is made to establish necessary non-normal checklists, it is not
possible to develop checklists for all conceivable situations, especially those
involving multiple failures. In certain unrelated multiple failure situations, the
flight crew may have to combine elements of more than one checklist and/or
exercise judgment to determine the safest course of action. The captain must
assess the situation and use sound judgment to determine the safest course of
action.
