A non–normal checklist containing deferred items is considered complete when
all applicable steps prior to the deferred items have been accomplished. The
CHECKLIST COMPLETE EXCEPT DEFERRED ITEMS indicator is displayed
at the bottom of the page.
If a non–normal condition occurs after completion of the approach or landing
checklist, the originating non–normal checklist is considered incomplete until all
steps including the deferred items are accomplished.
Conditional Line Items
There are two types of conditional line items within checklists:
• closed loop (airplane system state sensed)
• open loop (airplane system state not sensed)
Open loop conditional line items are followed by selections labeled YES and NO.
The cursor is placed adjacent to the YES – NO line, requiring the pilot to use the
cursor to select the appropriate answer.
If the pilot selects YES, the steps associated with the conditional line item become
active. If the pilot selects NO, the steps associated with the conditional line item
become inactive and change color to cyan indicating the steps are not applicable.
The current line item box skips past the cyan items. Cyan steps are not selectable.
Any associated operational notes are removed from the notes page and deferred
line items are removed from the target normal checklist when they are displayed
in cyan. YES-NO selections remain active even after a selection is made. The pilot
can change selections at any time.
Sometimes a group of two or more open-loop conditional line items are designated
as a mutually exclusive set. When the pilot answers YES to any one of the items
in the exclusive set, all other items are automatically answered NO. However, the
opposite is not true. If all of the items but one are answered NO, the last item is
not automatically answered YES. The pilot must manually select YES to one of
the conditional line items in the exclusive set.
The closed loop conditional line item function is identical to open loop except the
decision is made automatically by using airplane system state sensing. When the
conditional line item is sensed true, it changes color to green and the current line
item box moves to the first incomplete step associated with it. If the condition is
sensed false, the conditional line item and its associated steps are no longer
applicable and change color to cyan. The current line item box skips past the cyan
items.
