as green text with a complete indicator (green check mark) to the left. Overridden
and inactive line items are displayed in cyan.
Closed Loop Line Items
Closed loop line items are steps in the checklist that involve the continuous and
automatic monitoring of switch, lever, or selector position. In a limited number of
cases, actual system state, such as flap or landing gear position, is monitored.
When the control is in the required position, the line item text color changes from
white to green. In addition, a complete indicator is displayed left of the line item.
The current line item box then moves to the next line item to be completed.

Open Loop Line Items
Open loop line items are steps in the checklist that require the flight crew to
manually confirm completion by using the CCD cursor select switch. Open loop
line items do not provide any monitoring of control position or system state. Open
loop line items rely on the flight crew to confirm that the required action has been
completed, or that a specific condition exists. Open loop line items can be
distinguished from closed loop line items by display of the open loop indicator, a
gray box located to the left of the line item. When the cursor is positioned within
the current line item box or open loop indicator, and the CCD cursor select switch
is pressed, the checklist line item text color changes from white to green and a
complete indicator is displayed on the open loop indicator. The current line item
box then moves to the next line item to be completed.
Operational Notes
Checklist operational notes are used for ongoing consequences of the non-normal
condition, such as:
• inoperative equipment lists
• operational limitations
Operational notes are selectable through the operational notes key at the bottom
of the page. After display of a non–normal checklist that includes operational
notes, the notes are accessible during all subsequent phases of flight. Each
operational note includes a checklist reference for the checklist that generated the
note.
If there are multiple pages of operational notes, page keys are displayed. Once all
pages of operational notes have been accessed, the cursor is placed on the
non–normal checklist key, if it is displayed, or moves to the normal checklist key.
Operational notes are dependent upon the status of the non–normal condition
causing the note. If the condition goes away, the checklist reference and associated
notes are removed from the operational notes display.
Deferred Line Items
Deferred line items are items that are part of a non-normal checklist, but must be
accomplished later in the flight, usually during approach.
If a non–normal checklist containing deferred items is displayed, the items are
automatically attached to the appropriate normal checklist. Each set of deferred
items is referenced to the checklist that generated the deferred item. Any type of
line item can be a deferred item.
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
