Inhibit Checklist Line Items
When a single airplane system failure results in the display of multiple EICAS
alert messages (a primary message and one or more consequential messages),
inhibit checklist line items allow unnecessary non-normal checklists
(consequential checklists) to be inhibited from display in the checklist queue.
Consequential EICAS alert messages may be displayed as a result of a primary
failure condition. For example, an AUTO SPEEDBRAKE message is displayed
as a result of a HYD PRESS SYS C condition. Consequential EICAS alert
messages also may result from a non-normal checklist crew action. For example,
a PACK L message is displayed when the crew selects the pack off during
accomplishment of the SMOKE AIR CONDITIONING checklist. Corresponding
consequential checklists are inhibited by inhibit checklist line items in the primary
checklist. The inhibit checklist line item lists the consequential checklists which
are inhibited. The inhibit has the following effects on a consequential checklist:
• checklist icon is removed from corresponding EICAS message
• checklist is removed from checklist queue
• notes are not collected on operational notes page
• deferred items are not collected in normal checklists
If consequential checklist steps, notes, and information are applicable to the
primary failure condition, then these are included in the primary checklist.
Additional Information
Additional information is provided for some checklists. It is located at the very
end of the associated non-normal checklist. Viewing the information is not
required to complete the checklist.
Precautionary Text
Precautionary text is critical information which should be read before completing
certain non-normal checklist actions. Precautionary text is displayed directly
above the associated line item.
Timers
Where required, an automatic timer is displayed in the upper right hand corner of
the checklist page. Timers help the flight crew keep track of time delays that are
part of checklists. All timers are countdown timers. Timers can be associated with
open loop, closed loop, or conditional line items.
