Preparing for a Flight
Prior to flight, the flight crew must prepare a flight log to document the upcoming
flight. The ELB flight preparation function offers an electronic version of a
pre-flight process to assess the technical status of an airplane. This is an ELB
guided process intended to be used prior to flight. The sequence of tasks includes:
• reviewing all open items
• reviewing all deferred items
• reviewing the fault history
• creating a new flight log
• reviewing the maintenance release (if available)
Completing the flight preparation process creates an inactive flight log. Only
when a flight log is active can a fault be recorded. The flight log is activated
automatically when the groundspeed exceeds 3 knots, or when the weight on
wheels indicator becomes false. The flight log can also be manually activated by
selecting ACTIVATE from the FLIGHT LOG menu.
Reviewing Open Items
To begin the flight preparation process, select FLIGHT PREPARATION from the
Logbook Home page to display the Open Items page. The system performs a
search of the onboard database and looks for fault reports with the status of Open.
The list also includes any expired deferrals. If the maintenance release has already
been signed, no open items are displayed on this page. If the maintenance release
has not been signed, faults that have not yet been deferred or closed by the
maintenance crew are displayed.
If the Open Items page lists any faults, they must be closed or deferred by the
maintenance crew before the flight can begin. However, even if there are open
faults, continue with flight preparation by selecting DEFERRED ITEMS at the
bottom right of the page.
Note: The maintenance release for the aircraft is not visible if there are open
items. These must be closed by maintenance prior to flight.
Note: The ELB flight preparation function is designed so that the next step in the
process can be selected using the soft key at the bottom right of each page.
Reviewing Deferred Items
The Deferred Items page allows for review of the airplane’s deferred items
(sometimes called "open deferrals" or "active deferrals"). The user can select the
item from the list to review the item further. Information for each fault includes
the description and the date on which the deferral expires. Select DEFERRED
ITEMS to go back to the Deferred Items page. After reviewing the deferred items,
select FAULT HISTORY.
