Dual Database
The dual database feature provides the flight crew the capability of activating
either of two different ECL databases, each having a different database part
number and revision identification. Revision identification usually corresponds to
the Operations Manual revision or an effective date for the new database.
Selection of a different ECL database is accomplished on the RESET menu using
the CCD. Database selection keys are used to activate the desired database. A
green diamond displayed in the active database indicator shows the active
database. The flight crew can select either ECL database as often as desired while
on the ground. The database selection keys are inhibited in flight. Changing the
active ECL database also results in RESET ALL action.
Checklist Access
Air/ground logic, fuel control switch position, and EICAS message level
determine the checklist retrieval priority when the checklist display switch is
pushed.
Checklist call–up priority order is shown below.
On the ground with both fuel control switches in the CUTOFF position and both
engine start selectors in NORM:
• checklists associated with any EICAS warning messages
• NORMAL checklists (incomplete or not yet displayed)
• checklists associated with any EICAS caution messages
• checklists associated with any EICAS advisory messages
• unannunciated (no EICAS message) checklists
On the ground with either fuel control switch in the RUN position, or either engine
start selector not in NORM, or in the air:
• checklists associated with any EICAS warning messages
• checklists associated with any EICAS caution messages
• checklists associated with any EICAS advisory messages
• unannunciated checklists
• NORMAL checklists
Normal Checklists
Normal electronic checklist use follows the same philosophy as used with paper
checklists. The normal procedures are done from memory, then the checklist is
read to confirm the actions.
