d) Power removed and then reapplied to both left and right EICAS computers.
3) An Engine Shutdown inhibit is in effect when the fuel control switch is in the CUTOFF position or when the engine fire switch is pulled. The level B L or R ENG SHUTDOWN EICAS message will show. All other currently existing level B (except for level B L STARTER CUTOUT, R STARTER CUTOUT) and level C messages are removed from display. If a new level C message is generated during this inhibit period, they are not displayed.
4) This Engine Shutdown inhibit is removed in one of the following ways: a) When the starter cutout condition no longer exists or
the respective fuel control switch is shut off, b) When a new level B message has been generated, c) When 20 seconds have elapsed since initiation. d) Pushing the CANCEL/RECALL SWITCH on the P1-3 panel.
(h) Message Paging and Overflow 1) Each category of messages has multiple paging capability. Up to eleven messages will be displayed in each list. If more than eleven messages exist, only ten will be displayed. The bottom message will be replaced by a page indicator. The additional messages can be accessed by incrementing to the next page. A different control is used for each list to increment to the next page. 2) Alert messages are cycled using the CANCEL and RECALL switches. Pressing CANCEL will remove all level B and level C messages presently diplayed and cause subsequent level B and C messages to be displayed. Level A messages are unaffected. If a new message is generated after all current B and C messages are cleared, it will still be automatically displayed. Pressing RECALL will return the message list to page 1. The word RECALL will momentarily be displayed on the bottom line of the list. 3) Status messages are cycled using the STATUS switch. Once the status page is selected, subsequent presses of STATUS will display additional pages of status messages. The PAGE readout will also be incremented. Pressing STATUS once more after all messages have been cycled will clear the status page from the display.
4) Maintenance messages are cycled using the ECS/MSG switch. Once the ECS/MSG page is selected, subsequent presses of the ECS/MSG switch will display additional pages of maintenance messages. The PAGE readout will also be incremented. Pressing ECS/MSG after all messages have been cycled will clear the ECS/MSG page and display the secondary engine page.
