Description

The SD screen has three horizontal sections:

  • The top section provides the system display page, the STATUS page, or the STATUS MORE page. In normal operation, the SD provides system display pages. The system display pages appear:
    • Automatically, depending on the flight phase. For more details Refer to Normal Operation, or
    • When manually-selected by the flight crew. For more details refer to ECP.
  • The middle section displays permanently-displayed data such as: External temperature, time, aircraft weight, CG, and Fuel On Board (FOB).
  • The bottom section displays the mailbox (Refer to ECP).

In addition, after an alert due to a system failure, the SD displays:

  • The applicable system display page, if any.
  • The aircraft STATUS page after the flight crew clears the alert from the EWD, if the STATUS page is not empty.

  • SD page that the flight crew manually selects.
