Which display unit shows the engine parameters and provides abnormal and emergency checklists?

The Upper Display Unit (UDU) is responsible for displaying crucial engine parameters, which include readings like engine thrust, temperatures, and pressures. This display allows the flight crew to monitor engine performance effectively throughout the flight. In addition to showing real-time parameters, the Upper Display Unit also provides access to abnormal and emergency checklists. These checklists are critical for flight safety, allowing pilots to respond appropriately to various in-flight situations.

The design of the A320 flight deck incorporates multiple display units, each serving specific functions. While the Lower Display Unit primarily focuses on systems page displays, the Flight Control Unit is dedicated to manual flight control inputs, and the Standby Flight Instruments provide backup data in the event of a primary systems failure. Their functionalities are distinct and do not encompass the comprehensive engine parameter and emergency checklist roles that the Upper Display Unit fulfills.
