10-74 The display select panel allows the pilot to choose which  computer is actively supplying information. It also controls  the display of secondary engine information and system status  displays on the lower monitor. EICAS has a unique feature  that automatically records the parameters of a failure event  to be regarded afterwards by maintenance personnel. Pilots  that suspect a problem may be occurring during flight can  press the event record button on the display select panel. This  The highest level of automated flight system is the flight FMS.  Companies flying aircraft for hire have special results they  wish to achieve. On-time performance, fuel conservation, and  EICAS uses BITE for systems and components. A  maintenance panel is included for technicians. From this  panel, when the aircraft is on the ground, push-button  switches display information pertinent to various systems  for analysis.  [Figure 10-125] also records the parameters for that flight period to be studied  later by maintenance. Hydraulic, electrical, environmental,  performance, and APU data are examples of what may be  recorded. EICAS provides full time primary engine parameters (EPR,  N$_{1}$, EGT) on the top, primary monitor. Advisories and  warning are also shown there. Secondary engine parameters  and nonengine system status are displayed on the bottom  screen. The lower screen is also used for maintenance  diagnosis when the aircraft is on the ground. Color coding  is used, as well as message prioritizing.  Figure 10-122.  Nine of the 12 available system diagrams from the ECAM manual mode.
