-Non-pilot selected automatic activation of certain critical systems (L or R FUEL PUMP ON) -Loss of system redundancy -Needed information not related to a change of system status (SELCAL) -May have a tone associated (i.e. cabin call or voice SELCAL) STATUS (S) MESSAGES White status messages appear directly below any advisory messages that may be present. White status messages: -Indicate the state of a specific system that has been manually activated INHIBITED EICAS MESSAGES Takeoff and landing are the most critical phases of flight, and the most workload intensive. Accidents can occur during these phases of flight due to the crew becoming distracted by minor non-relevant system problems. To reduce the possibility of this occurring, some warning messages, most caution messages, and all advisory messages are inhibited during the take-off and landing phase. Selected messages are inhibited for takeoff when airspeed is above 80 kts, and the aircraft reaches 400 ft AGL. Selected messages are inhibited during landing when the aircraft descends below 400 ft AGL and airspeed decreases to less than 40 kts. Inhibited messages are indicated with a X in the respective column. When a message is triggered during an inhibit period, the message and the master/caution (if appropriate) illuminates as the aircraft exits the inhibit envelope. SYNOPTIC PAGES The synoptic pages can be selected for presentation on the bottom half of either MFD by using the individual switches lo-cated on the MCP control panel. The synoptic pages provide the pilot real-time indication of aircraft system operation. Each synoptic page displays the aircraft systems as a schematic diagram. ANTI-ICE The anti-ice synoptic page displays the operation of the following systems: -Bleed air system -Wing anti-ice system -Engine anti-ice system ECS The ECS synoptic page displays information for the following systems: -Bleed air -Air conditioning -Pressurization ELECTRICAL The electrical synoptic page displays the system using a block diagram. FLIGHT CONTROLS The flight control synoptic page displays the positions of the ailerons, elevator, rudder and spoilers.
