• Inhibited takeoff roll at 80knots to 20 seconds
  after nose strut extension or 400RA whichever
  occurs first.

38
Warning Systems

• Anytime the switch is out of ARMED

39
Warning Systems

• Will the EMER lights come on with loss of Normal
  DC?
• Yes.

40
Warning Systems

• What is the required action for STATUS messages
  prior to departing the gate and starting engines?
• Contact maintenance for possible corrective action

41
Warning Systems

• What does the takeoff configuration warning test?
• Slat/flap takeoff configuration, stabilizer trim
  out of green band, spoilers armed, and/or,
  parking brake set

42
Warning Systems

• What is the effect on warnings/caution/advisory/st
  atus messages with the loss of an EICAS screen?
• Status messages will be inhibited, while other
  information is compacted onto one screen.

43
Warning Systems

• What will cause the activation of the landing
  configuration warning?
• When below 800 and the gear not down and the
  throttles are retarded, or landing flaps selected.

44
Warning Systems

Warning Systems

• Below 800RA

46
Warning Systems

48
Warning Systems

• During flight what causes the slats to
  automatically extend to the landing
  configuration?
• A stall warning causes the slats to extend to the
  landing position if the slats are in the Takeoff
  position. When the stall no longer exists the
  slats automatically retract.

49
Warning Systems

  proximity system?

  vertically sheer terrain or of slow descents into
  unprepared terrain while in the landing
  configuration?
• No.

53
Warning Systems

• When is the predictive wind shear alert
  inhibited?
• Yes, during takeoff at airspeeds above 100kts,
  until reaching 50AGL.
