400’RA whichever occurs first.

Warning Systems

• When will the EMER LT unarmed light be illuminated?

• Anytime the switch is out of ARMED

Warning Systems

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

• Yes.

Warning Systems

• What is the required action for STATUS messages prior to departing the gate and

starting engines?

• Contact maintenance for possible corrective action

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

Warning Systems

• What is the effect on warnings/caution/advisory/status messages

with the loss of an EICAS screen?

• Status messages will be inhibited, while other information is compacted onto one

screen.

Warning Systems

• What will cause the activation of the landing configuration warning?

flaps selected.

Warning Systems

the landing configuration?
