[单选题]Which of the following is correct about continuous ignition?
A. Continuous ignition is selected automatically when the ENG ANTIICE pb-sw or approach idle is selected.
B. Continuous ignition will also be engaged if max takeoff thrust (EPR or rated N1 mode) or FLEX takeoff thrust (EPR mode) is selected, or when EIU data (ignition or bleed configuration information)is not available.

[单选题]which of the following is true about spoiler
A. When a spoiler surface on one wing fails, the symmetric one on the other wing is inhibited.
B. If the system loses hydraulic pressure, the spoiler retains a lesser deflection if aerodynamic forces push it down.
C. all of the above

[单选题]Which of the following is correct about the rated N1 mode?
A. An automatic reversion to rated N1 mode occurs in the event of loss of sensed EPR. This occurs when P2 (engine inlet total pressure) and/or P5 (LP turbine exit total pressure) engine parameters are not available.

[单选题]Which of the following is true about the lavatory smoke detection and extinguishing？
A. Each lavatory wastebin has an automatic fire extinguishing system.
B. When a detector finds smoke in a lavatory, it sends a signal to the CIDS, which transmits it to the Flight Warning Computer (FWC), for Warning in the cockpit, and generates an indication in the cabin.
C. all of the above
