N2由什么组成：The N2 is comprised of a:

发动机运行限制：当推力手柄在MCT位时，N1指示最大值是多少？ENGINE OPERATING LIMITS: what’s the maximum limit of N1 indication while the power is MCT

发动机运行限制：当推力手柄在慢车位时，N1指示范围是多少？ENGINE OPERATING LIMITS: what’s the range of N1 indication while the power is idle

判断正误：允许使用HIGH PWR SCHEDULE 电门。True or False:Use of the HIGH PWR SCHEDULE switch is Allowed.

发动机暖机：对于任何时候，启动后的_____分钟内油门不要超过______N1或者直到所有的发动机工作参数在正常范围内。Engine Warm-up: During all starts, do not exceed ___% N1 for ___ minutes after start, or until all operating indications are in the normal range, whichever is longer.

判断正误：发动机暖机：推力手柄必须在慢车位直到滑油压力达到正常工作范围True or False:Engine Warm-up: The engine must remain at IDLE until oil pressure reaches normal operating range.

判断正误：当发动机运转时以及引气设定于起飞状态，机组必须证实目标N1数值和推力设定图表上一致(±1.0%) 。True or False:With the engines running and bleeds configured for take-off, the crew must verify that the target N1 values correspond to the data presented in the thrust setting charts (±1.0%).

发动机限制值EICAS系统上由各种符号，图形或颜色来显示最大值或最小值以及警示范围，那么滑油的警戒温度范围（黄色）是多少？The engine limit display markings on EICAS must be used to determine compliance with the maximum/minimum limits and precautionary ranges. What is the caution range of OIL TEMP °C (amber)

发动机限制值EICAS系统上由各种符号，图形或颜色来显示最大值或最小值以及警示范围，那么N1%RPM在0-99.4%显示的颜色是什么？The engine limit display markings on EICAS must be used to determine compliance with the maximum/minimum limits and precautionary ranges. The color of N1% RPM 0 to 99.4% in EICAS

飞机冷透后，当天首次飞行前，发动机必须冷转（ ）秒，并且在起动发动机之前确认风扇转动。After airplane cold soak, before the first flight of a day, the engines must be motored for( )seconds and the fan rotation must be verified before an engine start is initiated.

当N2达到%（ ） rpm时，起动机马达脱开。Starter motor cut-out occurs at percent N2 rpm.
