This Section must set forth each mandatory replacement time, structural inspection interval, and related structural inspection procedure required for type certification.

A. The smoke sensor in each detector monitors when the smoke density is above a previous limit. If the density keeps higher than the limit for about eight seconds, the sensor set the detector to the alarm condition.

B. The smoke sensor in each detector monitors for smoke density above a preset limit. If the density stays above the limit for appropriately eight seconds, the sensor sets the detector to the alarm condition.

C. The smoke transducer monitors for smoke density above a presumed limit of each detector. If the density remains over the limit about eight seconds, the transducer turn the detector to the alarm condition.

A. 对邻近区域做检查。

B. 对表面区域做检查。

C. 对内部区域做检查。

A. 记录对蒙皮表面进行的所有修理。

B. 记录对蒙皮封严进行的所有修理。

C. 记录对蒙皮损伤进行的所有处理。

A. “细节要求”部分给特殊材质的物品进行整理和排序提供特定方法。

B. “具体要求”部分描述了特殊材料的实体的一致性布局和辨别的方法。

C. “详细要求”部分提供了编排和标识特定主题材料的统一方法。

A. 确保没有剪断操纵钢索。

B. 确保没有关断控制电源。

C. 确保没有连接控制电缆。

A. 飞机总体布局应该包括平面图、侧面图和前视图的刻度说明。

B. 飞机总体布局应由刻度线图画来阐释，包括计划图、侧视图和前视图。

C. 飞机的总体布局应由比例尺线条图阐明，包括平面图、侧视图和前视图。

A. Solid the sealant at a peripheral temperature.

B. Cure the sealant at a uniform temperature.

C. Solid the sealant at the same temperature.

A. When a low flow or undercooling condition occurs, the low flow sensor sends an alarm signal to the flight compartment for warning.

B. When a low flow or not sufficient cooling condition occurs, the low flow sensor supplies an alarm signal to the flight compartment for annunciation.

C. When a low flow or insufficient cooling condition occurs, the low flow sensor applies a alarm signal to the flight compartment for caution.

A. Each system is composed of basic components and all equipment, mechanic controls and system related electric and hydraulic units.

B. Basic components and all apparatus are made up of each system, including mechanical controls and electrical and hydraulic units related sytem.

C. Each system includes the basic components and all instruments, mechanical controls, electrical and hydraulic units related to the system.

A. “基准面”是一个假想的垂直面。以基准面为准来测量用于计算平衡的水平距离。

B. “基准面”上有一架假设的垂直平面，出于平衡考虑，所有的力矩距离都是从它开始测量。

C. “基准面”是一个假想的垂直平面，所有的横向距离都是从它开始测量的，以达到平衡的目的。
