尊敬的旅客：
您好！自北京时间2018年1月21日零时起，您可以在遵守本使用规范的前提下，在国航实际承运航班上使用便携式电子设备（Portable Electronic Devices，简称PED）。具体如下：
出于安全原因：
一、我们全程禁止在航空器上使用的电子设备，包括但不限于发射功率在100mW（含）以上、Wi-Fi工作频率不在2.4GHz波段的便携式电子设备，如无发射功率标识的手机、卫星电话、移动Wi-Fi、对讲机、无人机遥控平台、遥控玩具和其他带遥控装置的便携式电子设备。
二、在滑行、起飞爬升和进近着陆等飞行关键阶段禁止使用，在非飞行关键阶段允许使用的便携式电子设备包括但不限于：
1.未经认证品牌的便携式氧气浓缩器（POC）;
2.笔记本电脑、平板电脑等。
三、全程允许使用的电子设备，包括但不限于： 心脏起搏器；助听器；不会影响飞机导航和通讯系统的用于维持生命的电子设备（装置），如认证品牌的便携式氧气浓缩器（Portable Oxygen Concentrator,简称POC），持续正压呼吸机（Continuous Positive Airway Pressure,简称CPAP）。单手可握持的小型便携式电子设备，如智能手机、电子书、视频播放器、游戏机等，关闭蜂窝通信功能选择飞行模式后可在飞行全程使用。在飞行关键阶段应关闭Wi-Fi和蓝牙等功能，且不得连接耳机、充电、数据连接等外围设备，不得使用语音和数据通信。
四、在飞行期间，当机长发现存在电子干扰并怀疑该干扰来自于您使用的便携式电子设备时，以及机长必须执行低能见运行程序和启动紧急撤离时，为防止干扰飞机通信和精密导航设备，我们有权要求您关闭便携式电子设备。
此通知。
Dear passengers:
Effective from 00:00 January 21, 2018,Beijing time, you can use the portable electronic equipment (PED) on Air China-operated flight, subject to the required regulations. For safety reasons:
I. A total ban is imposed on the use of electronic devices on board for the whole journey, including but not limited to portable electronic devices with transmission power of 100mW (inclusive) above and Wi-Fi frequency not on 2.4GHz band, such as mobile phone without transmission power labels, satellite phones, mobile Wi-Fi, walkie talkie, UAV remote control platform, remote control toys and other remote control portable electronic devices.
II. The use of some types of portable electronic devices is NOT allowed in the critical stages of flight, such as taxiing, takeoff, climb, approach and landing, but is allowed in the non-critical stages. Such devices include, but are not limited to:
1. Portable Oxygen Concentrator (POC) of non-certified brands;
2. Laptop, portable tablet, etc.
III. Electronic devices whose use is allowed during the entire journey include but not limited to: Pacemaker; hearing aids; electronic devices that will not affect aircraft navigation and communication systems and help maintain life such as certified Portable Oxygen Concentrator (POC) and Continuous Positive Airway Pressure. (CPAP); small portable electronic devices that can be held with a single hand such as smart phone, e-book, video player, game device and so on (these can be used during the entire flight if the cellular communication function is turned off and the flight mode is chosen. During the critical stages of flight, Wi-Fi and Bluetooth should be shut down, and it is not allowed to connect them with peripheral devices such as earphones, charger, data connector, etc.; it is not allowed to use voice and data communication.
IV. During the flight, if the captain found the presence of electronic interference, suspecting that such and electronic jamming interference comes from your portable electronic devices, and when the captain must perform low visibility operational procedures and activate emergency evacuation, in order to prevent the interference with aircraft communication and navigation precision equipment, we have the right to demand you to shut down your PED. If you violate the regulations on the ban, restriction and use regarding PED, refusing to obey the instructions of our crew, and if the circumstances are serious, we shall have the right to hand you over to the public security organs after landing for further handling based on the laws.
