CREW OXY MASKS | USE |
SIGNS | ON |
EMER DESCENT | INITIATE |
If A/THR not active:
THR LEVERS | IDLE |
SPD BRK | FULL |
When descent established:
SPEED | MAX / APPROPRIATE |
If structural damage suspected: MANEUVER WITH CARE
CONSIDER L/G EXTENSION
ENG MODE SEL | IGN |
ATC | NOTIFY |
Notify ATC of the nature of the emergency, and state intention. The flight crew can communicate with the ATC using voice, or CPDLC when the voice contact cannot be established or has poor quality.
EMER DESCENT (PA) | ANNOUNCE |
The flight crew must inform the cabin of emergency descent on the PA system.
EMER DESCENT (PA) | ANNOUNCE |
The flight crew must inform the cabin of emergency descent on the PA system.
ATC XPDR 7700 | CONSIDER |
Squawk 7700 unless otherwise specified by ATC.
CREW OXY MASKS DILUTION | NORM |
‐ To save oxygen, set the oxygen diluter selector to the N position
‐ If the oxygen diluter selector remains set to 100 %, oxygen quantity may be insufficient to cover the entire emergency descent profile
‐ Ensure that crew communication is established with oxygen masks. Avoid the continuous use of the interphone to minimize interference with the breathing noise in the oxygen mask.
MAX FL: 100/MEA-MORA
If CAB ALT above 14 000 ft:
OXYGEN PAX MASK MAN ON | PRESS |
This action confirms that the passenger oxygen masks are released.
Note: Notify the cabin crew, when the aircraft reaches a safe flight level, and when
cabin oxygen is no more necessary.
机组氧气面罩 使用
信号牌 ON
紧急下降 开始
如果自动推力未生效:
推力手柄 慢车
减速板 FULL
当建立好下降时：
速度 最大/合适
如果怀疑结构损坏： 小心机动
考虑放起落架
发动机方式选择器 IGN
ATC 通知
通知 ATC 紧急情况的性质并说明意图。飞行机组可用语音同 ATC 联系，或当不能建立语音联系或通话质量差时可用 CPDLC（管制员飞行员数据链接通讯）。
应急下降 (PA) 宣布
飞行机组必须通过 PA 系统通知客舱应急下降。
ATC 应答机 7700 考虑
应答机7700，除非ATC另有指示。
机组氧气面罩稀释 NORM位
为节约氧气，将氧气稀释选择器放到N（正常）位。
如果氧气稀释选择器保持在 100 % ，氧气量可能不足以覆盖整个应急下降剖面。
确保戴上氧气面罩后建立好机组通讯。避免持续使用内话，以将氧气面罩中的呼吸噪音干扰减至最小。
最大飞行高度层: 100/MEA-MORA
如果座舱高度高于14 000 ft：
OXYGEN PAX MASK MAN ON PRESS
该动作确认旅客氧气面罩放出。
注: 当飞机到达安全飞行高度层并且不再需要客舱氧气时，通知客舱机组。
