If we encounter an engine fire during flight, first, we will report the situation to ATC and request an emergency landing. Second, we will cut off the fuel supply to the faulty engine, activate the fire suppression system (discharge fire bottles) to extinguish the fire. If necessary, we will shut down the faulty engine.若飞行中遭遇发动机起火，首先，会向空中交通管制（ATC）报告情况并申请紧急降落；其次，切断故障发动机的燃油供应，启动灭火系统（释放灭火瓶 ）灭火；如有必要，会关闭故障发动机 。

No, I have never encountered engine fire during flight.没有，我在飞行中从未遇到过发动机起火情况。

If there is smoke or fire in the cockpit, first, we will put on oxygen masks. Second, we will report the situation to ATC, request an emergency descent, and arrange for an immediate landing.若驾驶舱内出现烟雾或火情，首先，我们会佩戴氧气面罩；其次，向空中交通管制（ATC）报告情况，申请紧急下降并安排立即着陆 。 Don oxygen mask immediately, identify the smoke source if possible, and isolate it. Ventilate the cockpit/cabin (open side window for light aircraft). Report to ATC, declare emergency, and request priority landing at the nearest airport. Follow QRH procedures for smoke/fire handling. 立即佩戴氧气面罩，尽可能识别并隔离烟雾源；为驾驶舱/客舱通风（轻型飞机打开侧窗）；向空管报告并宣布紧急状态，请求在最近机场优先着陆；遵循快速检查单（QRH）的烟雾/火情处置程序。

If we receive a report of smoke in the cabin during cruise, first, we will report the situation to ATC and request an emergency landing at the nearest suitable airport, along with arranging emergency services. Second, the cabin crew will attempt to extinguish potential fires using fire extinguishers. Third, we will help remove smoke by activating air vents or relevant ventilation systems.若巡航阶段收到客舱烟雾报告，首先，我们会向空中交通管制（ATC）报告情况，申请在最近的合适机场紧急着陆，并协调应急服务；其次，乘务组会使用灭火器尝试扑灭可能存在的火情；最后，我们会通过开启通风口或相关通风系统来协助排除烟雾 。

If smoke emerges from the cabin in this scenario, first, we will report the situation to ATC and request an immediate return for landing. Second, we will dump fuel to reduce the aircraft’s weight and lower the landing speed, facilitating a safer landing. After landing, we will conduct an emergency evacuation.若出现此客舱烟雾情况，首先，向空中交通管制（ATC）报告并申请立即返场着陆；其次，进行放油操作，减轻飞机重量、降低着陆速度，保障着陆安全；着陆后，实施紧急撤离 。 Maintain aircraft control, inform cabin crew to assess smoke source and provide first aid. Report to ATC, declare emergency (squawk 7700), and request priority landing at the nearest airport. Do not climb to high altitude; keep thrust stable. Prepare passengers/crew for potential evacuation after landing. 保持飞机控制，通知客舱机组评估烟雾源并提供急救；向空管报告，宣布紧急状态（应答机编码7700），请求在最近机场优先着陆；不爬升至高空，保持推力稳定；让乘客/机组准备好落地后可能的撤离。

If we are going to land with fire on board, we will request fire - fighting services, medical emergency services, and aircraft salvage services as needed.当机上有火情准备着陆时，我们会请求消防服务、医疗急救服务，必要时还会请求航空器打捞救援服务 。

There are common causes of engine compartment fire. First, fuel leaks or oil leaks in the engine compartment may lead to fires. Second, mechanical failures of the engine itself can result in fires. Third, errors during maintenance procedures might cause fires in the engine compartment.发动机舱起火有以下常见原因：一是发动机舱内燃油泄漏或滑油泄漏，可能引发起火；二是发动机自身出现机械故障，会导致起火；三是维修作业过程中存在失误，可能造成发动机舱起火 。

Engine fire in flight may result from bird/debris ingestion, ice ingestion, fuel or oil leakage, fuel contamination, mechanical failures, or maintenance issues. These factors can ignite fuel or oil, leading to fire, reduced thrust, or even engine shutdown, endangering flight safety.飞行中发动机起火可能由鸟类/碎片吸入、积冰吸入、燃油或滑油泄漏、燃油污染、机械故障或维护问题导致。这些因素会点燃燃油或滑油，引发火情，造成推力下降甚至发动机失效，危及飞行安全。

On board, fire suppression bottles are used to extinguish engine fires, and portable fire extinguishers are utilized for cabin fires.机上灭火时，发动机火情使用灭火瓶（ suppression bottles ）处置，客舱火情则用便携式灭火器 。 Onboard fire extinguishers (such as Halon 1301, HFCs) are primary equipment. Other tools include fire blankets (for small fires), emergency evacuation slides (to isolate fire areas), and APU shutdown (to cut off fuel supply for engine fires). 机上灭火器（如哈龙1301、氢氟烃类）是主要设备，其他工具包括灭火毯（用于小火）、紧急撤离滑梯（隔离火区）以及辅助动力装置（APU）关闭（切断发动机火情的燃油供应）。

Follow SOP and engine fire checklist: shut down the affected engine, cut off fuel/electrical supply, activate fire extinguishers. Maintain aircraft control, report to ATC, declare emergency, and request diversion to the nearest suitable airport. Prepare for emergency landing and evacuation if needed.遵循标准操作程序（SOP）和发动机火警检查单：关闭故障发动机，切断燃油/电源供应，启动灭火器；保持飞机控制，向空管报告并宣布紧急状态，请求改航至最近合适机场；必要时准备紧急着陆和撤离。
