There are many factors we should consider to make sure we have sufficient fuel on board. For example, the distance and time of the flight, the aircraft weight, the weather en route, the wind condition and fuel consumption rate and so on.为确保飞机有充足燃油，我们需考虑诸多因素。比如，飞行距离与时长、飞机重量、航线天气、风况以及燃油消耗率等等 。

There are many factors we will consider when calculating the fuel quantities for each flight such as weight and balance, weather conditions, altitude and airspeed and so on.计算每次飞行燃油量时，我们会考虑诸多因素，比如重量与平衡、天气条件、高度和空速等等 。

Minimum fuel is not considered as fuel emergency. It just means that we cannot accept excessive delay. But emergency fuel means the fuel is not enough we must request priority landing.最低燃油不视为燃油应急状态，仅表示无法接受过长延误；应急燃油则表示燃油不足，必须申请优先着陆。 Minimum fuel is an informational notice to ATC, indicating potential fuel emergency if delayed. Emergency fuel is a distress situation where fuel is insufficient to reach the destination, requiring immediate priority landing with ATC assistance. 最低燃油是向空管发出的提示信息，表明若延误可能引发燃油紧急情况；而紧急燃油是已出现燃油不足以到达目的地的遇险状态，需立即请求空管协助优先着陆。

I fly the DA-40, which is equipped with two main fuel tanks, one in each wing. For large commercial aircraft like the B737 or A320, there are usually multiple fuel tanks, including wing tanks and a center tank, to meet long-haul flight fuel requirements and maintain weight balance.我驾驶的DA-40飞机配备两个主油箱，左右机翼各一个。对于波音737、空客A320等大型民航客机，通常设有多个油箱，包括机翼油箱和中央油箱，以满足长途飞行的燃油需求并保持重量平衡。

（1）Pilots calculate fuel endurance based on remaining fuel quantity (monitored via fuel gauge), current fuel consumption rate, flight speed, and altitude. They also refer to flight plan data and adjust for weather factors (e.g., headwind) to estimate remaining flying time.飞行员通过燃油表监控剩余燃油量，结合当前燃油消耗率、飞行速度和高度计算续航力。同时参考飞行计划数据，并根据天气因素如逆风进行调整，以估算剩余飞行时间。 （2）We can calculate fuel endurance based on the full fuel and fuel used on the ECAM or EICAS. Besides, we can calculate the fuel endurance based on the flight time and the rate of fuel consumption. 我们可以根据电子中央飞机监控系统（ECAM）或发动机指示和机组警告系统（EICAS）上的满油量与已用油量计算燃油续航能力。此外，我们还可以根据飞行时间和燃油消耗率来计算燃油续航能力 。

I think pilots play an important role in saving fuel, because the pilot controls the aircraft in most flight operations. If the pilot controls the aircraft too slow or too fast, it will influence the fuel consumption. What's more, pilots can choose the optimum/economical speed, altitude and route to save fuel.我认为飞行员在节约燃油方面发挥着重要作用，因为在大多数飞行操作中，是由飞行员控制飞机的。如果飞行员把飞机控制得太慢或太快，会影响燃油消耗。此外，飞行员可以选择最佳 / 经济的速度、高度和航线来节约燃油 。 Pilots play a crucial role in fuel saving. Reasonable selection of altitude, speed, and route, smooth maneuvering, and avoiding unnecessary holding or go-arounds can significantly reduce fuel consumption. It not only cuts company costs but also protects the environment, with safety as the top priority. 飞行员在节油中扮演关键角色。合理选择高度、速度和航线，平稳操作，避免不必要的等待或复飞，都能大幅降低燃油消耗。这不仅能降低公司成本，还能保护环境，同时需以安全为首要前提。

If we use contaminated fuel, it will significantly degrade the engine performance, even make the engine flame out or engine failure.如果我们使用受污染的燃油，会显著降低发动机性能，甚至导致发动机熄火或发动机故障 。 Using contaminated fuel can block fuel filters or pipes, leading to insufficient or interrupted fuel supply. It may cause engine power loss, flame-out, vibration, or even damage to engine components, seriously endangering flight safety. 使用污染燃油会堵塞燃油滤清器或管路，导致燃油供应不足或中断，可能造成发动机功率下降、熄火、振动，甚至损坏发动机部件，严重危及飞行安全。

There are many factors that may affect fuel consumption/economy such as weather conditions, airspeed, altitude, the weight of the aircraft, the pilot's flight skills and so on.有诸多因素可能影响燃油消耗 / 经济性，比如天气条件、空速、高度、飞机重量、飞行员的飞行技能等等 。 Factors include weather conditions (wind, turbulence), airspeed and altitude selection, aircraft weight, piloting skills (smooth maneuvers), wind direction, and aircraft configuration. Optimal altitude and speed, reduced unnecessary maneuvers improve fuel efficiency. 影响因素包括天气条件风、颠簸、空速和高度选择、飞机重量、驾驶技巧平稳操作、风向以及飞机构型。选择最佳高度和速度、减少不必要操作可提升燃油效率。

Before each flight, the ground mechanics are responsible for refueling. I will check the fuel quantity before flight.每次飞行前，由地面机务负责加油。我会在飞行前检查燃油量 。

（1）I have not back to the company yet. But I know our company fuel policy is good, they encourage pilot to save fuel. But in any cases, we must ensure the flight safety first.我尚未回到公司。但我知道我们公司的燃油政策很不错，鼓励飞行员节约燃油。但在任何情况下，我们都必须首先确保飞行安全。 （2）As I know, the airlines often encourage pilots to save fuel. The pilots who save fuel will be rewarded. That is to say, if the pilots save fuel, they will get more money. 据我所知，航空公司通常鼓励飞行员节约燃油。节约燃油的飞行员会得到奖励。也就是说，如果飞行员节约了燃油，他们会拿到更多钱  （3） My company encourages fuel saving while prioritizing flight safety. Fuel quantity is calculated based on flight plan, weather, weight and balance, diversion, and holding needs. Pilots get bonuses for fuel saving, and we must comply with regulations on minimum fuel and reserve fuel. 我们公司在优先保障飞行安全的前提下鼓励节油。燃油量根据飞行计划、天气、载重平衡、备降和等待需求计算，飞行员节省燃油会有奖励，同时必须遵守最低燃油和储备燃油相关规定。

According to regulations, minimum fuel is not a fuel emergency. It means if there is any further delay, fuel emergency will be declared. For IFR flights, it refers to fuel endurance less than 45 minutes at 3000ft over the destination airport.根据规定，最低燃油并非燃油紧急情况，而是指若再出现延误，将宣布燃油紧急。对于仪表飞行规则IFR飞行，指在目的地机场上空3000英尺高度时，燃油续航时间不足45分钟。

According to our company flight operation manual, if we fly in holding airspeed the fuel endurance for keeping 1500 feet overhead the airport is less than 30 minutes, we should declare fuel emergency and request priority landing.依据我们公司飞行操作手册，若以等待空速飞行，在机场上空 1500 英尺高度保持飞行的燃油续航时间不足 30 分钟时，我们应宣布燃油紧急情况并申请优先着陆 。 Fuel emergency is declared when the remaining fuel is insufficient to reach the destination or alternate airport, there is serious fuel leakage, changes in clearance force using reserve fuel, or the aircraft has less than 30 minutes of endurance. It requires immediate ATC assistance for priority landing. 当剩余燃油不足以到达目的地或备降机场、出现严重燃油泄漏、航线许可变更导致需使用储备燃油，或飞机续航时间不足30分钟时，需宣布燃油紧急情况，立即请求空管协助优先着陆。

There are some reasons for fuel shortage on board. For example, fuel leak, diversion, long delay, insufficient fuel quantity before flight.飞机上燃油不足有多种原因，比如燃油泄漏、改航、长时间延误、飞行前燃油量不足 。  Fuel shortage can be caused by strong headwinds, fuel leakage, prolonged low-altitude flight, incorrect speed or configuration, excessive holding or go-arounds, miscalculation of fuel quantity during preflight planning, or fuel contamination. 强逆风、燃油泄漏、长时间低空飞行、不当的速度或构型、过多的等待或复飞、飞行前燃油量计算错误以及燃油污染等，都可能导致机上燃油短缺。

（1）Firstly, I will contact ATC, request climb for dumping fuel and vectors to the fuel dump zone. During the fuel dumping process, the controller will advise other pilots to avoid flying into the fuel dumping area. After fuel-dumping completed, I will inform the ATC and request back to the course.首先，我会联系空中交通管制（ATC），申请爬升以进行燃油放油，并请求引导至放油区。在燃油放油过程中，管制员会提醒其他飞行员避开放油区域。放油完成后，我会告知 ATC 并申请回到原航线。 （2）First, report to ATC, request clearance to the designated fuel dumping area. Then, follow SOP to activate the dumping system, monitor fuel quantity and aircraft status, and stop dumping once the target weight is reached, ensuring no impact on ground or other aircraft. 首先向空管报告，申请进入指定放油区域的许可；然后遵循标准操作程序启动放油系统，监控燃油量和飞机状态，达到目标重量后停止放油，确保不对地面或其他飞机造成影响。

（1）  Fuel dumping is needed when the aircraft encounters an emergency requiring return or diversion, and its weight exceeds the maximum landing weight. For example, in cases of landing gear failure or belly landing, dumping fuel reduces weight and the risk of fire/explosion.当飞机遭遇紧急情况需返航或备降，且重量超过最大着陆重量时，需执行放油程序。例如，起落架故障或需机腹着陆时，放油可降低飞机重量，减少起火或爆炸风险。 （2）There are some situations we will dump fuel. First, if the landing weight exceeds the maximum landing weight, we will dump fuel. Second, if we will make an emergency landing such as belly landing, we will dump fuel. 存在一些需放油的情况。其一，若着陆重量超过最大着陆重量，需放油。其二，若要进行紧急着陆（如机腹着陆），需放油 。

（1）Fuel dumping is not allowed over crowded residential areas, cities, lakes, rivers, forests, or low airspace. These areas have high population density or ecological sensitivity, and dumping fuel may cause pollution, injuries, or accidents.飞行中不允许在人口密集的居民区、城市、湖泊、河流、森林以及低空空域放油。这些区域人口密度高或生态敏感，放油可能造成污染、人员伤亡或事故。 （2）As I know, fuel dumping is not allowed over the cities and rivers because it may cause air pollution or water pollution and it may influence people's lives. 据我所知，城市和河流上空不允许放油，因为这可能造成空气污染或水污染，还可能影响人们的生活 。

If we have to dump fuel, we need radar vectors from ATC to the dump area.若我们必须放油，需要 ATC 通过雷达引导我们前往放油区域

Before each flight, the pilot is responsible for checking the fuel quality. We will drain an amount of fuel out and check if the color is OK. We must make sure the fuel quality is good. Because if we use contaminated fuel, it will significantly degrade the engine performance, even make the engine flame out or engine failure.每次飞行前，飞行员负责检查燃油质量。我们会放出一定量燃油，检查其颜色是否正常。必须确保燃油质量良好，因为若使用受污染燃油，会显著降低发动机性能，甚至导致发动机熄火或故障 。

The pilots shall declare fuel emergency by stating the remaining fuel on board, fuel endurance in minutes and the intention of priority landing.需说明机上剩余燃油量、燃油续航时间（以分钟计）及优先着陆的意图。

Pilots can save fuel by selecting the optimum cruising altitude and speed, requesting direct routes or straight-in approaches, reducing unnecessary maneuvers, avoiding prolonged holding, and maintaining stable flight. Skilled operation and good preflight planning also contribute to fuel efficiency.飞行员可通过选择最佳巡航高度和速度、申请直飞航线或直线进近、减少不必要操作、避免长时间等待以及保持稳定飞行来节油。熟练的操作和良好的飞行前规划也有助于提升燃油效率。

No. Dumping fuel over city areas is strictly prohibited. It may pollute the environment, endanger ground personnel and property, and cause potential safety hazards. Fuel must be dumped in designated areas such as high altitude over oceans, mountains, or wilderness.不可以。严禁在城市区域放油，这可能污染环境、危及地面人员和财产安全，存在潜在安全隐患。燃油必须在指定区域，如海洋、山区或荒野上空的高高度进行排放。

During refueling, we must make sure the refueling area is cleared and safe, far away from the fire source.加油期间，我们必须确保加油区域已清空且安全，远离火源 。 During refueling, key safety factors include: turning off electronic devices, ensuring fuel is not contaminated, having fire extinguishers standby, connecting ground wires, and avoiding refueling during thunderstorms or poor visibility. 加油过程中需考虑的安全因素包括：关闭电子设备、确保燃油无污染、备好灭火器、连接接地线，以及避免在雷暴或低能见度条件下加油。

If I encounter fuel leakage during refueling, I will stop refueling immediately and ask the ground mechanics to check the leakage.若我在加油期间遇到燃油泄漏情况，我会立即停止加油，并让地面机务检查泄漏情况 。  I will immediately stop refueling, inform ground staff and ATC, request fire services as a precaution, keep away from fire and electronic devices, have fire extinguishers ready, and wait for maintenance personnel to inspect and handle the leakage. 我会立即停止加油，通知地面人员和空管，预防性请求消防服务，远离火源和电子设备，备好灭火器，等待维修人员检查并处理泄漏问题。

If I encounter fuel leakage during flight, I will follow the SOP and perform the checklist try to solve the problem. Then advise ATC of our situation, if necessary, I will request divert to the nearest suitable airport and request ground mechanics help to check the leakage.若我在飞行中遇到燃油泄漏，我会遵循标准操作程序（SOP），执行检查单来尝试解决问题。然后将我们的情况告知空中交通管制（ATC），如有必要，我会申请改航至最近的合适机场，并请求地面机械师协助检查泄漏情况 。

Firstly, we can visual check the fuel tank. Secondly, we can check the fuel quantity indicator. At last, we can use the fuel dip stick to make sure we have correct amount of fuel on board.首先，我们可以目视检查燃油箱。其次，我们可以查看燃油量指示器。最后，我们可以使用燃油量油尺，确保飞机上有正确的燃油量 。

I will report to ATC we have "minimum fuel", tell the controller how much fuel we left on board and we cannot be delayed any further. If we need diversion, I will request nearest suitable airport information and weather information to avoid further delay.我会向 ATC 报告我们处于 “最低燃油” 状态，告知管制员飞机剩余燃油量，以及我们无法再承受延误。若需要改航，我会请求最近合适机场的信息和天气信息，以避免进一步延误 。

Before departure, we must get the loading sheet from the dispatcher.起飞前，我们必须从调度派人员（dispatcher）处获取装载单 。

I will immediately inform ATC of the fuel shortage and situation, request priority landing at the nearest suitable airport, simplify flight procedures, avoid unnecessary maneuvers, and monitor fuel quantity closely to ensure safe landing.我会立即向空管报告燃油短缺情况和当前状态，申请优先降落到最近的合适机场，简化飞行程序，避免不必要操作，密切监控燃油量，确保安全着陆。

（1）Yes, I think so. Because at the higher cruising altitude, the more stable the outside air is, the air density is lower, so there is less drag, it will help to reduce fuel consumption.是的，我认为有助于。因为在更高的巡航高度，外界空气更稳定，空气密度更低，所以阻力更小，有助于降低燃油消耗。 （2）Generally yes. At high altitude, air density is lower, reducing aircraft drag, which helps save fuel. However, fuel consumption is also affected by aircraft limitations, weight, and engine performance. We need to select the optimum cruising altitude instead of blindly flying too high. 通常是可以的。高高度空气密度更低，会减小飞机阻力，从而有助于节省燃油。但燃油消耗还受飞机限制、重量和发动机性能等因素影响，我们需选择最佳巡航高度，而非盲目高飞。

I think pilots play an important role in saving fuel, because the pilot controls the aircraft in most flight operations. If the pilot controls the aircraft too slow or too fast, it will influence the fuel consumption. What's more, pilots can choose the optimum/economical speed, altitude and route to save fuel.我认为飞行员在节约燃油方面发挥重要作用，因为在大多数飞行操作中，是由飞行员控制飞机的。如果飞行员把飞机控制得太慢或太快，会影响燃油消耗。此外，飞行员可以选择最佳 / 经济的速度、高度和航线来节约燃油 。

I think our company's fuel policy is good. They encourage pilots to save fuel and reduce operation costs. If we follow the fuel policy, we can get rewards.我认为我们公司的燃油政策很好。它鼓励飞行员节约燃油、降低运营成本。如果我们遵守燃油政策，还能获得奖励 。 It’s a positive policy. Fuel saving reduces company operational costs and is environmentally friendly. However, safety must never be compromised for fuel saving. Pilots should not avoid necessary go-arounds or cut reserve fuel; instead, achieve fuel efficiency through scientific operation and planning. 这是一项积极的政策。节油能降低公司运营成本，且有利于环境保护。但绝不能为了节油而牺牲安全，飞行员不应避免必要的复飞或削减储备燃油，而应通过科学操作和规划实现节油。

Fuel contamination can be caused by inadequate preflight inspection, lack of maintenance, improperly filtered fuel supply, and presence of water, sand, or other debris in fuel tanks. Contaminated fuel may block filters, cut off fuel supply, and lead to engine power loss or shutdown.燃油污染的成因包括飞行前检查不充分、维护不当、燃油供应过滤不达标，以及油箱内混入水、沙子或其他杂物。受污染的燃油可能堵塞过滤器、切断燃油供应，导致发动机动力损失甚至熄火。

Of course, if there is water in the fuel tank, the water may turn into ice at high altitude and sometimes it will cause the engine surge and engine failure. It’s very dangerous for the flight safety.会。若油箱中有水，高空环境下水分可能结冰，有时会导致发动机喘振甚至失效，对飞行安全极具威胁。

Yes. During flight training and operations, I have participated in aircraft refueling. Before refueling, we calculate the required fuel quantity based on the flight plan. During refueling, we monitor the process to check for contamination or leakage, and confirm the fuel quantity after refueling.有过。在飞行训练和运行中，我参与过飞机加油。加油前，我们根据飞行计划计算所需燃油量；加油过程中，监控加油情况，检查燃油是否污染或泄漏；加油后，确认燃油量是否符合要求。
