| 7 | devising a range of different boarding methods | 设计一系列不同的登机方法; |
| 8 | and testing them with computer simulations. | 用电脑模拟测试它们 |
| 9 | These models are designed to consider the two biggest plane-loading bottlenecks. | 这些模型旨在考虑两个最大的飞机装载瓶颈. |
| 10 | The first is seat interference, | 第一个是座位干扰 |
| 11 | when someone in a seat closer to the window | 当有人坐在靠近窗户的座位上 |
| 12 | is blocked by people already in their row. | 被已经排成一排的人挡住了 |
| 13 | And the second is aisle interference, | 第二个是过道干扰, |
| 14 | when passengers seated in the back of the plane | 当乘客坐在飞机后座时 |
| 15 | are stalled by folks in earlier rows stowing their bags and settling in. | 被更早排队的人困住了 把他们的包和安顿下来。 |
| 16 | Different boarding methods try to tackle these problems in different ways, | 不同的登机方式试图以不同的方式解决这些问题, |
| 17 | but the most commonly used approach is called back-to-front boarding. | 但最常用的方法叫后登机 |
| 18 | It seems logical— board the back of the plane first, | 看起来很合理 先登上飞机后座 |
| 19 | so passengers don't need to pass others to reach their seats. | 所以乘客不需要通过其他人才能到达座位. |
| 20 | And in simulations using a 156-passenger Airbus A320, | 在模拟中使用156客机A320, |
| 21 | where every person has a carry-on, | 在那里,每个人都有随身携带, |
| 22 | back-to-front boarding takes around 23 minutes. | 23分钟后返航 |
| 23 | Not bad, though it barely outperforms the opposite strategy, | 不错,虽然它的表现 勉强超过相反的策略, |
| 24 | boarding front-to-back, | 登机前对后, |
| 25 | suggesting it's not actually doing much to reduce interference. | 说明它实际上没有做很多 减少干扰。 |
| 26 | Other airlines have tried to speed things up by ditching assigned seating altogether, | 其它航空公司试图通过完全放弃分配的座位来加快速度, |
| 27 | assuming that passengers naturally spread out, easing congestion. | 假设乘客自然分散,缓解拥堵. |
| 28 | Random seating shaves a few minutes off boarding the A320, | 随机坐着会刮去几分钟的A320号机 |
| 29 | but it's not perfect. | 但它并不完美。 |
| 30 | The line tends to slow down at the end, | 线路在尾部会减速 |
| 31 | as passengers search for remaining seats. | 作为乘客寻找剩下的座位。 |
| 32 | And while the freedom might help you avoid a crying toddler, | 虽然自由可以帮助你避免一个哭泣的孩子, |
| 33 | it can also split up groups who board later. | 也可以分拆后登机的团体. |
| 34 | To keep assigned seating and further reduce delays, | 为了保持分配的座位并进一步减少延误, |
| 35 | mathematicians developed the outside-in, or WMA, method, | 数学家开发了外在的,或者WMA,方法, |
| 36 | which loads passengers in window seats first, then middle, and finally aisle seats, | 首先把乘客装在窗口座位上 然后是中间 最后是过道座位 |
| 37 | bringing boarding time down to just 16.5 minutes. | 把登机时间缩短到16.5分钟 |
| 38 | Still, some experts, including astrophysicist Jason Stephan, | 然而,一些专家,包括天体物理学家杰森·史蒂芬, |
| 39 | felt there was room for improvement. | 觉得还有改进的余地 |
| 40 | Stephan ran countless boarding order simulations until he found the fastest one. | 史提芬进行了无数的登机订单模拟,直到他找到最快的登机订单. |
| 41 | His order, aptly named the Stephan method, | 他的命令,恰当地命名为史提芬方法, |
| 42 | can fully board the A320 in just 15 minutes. | 15分钟内就能完全登上A320 |
| 43 | So why don't airlines use it? | 那为什么航空公司不用它? |
| 44 | Well, Stephan's method requires passengers to load on in a very specific pattern. | 斯德芬的方法要求乘客以非常具体的模式装载. |
| 45 | First, it fills even rows, then odd rows, | 首先,它填满了连排,然后是奇数排, |
| 46 | using a combination of the WMA and back-to-front methods. | 使用WMA和后置前置方法的组合. |
| 47 | By staggering passengers across the cabin, | 乘客横跨客舱 |
| 48 | it gives everyone just enough room to load their carry-ons all at once. | 给每个人足够的空间 让他们能马上装满行李 |
| 49 | But Stephan's method demands perfect execution. | 但是史提芬的方法需要完美的执行. |
| 50 | Not only does it require all passengers to arrive at the gate on time, | 不仅要求所有乘客准时到达大门 |
| 51 | but also that they line up in their exact assigned order | 但他们依预定的顺序排队, |
| 52 | and be willing to split from their families as they board. | 愿意在登船时与家人分离 |
| 53 | While this level of passenger cooperation might seem far-fetched, | 虽然这种程度的旅客合作似乎牵强, |
| 54 | it's not unprecedented. | 这不是前所未有的。 |
| 55 | In the early 1970s, Southwest implemented a policy | 1970年代初,西南地区执行了一项政策 |
| 56 | where planes would land, unload, board, and push back all in under 10 minutes. | 飞机会在10分钟内降落 卸货 登机 全部推回 |
| 57 | As soon as the plane touched down, | 飞机一降落 |
| 58 | attendants began unloading bags into the aisles. | 服务员们开始把行李卸到过道上。 |
| 59 | By the time it reached the gate, | 当它到达大门时, |
| 60 | new passengers were already lined up on the tarmac, | 新乘客已经排在停机坪上 |
| 61 | boarding as others de-planned. | 登机是计划外的 |
| 62 | People were still finding seats as the plane taxied toward the runway. | 人们仍然在寻找座位 当飞机滑向跑道。 |
| 63 | Such a system wouldn't fly by today's aviation standards. | 这种系统不会按今天的航空标准飞行。 |
| 64 | There are also engineering options to explore. | 还有一些工程选项可供探索. |
| 65 | Loading a plane with 240 seats through two doors instead of one | 通过两扇门而不是一扇门装上240个座位的飞机 |
| 66 | can potentially speed up boarding by five minutes. | 有可能加速5分钟登机 |
| 67 | Another proposal, the side-slip seat, offsets the middle seat, | 另一个提案是侧滑座位, 抵消中间座位, |
| 68 | allowing the aisle seat to slide over it and temporarily widen the aisle, | 允许过道的座椅滑过它 并暂时拓宽过道, |
| 69 | potentially reducing boarding times by up to 20%. | 有可能将登机时间减少20%。 |
| 70 | However, while faster boarding times may save airlines on operational costs, | 然而,虽然更快的登机时间可以节省航空公司的业务费用, |
| 71 | it's unlikely they'd actually invest in these redesigns, | 他们不可能真的投资 这些重新设计, |
| 72 | since there's also value in keeping the process aggravating. | 因为让过程恶化也是有价值的 |
| 73 | Long lines mean passengers are more willing to pay for tickets | 长线意味着乘客更愿意买票 |
| 74 | that allow them to get on the plane first. | 让他们先上飞机 |
| 75 | It's frustrating, but before you cancel your tickets, | 很沮丧,但是在你取消票前 |
| 76 | it's worth noting that there really isn't much time to be saved. | 值得注意的是,真的没有多少时间可以挽救。 |
| 77 | Even the most perfectly executed boarding strategy | 即使是最完美的登机策略 |
| 78 | would likely only save us about 10 minutes. | 可能只节省我们大约10分钟。 |
| 79 | So perhaps the best solution is to take a breath, | 所以,也许最好的解决方案 是呼吸, |
| 80 | allow your fellow passengers some grace, | 让你的乘客们享受一些优雅 |
| 81 | and try to enjoy the ride. | 并尝试享受乘坐。 |
