Since then, all modern jets and even some turboprops have come with their own APUs.

从那时起，所有现代喷气式机甚至一些涡轮螺旋桨机都配了自己的 APU。

However, APUs aren't all good news.

然而，APU 也不全是好消息。

Indeed, some airports have restricted APU  usage at night to soothe local communities.

事实上，一些机场已限制 APU 在夜间使用，以安抚当地社区。

The APU was filled with water from natural and artificial reservoirs up to 3 meters deep.

APU 充满了来自深达 3 米的天然水库和人工水库的水。

From cabin lights to  avionics onboard, APUs have become essential for modern jets.

从机舱灯到机载航空电，APU 已成为现代喷气式机必不可少的。

This means crews will generally  switch off the APU when taking off and reignite it while cruising for emergency  use.

味着机组人员通常会在起时关闭 APU，并在巡航时重新点燃以紧急使用。

Unusually, the APU on the 727 was not in  the rear of the aircraft.

不同寻常的是，727 上的 APU 并不在机的后部。

Did you know about the  presence and role of the APU?

您知道 APU 的存在和作用吗？

APUs became common in the 1960s, with Boeing  including the first commercial APU for a jetliner in the 727 in 1963.

APU 在 1960 年代变得普遍，波音公司在 1963 年为 727 的喷气客机配了首个商用 APU。

The best way to do this is to start  the APU (which is not normally running in flight).

最好的方法是启动 APU（它通常不会在中运）。

The presence of an APU in the 727 allowed airlines to avoid reliance on ground power at smaller  airports.

APU 在 727 中的存在使航空公司能够避免在较小的机场依赖地面动力。

The APU will power critical functions  like cockpit displays and radios, as well as passenger comforts like air conditioning, heating, lights, and galley equipment.

APU 将为驾驶舱显示器和收音机等关键功能提供动力，以及空调、供暖、灯光和厨房等乘客舒适施。

Especially if we really are a couple of years away from the next generation of consoles, it's very easy to imagine a full eight-core Ryzen CPU set up inside a console APU.

特别是如果我们离下一代游戏机还有几年的时间，我们不难想象在一台游戏机的 APU 中置一个完整的8核 Ryzen CPU。

If you've been grateful for cheaper tickets, longer nonstop flights, and a cool cabin when you  walk onboard, the APU is to thank in many cases.

如果您对更便宜的机票、更长的直航班和凉爽的机舱感到感激，那么在很多情况下， APU 就是感谢。

An APU is a small turbine  engine that, on modern jets, is attached to the rear fuselage of the aircraft to provide power  onboard when the main engines are switched off.

APU 是一种小型涡轮发动机，在现代喷气式机上，它安装在机的后机身，以便在主发动机关闭时提供机载动力。

By utilizing the APU  bleed air for an engine start, it allows pilots to select the best lift to drag ratio speed to extend  the glide range during engine re-start attempts.

通过利用 APU 引气启动发动机，它允许员选择最佳升阻比速度，以在发动机重新启动尝试期间扩大滑翔范围。
