【中英双语】非官方的起降数据档案[757]


Lake Tahoe, California 太浩湖,加州

Welcome to the Unofficial Takeoff and Landing Profiles guide for the Boeing 757! This gorgeous aircraft comes with two powerful engines to get you off the ground at airports with runways as short as 5700ft. With this power, its important to understand how and when to use these engines as well as the flaps to its max in short field situations.

This brief guide should get you into the air as well as on your way to a successful landing in just a few minutes. The table below should be pretty self explanatory for the most part, but please don’t hesitate to ask any questions you may have. Please read through the notes sections throughout the topic as well as at the end of this tutorial for further clarification on some of the items found within the table.

欢迎来到波音757的非官方起飞和降落概况指南! 这架华丽的飞机配备了两个强大的发动机,让你在跑道短至5700英尺的机场起飞。有了这样的动力,重要的是要了解如何和何时使用这些发动机,以及在短场情况下最大限度地使用襟翼。

这个简短的指南应该让你起飞以及在短短几分钟内成功着陆。下面的表格应该是相当自我解释的大部分,但请不要犹豫,你可以问任何问题。请阅读整个主题的注释部分,以及在本教程的最后,进一步澄清一些项目在表中发现。

Bonus: There is a Quick Reference Guide at the end of this tutorial. You’re more than welcome to download and save the PDF for imminent and future use.
奖励:在本教程的最后有一个快速参考指南。我们非常欢迎你下载并保存这个PDF文件,以便于近期和将来使用。

Purpose 目的:

The purpose of this guide is to provide you with ball park speeds, flap settings, and power settings to get you in the air and onto the runway in one piece. These values are not 100% accurate as each flight is different. Weather, airport elevation, weight, runway length and other factors will affect your these values.

本指南的目的是为您提供速度、襟翼设置和动力设置,让您在空中完美地飞上跑道。这些数值并不是100%准确的,因为每个航班都是不同的。天气、机场海拔、重量、跑道长度和其他因素都会影响这些数值。


Conditions 条件:

Tests were conducted at Honolulu International Airport (PHNL)
我们在火奴鲁鲁国际机场(PHNL)进行了测试。
/// Airport Elev. 13ft 机场高度 13英尺 \\\

  • Winds Calm 风平浪静
  • Runway 08R 跑道08R
  • Temperature Standard (15˚C) 温度标准(15˚C)
  • All initial pitch angles were 15˚ nose up until 1000ft. AFE (Above Field Elevation) before pitch was dropped to increase speed 所有的初始俯角都是15˚机头,直到1000英尺。俯仰角下降以提高速度前的AFE(场面高度以上)。
  • Heavy Departure/Landing conducted at 98% load. Adjust as necessary. 在98%的负荷下进行重型起降。必要时调整。

  • Landing flare pitch should be about 2.5˚ nose up.

  • Descent rate should not exceed -1000ft/min on final approach

  • 着陆照明灯仰角在机头向上2.5˚左右。

  • 在最终进场时,下降速度不应超过-1000英尺/分钟。


**Note 注: Depending on the length of runway, weight, terrain and other considerations, a higher flap setting may be desired.
根据跑道的长度、重量、地形和其他考虑因素,可能需要较高的襟翼设置。

Extra note 附加说明: At airports such as KSNA, KSAN and KDCA where the 757 has operated IRL, Flaps 15 were predominately used due to runway length. PHLI departures would use Flaps 20 due to heavy transpacific loads and short runway use. Be cautious of aircraft weight and use an appropriate amount of power for takeoff.
在诸如KSNA、KSAN和KDCA等机场,由于跑道长度的原因,757飞机主要使用襟翼15。PHLI起飞时,由于跨太平洋载荷大、跑道短,会使用襟翼20。注意飞机重量,起飞时使用适当的动力。

***Heavy Departures/Landings 重型起飞/降落: Takeoffs over 75% may result in takeoff over Maximum Takeoff Weight (MTOW). This may also result in runway overruns. This could lead to overweight landings depending on your configuration. Consider all factors and risks.
超过75%的起飞可能会导致超过最大起飞重量(MTOW)的起飞。这也可能导致跑道超限。根据您的配置,这可能导致超重降落。考虑所有因素和风险

‡ Note ‡注: APPR is disabled for landings greater than the load below for where the Maximum Landing Weight (MLW) lies:
对于最大着陆重量(MLW)位于以下载荷的着陆,APPR将被禁用:

  • 64%

Flaps 襟翼:

For reference the flap and various limitations for each setting are listed below. These can also be found in the cockpit of the 757 on the flap indicator gauge, to the left of the gear lever.

下面列出了襟翼和各种限制的设置,供参考。这些也可以在757飞机驾驶舱内的挡杆左边的襟翼指示表上找到。

Flaps 襟翼 Speed Limitation 速度限制
1 240 kts
5 220 kts
15 210 kts
20 195 kts
25 190 kts
30 162 kts

General Notes 一般说明:

  • For 25-50% loads, Flaps 5 was used for data
    对于25-50%的荷载,襟翼5用于起飞。
  • For 75-100% load, Flaps 15 was used for data
    对于75-100%的负荷,襟翼15用于起飞
  • "Airborne By 起飞速度" indicates a speed that you should be off the ground no later than. By the time you reach this speed, you should be in the climb and gear in the retraction process.
    表示你应该不迟于离开地面的速度。当你达到这个速度时,你应该在爬升和起落架在收回过程中。
  • Takeoff Power 起飞动力- The first percentage is your throttle amount. The second value is the N1 read out as indicated in green above your throttle.
    第一个百分比是你的油门量。第二个值是N1读出的数值,在你的油门上方绿色显示。
  • 100% throttle should never be used. 绝对不能使用100%的油门。 Aircraft in the real world very rarely exceed 100% as this is mainly used for emergencies only.
    飞机在现实世界中很少超过100%,因为这主要只用于紧急情况。
  • 25% trim was used to conduct these tests
    进行这些测试时使用了25%的配平

Note 注: Fuel flow, thrust and other aircraft performance factors may apply.
燃料流量、推力和其他飞机性能因素可能会适用

Boeing 757 QRG 波音757 快捷指南:

If you would like a quick reference guide, you’re more than welcome to utilize this one that I’ve condensed into a 1 page sheet. It has just about everything you’ll want to know in terms of “What do I use for takeoff/cruise/landing?” and “When do I add/remove flaps or power?”. Below is a screenshot of what this document looks like as well as a PDF download link for that crisp picture and saving for future use.

如果你想要一个快速的参考指南,你肯定会很喜欢利用这个我浓缩成1页纸的指南。它几乎包含了所有你想知道的 “起飞/巡航/着陆干什么?”“什么时候添加/移除襟翼或动力?”。以下是该文件的截图,以及PDF下载链接,以便于日后使用。


Questions 问题?

Feel free to add any questions or other helpful tips/pointers that you may find beneficial to others and myself or our helpful community members will gladly address those.

Please also check out other guides I have created for other recently new/reworked aircraft. I plan on making this “unofficial” series a regular thing as aircraft are reworked or new from the factory as a handful of folks seem to appreciate the quick start information.

欢迎添加任何问题或其他有用的提示,你可能会发现这些问题对其他人有益,而我和我们的社区成员也很乐意解决这些问题。

也请查看我为其他最近的新飞机/返修飞机创建的其他指南。我计划把这个 "非官方 "的系列变成一个定期的事情,因为有一些人似乎很欣赏快速指南的信息,飞机也是返工的或新出厂的。

Have fun! :airplane:
玩得开心!:flight_departure:
