How to Read This Guide 如何阅读本指南

An orange cell signifies a cruise altitude a little too high for that aircraft at that weight that carries smaller fuel penalties.

A green cell signifies a cruise altitude appropriate for that aircraft at that weight going East, maximizing fuel economy.

A blue cell signifies a cruise altitude appropriate for that aircraft at that weight going West, maximizing fuel economy.

A grey cell signifies a cruise altitude that is too low for that aircraft at that weight that may or may not carry a small or large fuel penalty.

Fuel Capacity is simply the maximum fuel that can be loaded onto that aircraft.

Game-Estimated Maximum Flight Time is the flight time that Infinite Flight tells you when you fully fuel your aircraft.

Theoretical Maximum Flight Time is the flight time calculated from these numbers that is theoretically possibly, waiving all IFR altitude rules and reserve fuel rules.

Practical Maximum Flight Time is the flight time calculated from these numbers that takes into account a 90% passenger and 75% cargo load (75% cargo load only for the Freighter), IFR altitude rules, and reserve fuel rules.

Flight Profiles are the ideal sequences of cruise altitudes for an aircraft at different loads.

橙色格子表示该飞机在该重量下的巡航高度有点过高,会有较小的燃油浪费。

绿色格子表示该飞机在该重量下适合向东飞行的巡航高度,最大限度地提高燃油经济性。

蓝色格子表示该飞机在该重量下适合向西飞行的巡航高度,最大限度地提高燃油经济性。

灰色单元表示该飞机在该重量下的巡航高度太低,可能会有或不会有或大或小的燃油浪费。

燃油容量只是指该飞机可装载的最大燃料。

游戏估计最大飞行时间是Infinite Flight告诉你,当你给飞机加满油时的飞行时间。

理论最大飞行时间是指从这些数字计算出的飞行时间,理论上可能,放弃所有IFR高度规则和储备油规则。

实际最大飞行时间是指根据这些数字计算出的飞行时间,其中考虑了90%的载客量和75%的载货量(75%的载货量仅适用于货机)、IFR高度规则和储备油规则。

航班资料是飞机在不同载荷下巡航高度的理想序列。

Disclaimers 免责声明

Disclaimer I : Numbers are from solo testing and have not been tested live yet.

Disclaimer II : The 757 has speed dip, meaning it sits at M 0.79 when set to 0.80. Measurements were taken with the AP at 0.80.

Disclaimer III : To keep it simple, I only took measurements every 10% load. If there were huge drops in fuel burn over those 10% I tried to take them into account when determining the climb profile.

Disclaimer IV : I am assuming linear rate of change of fuel burn between 10% increments. This is likely not the case, but it should be close enough.

Disclaimer V : Numbers in charts are in pounds. Works all the same for kilograms just different numbers.

免责声明一:数字来自于单机测试,尚未进行实测。

免责声明二:757有速度下降,也就是说,当设置为0.80时,它坐在M 0.79处。测量时AP在0.80时进行。

免责声明三:为了简单起见,我只每隔10%的负荷进行测量。如果在这10%以上的燃料燃烧有巨大的下降,我试图在确定爬升曲线时将其考虑在内。

免责声明四:我假设燃料燃烧的线性变化率在10%的增量之间。这很可能不是事实,但应该足够接近。

免责声明五:图表中的数字是以磅为单位。对于公斤来说,工作原理都是一样的,只是数字不同。

757-200

Fuel Capacity : 76,968 lbs or 34,912 kg

Game-Estimated Maximum Flight Time : 10hr 17m

Theoretical Maximum Flight Time : 11hr 41m

Practical Maximum Flight Time : 9hr 53m (Eastbound) | 9hr 49m (Westbound)

Flight Profile (East): FL310 (100%-41%), FL390 (40%-21%), FL410 (20%-0%)

Flight Profile (West): FL300 (100%-71%), FL320 (70%-41%), FL400 (40%-0%)

燃油容量:76,968磅或34,912公斤。

游戏预计最长飞行时间:10小时17分钟

理论最大飞行时间:11小时41分

实际最长飞行时间:9小时53分(东行)|9小时49分(西行)。

飞行概况(东)。FL310(100%-41%)、FL390(40%-21%)、FL410(20%-0%)

飞行概况(西)。FL300(100%-71%)、FL320(70%-41%)、FL400(40%-0%)

Key Takeaways 主要心得体会

The 757 burns fuel predictably and reasonably. No need to pack a ton extra.

The 757 is not the most efficient at standard altitudes. You don’t need to avoid FL330-FL380, however, as the numbers aren’t that different.

The 757 is forgiving. Even if you pick the wrong altitudes, it won’t bite you.

757的燃料燃烧可预测且合理的。 不用多带一吨的东西。

757在标准高度上的效率并不是最高的。 不过,你不需要避开FL330-FL380,因为数字相差不大。

757很宽容。 就算你选错了高度,它也不会吃你。

Enjoy 20.3! 享受20.3吧!
