Re: 787 vs A350 range

In order to verify validity of our calculations, I decided to compare FCOM data against actual Computer Flight Plans from my recent flights on the 788 and 789. In case of the 789, I was also able to include the actual fuel burn on the flight. Below are the results with all the data required to cross...

What surprised me about the A332 is it is only around 8% above the 789/359, the 338 was supposed to have a drop of more than that. Will gladly have a look and will try to throw in...

Re: 787 vs A350 range

Depends on sector length, looks like the A350 burns about 1% less at longer ranges, and easily carries the same payload too far. Bring back solar powered aircraft. That confirms what we’ve already known - that the A350 is optimised for higher stage lengths and payloads. Now, however, we were able t...

Re: 787 vs A350 range

As I said, this is just an assumption of a 'typical' flight. The 787 can do ~54T payload, but I hardly ever see more than 40 in day-to-day ops for a full-ish plane. Perhaps other carriers normally carry more cargo. Likewise the reserves - 8-10T is what I usually see after landing, which normally inc...

It has more thrust for takeoff and can use thrust to fly a lot further, or in addition to the better wing to achiev...

O.K., I checked it.

After all, the 330 wing had been designed for a significantly heavier A340. Personally I ...

The wing sizing and weights are very similar between the 330 and the 789, is the approach speed difference due to the fact that the bus has a thicker wing that can produce lift better at low speeds?
