Re: A320 Series Spoilers

The since they put the newer engines on the spoiler function of the aileron seems to have been removed. The only logical reason I can think of is due to the forces that act on the wing with the heavier engines but that’s just a guess. That's what surprises me. I've flown recently the 320neo with vu...

Can you expend on this? What do you call a spoileron (aileron behavior on landing with SHARP mod?) and when was it removed?

Re: 787 electrical architecture efficiency vs traditional systems

This brings me nicely to my next question : where Boeing went electric with the 787, what did Airbus do on the 350 for the equivalent systems?
Asked otherwise : appart from aerodynamic and engine improvements, how did Airbus increase other aircraft systems efficiency compared to previous generation?

What I think you're seeing there is that the 787 actually has *more* visibility to the sides of those front windows. If you were to actually measure that central pillar, I'll bet it's within an inch of the L1011. That photo is definitely giving you a trick of perspective due to the wider angle lens...

It's not BS - it's fact. The reason ALPA had an issue with it is because crew contracts enabled them to essentially avoid social security taxes in the countries that they were operating in.

Thanks mpdpilot for your reply. First, the videos are all just of one side of the aircraft.
