787 Spoiler Photo interesting

I noticed in a photo of one of the 787 test articles that the highspeed aileron deflects up during rollout to act as a spoiler.
Are there any other airplanes that use the aileron like this?

The CRJ 100/200 spoilerons and the E175 multi-function spoilers have similar functions. Speedbrake at altitude and a spoiler for landing when logic conditions are met.

This might be a feature on the 787, but judging by the fact that the outboard aileron is also deflected up, I think it's more likely that they just have crosswind correction applied.
 
My guess is that he was retracting the flaps before touchdown and that confused the system causing both outboard ailerons to deflect up.

Beside who cares? As long as he cancels before reaching the gate.

Who cares? Um, well I care, because I like learning new things about aircraft that I don't fly.
But I see what you were doing there with the cancelling ifr thing.

Yes that seems a very likely scenario... I'll dig around for a photo from the front or rear so I can see both wings while landing.

Actually I was wrong. It does do what you said:

Purty fancy!
 
FBW is a beautiful thing.

There have been lots of planes with aileron droop for the flap. I'm glad they finally decided to throw it in as a barndoor after touchdown as well.

Especially since EVERYTHING is electrical.
 
Is that thing ever going to make it to the line ? I mean the company has 10 ordered, 1.5 billions out, and yet the company has to buy more A330 and sign a firm order for 10 350WXB's. Needless to say that the airline CEO is not the happiest camper around... This is delaying the opening of direct Asia routes from South America, a much needed market considering the large Asian community here, it hampers the airline development and generally sheds a very bad light on Boeing. Interestingly, this company was the first Boeing operator in South America, and has now a 95% Airbus fleet. Way to go, Boeing.

FedEx. A380. Anyone?

There is a big difference between the ratio of FedEx A380F orders to total A380F orders and the relationship between CarrierX 787 orders versus total 787 orders. Not really a valid comparison, but I get your point.

For those of you who think that the 787 program will be cancelled? Well, pity is felt for you.

Has there been recent talks in canceling the program?

Known as decelerons, there are a few aircraft that use them....

My old mount, the A-10. The A-6 Intruder/EA-6 Prowler series, and the B-2 Spirit.

They are building/testing/modifying a large jet. Give it a second to build/test/modify a large jet.
