So the VR speed for a 787 isn't going to be set like a Cessna 172, it's going to be a calculated value depending on weight, temperature, etc. The computers will calculate this speed for you before flight, assuming all info is input correctly.

The cockpit won't be able to see the flaps visually but will have a digital indicator that shows the position. During pre take-off checks one of the procedures would be to check this indicator for the correct setting.

With the very limited available info and the fact that video shows it slowly descending without obvious external mechanical issues, my initial guess is on pilot or computer error.

    Some people were saying, based on a video of the crash that it might have been mechanical, as they heard the sound of the RAT that only deploys on double engine failure.

    Also, wouldn't a bad config cause a full-on stall? It seemed more of a controlled glide to me.
