a question for pilots
Discussion
I went to the airbus freinds and family day at filton last saturday and witnessed an A380 taking off and doing a show.
The take off and immediate turn was a
moment, i di not know it was possible for something that big stay in the air when moving that slowly!
My friend says that the flight control system will not allow manouvers that go beyond pre determined minimums. i.e to exceed these limits would mean it would stall etc.
Is this true?
What if in an emergency situaion, too exceed these perameters for a few seconds, might mean a pilot may be able to prevent disaster?
Surely an override would be beneficial?

The comments (and voiceover) of that video are priceless: an unmanned A320? Airbus is fly by wire - the pilot uses a side stick to give inputs to the Flight Management System. The FMS then decides how to move the control surfaces based on the pilot inputs and which "law" it is currently set to follow.
These "laws" govern how much influence the FMS has to override what the pilot asks.
As a non pro pilot, thats about the extent of my confirmed anoraksis knowledge.
But basically - there is "normal law" meaning the aircraft wont let you do something silly, "alternate law" meaning some of the restrictions are lifted, and "you're on your own pal law" meaning.....well......
If you have Sky tv, have a search for Bruce Dickinson "Flying Heavy Metal" where he has a go in an Airbus and tries to stall it over the Pyrannees. Very impressive demonstration of what it can (can't!) do.

thanks, I have sky. Is this on sky anytime?These "laws" govern how much influence the FMS has to override what the pilot asks.

A good few of the comments say it's unmanned.
Most comments on YouTube are by idiots; I don't understand why you are referring to them.It is however easy to understand the concept of both computer and pilot trying to fly the 'plane and those instructions conflicting.

Here's the report on that accident.

However, there is plenty of conjecture out there that there was a bit of a cover-up and not all of it came from people who think tin-foil hats are an essential piece of headwear.

The aircraft didn't stop them from recovering; the pilot did. He descended too low and only when the trees loomed in the distance did the pilot's brain fart clear. By the time he applied go around thrust it was too late. If they'd been in a Boeing then they'd have simply stalled into the trees as opposed to flying into them at the optimum pitch angle allowed by the flight computers.
