In an answer, a user linked to this video of the gust alleviation system (GAS) on an A380. This seems like a complex system with many moving parts—all the ailerons move completely independently. What happens if the GAS fail, if for instance two ailerons get stuck in an extreme position?
Or maybe even worse: imagine a sensor failure that produces two opposite extremes on each wing, such that e.g. the left wing have all its ailerons in the up position, and the right wing ailerons in the down position.
- Could this be fatal?
- Are there procedures for this in some checklist?
This is a follow-up for my other question, What is a gust alleviation system?.
This is not question Why do some aircraft have multiple ailerons per wing? as far as I can possibly see (though it was marked as such).
