  1. The answer is commonly 12,
  2. which is simply we can have 6 state variables,
  3. and in each of those the helicopter might have its own velocity.
  4. So for each of these variables, we have the state variable itself
  5. and its velocity, which makes a total of 12.
  6. This is completely nontrivial and something you probably can't know.
  7. We just have to learn, but when you think about it, you realize this is the most general case
  8. of a vehicle that can move in 3D at every possible location,
  9. every possible orientation at any velocity.
  10. That's called the dynamic state of a free-flying object.
