1. The problem statement, all variables and given/known data why does a pilot tend to black out when pulling out of a steep dive? 2. Relevant equations Newton's 2nd and 3rd laws 3. The attempt at a solution I think the pilot passes out because the downward force of the plane pushes all the blood away from his brain and causes him to pass out. I read the rules of this forum so I don't expect an answer. But please push me in the right direction because I know I am forgetting something.
