This is about how the human body adapts and copes, or doesn’t cope with flight – particularly the effects of high altitude and oxygen starvation – hypoxia. It starts with basic health and fitness and moves on to understanding the cardiovascular and respiratory systems. Then we look at the balance mechanisms in your inner ear, and how your eyes react to the illusions of flight. Barotrauma is about trapped gasses in your body that can cause misery such as severe toothache. And how your body responds to G loading. Then there is very interesting stuff on vertigo, the leans, and graveyard spirals, and how stress, fatigue, and ergonomics effect your decision making. Finally we look at communications, first aid and survival on land and in water.
