What kind of pilot would fly after a drink? Not you, right? Good. Same here, but if we are being honest, how many of us have experienced signs of hypoxia (oxygen deficiency) while at the controls?
Consider the need for life rafts and life vests. On extended overwater flights, you’ll want to carry one life vest per person and a raft (or rafts) with enough room and buoyancy to fit everyone on board.
You have probably heard of CO or Carbon Monoxide; the colorless, odorless, highly toxic gas. Have you ever thought about it hovering in your cockpit during flight?
