"Explaining the 'what' and the 'why' when instructing also results in greater knowledge and understanding by the student, which in turn leads to greater situational awareness. For example, to say 'Do not fly into a thunderstorm' provides insufficient information. The instructor must explain the 'what,' 'why' and 'how.' What is a thunderstorm? Why do you want to avoid it? How do you avoid it? Consider three levels of situational awareness: notice — the wind is 270/20G30; understand — 270/20G30; I've got a crosswind of 25 knots: think ahead — what am I going to do if the wind increases? What if? By teaching pilots to attain a higher level of situational awareness, they have more pertinent information to feed into the decision-making process, thereby allowing better judgment."
