【简答题】
Learning to fly from a flight instructor is one of the most exciting and costly opportunities that student pilots can have. He will be the most influential person in our careers to fly. Instructors are life savers: Making a mistake in a plane can lead to a lot of problems unless the instructor is qualified. Often, the quality of a pilot, especially in the early stages, is a reflection of the quality of the person who has taught them. During flight training, the instructor will save us and the aircraft from many of our mistakes, possibly fatal. Therefore, an instructor is supposed to have appropriate experience and knows how to correct the problem, or in extreme cases take over and save both of our lives. Good instructors make great pilots: It is important to have a strict instructor who will work with us in order to reach perfection. A patient instructor can make young pilots feel confident in their abilities. Also, teaching technique is very important. Many instructors prefer to teach in briefing rooms before taking students up into the air. Others bring students up in the air right at the beginning and teach them how to fly by having them fly.
