While clubs are a great place to learn to fly and attain your pilots licence, they offer a great deal more.
Your licence is the recognition of reaching a level of competence to allow you to fly an aircraft safely in the aviation environment and to carry passengers. But like all other sports, your level of competence and confidence will increase with practice and experience.
Most pilots enjoy extending their skills by gaining ratings in different types of aircraft, joining Club flyaways and other activities, participating in competitions, or learning an advanced skill like formation flying or aerobatics. Some even progress to a CPL, not to gain employment but to attain additional skills.
You will not only learn from your own experience, clubs look after your extended needs and will provide assistance when planning flights into areas new to you. You will also learn anecdotally by mixing with fellow members, many with hundreds of hours of experience.
Members of aeroclubs range from Young Eagles (most clubs have a Young Eagle group) to those in their 80's and 90's, They come from all walks of life. While the very senior members may no longer be able to fly without an instructor, they form part of the very diverse group who are the social fabric of the club and attend club dinners and other events.
