The whole muscle of which the muscle fibres are a part can develop force in several different ways, e.g. with the muscle as a whole shortening, lengthening or maintaining the same length while the muscle fibres contract. List of types of muscle contraction. Isotonic (of which there are two types: concentric and eccentric)
While some flight schools will advertise that you can get a pilot's license for around $5,000, the reality is that the cost generally works out to be more. A commercial pilot's license -- bigger plane, more than twice the flight time -- generally costs $40,000 to $50,000.
In recent years, the average cost of a private pilot certificate ranges anywhere from $12,000 - $15,000. It is possible, with a lot of hard work and preperation for each lesson, for the average person to complete their training within this range, at our current rates.
