A charter pilot, also known as an air taxi, flies passengers on a private plane whenever and wherever the paying client asks. These are typically flights with short durations, and charter pilots often fly single-engine planes. In some cases, your duties in this involve making regularly scheduled flights if you work for a small airline company. Your responsibilities are the same as other pilots in the industry and include the transportation of a customer and compliance with all Federal Aviation Administration (FAA) rules and regulations. You can find an air taxi at a major airport, as well as smaller, private ones.
