Jeppesen (also known as Jeppesen Sanderson) is an American company that specializes in navigational information, planes, operations management and optimization solutions, crew and fleet management solutions and flight training products and services. Jeppesen serves four market segments (Commercial Aviation, Business Aviation, Military, and General Aviation). Airlines and private pilots, airline operations centers, military teams, ship operators and boaters, as well as railway companies use Jeppesen charts, data, and operations management tools. The company is a subsidiary of Boeing. Jeppesen also publishes related software, some of which is used on its electronic flight bag and in others offered by avionics manufacturers and other third parties. Jeppesen is headquartered in Inverness, Colorado, a census designated place in Arapahoe County. The postal designation of Englewood is used in the company’s mailing address. Jeppesen has offices in locations around the world, including Neu-Isenburg (Germany), Massa (Italy), Crawley (United Kingdom), Gothenburg (Sweden), Canberra (Australia) and Gdansk (Poland). The company employs approximately 3,200 people. In the navigation space, which is where Jeppesen started, Jeppesens charts are often called "Jepp charts" or simply "Jepps" by pilots, due to the charts' de facto popularity. This popularity extends to electronic charts, which are increasingly favored over paper charts by pilots and mariners as mobile computing devices, electronic flight bags, integrated electronic bridge systems and other display devices become more common and readily available.
