Jeppesen
American company
Jeppesen (also known as Jeppesen Sanderson) is an American company offering navigational information, operations planning tools, flight planning products and software. Jeppesen's aeronautical navigation charts are often called "Jepp charts" or simply "Jepps" by pilots, due to the charts' 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.
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 Gdańsk (Poland). The company employs approximately 3,200 people.
History
The company was founded in 1934 by Elrey Borge Jeppesen, a pilot working for Varney Air Lines, who was the first to make aeronautical charts for pilots to navigate in flight. The information that he collected and the charts that he drew were at first only for personal use, but fellow pilots quickly saw the benefits of using these charts, and Jeppesen started selling copies of his chart book for $10. Other pilots started to collect data on their own routes and gave it to Jeppesen for him to include in his navigation book.
