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.
