Abstract: PROBLEM TO BE SOLVED: To provide a navigation information apparatus, for helicopter navigation, by which the navigation stability of a helicopter is made maximum by a method wherein a navigation route, a separation distance and a safe altitude are presented visually by using a present position, a present altitude which are received from a global positioning system and by using input topographical information and to provide its control method. SOLUTION: An apparatus is constituted of a GPS receiving antenna 1 which receives a GPS signal to be sent from an artificial satellite and of a GPS reception part 2 in which the GPS signal received by the GPS receiving antenna 1 is processed so as to detect position information. In this case, the apparatus is composed of storage parts 3, 4, 5 which store data about a map, an altitude and a position, of an input part 8 which inputs data required for the route setting operation and and the navigation of a helicopter, of a control part 6 in which the position data received by the GPS reception part is compared with the data on the map and the altitude so as to be judged on the basis of the route to be set by the input part 8 and in which navigation data on a safe distance, a separation distance or the like is created, of a display part 7 in which the navigation data by the control part 6 is presented to a pilot and of a navigation-information storage part 9 which records the navigation data permanently.
