Patent number: 9520065Abstract: A navigation aid information display device of an aircraft and primary flight display for an aircraft are disclosed. In one aspect, the navigation aid information display system includes a display screen including at least one first display area configured to display a first altitude scale including graduations, the current altitude of the aircraft on the first scale, and set altitude value. The graduations of the first scale are distributed on an arc of a first disc including a first needle centered in the disc and the first needle is configured to indicate the current altitude on the first scale. The distribution of the graduations on the arc is nonlinear and symmetrical relative to a graduation corresponding to the set altitude value and defines extension graduations decreasing from the set altitude value.Type: GrantFiled: September 22, 2014Date of Patent: December 13, 2016Assignee: THALESInventors: Bruno Aymeric, Xavier Servantie, Cécile Andre

Patent number: 7353091Abstract: The field of the invention is that of methods of synthesizing cartographic images presented on display devices. This method is applied more specifically to visual flight on rotary-wing aircraft. The method according to the invention is used to present the useful aeronautical map information superimposed on a conventional altimetric presentation of the terrain being flown over, while retaining a legibility that is acceptable to the user. Flight safety is thus significantly reinforced. To obtain an enhanced legibility, the method displays only the aeronautical zones included in an altitude band corresponding to the flight phase of the aircraft and dependent on the geographic location and the vertical position of the aircraft. The method is used to display the cartographic representation either on a single window comprising a plan view of the terrain being flown over, or on two windows respectively representing a plan view and a cross-sectional view of the terrain being flown over.Type: GrantFiled: August 9, 2005Date of Patent: April 1, 2008Assignee: ThalesInventors: Xavier Servantie, Alain Goetz, Eric Filliatre

Publication number: 20050052451Abstract: The field of the invention is that of methods for the synthesis of a 3D mapping image consisting of pixels and representing the distribution of the intervisibility area on a terrain overflown by an aircraft. An intervisibility area is understood to mean the area within range of a known potential threat. The method of the invention represents the intervisibility area in the form of the surface layer constituted by points belonging to the sphere covered by the threat, such that the distance from each point of the surface layer to the point of the terrain having the same geographical coordinates should be as small as possible. This arrangement enables the aircraft pilot to have very clear and very easily interpretable information available to him. Furthermore, the method requires limited computation resources. This facilitates its implementation in onboard mapping generators.Type: ApplicationFiled: November 19, 2003Publication date: March 10, 2005Inventor: Xavier Servantie
