Definitions
- the present invention relates to on-board navigation aid for aircraft in accordance with a part of a flight plan corresponding to a low altitude trajectory which may include passages with freedom of lateral movement limited by the risk of collision with the ground. It relates to a signaling, on a navigation screen, of passages of the flight plan trajectory subject to restrictions on freedom of lateral movement.
- a navigation screen of the dashboard of an aircraft a first image showing a map of the region overflown with, in superimposition, the position of the aircraft and the trace on the ground of the part to be covered of the trajectory provided in the flight plan, and a second image showing the relative height of the aircraft with respect to a vertical navigation profile which lists the highest elevations of terrain encountered along a strip of land centered on the trajectory provided in the flight plan, called the navigation strip.
- the elevations of the region overflown are listed in an on-board topographic database or searchable from the aircraft.
- the navigation strip has a width on either side of the track on the ground of the trajectory planned in the flight plan, taking into account the uncertainties in the location of the aircraft, the inaccuracies of the topographic database and the lateral tolerance allowed in following the trajectory provided in the flight plan.
- the vertical navigation profile informs the crew of the aircraft on the height margin above the ground that the aircraft has according to their position on the trajectory provided in the flight plan and their current altitude given by their instruments. from the edge but it does not give any indication of the environment close to the navigation strip which may, when the aircraft is at low altitude, limit its freedom of lateral movement.
- the relief and the obstacles on the ground are listed in a topographic map of the region overflown prepared from a topographic database on board or viewable from the aircraft.
- the lateral protection volumes linked to the aircraft are dimensioned so as to contain the volumes necessary for lateral clearance maneuvers. This is a system requiring, like all TAWS systems, relatively large computing power.
- the object of the present invention is to assist on-board navigation providing information, at a lower cost, to the crew of an aircraft on the passages of the trajectory provided for in their flight plan where they will encounter limitations in their lateral margins of maneuver.
- It relates to a method for signaling the lateral margins of maneuver existing on either side of a trajectory provided in the flight plan of an aircraft provided with a location device and having access to a database of elevation of terrain, remarkable in that it consists of displaying, on a navigation screen, with the vertical navigation profile giving the highest elevations of terrain listed in the terrain elevation database, encountered on the planned trajectory in the flight plan, along a navigation strip whose width takes into account the aircraft location uncertainties, the inaccuracy of the terrain elevation database and the lateral tolerance allowed in tracking of the trajectory provided in the flight plan, a vertical profile of lateral navigation margins giving the highest elevations of terrain listed in the terrain elevation database, encountered on the trajectory provided in the flight plan, along an enlarged navigation strip made up of the navigation strip itself, supplemented by right and left lateral margins of maneuver.
- the right and left lateral margins of maneuver are dimensioned so as to delimit sufficient surfaces to contain the traces on the ground of disengagement maneuvers comprising at least a half-turn made, by the aircraft, flat, on the right or on the left of the flight plan path.
- the right and left lateral margins of maneuver are dimensioned so as to delimit sufficient surfaces to contain the traces on the ground of disengagement maneuvers comprising at least a half-turn made, by the aircraft, flat, on the right or on the left of the flight plan trajectory and this, taking into account the local wind.
- the right and left lateral maneuvering margins are dimensioned so as to delimit surfaces sufficient to contain the traces on the ground of disengagement maneuvers comprising at least a half-turn made, by the aircraft, flat, with a radius of imposed turn, to the right or to the left of the flight plan path.
- the right and left lateral maneuvering margins are dimensioned so as to delimit sufficient surfaces to contain the tracks on the ground of disengagement maneuvers comprising at least a half-turn made by the aircraft, with an imposed radius of turn, on the right or on the left of the trajectory planned in the flight plan and this, taking into account the local wind.
- the turning radius imposed for the clearance maneuvers is a minimum turning radius authorized for the aircraft considered.
- the lateral dimensions of the margins of maneuver are a function of the imposed radius of turn and of the positions, relative to the aircraft, of the points of the tracks on the ground of turns with the imposed radius corresponding, for the aircraft, to a cancellation of its speed component perpendicular to the route planned in the flight plan.
- a figure 1 is a top view, of a navigation strip and of the right and left lateral margins according to the invention
- - a figure 2 is a view of a profile vertical navigation supplemented, in accordance with the invention, with a vertical profile of lateral margins
- - a figure 3 illustrates, in horizontal projection, circular trajectories corresponding to flat turns made by the aircraft, at constant speed and roll angle in the absence of local wind
- - a figure 4 illustrates the deformations, in form of cycloid arches, traces on the ground of the circular paths shown in Figure 3 resulting from the presence of a local cross wind.
- FIG. 1 shows, in horizontal projection and seen from above, an aircraft 1 following an effective trajectory 2. Its heading 3 is different from its route (track) 4 along the axis of the projection on the ground of its effective trajectory 2 due of a local crosswind W.
- the planned trajectory is never followed exactly, due to the imprecision of the on-board aircraft location devices, the imprecision of the terrain elevation database used to draw up the maps used for plotting and monitoring the trajectory provided in the flight plan and the tolerance allowed in lateral trajectory tracking.
- the only certainty is that it is above a strip of land known as the navigation strip 5 extending on each side of the trajectory provided for in the plan of flight over a width corresponding to the cumulative sum of the uncertainty of the lateral location of the aircraft with respect to its route, the inaccuracies of the maps used for the layout and monitoring of the trajectory provided for in the flight plan and the tolerance allowed in lateral trajectory tracking. It is important that the safety floor associated with a position of the aircraft 1 running along the trajectory provided for in the flight plan remains above the reliefs and obstacles on the ground identified in the navigation strip.
- FIG. 2 illustrates an example of graphics which can be used on an aircraft dashboard navigation screen to display, in a superimposed manner, the vertical navigation and lateral margins profiles.
- the vertical navigation and lateral margins profiles are represented by the curves 20, 21 of the functions giving the value of the maximum elevation of terrain recorded on a transverse section of the navigation strip alone or with the lateral margins 9 , 10 as a function of the distance traveled on the trajectory provided for in the flight plan.
- the area between the curve 20 of the vertical navigation profile and the distance axis is hatched differently from that between the curves 20 and 21 of the two vertical profiles.
- the curve 20 of the vertical profile of the navigation strip remains always below that 21 of the vertical profile of the lateral margins which is taken from a strip of greater width.
- Different examples of positions 22 to 25 are given for the relative height index of the aircraft.
- the relative height index of the aircraft When the relative height index of the aircraft is in positions 22 or 25, the safety floor of the aircraft is above the reliefs or obstacles on the ground of the overflown portion of the navigation strip but certain reliefs or obstacles on the ground close to the navigation strip laterally are above the safety floor; there are therefore limitations of lateral room for maneuver.
- the relative height index of the aircraft When the relative height index of the aircraft is in positions 23 or 24, the safety floor of the aircraft is above any nearby relief or obstacle on the ground; there is therefore no limitation of the lateral margins of maneuver.
- the terrain elevations are taken from a terrain elevation database as a function of the layout of the trajectory provided for in the flight plan and widths allowed for the navigation strip 5 alone and the navigation strip 5 increased by the lateral margins 9 and 10.
- TAS being the amplitude of the air speed of the aircraft
- g being the acceleration of gravity
- the circles 30, 31 leave traces on the ground 40, 41 in the form of cycloid arches, as shown in FIG. 4.
- the system of parametric equations a track on the ground can be obtained by integrating the system of parametric equations for the air speed of travel on the corresponding circle.
- the system (2) of parametric equations of the speed of the aircraft expressed in a ground coordinate system XY whose Y axis is oriented according to the heading of the aircraft, becomes : fws x being the wind vector ws v
- the initial position condition is
