Definitions

  • the present invention relates to equipment for controlling and guiding the movement of aircraft travelling on the ground on taxi strips for access to and exit from the runway and parking and standing areas of airports.
  • the equipment must also be such that correct operation is ensured even in case of failure and/or during ordinary maintenance operations, and such that it may be applied both at new airports and at airports already in operation, by making use, in the latter case, of auxiliary services and transmission lines which may already be in existence.
  • the present invention provides automatic equipment for controlling and guiding the movement of aircraft travelling on the ground on taxi strips to and from the runways and to and from the standing and parking areas, this equipment comprising in combination illumination devices disposed at predetermined intervals along the longitudinal axis of the taxi strips; light signalling devices spaced equally apart in such a way that each successive pair of signalling devices defines, in the longitudinal direction, consecutive segments of the taxi strip; devices for detecting the transit of aircraft and capable of sending a signal to corresponding means of controlling and displaying the actuation of the sequence of lighting and extinguishing of the illumination and guiding devices and of the light signalling devices of the various segments of the taxi strip, for corresponding permission for or prohibition of the advance of the aircraft along successive segments.
  • the said light signalling devices consist of pairs of lights disposed at the lateral edges of the taxi strip on the transverse axes of the segments and that the said detection devices preferably consist of sensors of the microwave and infrared type and consequently that the said sensors illuminate the respective signalling devices when any detection of the passage of the aircraft has ceased.
  • a further characteristic of the invention consists in the fact that the said control units comprise local control units disposed next to the segments, substation control units disposed inside electrical equipment substations, and central control units disposed in the control tower; in particular, the said substation control units are capable of receiving signals from a central unit and of operating local control units to light and extinguish the axial illumination devices and to extinguish the signalling devices, while the local control units are capable of receiving signals confirming the passage of an aircraft from the sensors and of autonomously causing the lighting of the signalling devices.
  • each unilluminated segment is delimited by illuminated red light signals to prevent the access of an aircraft to the said segment.
  • the automatic equipment may also be used with illumination devices each of which comprises a signalling light and a sensor, each illumination device being capable of operating in this mode, and also as a segment end light, in which case each segment has a minimum length which may be varied as required, and is determined by the lighting of the illumination device with a red light.
  • the central control unit only controls the intersections delimiting sections of taxi strip and that the local and substation control units directly control the segments into which each of the said taxi strip sections, delimited by consecutive nodes, is divided.
  • the map of an airport 1 is normally divided into landing and take-off runways 1a, taxi strips 1b comprising links and intersections 1c, and standing and parking areas 1d.
  • the taxi strips 1b are, according to the invention, ideally divided into segments 2 adjacent to each other and physically delimited by lighting elements whose lighting and extinguishing are monitored and controlled by programmed control units which receive signals from sensors associated with the lighting elements and send lighting or extinguishing commands to local control units which are in communication with a central unit installed in the control tower.
  • each segment 2 (Fig. 2) is provided with illuminating elements 3 disposed at predetermined intervals, as will be more clearly specified subsequently, along the longitudinal axis of the segment 2 which is delimited by two opposite theoretical transverse lines 2a constituting the axis of alignment of stop lights 4 associated with sensors 5 capable of detecting the passage of an aircraft 6 and of lighting the stop lights 4 through the local control unit 11, which in turn sends a confirmation signal to a substation control unit 13 located near the taxi strip in corresponding substations 12 (Fig. 4).
  • the minimum length of a segment 2 is determined on the basis of certain parameters which affect the whole design of the equipment and include the photometric properties of the illuminating elements 3, the characteristic category of authorization for landing, the geometry of the electrical circuits of the light fittings and the dimensions of the aircraft; the power of the lamps and their spacing along the segment, together with the length of the segment itself, will be calculated from these parameters.
  • the axial illuminating elements 3 are connected to the series power supply circuits 8 disposed along the taxi strip 1b at its edges, each pair of illuminating elements 3 formed in this way being connected to isolation transformers 9 in parallel to which are connected local control units 10 in order to implement the lighting and extinguishing commands received from the substation control unit 13.
  • two pairs of stop lights 4 are also installed at each transverse axis of the start and end of a segment 2 near the edge of the taxi strip, these lights also being supplied from the mains 8 through transformers 9, in parallel with which are connected sensors 5 to detect the passage of the aircraft, these sensors also being supplied from the mains 8 through isolation transformers 9.
  • the terminals of the electrical circuits are connected to constant current regulators 13a housed in the electrical substations 12, which in turn are connected to substation control units 13 for connection (Fig. 5) to the central control unit 14 which is located in the control tower and substantially consists of a pair of electronic computers 14a arranged in parallel, a monitoring unit 14b capable of determining the priority of operation between the two computers, a data compression unit 14c and an intermediate register 14d for the temporary storage of signals from and to the substation control units 13, installed in the individual substations 12, which operate at a different rate from the central unit 14.
  • the operating sequence of the equipment is as follows (Fig. 6a): when an aircraft 6a passes through a given segment 2a, all the axial lights 3a of the segment 2a are illuminated to guide the aeroplane and at the same time the red stop lights 4'a, defining the start of segment 2a, are illuminated to prevent any access to the same segment by another aeroplane. During such a phase the axial lights 3b of segment 2b, behind and adjacent to the occupied segment 2a, are extinguished, since the presence of an aeroplane 6, which would be too close to the one in front, is not permitted in this segment.
  • the stop lights 4''a disposed next to the transverse end axis of segment 2a permit free passage, being extinguished, and allow the aeroplane 6a to proceed on its way, guided by the corresponding axial lights 3c which will be lighted.
  • a second aeroplane 6b travelling along the same taxi strip behind the aeroplane 6a would find the axial lights 3e of its segment 2e illuminated and the rear stop lights 4'e and forward stop lights 4''e illuminated with red lights to prevent the advance of the aeroplane 6b to the following segment 2b, which would be immediately adjacent to the segment 2a already occupied by the aeroplane 6a and which, in turn, has axial lights 3b extinguished as stated previously.
  • the substation control unit 13 which, by a dialogue with the central control unit 14, enables the latter to send signals to the local control unit 10 to modify the situation as follows: illumination of the axial lights 3d of segment 2d to allow aeroplane 6a to proceed on its way, on completion of the passage of which in front of the sensors 5'a the situation is further changed as follows (Fig.
  • the equipment according to the invention is completed by a device for the display of the complete ground traffic situation of the airport, which enables the operators to identify on a video screen 15 (Fig. 7) fixed areas 15a for identification of particular aeroplanes, distinguished for example by their own flight numbers, such fixed areas being associated with a broken line 15b or the like to graphically link the identification area 15a with the segment 2 of taxi strip occupied by the aeroplane and represented on the screen within the map of the airport; as the aeroplane moves along the taxi strip to take off or, in the opposite direction, to the parking area 1d, the identification number will occupy successive fixed areas and change its position on the screen.
  • a video screen 15 Fig. 7
  • fixed areas 15a for identification of particular aeroplanes distinguished for example by their own flight numbers, such fixed areas being associated with a broken line 15b or the like to graphically link the identification area 15a with the segment 2 of taxi strip occupied by the aeroplane and represented on the screen within the map of the airport; as the aeroplane moves along the taxi strip to
  • FIG. 8 It is also possible (Fig. 8) to theoretically divide the map of the airport into sections 102 located between two consecutive intersections, known as nodes, 101c, additionally dividing the tasks of the various control units in such a way that the substation control units 13 have the task of guiding the aeroplane in the individual segments 102 until the final sensor 105 indicates that the aeroplane is entering a node 101c, at which point control passes to the central control unit 14, which is informed of the presence or absence of the other segments leading to this particular intersection, and which may establish the order of precedence of access to the intersection or may divert a machine to other segments; with such a configuration it would be possible to make considerable savings of transmission time, since the data traffic relating to the control of the advance of the aircraft 6 in segments 102 would be limited to the substation control units situated near the taxi strips, while only the data concerning the actual position of each aeroplane would be sent to the central control unit (14).
