Definitions

  • the invention relates generally to apparatus for, and methods of, warning aircraft of obstacles.
  • tall ships can be a danger to aircraft, particularly in regions where there is significant offshore industry, such as oil and gas industry.
  • Ships involved in industrial activity can have height dimensions which present danger to aircraft, due to the presence of cranes and other tall structures (such as parts of oil rigs) carried on such ships. Collisions between ships can be avoided, or least reduced, by use of commercial Automatic Identification Systems (AISs).
  • AISs Automatic Identification Systems
  • a ship carrying an AIS transponder emits a signal on a dedicated VHF channel, the signal containing information corresponding to the ship's position, speed, direction and identity.
  • the AIS transponder also receives such signals from other ships. Trajectories of ships can therefore be compared and suitable action taken to avoid collisions.
  • a first aspect of the present invention provides apparatus for warning an aircraft of an obstacle on the earth's surface, the apparatus comprising a warning system arranged to:
  • the invention provides the advantage that an obstacle may be assessed as a potential danger to aircraft using only information corresponding to the obstacle's position and identity; reception of information corresponding to the obstacle's height is not necessary since the obstacle's height is obtained from a database using the obstacle's identity. Since a warning signal is generated only if the aircraft's altitude is comparable to the obstacle's height, and not simply if the obstacle lies on the aircraft horizontal trajectory, the incidence of false alarms is reduced compared to prior art methods which only utilise the obstacle's position in order to decide whether the obstacle presents a danger to aircraft.
  • the warning system is arranged to receive third information corresponding to the obstacle's speed and direction and to use the first and third information and the aircraft' horizontal trajectory to calculate whether the aircraft and the obstacle will coincide in horizontal position at a coincidence point, and to generate a warning signal if the aircraft and obstacle are calculated so to coincide and the difference between the height dimension of the obstacle and the altitude of the aircraft at the coincidence point is less than a pre-determined value.
  • This provides for additional assessment of the obstacle as a danger to aircraft by assessing whether it will coincide with the aircraft in horizontal position.
  • the warning system is preferably arranged to derive the first information, or as the case may be, the first and third information, from an Automatic Identification System (AIS) signal.
  • AISs are commercially available and are used on ships to provide position, direction, speed and identity information primarily to other ships, but also to aircraft.
  • a commercial AIS signal may be used without modification to warn aircraft of ships that may present danger due to their heights, without a high rate of false alarms, even though an AIS signal does not include any information about the height of ship.
  • the apparatus may comprise a position receiver arranged to receive AIS signals and to pass the AIS signals to the warning system.
  • the storage means is comprised within the warning system.
  • a second aspect of the invention provides a method of warning an aircraft of an obstacle on the earth's surface, the method comprising the steps of:
  • the method further comprises the steps of receiving third information corresponding to the obstacle's speed and direction, and using the first and third information and the aircraft's horizontal trajectory to calculate whether the aircraft and the obstacle will coincide at a horizontal position at a coincidence point, and generating a warning signal if the aircraft and obstacle are calculated so to coincide at the coincidence point and the difference between the height dimension of the obstacle and the altitude of the aircraft at the coincidence point is less than a pre-determined value.
  • the first information may be conveniently derived from an AIS signal.
  • FIG. 1 shows an apparatus of the invention indicated generally by 10 and comprising a ship position receiver 12, storage means 14 storing a database of ship identities and corresponding height data, and a warning sytem 16.
  • the warning system 16 is a standard commercial collision warning system, for example a Helicopter Terrain Avoidance and Warning System (HTAWS).
  • a ship 20 comprises a commercial Automatic Identification System (AIS) transponder (not shown), which emits an AIS signal 22 on a dedicated channel such as a VHF channel.
  • the AIS signal 22 comprises information regarding the position, speed, direction and identity of the ship 22.
  • the apparatus 10 is carried on an aircraft (not shown).
  • the ship position receiver 12 receives the AIS signal 22 and passes a corresponding signal to the warning system 10.
  • the warning system 16 also receives information corresponding to the altitude of the aircraft, and its horizontal position (e.g. latitude and longitude) as a function of time.
  • an aircraft 50 fitted with the apparatus 10 of Figure 1 and having a horizontal trajectory 52 receives a respective AIS signal from each of ships 54, 56.
  • the ship 54 does not lie on the horizontal trajectory 52 and therefore no warning signal is generated in respect of the ships 54.
  • the ship 56 does lie on the horizontal trajectory 52.
  • the warning system uses the identity of the ship 56 obtained from the AIS signal to look up the height dimension of the ship 56 using the database held in the storage means 14. The height dimension of the ship 56 is then compared to the altitude of the aircraft 50 and a warning is generated if the altitude of the aircraft 50 does not exceed the height dimension of the ship 56 by more than a pre-determined value.
  • Figures 3 and 4 illustrate how a warning may be generated based on the trajectory of a ship in addition to its height.
  • An aircraft 60 fitted with the apparatus 10 has a horizontal trajectory 62 and receives respective AIS signals from ships 64, 66.
  • the warning system 16 of the apparatus is arranged to assess the trajectories of the ships 64, 66 using the respective AIS signal of each ship, and to compare the trajectories to the horizontal trajectory 62 of the aircraft 60.
  • the warning system 10 is arranged to establish whether the horizontal trajectory 62 of the aircraft 60 intersects the trajectory of either ship 64, 66, and whether the aircraft 60 will intercept either ship 64, 66 based on their speeds and the speed of the aircraft 60.
  • the trajectory and speed of ship 64 are such that the ship 64 and aircraft 60 will coincide.
  • the warning system 16 of the apparatus 10 therefore generates a warning signal provided the altitude of the aircraft 62 does not exceed the height of the ship 64 by more than a pre-determined value. In such a case the aircraft 60 may make an avoiding manoevre 63 to avoid collision with the ship 64.
  • the aircraft 60 and ship 66 will not coincide at a particular horizontal position (e.g. a particular latitude and longitude) and therefore no warning signal is generated in relation to the ship 66.
