Definitions

  • the TAWS is operable to acquire selected flight-related information from various aircraft systems and to obtain terrain information for topological features surrounding the aircraft.
  • the TAWS is configured to process the flight-related information and the terrain information to determine if a potential safety condition due to terrain proximity is present. If a terrain proximity hazard is determined to exist, the TAWS provides a flight crew with a suitable audible and/or visual warning that timely alerts the flight crew regarding the detected terrain hazard.
  • TAWS are generally effective in enhancing the safety of flight
  • drawbacks nevertheless exist.
  • the aircraft may be intentionally operated relatively close to the surrounding terrain so that numerous terrain proximity messages are generated by the TAWS and communicated to the flight crew.
  • the flight crew is generally capable of maintaining sufficient visual contact with the surrounding terrain so that the aircraft may be safely navigated along a desired flight path without assistance from the TAWS.
  • the numerous terrain proximity messages may constitute a nuisance that may distract the flight crew from other important flight-related tasks.
  • the flight crew may deactivate the TAWS so that the nuisance messages are suppressed.
  • An obvious shortcoming associated with deactivation of the TAWS is that an undesired terrain incursion may nevertheless occur during a temporary period of flight crew inattention to the visual monitoring of surrounding terrain.
  • a ground proximity warning system for a flight vehicle includes a processor that is configured to generate a look-ahead envelope that defines a region extending outwardly from the vehicle, such as an aircraft or surface or subsurface vessel, and to generate a terrain proximity message when the defined region intersects a terrain feature.
  • An interface device is coupled to the processor that is operable to configure the system in a first operating mode wherein the generated terrain proximity message is selectively suppressed, and a second operating mode wherein the terrain proximity message is not suppressed.
  • FIG. 1 is a block diagrammatic view of a system for selectively altering a ground proximity alert level for an aircraft, according to an embodiment of the invention
  • FIG. 2 is a graphical illustration of an aircraft having the system of FIG. 1 that is used to further describe the operation of the system;
  • FIG. 3 is another graphical illustration of an aircraft having the system of FIG. 1 that is used to further describe the operation of the system;
  • FIG. 4 is a flowchart that describes a method for selectively altering a ground proximity alert level for an aircraft, according to another embodiment of the invention.

  • the system 10 includes a look-ahead warning generator 12 that is operable to receive sensor data and terrain information and to process the sensor data and terrain information to generate aural and/or visual indications related to the proximity of the aircraft to the surrounding terrain.
  • the look ahead warning generator 12 will be discussed in greater detail below.
  • the look-ahead warning generator 12 is operably coupled to a plurality of sensors 14 that are configured to provide selected data inputs to the look-ahead warning generator 12 .
  • the sensors 14 may include an altitude sensor 16 and an airspeed sensor 18 that are configured to provide altitude and airspeed information, respectively, to the look-ahead warning generator 12 .
  • the altitude sensor 16 and the airspeed sensor 18 may be operably coupled to an air data computer (ADC) that receives static pressure, total pressure and total air temperature information from suitable sensors positioned on the aircraft, and processes the values to generate a true airspeed, a Mach number, or other desirable operational values.
  • ADC air data computer
  • the sensors 14 may also include various navigational sensors, which may include a position sensor 20 , a track sensor 22 and a heading sensor 24 that cooperatively provide navigational information to the look-ahead warning generator 12 .
  • the navigational sensors may include a suitably configured receiver that is operable to detect navigational signals communicated to the aircraft.
  • the navigational sensors may include a global positioning system (GPS) receiver that is operable to receive navigational information from a satellite-based navigational system and process the navigational information to generate positional, track and heading values for the aircraft.
  • GPS global positioning system
  • the navigational sensors may include a receiver that is configured to receive navigational information relative to a ground-based system of navigational stations, such as the known VHF Omni Range (VOR) stations, non-directional beacons (NDB) and long-range navigation (LORAN) stations.
  • VOR VHF Omni Range
  • NDB non-directional beacons
  • LORAN long-range navigation
  • the navigational sensors may also include other known devices that provide navigational information to the look-ahead generator 12 based upon the dynamic behavior of the aircraft.

  • INS inertial navigation system
  • FMCS flight management computer system
  • the system 10 also includes a memory device 26 that is suitably configured to store a searchable database that contains data pertaining to anticipated flight operations for the aircraft.
  • the memory device 26 may include data that describes various geographical features and elevations of the terrain for an anticipated flight route.
  • the memory device 26 may further include data pertaining to various man-made geographical features, such as locations, elevations and runway information for various landing sites along the anticipated flight route.
  • the memory device 26 may further include data regarding various navigational aids (NAVAIDS) and air route intersections that may be used along the anticipated flight route, and may further include one or more “waypoint” locations, as are generally known in connection with GPS-based systems.
  • NAVAIDS navigational aids
  • air route intersections that may be used along the anticipated flight route, and may further include one or more “waypoint” locations, as are generally known in connection with GPS-based systems.
  • the generator 12 includes a processor 28 that is generally operable to receive programmed instructions and data, and to process the data according to the received instructions.
  • the processor 28 may be an integral portion of the generator 12 , or it may be remotely positioned from the generator 12 and suitably and operably interconnected with the generator 12 .
  • the generator 12 receives flight-related information from the foregoing sensors 14 and also receives geographical information from the memory device 26 . Based upon the received flight-related and geographical information, the generator 12 is operable to generate a look-ahead envelope that represents an outward extension from the aircraft that may be used to generate a terrain proximity message when the look-ahead envelope intersects a terrain feature.
  • the look-ahead envelope may be further divided into a terrain advisory envelope and a terrain warning envelope that permit different proximity alarm states to be generated by the look-ahead warning generator 12 .
  • the generator 12 provides an advisory level message to a flight crew in the aircraft. If the warning envelope intersects a terrain feature, however, a warning level message is communicated to the flight crew that generally provides an audible and a visual warning to the flight crew.
  • the look-ahead envelope may include still other envelope configurations that provide still other messages when a terrain feature intersects the envelope.
  • the look-ahead envelope may be configured to have any desired shape and to extend outwardly in longitudinal and lateral directions to any desired distance. Suitable look ahead envelopes are disclosed in detail in U.S. Pat. No. 5,839,080, to Muller, et al., and entitled “Terrain Awareness System”, which patent is commonly owned with the present application, and is incorporated herein by reference.

  • the display device 30 may include an illumination device that is positioned to be within a field of view of the flight crew that illuminates when a suitable signal is received from the look ahead warning generator 12 .
  • the aural warning generator 32 may also include a speech synthesizer that is configured to generate an artificial representation of a human voice to communicate terrain proximity messages having speech-based content to the flight crew.
  • the aural warning generator 32 may be configured to emit one or more audible tones at predetermined audio frequencies that are recognizable as corresponding to a selected terrain proximity condition.
  • the system 10 also includes an interface device 34 that is operable to permit the flight crew to select a first operating mode, and a second operating mode for the system 10 .
  • the flight crew may selectively suppress terrain proximity messages generated by the look-ahead warning generator 12 , so that an aural terrain proximity message is suppressed while a visual terrain proximity message that is displayable on the display device 30 is presented to the flight crew.
  • the aural terrain proximity message may be presented, while the visual terrain proximity message is suppressed.
  • the aural terrain proximity message and the visual terrain proximity message may be simultaneously suppressed when the first operating mode is selected.
  • Suppression of the terrain proximity messages in the first operating mode thus advantageously allows the flight crew to selectively suppress nuisance messages that may otherwise interfere with the operation of the aircraft.
  • nuisance messages may otherwise interfere with the operation of the aircraft.
  • the corresponding terrain proximity warnings may constitute a significant distraction to the flight crew.
  • terrain proximity messages may be selectively suppressed by means of the interface device 34 , it is understood that the suppression of the terrain proximity messages may be overridden by the look ahead warning generator 12 in cases where the surrounding terrain is determined to constitute a threat to the safety of flight of the aircraft.
  • the terrain proximity massages are not suppressed, and all messages are presented to the flight crew.
  • the interface device 34 may be manually actuated by the flight crew to suppress terrain proximity messages generated by the generator 12 , or it may actuated by other means.
  • the interface device 34 may include a speech recognition device that is operable to receive verbal commands from the flight crew to configure the system 10 in one of the first operating mode and the second operating mode.
  • FIG. 2 is a graphical top view illustration of an aircraft 40 having the system 10 of FIG. 1 that will be used to further describe the operation of the system 10 .
  • the aircraft 40 shown in FIG. 2 navigates within a terrain structure 42 that includes first terrain features 44 positioned on a side and apart from the aircraft 40 , and second terrain features 46 positioned on an opposing side of the aircraft 40 and apart from the aircraft 40 .
  • the first terrain features 44 further include terrain contours 44 a, 44 b and 44 c that represent relatively constant terrain elevations.
  • the terrain contour 44 a represents a terrain elevation that is less than the terrain elevation represented by terrain contour 44 c.
  • the terrain contour 44 b generally corresponds to a terrain elevation that is intermediate between the elevations represented by the terrain contours 44 a and 44 c.
  • the first terrain features 44 constitute a geographical structure having a generally upwardly increasing elevational gradient.
  • the second terrain features 46 similarly include terrain contours 46 a, 46 b and 46 c that also represent relatively constant terrain elevations.
  • the terrain contour 46 a represents a terrain elevation that is less than the terrain elevation represented by terrain contour 46 c
  • the terrain contour 46 b corresponds to a terrain elevation that is intermediate between the elevations represented by the terrain contours 46 a and 46 c, so that the second terrain features 46 also constitute a geographical structure having a generally upwardly increasing elevational gradient.
  • a three-dimensional look-ahead envelope 50 that is generated by the look ahead warning generator 12 ( FIG. 1 ) represents a volume that extends forwardly, laterally, and downwardly away from the aircraft 40 .
  • the look-ahead envelope 50 intersects the second terrain features 46 . Accordingly, if the system 10 in the aircraft 40 is operated in the second operational mode, a terrain proximity message will be generated by the system 10 that alerts the flight crew to the possibility of a terrain incursion if the present ground track 48 is maintained.
  • the system 10 determines if alternative flight paths are available to the aircraft 40 that will avoid a terrain incursion. For example, if the aircraft 40 is steered to proceed along a first flight path 52 , the aircraft 40 will avoid the terrain incursion. Similarly, the aircraft 40 may avoid the terrain incursion if the aircraft 40 is steered to proceed along a second flight path 54 , or even a third flight path 56 .
  • the determination of an alternative flight path typically also includes a determination if the aircraft 40 can execute a suitable aircraft bank angle, possesses a suitable rate of climb and/or thrust, or other pertinent performance characteristics before a flight path is accepted as a suitable alternative flight path.
  • FIG. 2 illustrates only three flight paths, it is understood that as few as one, or alternately, a plurality of flight paths may be processed by the look ahead warning generator 12 to determine if the flight paths are suitable alternative flight paths.
  • the aircraft 40 having the system 10 is shown navigating within a terrain structure 60 that further includes terrain contours 60 a, 60 b and 60 c that represent relatively constant terrain elevations, with the terrain contour 60 a corresponding to an elevation that is less than a terrain elevation represented by the contour 60 c.
  • the terrain contour 60 b generally corresponds to an elevation that is intermediate between the elevations represented by the contours 60 a and 60 c, so that the terrain structure has a generally upwardly increasing elevational gradient.
  • the look ahead envelope 50 intersects the terrain structure 60 , and the system 10 accordingly determines if an alternative flight path is available to the aircraft that would avoid a terrain incursion.
  • the look ahead warning generator 12 within the system 10 may select the flight paths 62 , 64 and 66 and determine if, while operating in the first operating mode, at least one of the flight paths 62 , 64 and 66 will avoid a terrain incursion. If it is determined that none of the flight paths 62 , 64 and 66 are suitable, then the first operating mode is overridden, and a terrain proximity message is communicated to the flight crew. Alternately, if at least one of the flight paths 62 , 64 and 66 are suitable alternative flight paths, the terrain proximity message is suppressed.
  • FIG. 3 illustrates three flight paths, it is understood that as few as one, or alternately, a plurality of flight paths may be processed by the look ahead warning generator 12 to determine if the flight paths are suitable alternative flight paths.
  • FIG. 4 is a flowchart that will be used to describe a method 70 for selectively altering a ground proximity warning message for an aircraft, according to another embodiment of the invention.
  • the ground proximity warning system is configured in a selected operating mode.
  • the selected operating mode is operable to suppress a ground proximity message generated by the system, as will be discussed in more detail below.
  • a suitably configured look ahead envelope is constructed by accessing terrain data stored in the memory device 26 and by receiving navigational information from the sensors 14 , as shown in FIG. 1 .
  • an intersection of the look ahead envelope with a surrounding terrain feature is detected.
  • the envelope may be further subdivided into an advisory envelope and a terrain-warning envelope that permit different proximity alarm states to be generated.
  • the system 10 of FIG. 1 generates at least one suitable alternate flight path for the aircraft that may avoid the intersection. If the at least one alternate flight path has an advisory or warning envelope that avoids the intersection, as shown at block 80 , then the terrain proximity message is suppressed (operational mode 1), as shown at block 82 . Alternately, if it is determined at block 80 that no alternate flight path exists, the method 70 overrides the selected operating mode and communicates the terrain proximity message to the flight crew.
