New Computer Monitors Aircraft Network Traffic for Cyber ThreatsVIDEO ON THE TOPIC: HOW MANY SUBJECTS IN AME - HOW MANY SUBJECTS IN AIRCRAFT MAINTENANCE ENGINEER -- AVIATION OFFICIAL
The present invention relates to an aviation, terrain, air traffic and weather display system that provides information for preflight and inflight use by pilots. In particular, the invention uses a terrain database, an aviation map database, a weather database, an airplane specific database, an air traffic control database and a route database to display a flight path over a given terrain while combining weather data e. If that decision is positive, they must then determine the safety of flying to a given destination airport or along a preplanned route.
Presently, the National Weather Service NWS , Federal Aviation Administration FAA and other government agencies assist pilots by providing sky data including wind direction and speed, weather conditions such as rain and other relevant data. Often this information is in cryptic form and is difficult for beginning pilots to understand.
This information must then be applied in the context of a multitude of regulations and aircraft performance parameters, making this a formidable task. Moreover, experienced pilots still often find the information cryptic and find it difficult to retrieve and assimilate specific data relevant to their flight from the large amount available. Confounding the situation further, commercial flight operators have their own unique regulations and restrictions supplementing federal aviation regulations which must be recognized and adhered to by their pilots.
Some systems were developed to automate the delivery of weather information to pilots. For example, U. The system receives weather information from a plurality of weather reporting organizations including the NWS, FAA and others. The system then converts the weather information into cross sections for preflight and inflight use. The system provides pilots with a representation of all the multidimensional space around an airport.
This includes weather, air traffic and spatial relationships of the aircraft with respect to the airport and the ground level. While these patents and other conventional products can provide some level of automation to the weather reporting, these systems do not take into account the special flight rules that are dictated for airports and airspace and specific flight parameters that are unique from one aircraft and one trip to the next.
SUMMARY The invention solves the identified problems by providing a computer system that displays terrain, weather, air traffic and aviation information. The system can display a flight path over a given terrain while combining aviation map data e. Of course, the pilot makes the decision whether to accept the system's suggestions many of whose parameters are controlled by the pilot and whether to query the system to provide additional options.
This information is very important for preflight and inflight planning. This information is combined with information from the other databases to be used for preflight and inflight planning. The air traffic database provides information on aircraft type, position, speed, direction and predicted position that are in the area of the designated flight.
Combined with information from the other databases, this can be used for inflight planning arid collision avoidance. The pilot can also visualize which flying variables e. This provides improved information to the pilot so that he can make his decision whether to make to flight or whether to choose his intended route or destination.
With this improved information, the pilot will make safe and informed decisions about flying. Figure 2 depicts a memory structure for storing program and data in the computer system of Figure 1;.

Figure 9 depicts an aspect of the invention for retrieving and updating the air traffic database. Those skilled in the art will appreciate that various changes and modifications can be made while remaining within the scope of the claims. Figure 1 depicts a computer system 10 according to an embodiment of the invention.
The computer system includes a processor CPU 12 coupled to a bus The memory is configured to store programs and data necessary for the invention, as described below. A number of interfaces 22, 24, 25, 26 are provided for coupling to a user interface.
The user interface includes a display 30 a keyboard 32 and an input device The input device 34 can be a mouse, touchscreen, joystick, flight pedals and yoke, or other conventional input device. The communications interface is designed to retrieve and translate information from these sources.
Of course, additional or alternative computer elements can be employed, as known in the art. In an in-flight system, an interface 27 is provided for a global positioning receiver GPS 29 in order to provide aircraft position information to the computer system An interface 25 is created for any onboard aircraft sensors such as wind direction and speed, outside air temperature, aircraft attitude and air speed in order to further supplement navigation and weather information to the computer system Weather and air traffic data reside on a server and the information is sent to transmission stations for dissemination either via the Internet or another communications medium such as microwave or radio.
In the in-flight system, the communication interface 28 may be a wireless interface that receives weather and air traffic updates from ground stations. As the aircraft moves through space, the computer uses GPS position updates to display the new x, y, z position of the aircraft in relation to the terrain, other air traffic, associated weather, and aviation data. As new weather and air traffic data are received, the computer system displays the aircraft and local traffic at the appropriate positions with the appropriate new surrounding weather conditions.
The pilot can look ahead and behind as necessary to make flight decisions. Figure 2 depicts a memory 40 structure for storing program and data in the computer system 10 of Figure 1. The memory 40 is divided into three primary components: a user interface system 42, database system 44 and communication system The user interface system 42 includes routines for receiving information from the user and for providing information to the user.
Initialization routine 48 provides a function that initializes the computer system 10 on power up and presents the user with a start-up display. A user input routine 50 is configured to receive commands from the user via the user interface and to conform the commands to applicable computer instructions. For example, if the user instructs the computer system 10 to display an alternate image, the user input element instructs the processor 12 to execute such a command.
A user output routine 52 is configured to provide the user with an output from the computer system For example, a display will provide the user with a selected alternate image. Moreover, the output routine can provide additional user stimulus such as force feedback or spatialized or nonspatialized auditory alarms to alert the pilot to certain conditions such as turbulence, icing, high velocity winds or an impending collision with terrain or another aircraf.
The database system 44 includes databases for storing the information related to the invention. Figures 3A-F depicts the database system in greater detail. Figure 3A depicts the terrain database 54 that stores data relating to the ground terrain. The database stores latitude, longitude and elevation for a predefined area. A number of cells are stored in the memory 16, 18 and 20 and additional cells can be added and updated via the CDROM 20 or communication interface Figure 3B depicts the map database 56 that stores aviation map features.
Airspace information is provided including: class A, B, C, D, E, G airspace locations and altitudes; prohibited airspace, restricted airspace, warning areas, military operation areas and alert areas locations, altitudes and times of active status; parachute jumping, ultralight, and glider area locations; and military training routes locations, altitudes and times of operation. Regarding obstacles, location and height information is important. Information about navigational aids' locations, frequencies and types is provided.
For instrument flight, specific information is important such as standard departures, standard terminal arrivals and instrument approaches including: landing patterns, published headings, altitudes, and fixes and their locations , approach type, decision height DH or minimum decent altitude MDA , aircraft category specific data DHs, MDAs, minimum visibility and ceiling , required climb rates and decent profiles and times to final approach fix.
These data may also be customized to reflect commercial operator specific minimums and requirements for landing, takeoff or alternate destinations. For pre-flight and in-flight planning, airway location is provided including names and intersections as well as landmark types, names, locations and elevations.
This map database provides the pilot with information to make pre-flight and in-flight planning. Figure 3C depicts the weather database 58 that stores weather information based on latitude, longitude and altitude. Some of the weather characteristics are: surface observations; composite moisture stability data; wind shear reports and forecasts; icing forecasts; turbulence reports; pilot reports; constant pressure chart data; volcanic ash forecast and dispersion data; surface analysis data; radar summary data; significant weather prognostic data; and satellite imagery e.
This database can be populated by any future reporting or forecasting data products and translated into designated shapes or icons and placed by geospecific coordinates in the 3D world display. Figure 3D depicts the aircraft database 60 that stores aircraft specific parameters for various aircraft.
For each type of aircraft, various parameters are stored including: takeoff performance and distance for different configurations and departures; landing performance and ground roll for different configurations and arrival profiles; cross-wind limits; weight and balance; cruise speed; service ceiling; rate of climb; angle of climb; stall speed; engine out glide path, speed and distance; fuel capacity; gas consumption; and other parameters.
This information assists the computer system 10 and the pilot in making pre-flight and in-flight planning. For example, by using the ground wind information from the weather database and the runway orientation from the map database, the computer can calculate the cross-wind component of the current wind for a particular runway and inform the pilot whether it is within the allowed parameters for the aircraft. Figure 3E depicts the route database 62 that stores information specified by the user including flight path information.
This database is slightly different than the others because it is intended to be modified extensively by the user. For example, the user can input, retrieve and modify flight path parameters.
Additionally, for in-flight use, the route and weather is modified by the GPS position information and aircraft sensors via interfaces 27 and Figure 3F depicts the traffic database that stores specific parameters associated with other aircraft flying in the area of the pilot. For each aircraft, various parameters such as position x, y, z , speed, reported flight route and type of aircraft are stored. The information assists the computer system 10 and the pilot in displaying local air traffic conditions and allows prediction of flight paths from current position and speed parameters of other aircraft in the air traffic database and of the pilot's aircraft from the route database GPS and planned route to identify potential collisions.
Figure 4 is a functional block diagram according to an embodiment of the invention. A fusion module is employed to identify and retrieve information from the database system. Figures 5A-H depict a user display interface according to an embodiment of the invention.
Figure 5A depicts a cockpit view while flying in the San Francisco bay area. An altitude indicator is provided along the left side of the display window 5A-1 and a heading indicator along to the top side of the display window 5A For example, runways are shaded with green overlay for distances calculated to be less than or equal to runway length minus 50 feet, shaded with yellow overlay for distances calculated to be greater than runway length minus 50 feet and less than or equal to runway length, and shaded with red for distances calculated to be greater than the runway length.
The display window 5A-1 is the 3D portion of a general user display containing data presented as a combination of 2D and 3D display techniques. The display is provided on the user's display 30, but can also be implemented through software running on a dedicated hardware device such as a personal computer PC , or on a web page running on a PC. The user has control of all the display elements so any combination of parameters may be turned on or off.
Three display profiles are created covering the takeoff, en route and landing or approach sequences of a flight for usability. Additionally, extensive use of an event trigger function, which allows an event to be triggered when the cursor is over an object, allows the user to selectively drill down on information on the 2D or 3D display by providing supplemental textual information right at the cursor or in a text box in the display window 5A Within the display window 5A-1 is the terrain information such as mountains and water.
Adjacent to the display window is weather information 5A-3 such as visibility, dewpoint spread, a ball bearing-like representation of temperature and wind, and other information. This weather information can also be overlaid on the display window 5A-1 or an icon can be provided to open and close the weather information.
Figure 5B depicts a satellite view of the aircraft, terrain and weather conditions. As shown, the aircraft is heading toward a group of clouds that are identified as gray areas.
