Abstract

The present application discloses an on-demand, portable mass data storage device useful for navigational planning and other applications. One embodiment comprises a flight planning apparatus having a formatted database and a processor control system which accesses the database in response to user inputs. User inputs are prompted to be coordinated with the formatting of the database to provide for optimal accessing. Particular data records may then be retrieved from the database in response to individualized user inputs, for example, in conjunction with flight planning in which particular approach and other navigational aids must be filtered from a large volume of similar information. In the preferred embodiment, sorting of the information may be done on either a geographic or a named basis. Output of the system comprises information which the user find necessary for the particular planning application. For example, air navigation flight charts may be printed in conjunction with a trip confirmation and an FAA flight plan. Also, ready cross reference between named locations and geographical identification of those named places, such as airway intersections, may be accomplished. Additionally, real time information may be provided through direct phone links. Further, customized cartographic aids may be generated for each user application by review of data in a database and generation of a symbol for particular data records with a corresponding textual identification.

Claims

1. Navigation planning apparatus comprising:

input means for entering selected navigation planning data;

output means for sorting, selecting and providing navigation plan information to a pilot;

storage means for storing navigation-related data in a selected format as a database;

processor means for generating user prompts at said input means to prompt a user to input said navigation planning data in a preselected format and responsive to said input data to sort, select, and access data in said database in storage means to generate said navigation plan information at said output means; and

said input means, data storage means, including said database, and processor means being contained within a common, portable package.

2. The method of claim 1 wherein:

said preselected format of said database includes referencing said navigation information by alphanumeric symbols indicative of airports and radio communication centers and sorting, selecting and providing flight navigation information associated with said airports and radio communication centers.

3. The portable navigational planning apparatus of claim 1 wherein said navigation-related information comprises cartographic, topographic, geographic and navigational aid information and wherein said navigation plan information for output comprises a combination of said cartographic, topographic, geographic and navigational aid information.

4. The portable navigational planning apparatus of claim 1 wherein said navigation-related data comprises at least approach and departure charts associated with a plurality of airports and wherein said processor means prompts a user to input an identification of at least departing and arrival airports, whereby said navigation plan information for output then comprises approach and departure charts associated with said departing and arriving airports.

5. The portable navigational planning apparatus of claim 4 wherein said navigation plan information further includes strip cartographic information particular to a path between said departing and arrival airports.

11. The apparatus of claim 2 wherein said strip information includes cartographic information particular to a path between said origin and said destination.

6. A method for providing flight plan information at remote locations comprising:

storing flight data including at least approach and departure charts as a database in compact, portable storage means in a preselected format;

providing user prompts to prompt the user to input planning data corresponding to said selected format;

sorting, selecting and accessing data in said database said storage means to retrieve selected portions of said flight data in response to said prompted user inputs; and

processing said input planning data in conjunction with retrieved portions of said flight data to provide flight plan information, including approach and departure charts, corresponding to pilot needs.

7. A method for providing navigational information at remote locations including airborne locations comprising:

storing a database comprising selected navigational data in compact, portable storage means in a preselected format;

providing user prompts in conjunction with said portable storage means to prompt the user to input planning data corresponding to said preselected format of said database;

sorting, selecting and accessing data in said database in said storage means to retrieve selected portions of said navigational data in response to said prompted user inputs; and

processing said input data in conjunction with said retrieved portions of said navigational data from said database to provide navigational plan information to a pilot at said remote location.

8. Portable navigational planning apparatus comprising:

compact data storage means for storing flight path and approach chart information in a data base;

user input means associated with said data base for entering planning data and sorting and selecting data in said data base;

output means for providing a user with selectable navigational information from said database;

processor means for providing user prompts to said input means to prompt a user to input selected planning data in a preselected format and responsive to said input data to retrieve at least a predetermined array of flight path and approach chart information; and

means for generating an output display including a cartographic representation of the flight plan and cartographic displays of the appropriate terminal approach charts.

9. Portable navigational planning apparatus comprising:

compact data storage means for storing a data base comprising selected navigational information;

user input means associated with said compact data storage means for entering planning data and for sorting, selecting and accessing data in said database.

output means for providing a user with selectable navigational plan information from said database; and

processor means for providing user prompts to said input means to prompt a user to input selected planning data in a preselected format and responsive to said input data for accessing said data storage means to retrieve at least a predetermined array of navigational information from said database in a selected pattern for output, providing said patterned navigational information at said output means and processing said input information to provide associated information unique to said input data at said output means to a user in conjunction with said navigational information;

said data storage means, including said database, input means, output means and processor means being contained within a common, portable cabinet.

10. The apparatus of claim 9 wherein:

said processor prompted inputs comprise at least origin and destination data; and

said processor is responsive to said origin and destination data to sort and retrieve selected flight navigation charts of said navigational data from said database said data storage means and to generate strip information particular to a path between said origin and said destination at said output means based on navigational information from said database.

12. The portable navigational planning apparatus of claim 9 wherein said selected navigational information comprises cartographic, topographic, geographic and navigational aid information and wherein said patterned navigational information for output comprises a combination of said cartographic, topographic, geographic and navigational aid information.

13. The portable navigational planning apparatus of claim 9 wherein said selected navigational information comprises at least approach and departure charts associated with a plurality of geographic points and wherein said processor means prompts a user to input an identification of at least departing and arrival airports, whereby said selected pattern of navigational information for output then comprises approach and departure charts associated with said departing and arriving airports.

14. The portable navigational planning apparatus claim 9 wherein said selected navigational information is provided, at least in part, by said output means in a cartographic format.

15. The portable navigational planning apparatus of claim 9 wherein said selected navigational information is provided at least in part, by said output means, in a cartographic format representing en route geography.
