Abstract: Dynamic partitioning of a search space of queries is implemented for flexible, heuristic database querying. Search space partitioning refers to dividing the search space for a submitted query into smaller parts by augmenting the queries to append thereto an additional predicate comprising a dynamic partition key and a value(s) selected based on heuristics (e.g., recency and/or relevancy of the value(s)). A plurality of candidate augmentations of the query and corresponding query plans are generated and evaluated based on additional heuristics to determine which can be executed to yield the best results in terms of result quality and latency. This query plan is selected and executed for retrieval of results that satisfy the query, with pagination utilized for presentation of the results. The procedure of generating candidate query plans, selecting one of the candidates for execution, and paginating results is repeated until a search termination criterion is satisfied.

Abstract: A system for an airborne platform includes a display device and a processing circuit communicably coupled to the display device. The display device is configured to provide a display. The processing circuit is configured to determine one or more performance characteristics of the aircraft, a predicted landing path including a predicted touch down point of a runway, and whether the predicted touch down point is within a recommended touch down zone. The processing circuit is further configured to generate a three-dimensional display providing a visual representation of the aircraft, the runway, and the predicted landing path. The visual representation of the predicted landing path is provided as a first color in response to determining the touch down point is within the recommended touch down zone and the visual representation of the predicted landing path is provided as a second color in response to determining the touch down point is not within the recommended touch down zone.
