NOTAM

Abstract: NOTAMs are time- and safety-critical announcements of temporary changes to global flight conditions essential to personnel concerned with flight operations. In this paper we introduce SemNOTAM, a knowledge-based framework that enables fine-grained intelligent semantic filtering and provides a formal, explicit, and machine-readable representation of Digital NOTAMs and associated business rules. Filtering functionalities for time, space, aircraft, user-defined aspects, and any combination thereof are supported. Furthermore, SemNOTAM is designed in such a way that it can be employed in various scenarios, e.g., On-Board briefing or Flight Planning Briefing. Regardless the specific scenario 100% recall is supported.

Abstract: Provided are methods and systems for the automatic assessment and presentation of data on a display device that describes the operational impact on mission critical parameters resulting from a change in a vehicle's mission plan. The change in mission plan may be inputted manually by the vehicle operator but may also be received electronically and automatically over a data up link from an outside authority.

Abstract: A present novel and non-trivial system, module, and method for presenting NOTAM information are disclosed. A plurality of sources may be used for providing navigation data, terrain data, NOTAM data, and object data. After receiving this data, a NOTAM display generating processor may generate a NOTAM image data set as a function of the navigation data, terrain data, NOTAM data, and object data. The NOTAM image data set may be representative of NOTAM information presented in a three-dimensional perspective of a scene outside an aircraft, where NOTAM information may comprise non-textual NOTAM information, textual NOTAM information, or both. After being generated, the NOTAM image data set may be provided to a presentation system where NOTAM information may be presented on at least one tactical display unit such as a head-down display unit and/or a head-up display unit.

Abstract: The Federal Aviation Administration (FAA) Next Generation Air Transportation System (NextGen) system incorporates many updates to aerospace technology including coordination of air traffic management (ATM), flight deck control, and avionics architectures. One such consideration is the need for ontologies. An ontology is a formal naming and definition of the types, properties, and interrelationships of the entities that exist (and persist) for a particular domain. In aviation, an ontology is needed to organize the variables to afford computations, instructions, and the relationships between parameters. For example Triples are used as Universal Resource Identifiers (URIs) in the case of {subject, predicate (verb), object}. The subject and object entities can be connected with the relationship predicate. Together, they are an event such as an ontology coordinating Notice to Airmen (NOTAM) flight weather information. In this paper, we explore the concepts of ontologies for applications to aerospace avionics as motivated by the NextGen and Single European Sky ATM Research (SESAR) standards.
