A judicious and carefully considered assessment by the appropriate Designated Approving Authority (DAA) that an information system meets the minimum requirements of applicable security directives, given its proposed systemic capabilities and functions, and that any residual risks are low.

Attribute that allows the ability to identify, verify, and trace system entities as well as changes in their status. This allows for authentication and non-repudiation.

See Authorization

The function to obtain information pertaining to the condition of a defined volume of airspace

The function to receive a collection of quantitative data compiled from daily operational activities

The function to obtain flight data, which includes, but is not limited to flight plans and amendments, reported altitude, track position, velocity, and time estimates

The function of receiving information referenced to unique earth-based geographic coordinates.

The function of receiving weather data from the ground based weather sensors via electronic or printed media; converting from one form to another to enable the transmission of the data through electronic means. Provide the weather data obtained from ground based weather sensors to the service providers and airspace users via electronic or printed media.

Receive the weather data from the ground based weather sensors via electronic or printed media; convert from one form to another to enable the transmission of the data through electronic means. Provide the weather data obtained from ground based weather sensors to the service providers and airspace users via electronic or printed media.

The function to obtain information about an object

The function to obtain the actual planned position of an object (aircraft).

The function that transmits a signal intended to trigger a transponder consultation of sources of information, to discover or determine the existence, presence, or fact of any consultation of sources of information pertaining to frequency of electrical energy above the audio range, the relative association of two sets of data; e.g., positional agreement between radar and the computer predicted track position, or to disperse throughout any consultation of sources of information pertaining to frequency of electrical energy above the audio range that is capable of being radiated into space.

The function to obtain information pertaining to the condition of a specific element of equipment or a group of elements comprising a complex whole

The function that judges and decides with soundness, prudence, and intelligence; to explain or tell the meaning of and present in understandable terms; to detect a function provided by lights, visual markers, et al; to disperse throughout; any consultation of sources of information pertaining to frequency of electrical energy above the audio range that is capable of being radiated into space at an airport to the pilot to help guide along a safe path to touchdown and beyond.

The point of service delivery of a non-NAS Architecture Node from which Administrative Services are delivered

The logical and contextual entity that houses the systems that are related to or responsible for administration

The FAA equipment that is not operated and maintained by the ATO that provides administrative services and data in support of the air navigation service mission.

A Non-Developmental Item (NDI) automation, communications, training, maintenance, installation, transition, and procedures development support acquisition. It will provide a Flight Data Processing (FDP) capability fully integrated with Surveillance Data Processing (SDP). The SDP will be capable of processing primary and secondary radar, Automatic Dependent Surveillance (ADS, both Addressable: ADS-A and Broadcast: ADS-B), Controller Pilot Data Link Communications (CPDLC) position reports, and relayed High Frequency (HF) radio voice pilot position reports from an HF radio operator employed by a communications service provider under contract to the FAA. ATOP will support radar and non-radar procedural separation, tracking clearances issued via CPDLC or messages through the HF radio service provider, conflict detection/prediction capabilities through the use of controller tools (Conflict Alert and Minimum Safe Altitude Warning for radar airspace and Conflict Probe for non-radar procedural separation applications), and fully automated coordination via Air traffic services Inter-facility Data Communications System (AIDCS) with AIDCS equipped adjacent Flight Information Regions (FIRs) . The ATOP inter-facility data communications system will be capable of supporting the International Civil Aviation Organization (ICAO) air traffic services message set. ATOP supports operations in which the information and primary capabilities required for the controller to maintain situational awareness and provide procedural separation services are available on the display (rather than paper flight strips).

The logical and contextual entity that houses the system functions and data necessary to provide the necessary weather information for flight.

Noun: A combination of sensors and anemometer equipment used to detect meteorological conditions such as temperature, dew point, wind speed and direction, visibility, sky condition, cloud heights and types, precipitation, and barometric pressure.

The logical and contextual entity that houses the systems and functions that can detect meteorological conditions using radio waves.
