C.1.25 Information. Data that (1) has been verified to be accurate and timely, (2) is specific and organized for a purpose, (3) is presented within a context that gives it meaning and relevance, and which (4) leads to an increase in understanding and decrease in uncertainty. The value of information lies solely in its ability to affect a behavior, decision, or outcome.
C.1.26 Meteorol ogical Data. A representation of meteorological observations, forecasts, and environmental model output in a formalized manner suitable for communication, interpretation, or processing.
C.1.27 Meteorological Information (METI). Information resulting from the assembly, analysis, and formatting of weather data.
C.1.28 Near-Real-Time. Cur rent or immediate information; responding to events or inputs as fast as possible, or as they happen.
C.1.29 Non-FAA FIS. A c ommercial data link service providing aviation weather and operational information to customers.
C.1.30 Non-FAA FI S Provider. An organization that operates a commercial data link service providing aviation weather and operational information independent of a vendor service agreement with the FAA.
C.1.31 Product. Data set or data set series of METI/AI produced and displayed in accordance with a published or defined format in a manner usable and interpretable to a pilot.
C.1.32 Product Latency. An element of data age. The tot al latency of METI/AI messages includes the total time between the actual occurrence of the phenomenon, the data collection, processing, transmittal, and the display or application of the information on the flight deck. The amount of total latency may limit the use or application of the information.
C.1.33 Request-Repl y Mode. Two-way communication in which AI or METI is transmitted to a requestor in response to a specific request.
C.1.34 Special Activity Airspace (SAA). Any airspace with defined dimensions within the National Airspace System (NAS) wherein limitations may be imposed upon aircraft operations. This airspace may be restricted areas, prohibited areas, Military Operations Areas (MOA), ATC-assigned airspace, and any other designated airspace areas. The dimensions of this airspace are programmed into the User Request Evaluation Tool (URET) and can be designated as either active or inactive by screen entry. Aircraft
Appendix C C-7 trajectories are constantly tested against the dimensions of active areas and alerts issued to the applicable sectors when violations are predicted.
C.1.35 Special Use Airspace (SUA). Air space of defined dimensions identified by an area on the surface of the Earth wherein activities must be confined because of their nature and/or wherein limitations may be imposed upon aircraft operations that are not a part of those activities. Some types of SUA are Alert Area, Controlled Firing Area, MOA, Prohibited Area, Restricted Area, and Warning Area.
C.1.36 Strategic. This term refers to the decision-making process by the pilot. Strategic decision-making addresses decisions related to flight planning, both preflight and in-flight.
C.1.37 Tactical. Thi s term refers to the decision-making process by the pilot. Tactical decision-making involves decisions of an operational nature that need to be applied immediately.
C.1.38 Text Product. An FIS product that is composed of text only.
C.1.39 Temporary Flight Restrictions (TFR). A TFR is a regulatory action issued by the FAA via the United States Notice to Air Missions (NOTAM) System (USNS), under the authority of Title 49 of the United States Code (49 U.S.C.). The FAA issues TFRs within the sovereign airspace of the United States and its territories to restrict certain aircraft from operating within a defined area on a temporary basis to protect persons or property in the air or on the ground. While not all-inclusive, TFRs may be issued for disaster or hazard situations such as: toxic gas leaks or spills, fumes from flammable agents, aircraft accident/incident sites, aviation or ground resources engaged in wildlife suppression, or aircraft relief activities following a disaster. TFRs may also be issued in support of VIP movements; for reasons of national security; or when determined necessary for the management of air traffic in the vicinity of aerial demonstrations or major sporting events.
C.1.40 Universal Access Transceiver (UAT). A U.S .-centric surveillance radio system providing other data link services that is intended to serve the majority of the General Aviation (GA) community. UAT transmits on 978 MHz and is approved per § 91.225 for use in all airspace below 18,000 feet mean sea level (MSL). UAT supports ADS-B, Automatic Dependent Surveillance–Rebroadcast (ADS-R), FIS-B, and Traffic Information Services–Broadcast (TIS-B).
C.1.41 Uplink. Communication link from the ground to the aircraft.
