4、Cockpit Display of Traffic Information (CDTI)PREFACEThis paper documents the activity of the SAE Subcommittee G-10 (*), Cockpit Display of Traffic Information (CDTI) Technology, to compile, categorize and track human factors issues related to the development of flight deck systems to display informa

5、tion about proximate other traffic. The display of such information is expected to provide operational benefits in the form of increased flight crew situation awareness, and to support revised ATC procedures leading to improved operational efficiency in the National Airspace System.The primary purpo

6、se of this document is provide a central source for the tracking of human factors issues concerning systems designed to display information about proximate traffic. It will also serve as guide to future research activities, as well as a resource for the development of concepts and procedures to maxi

7、mize the utility of CDTI systems. It is intended that this paper be a living document as well as a historical report on the relevant CDTI issues as they are developed and resolved. As such, this document will be updated regularly to reflect developments as they occur. Issues will not be removed as t

8、hey are resolved, but rather will remain to document the work that has been accomplished on this subject.SAE ARD50083 - 2 -1.

29、al Meteorological Conditions3.2 Definition of Terms:Absolute Altitude: Aircraft altitude referenced to mean sea level (QNH). Typically referred to as barometric corrected altitude.Accuracy: A measure of the difference between the reported A/V position as compared to the true position. Accuracy is us

30、ually defined in statistical terms of either: 1) a mean (bias) and a variation about the mean as defined by the standard deviation (sigma) or a root mean square (rms) value from the mean. The values given in this document are in terms of the two sigma variation from an assumed zero mean error.Airbor

31、ne Collision: This occurs when two aircraft that are in flight come into contact. The word “collision” is not an antonym of the word “separation”, as separation criteria are typically defined to create a significant zone around each aircraft which must not be entered for “separation” to be guarantee

32、d. As such, airborne collisions are subsets of airborne conflicts.Airborne Conflict: This occurs when two aircraft that are in flight come closer together than specified separation criteria. An airborne conflict does not necessarily result in a an airborne collision; however, it does represent a sit

33、uation considered hazardous, from which a collision may be possible without sufficient warning for a suitable pilot reaction.SAE ARD50083 - 6 -3.2 (Continued):Aircraft/Vehicle (A/V): Either (1) a machine or service capable of atmospheric flight, or (2) a vehicle on the airport surface movement area.

34、Airplane State: The variables required to fully describe the dynamic behavior of an airplane and to predict this behavior into the future. These variables include, speed, flight path vector, attitude (pitch and roll), and horizontal track. Aircraft state is often represented as a state vector, which

35、 comprises the minimum number of values required to fully specify the state; from the state vector, related values such as angle of attack, flight path angle and sideslip can be derived.Air Mass Data: Air mass data includes all aircraft sensor information which measures or is derived from the aircra

36、ft-local properties of the atmosphere. Direct measurements include air temperature, pressure, humidity and density; derived measurements include barometric corrected altitude (QNH), vertical speed and computed airspeed.Airspace: In the most general sense, airspace refers to the atmosphere in which a

37、ircraft operate, extending upwards from the surface of the earth. However, the term airspace also commonly denotes the spatial boundaries used to define areas restricted to civilian flight and to subdivide the airspace into areas controllable by individual air traffic controllers. These airspace bou

38、ndaries add a constraint to aircraft operations by limiting acceptable aircraft flight paths.Alert: A visual, auditory or tactile stimulus presented to attract the flight crews attention and convey some information concerning an event/situation.Aural Alert: Discrete tone/sound used for attention get

39、ting.Availability: Is the probability that a function is up and able to perform were it called on.Barometric Altitude: Geopotential altitude in the earths atmosphere above mean standard sea level pressure datum plane, measured by a pressure (barometric) altimeter.Barometric Altitude Error: For a giv

40、en true barometric pressure, P0, the error is the difference between the transmitted pressure altitude and the altitude determined using a standard temperature and pressure model with P0.Caution: Non-normal operational or aircraft system conditions that require immediate flight crew awareness and su

41、bsequent corrective or compensatory flight crew action.Closest Point of Approach (CPA): The minimum horizontal distance between two aircraft during a close proximity encounter, also know as miss distance.Clutter: Clutter refers to the negative impact of poorly organized and crowded displays. It gene

42、rally results in reduced display legibility, and/or in increases in the time needed to locate information on the display.SAE ARD50083 - 7 -3.2 (Continued):Cockpit Display of Traffic Information (CDTI): A Cockpit Display of Traffic Information (CDTI) is a generic display that provides the flight crew

43、 with surveillance information about other aircraft, including their position. Traffic information for a CDTI may be obtained from one or multiple sources (including ADS-B, TCAS, and TIS) and it may be used for a variety of purposes. Any means of communicating the information is acceptable (aural, g

44、raphical, head-up, etc.) as long as the information is conveyed effectively. Requirements for CDTI information will vary based on intended use of the data (i.e., application).Collision Avoidance: A maneuver taken to avoid a collision.Color Value: The attribute of a color that allows it to be classed

45、 on a scale from very dark to very light (Brightness is a perception that results from surface luminance and is a property of the object itself and of the light illuminating it.)Conflict: Any situation involving two or more aircraft, or an aircraft and an airspace, or an aircraft and ground terrain,

46、 in which the applicable separation minima may be violated.Conflict Avoidance: A maneuver taken to resolve a conflict.Conflict Detection: The process of projecting an aircrafts trajectory to determine whether it is probable that the applicable separation minimum will not be maintained between the ai

47、rcraft and another aircraft or vehicle. The level of uncertainty in the projection is reduced with increased knowledge about the situation, including aircraft capabilities, flight plan, short term intent information, etc.Conflict Management: Process of detecting and resolving conflicts.Conflict Prob

48、e: An airborne or ground based system that performs the process of conflict detection.Conflict Resolution: The process of identifying and or performing a maneuver or a set of maneuvers that are intended to resolve a conflict or potential conflict between the own ship and either (1) another aircraft

49、or vehicle, (2) a given airspace, or (3) terrain.Cooperative Surveillance: (1) Surveillance in which the target assists by cooperatively providing data using on-board equipment. (2) a concept which envisions a transfer of responsibility for aircraft separation from ground based systems to the air-crew of appropriately equipped aircraft, for a specific separation function such as In-trail merging or separation management of close proximity encounters. It is cooperative in the sense that ground-based ATC is involved in the handover process, and in the sense that a
