5、rations for Implementing Enhanced Synthetic Vision Systems in Vertical Flight Capable Platforms RATIONALEThe use of enhanced visual scene content as both a tool to increase situation awareness and as a sole flight guidance display has increased and will continue to increase. Correct implementation o
6、f these types of displays is essential and critical to safe vertical flight-specific operations.SAE G-10 Aerospace Behavioral Engineering Technology (ABET) Committee, specifically the G-10V Vertical Flight Subcommittee, has been tasked by Helicopter Association International (HAI) to provide documen
7、t guidance to implement Enhanced Synthetic Vision Systems (ESVS) into vertical flight aircraft (rotorcraft and powered lift air vehicles) used in operations where there is an increasing mishap record associated with loss of SA and inability to operate at low altitude in degraded visual environments
8、(DVE).FOREWORDSome of the intended uses of vertical flight and/or rotary-winged platforms (e.g., rotorcraft and powered lift vehicles), are inherently different than conventional fixed wing platforms. The issues associated with enhanced synthetic vision systems implemented into vertical flight platf
9、orms have some special considerations that must be addressed. These special considerations are related to these VF platforms ability to operate in off-airport and non-prepared facilities and unimproved landing areas. This document complements the SAE G-10 Enhanced Synthetic Vision Systems (ESVS) Sub
10、committee ARP5677 Human Engineering Considerations for Enhanced Synthetic Vision Systems by identifying and recommending human engineering best practices in the design of ESVS for, and implementation into, vertical flight platforms. It also draws from ARD50019, Human Engineering Issues for Enhanced
11、Vision Systems. This document is intended to provide a central source for recommending human engineering applications concerning ESVS in vertical flight platforms as an aid for development, design and implementation. Any comments or information concerning the data contained in the document shall be
12、directed to the subcommittee chairman. DEFINITIONAn enhanced synthetic vision system (ESVS) generates and displays visual imagery based upon sensor information of the out-of-cockpit scene in front of an aircraft, combined with a computer-generated visual scene representing the out-of-the-cockpit vie
13、w of terrain and selected scene data. The sensor(s) is/are designed to penetrate degraded visual environmental conditions better than unaided human vision, while the computer generated scene is unaffected by environmental conditions.SAE ARP6023 Page 2 of 25 TABLE OF CONTENTS 1.

20、oral technologies associated with design and/or implementation of Enhanced Synthetic Vision Systems (ESVS) in vertical flight aircraft. Any overlap into logic problems or hardware/software design shall be considered to be incidental to the human factors issues. Where the performance characteristics
21、of specific technologies are relevant they will be identified, and where performance criteria are relevant to specific intended functions/use they will be identified.From a regulatory view, intended function (Full Flight Guidance or Information/Situation Awareness support) has a tremendous effect up
22、on the design of an ESV System. However from a Human Engineering standpoint, the information on display must be discernible and comprehensible to the human operator in both cases and differences may be primarily in information content (required to support a specific task).The document is independent
23、 of candidate technologies and concentrates on human interface criteria. This document does not include consideration of detection and/or display of air targets or integration of systems such as TCAS. 1.1 Purpose This document addresses human factors considerations and requirements in data access, d
24、isplay comprehension, interpretation and application of imagery and integrated symbology in Enhanced (sensor) and Synthetic (database) Vision Systems as applicable to vertical flight platforms, and is a compilation of human factors recommended practices in the design and/or implementation of ESVS. I
25、t may be updated to reflect research and development results and as the technology improves and applications expand, the coverage of the document will be expanded.2.

40、erformance, excluding Flight Technical Error (FTE). Actual Navigation Performance is measured in terms of accuracy and integrity, and may be affected by the type and availability of navigation signals and equipment. NOTE: Also see Estimated Position Uncertainty (EPU).ALLOCENTRIC: Scene-based frame o
41、f reference particularly with respect to the objects spatial location; an observer-independent (possibly earth-fixed) frame of reference.CLUTTER: Clutter is an attribute of poorly organized and crowded displays. A cluttered display is one which uses an excessive number and/or variety of symbols, col
42、ors, or small spatial relationships. This causes increased processing time for display interpretation. It generally results in reduced display legibility, and/or in increases in the time needed to locateand interpret information on the display. COGNITIVE CAPTURE: Also known as cognitive tunneling, t
43、ask fascination or “attentional“ capture. The compelling phenomenon in which the observer is too focused on the instrumentation (display) and not on the whole environment.SAE ARP6023 Page 7 of 25 COMBINED VISION SYSTEM (CVS): The CVS concept involves a combination of synthetic and enhanced systems.
44、Some examples of a CVS include database-driven synthetic vision images combined with real-time sensor images superimposed and correlated on the same display.1COMMAND INFORMATION: Information that directs the pilot to follow a course of action in a specific situation (e.g., Flight Director or TCAS RA
45、 - resolution advisory). COMMAND REFERENCE FRAME: A symbol, appropriately colored, indicating the position within which the pilot shall place the flight path marker to affect the desired flight performance response. CONFORMAL INFORMATION: Information which correctly overlays the image of the real wo
46、rld, irrespective of the pilots viewing position. Conformal means having a 1:1 angular and scalar relationship. For displays the field of regard is the same as the field of view. COPLANAR DISPLAYS: Devices whose display surfaces lie in the same two dimensional plane. Also use this to describe views
47、like the plan view and VPD. DATA FUSION: Combining or consolidation and integration of separate data sources into a single entity where each data source is indistinguishable. DEGRADED VISUAL ENVIRONMENT: Atmospheric conditions where the visibility is restricted by obscurants or environmental conditi
48、ons optical perception of the pilot in the loop is diminished to less than VMC conditions as defined by FAR/CAR. DESIGN EYE POSITION: The midpoint of the line segment of the vision line connecting two points that represent the predicted eye positions of the extremes of the aircrew population. DESIGN
49、 EYE POSITION (DEP): The location, specified by the airframe manufacturer, from which the pilot can view cockpit instrumentation, have adequate external view, and can reach cockpit controls. (FAA AC-25.773-1) DESIGN VIEWING ENVELOPE(S): Range of possible angles, horizontal and vertical from the normal axis of the display, from which the unit would be viewed. There are two envelopes of concern: the primary envelope which defines the range of
