This paper describes display concepts and flight tests evaluations of flight management system
(FMS) flight plan integration into Honeywell's synthetic vision (SV) integrated primary flight
display systems (IPFD). The prototype IPFD displays consist of primary flight symbology overlay
with flight path information and flight director guidance cues on the SV external 3D background
scenes. The IPFD conformal perspective-view background displays include terrain and obstacle
scenes generated with Honeywell's enhanced ground proximity warning system (EGPWS)
databases, runway displays generated with commercial FMS databases, and 3D flight plan
information coming directly from on-board FMS systems. The flight plan display concepts include
3D waypoint representations with altitude constraints, terrain tracing curves and vectors based on
airframe performances, and required navigation performance (RNP) data. The considerations for
providing flight crews with intuitive views of complex approach procedures with minimal display
clutter are discussed. The flight test data on-board Honeywell Citation Sovereign aircraft and pilot
feedback are summarized with the emphasis on the test results involving approaches into terrainchallenged
air fields with complex FMS approach procedures.
This paper describes flight tests of Honeywell's synthetic vision primary flight display (SV PFD)
system prototype for helicopter applications. The primary differences between fixed-wing and
helicopter SV PFD and challenges of developing such an integrated system suitable for helicopter
applications are discussed. The visual environment and flight symbology specifically developed for
helicopter SV PFD are described. The flight test results and pilot evaluations of a prototype display
system on-board Honeywell's ASTAR helicopter are discussed.
This paper describes flight tests of a Honeywell Synthetic Vision (SV) Primary Flight Display prototype system integrated with Enhanced Ground Proximity Warning System (EGPWS). The terrain threat information from EGPWS system is displayed with synthetic vision terrain background in a coordinated 3D perspective-view and 2D lateral map format for improved situation awareness. The flight path based display symbology provides unambiguous information to flight crews for recovery and avoidance with respect to the threat areas. The flight tests further demonstrate that the SV based display is an effective situation awareness tool to prevent crew blunder in low visibility situations and further backup the accident chain that typically proceeds control flight into terrain (CFIT) accidents.
This paper describes flight tests of a Honeywell Synthetic Vision System (SVS) prototype operating in a hybrid-centered mode on a Primus EpicTM large format display. This novel hybrid mode effectively resolves some cognitive and perceptual human factors issues associated with traditional heading-up or track-up display modes. By integrating synthetic 3D perspective view with advanced Head-Up Display (HUD) symbology in this mode, the test results demonstrate that the hybrid display mode provides clear indications of current track and crab conditions, and is effective in overcoming flight guidance symbology collision and resultant ambiguity. The hybrid-centering SVS display concept is shown to be effective in all phases of flight and is particularly valuable during landing operations with a strong cross-wind. The recorded flight test data from Honeywell's prototype SVS concept at Reno, Nevada on board Honeywell Citation V aircraft will be discussed.
This paper describes flight trials of Honeywell Advanced 3D Primary Flight Display System. The system employs a large-format flat-panel avionics display presently used in Honeywell PRIMUS EPIC flight-deck products and is coupled to an on-board EGPWS system. The heads-down primary flight display consists of dynamic primary-flight attitude information, flight-path and approach symbology similar to Honeywell HUD2020 heads-up displays, and a synthetic 3D perspective-view terrain environment generated with Honeywell’s EGPWS terrain data. Numerous flights are conducted on-board Honeywell Citation V aircraft and significant amount of pilot feedback are collected with portion of the data summarized in this paper. The system development is aimed at leveraging several well-established avionics components (HUD, EGPWS, large-format displays) in order to produce an integrated system that significantly reduces pilot workload, increases overall situation awareness, and is more beneficial to flight operations than achievable with separated systems.
In this article, we describe a fiber-optic catheter-type pressure-sensing system that has been successfully introduced for medical diagnostic applications. We present overall sensors and optoelectronics designs, and highlight product development efforts that lead to a reliable and accurate disposable pressure-sensing system. In particular, the incorporation of an intelligent on-site self-calibration approach allows limited sensor reuses for reducing end-user costs and for system adaptation to wide sensor variabilities associated with low-cost manufacturing processes. We demonstrate that fiber-optic sensors can be cost-effectively produced to satisfy needs of certain medical market segments.
