<title>Flight tests of advanced 3D-PFD with commercial flat-panel avionics displays and EGPWS system</title>

Abstract

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 flightdeck 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 Honeywellís 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.

“…There have terrain boundaries in every layer, when aircraft fly over the boundary, the terrain data in RAM will be updated from ROM, as shown in fig.4. This hierarchical data is displayed in variable accuracy, and it can reduce the amount of data processed in memory, for largescale terrain display, it can reduce processing time [10]. As mentioned above, terrain data in ROM is also constructed by this hierarchical data structure.…”
