This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne electronic flat panel display (FPD) systems. The methods described are specific to the direct view, liquid crystal matrix (x-y addressable) display technology used on aircraft flight decks. The focus of this document is on active matrix, liquid crystal displays (LCD). The majority of the procedures can be applied to other display technologies, however, it is cautioned that some techniques need to be tailored to different display technologies. The document covers monochrome and color LCD operation in the transmissive mode within the visual spectrum (the wavelength range of 380 to 780 nm). These procedures are adaptable to reflective and transflective displays paying special attention to the source illumination geometry. Photometric and colorimetric measurement procedures for airborne direct view CRT (cathode ray tube) displays are found in ARP1782. Optical measurement
This document recommends design and performance criteria for aircraft lighting systems used to illuminate flight deck controls, luminous visual displays used for transfer of information, and flight deck background and instrument surfaces that form the flight deck visual environment. This document is for aircraft, except for applications requiring night vision compatibility.

At CES 2022 Panasonic Automotive Systems Company of America unveiled AR HUD 2.0 (Augmented Reality Head-Up Display 2.0), the first system to include a new, patented eye-tracking system (ETS). If you've ever thought about what exists beyond the limits of a HUD and the small rectangular box it displays on the windshield, welcome to the world of AR. And note that AR is not VR, Virtual Reality; VR is a space in which headsets or special glasses allow the wearer to experience a 3D world that doesn't exist except in this technology. It's increasingly used in automotive interior design.
Researchers have developed a LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by “seeing through” objects to alert of potential hazards without distracting the driver.
Integration of a driver monitor system (DMS) in a head-up display (HUD) gives the monitor camera a continuous view of the driver’s face, since the driver always faces the road ahead. However, with both infrared (IR) illuminator and IR camera packaged in the HUD, reflectivity of the windshield is important at IR wavelengths used by the camera. Not only is windshield IR reflectivity important for a clear camera image of the driver’s face, but increasing windshield reflectivity also decreases the effect of ambient sunlight on the camera image of the driver’s face. We describe a method to measure windshield reflectivity, both for the 940 nm band used by a DMS, and for visible light for the HUD. The measurement method uses a fiber-optic spectrometer, two collimating lenses, and a method to compensate for sample tilt. The lenses are mounted on a stage that adjusts the height above the sample. As an example, this method was used to characterize an IR reflecting windshield, prepared for a
This report identifies the reasons for, and results associated with, the conduct of a flight simulation research project evaluating the effect of low powered laser beam illumination of pilot crewmembers operating in the navigable airspace. This evaluation was primarily concerned with the possible degradation of pilot performance when illuminated by a laser while operating in an airport terminal area where pilot workloads are normally at their maximum.
This document recommends criteria and requirements for a flight management system (FMS) for transport aircraft. The FMS shall provide the functions of lateral navigation, vertical navigation, and performance management and may include time of arrival control. The FMS design shall take human factors considerations into account to produce a fault tolerant system.
This SAE Aerospace Recommended Practice (ARP) sets forth design and operational recommendations concerning the human factors/crew interface considerations and criteria for vertical situation awareness displays. This is the first of two recommended practice documents that will address vertical situation awareness displays (VSAD). This document will focus on the performance/planning types of display (e.g., the map display) and will be limited to providing recommendations concerning human factored crew interfaces and will not address architecture issues. This document focuses on two types of VSAD displays: a coplanar implementation of a profile display (side projection) and a conventional horizontal map display; and a 3D map display (geometric projection). It is intended for head down display applications. However, other formats or presentation methods, such as HUDs, HMDs and 3D audio presentations may become more feasible in the future. Even though the relationship of the vertical
The recommendations of this document apply to such aircraft as are able to perform both normal angle and steep IMC approaches, the latter being defined as those approaches having a final approach segment angle greater than 4°. Such aircraft can include both conventional and STOL fixed-wing aircraft, commercial air transport and/or utility and normal category helicopters, compound helicopters and powered lift vehicles (tiltrotors, tiltfans, tiltwings, etc.).
The function of a multifunctional display (MFD) system is to provide the crew access to a variety of data, or combinations of data, used to fly the aircraft, to navigate, to communicate, and to manage aircraft systems. MFDs may also display primary flight information (PFI) as needed to insure continuity of operations. This document sets forth design and operational recommendations concerning the human factors considerations for MFD systems. The MFD system may contain one or more electronic display devices capable of presenting data in several possible formats. MFDs are designed to depict PFI, navigation, communication, aircraft state, aircraft system management, weather, traffic, and/or other information used by the flight crew for command and control of the aircraft. The information displayed may be combined to make an integrated display or one set of data may simply replace another. The information contained in this document can be applied to the design of all MFDs, including
This document sets forth general, functional, procedural, and design criteria and recommendations concerning human engineering of data link systems. The recommendations are based on limited evidence from empirical and analytic studies of simulated data link communication, and on experience from operational tests and actual use of data link. However, because data are not yet available to support recommendations on all potentially critical human engineering issues these recommendations necessarily go beyond the data link research and include requirements based on related research and human factors engineering practice. It is also recognized that evolution of these recommendations will be appropriate as experience with data link accumulates and new applications are implemented. This document focuses primarily on recommendations for data link communications between an air traffic specialist and a pilot, i.e., air traffic services communications, although some recommendations address use of
This Aerospace Standard (AS), establishes minimum performance standards for those sensors, computers, transponders, and airplane flight deck controls/displays which together comprise a Takeoff Performance Monitor (TOPM) System. This standard also defines functional capabilities, design requirements, and test procedures. A TOPM system is intended to monitor the progress of the takeoff and to provide advisory information which the crew may use in conjunction with other available cues to decide to continue or abort the takeoff. See Appendix A for supplementary information relating to NTSB, CAA, and ad hoc committee concerns and background information.
The head-up display system can overlay the real object with the projected image to assist the driver in driving. However, when road conditions are bad, the continuous vibration of the vehicle will cause the vehicle to tilt and shift. At this time, the projected image and the real object do not overlap well. This paper presents a correction algorithm for a head-up display system. The algorithm corrects the position of the projected image by inputting the tilt state of the vehicle. In this paper, the coordinate axis with the driver's eye as the origin is first established. Then the tilt state of the vehicle is decomposed into the rotation angle in three directions and the displacement in the vertical direction. Finally, the position of the projected image is corrected by inputting the tilt state of the vehicle so that the projected image can remain on the real object at all times. The simulation model is established in Unity3D. The effectiveness of the correction algorithm is verified by
This document presents criteria for flight deck controls and displays for Airborne Collision Avoidance Systems.
This SAE Recommended Practice defines the various types of information required by the collision repair industry to properly restore light-duty, highway vehicles to their pre-accident condition. Procedures and specifications are defined for damage-related repairs to body, mechanical, electrical, steering, suspension, and safety systems. The distribution method and publication timeliness are also considered.
This document recommends design and performance criteria for aircraft lighting systems used to illuminate flight deck controls, luminous visual displays used for transfer of information, and flight deck background and instrument surfaces that form the flight deck visual environment. This document is for commercial transport aircraft except for applications requiring night vision compatibility.
This SAE Aerospace Standard (AS) specifies minimum performance standards for all types of electronic displays and electronic display systems that are intended for use in the flight deck by the flight crew in all 14 CFR Part 23, 25, 27, and 29 aircraft. The requirements and recommendations in this document are intended to apply to all installed electronic displays and electronic display systems including those that have a touch screen interface within the flight deck, regardless of intended function, criticality, or location within the flight deck, but may also be used for non-installed electronic displays. This document provides baseline requirements and recommendations (see 2.3 for definitions of “shall” and “should”). This document primarily addresses hardware requirements, such as electrical, mechanical, optical, and environmental. It does not address system specific functions. It does not contain an exhaustive or comprehensive list of requirements for specific systems or functions
The adoption of head-up displays (HUDs) is increasing in modern automobiles. Yet integrating this technology into vehicles with standard windshield (WS) laminates can create negative effects for drivers, primarily due to the thickness of glass used. The double ghosting in HUD images is typically overcome by employing a wedged PVB between the two glass plies of the laminate. Another solution is to reduce the thickness of the glass without impacting the overall windshield toughness. Although this still requires the use of a wedged PVB to eliminate HUD ghosting, the thinner glass provides opportunity to increase the image size. However, reducing the thickness of a soda-lime glass (SLG) ply or plies in a conventional soda-lime glass (SLG) laminate can significantly impact the robustness of the laminate to external impact events. This paper will review how a hybrid laminate made from one ply of a relatively thick SLG and a second ply of relatively thin, chemically-strengthened glass, will
Head-up displays (HUDs) give visual information to drivers in an easy to understand manner and prevent traffic accidents. Augmented reality head-up displays (AR-HUDs) display the driving information overlaid on the actual scenery. The AR-HUD must allow the visual information and the actual scene to be viewed at the same time, and a sense of depth and distance are key factors in achieving this. Binocular parallax used in stereoscopic 3D display is one of the most useful methods of providing a sense of depth and distance. Generally, stereoscopic 3D displays must limit the image range to within Panum’s fusional area to ensure fusion of the stereoscopic images. However, when using a stereoscopic 3D display for an AR-HUD, the image range must extend beyond Panum’s fusional area to allow the visual information and the actual scene to be displayed at the same time. In this study, we investigate the visibility of images displayed beyond Panum’s fusional area on a stereoscopic 3D display for an
It's become a rarity for automakers to place manual-transmission models in their press-evaluation fleets, but the Elantra Sport's direct (if light) lever action and skillfully-weighted clutch pedal made it all the more pleasing to manual-shift for a week. Although the Sport has a unique, assertively-styled grille and other panels that differentiate it from the rest of the Elantra lineup, it's not just an appearance job-there's something going here: don't forget, Hyundai hired BMW's former M-division engineering boss a couple years ago. There's a useful 201 hp from the turbocharged, direct-injected 1.6-L 4-cylinder and scant lag. With the 6-speed manual, the Sport's just on the civil side of fast-and is a treat to hustle around in the middle gears.
Continental is developing its innovative 3D instrument display cluster with the aim of bringing it to production within the next 24-36 months. The display, previewed by Automotive Engineering at a recent technology meeting, features a high-definition (1920 × 720 pixel) 12.3-in screen but is suitable for displays measuring 15 in. “The proliferation of displays in the interior of the cabin allows for more individuality, variety of shapes and appearances” a Continental engineer explained, adding, “Instead of relying on flat, one-dimensional surfaces, we are offering a solution that allows designers to play with the interior in a creative and cost-efficient way.”
A new concept of Head Up Display is presented, using the windshield as a transparent screen. This breakthrough technology does not need the use of complex combiner, bulky optics and overhead projection unit. The novel system uses several holographic optical elements to perform a 3D stereoscopic display, with the ability to present floating graphical objects in a large field of view. Augmented Reality display will be possible, increasing considerably the User Experience and situational awareness, without the need of wearing a bulky and complex Head Mounted Display.
