SAE ARP 4260 Photometric and Colorimetric Measurement Procedures for Airborne Electronic Flat Panel Displays [1] has recently been revised. This new revision reaffirms that ARP 4260 is pertinent to the aviation industry, changes the content to keep up with the state of the art, and adds clarification where needed. ARP 4260 contains methods used to measure the optical performance of airborne electronic flat panel display systems and is referenced in SAE ARP 4256, Design Objectives for Liquid Crystal Displays for Part 25 (Transport) Aircraft [2] and in SAE AS 8034, Minimum Performance Standard for Airborne Multipurpose Electronic Displays [3].

This paper describes a project that is currently being undertaken in the United Kingdom. The project is to investigate the structural response of a passenger vehicle under five conditions of frontal impact: i) Full frontal impact (0 degree) into a rigid barrier ii Angled impact (30 degree) into a rigid barrier iii) 40% overlap impact into a rigid barrier iv) Full frontal impact (0 degree) into a deformable barrier v) 40 % overlap impact into a deformable barrier. The work has two primary aims. Firstly to provide structural engineers with information on the degree of complexity that is required to accurately model the crashworthiness of the vehicle. Secondly to provide information that can be used by legislators when setting future vehicle safety regulations. The paper concentrates on the crash analysis simulations that are being performed in the non-linear finite element code OASYS DYNA3D.
