“A guide to aircraft fuel contents testing” is the title of a paper to be delivered by Tony Moore, technical director of Cirencester, UK-based BCF Designs, at 2 p.m. Wednesday in the Technology Theatre here at the airshow. Moore has led the BCF team working to improve fuel test safety for nearly two years. BAE Systems supported the work and has endorsed Moore’s paper, which explores potential safety hazards in and around aircraft and unveils BCF’s unique approach to the safe measurement of fuel systems embodied in aircraft design.
