Future concept selection will be chosen to fulfill the requirements to be met…………  Range  Payload  Noise  Safety  Operating cost – (Profit for airlines !)  Manufacturing Cost (Profit for us !) That means understanding the options available to us, and the challenges ahead – does the latter infer that particular technologies have to be used, whether we like it or not ??  Reliable etc etc etc (OI, MMEL)  Cheap to maintain (DMC)

Product Safety Less than 15% of all accidents are caused by manufacturer related issues. 85% of all incidents due to operational factors, ie flight operations, weather, ATC. Closing the gap requires more focus on human factors Incident reporting key to improving safety environment
