An application of statistical techniques to estimate engineering man-hours on major aircraft programs

Data on 23 lots of various aircraft programs were gathered. Total engineering man-hours, and information on performance, weight, area, avionics systems, data, and schedule were subjected to least squares analysis. An equation is presented which indicates a relationship between total engineering manhours and a set of seven predictor variables. While the equation derived could only be used with confidence by the manufacturer whose data was analyzed, this article should be looked upon as demonstrating a method of data analysis which others may also find useful, not only for predicting engineering manhours in major aircraft programs, but also in other situations where there is an abundance of possible predictor variables, and the problem is to sort out a meaningful subset of these variables. In order to demonstrate the viability of the formula obtained, comparisons were made with various bid programs.     

Risk Analysis

Abstract

The changes that have taken place in world politics over the last five years have led to a reassessment of the type, size and shape of potential conflicts. As witnessed during the Gulf War, such changes pose new challenges to allied forces and emphasise in particular the crucial role of air supertortty. Pbil Tittler argues the need for fully integrated air power defence systems to provide upto-date technology, flexibility and mission eflectiveness, plus affordability, to ensure sucess in any future operations.     

Past failures and future problems: the psychology of irregular war

Personal cognitive processes inform how individuals understand their environment. Cultural variation, fundamental attribution error, causal attribution, and durability bias create obstacles to Western understanding of irregular war and have created a significant institutional bias in how the US military perceives its enemies- a perception only somewhat softened after a decade of irregular war. United Special Operations Command (USSOCOM) is in a better position to overcome these problems through persistent engagement. In the event of major conflict, environmentally sensitized military planners will be better able to achieve military and policy objectives.     

Peacetime military innovation through inter-service cooperation: The unique case of the U.S. Air Force and Battlefield Air Interdiction

ABSTRACT

Military doctrine assures a nation’s survival. Yet even when faced with a security threat that requires change, militaries rarely innovate but instead adhere to old doctrines that enhance autonomy, reduce uncertainty and claim resources. Existing theories cannot explain an important case of peacetime military innovation when the U.S. Air Force adopted Battlefield Air Interdiction to support the Army’s AirLand Battle doctrine. A revised theory of peacetime military innovation through inter-service cooperation resulting from external and internal threats explains not only why innovation occurred with Battlefield Air Interdiction but also why such successful cases are so rare.
