Patricia Riddle* Boeing

We applied inductive classification techniques to data collected in a Boeing plant with the goal of uncovering possible flaws in the manufacturing process. This application led us to explore two aspects of classical decisiontree induction: ( 1) Preprocessing and postprocessing and (2) brute-force induction. For preprocessing and postprocessing, much of our effort was focused on the pre-processi...

Boeing 777 Flight Control System

INTRODUCTION Electronic controls systems have been used in commercial aviation for more than 40 years. With the introduction of the Concorde, the use of electronic systems (with mechanical backups) to manipulate the hydraulic controls used to fly by wire started the revolution on flight control. Digital systems were first used in the Airbus 310 where digital computers controlled flight control ...

The Extensive Use of Splines at Boeing

Splines are used extensively at Boeing and throughout much of the industrial world. There are very few remaining areas in either manufacturing or engineering in which these interesting functions have yet to play a role, and their use continues to grow at a rapid rate. A spline, for the purposes of this article, is defined as any function made up of one or more polynomial pieces joined together ...
