Hotel & Travel Information

The purpose of this four hour short course is to provide information to understand how is established the basic architecture of a Flight Control Actuation System of a transport airplane, i.e. understanding the rationale for the distribution of the control surfaces, power sources, actuators and computers.

Learning Objectives
By attending this seminar, you will be able to:

  • Understand the Flight Control Actuation System main requirements
  • Identify technical alternatives covering various aspects of Flight Control Actuation System architecture
  • Identify the impact of some installation constraints on Control Actuation System architecture

    Instructor(s): Dominique van den Bossche
    Dominique van den Bossche is presently an independent consultant for European and US flight control actuation companies. He retired from Airbus in 2009 as the Head of Department in charge of the Primary Flight Control Actuation and Hydraulics Department in the Systems and Integration Tests Center of Competence of the Airbus Engineering organization. He was responsible for the management of R&T, design, development, validation and in-service engineering support of the Primary Flight Control Actuation, Hydraulic Generation and Hydraulic Distribution equipment, for all Airbus models from A300B to A380, A400M and A350. Previously at Aerospatiale, Mr. van den Bossche was a development engineer in charge of A300B hydromechanical flight control equipment. He was also involved in the A310, A300-600, ATR42/72 and A320 flight control equipment developments. He was appointed as the Head of the Pilot Controls and Primary Flight Control Actuation Group prior to his appointment to Head of Department. Holding four patents involving flight control actuation equipment design and application, Mr. van den Bossche has also been recognized with an award by the French Academy of Technology for his achievements on electrohydrostatic actuation technology. In addition to actively serving on the SAE-A6 Fluid Power, Actuation & Control Technology as Vice-Chairman, his industry service also includes serving on the ISO TC20/ SC10/WG9 Hydraulics & Flight Control Actuation committee and the Mechanical Branch Committee and Hydraulic & Actuation working group of the French “Bureau de Normalisation Aéronautique”. He currently teaches Flight Control Actuation Systems at the Institut Universitaire de Technologie (IUT) in Blagnac, France and on-demand courses for various companies and organizations. Mr. van den Bossche received a Master’s Degree in Aeronautics at the French “Ecole Nationale Supérieure d’ Ingénieurs de Constructions Aéronautiques”.
