Flight Control Actuation System Considerations on Architecture Design and System Installation

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.

What Will You Learn

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
  • Describe various examples of Flight Control Actuation System architectures

Is This Course For You

This seminar is designed for engineers, executives, and other key personnel with little or no previous flight control knowledge or experience.
