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.
