+* 1. AIDA description
+************************************************************************
+The AIDA (Aircraft Inspection by Drone Assistant) system, is a Remotely Piloted Aircraft System (RPAS). 
+It is composed of a quadcopter drone, a control computer and a remote control. 
+The mission of this system is to help the pilot to inspect the aircraft before flight. 
+The quadcopter drone can be piloted in automated or manual mode. In manual mode, 
+the pilot guides the inspection of the aircraft by the drone. 
+In automated mode, the drone follows a flight plan and records the video of the inspected zone.
+
+************************************************************************
+* 2. Motivation and intended use
+************************************************************************
+AIDA provides a reference study case representative of the complexity and criticity found in aeronautical
+systems.
+Our intent is to provide a repository to gather all AIDA modellings in order to share different approaches and tools.
+
+If you plan to use AIDA as a study case it would be kind to inform the IRT Saint-Exupery contacts below. We would be pleased to answer your questions.
