 # Constraint Analysis {#mainpage}
-One of the essential aspects of aircraft design is to size the aircraft to meet the point performance requirement. This process involves the evaluation of the constraints within the Thrust to Weight and Wing Loading design space. As the tool is "sizing" the aircraft, it requires information about the aerodynamic performanca of the aircraft and the change of weight throughout the mission. Therefore this tool gets executed at the end of each loop to correctly size the aircraft.

 # Baseline Implementation
 The constraint analysis tool is established with an energy based approach which is coming from Jack D. Mattingly's Aircraft Engine Design book.
