The student has the ability to approach an aerodynamics design of an airplane. He is able to identify the better apprach to the aerodynamics evaluation for a given problem, taking into account the caabilities of different approach (numerical os experimental), the cost and the time necessary to have the result. The student is also able to consider the aerodynamcs aspects of the design on respect to the complete design.
During the oral exam the student must be able to demonstrate his/her knowledge of the course material and be able to discuss the reading matter thoughtfully and with propriety of expression.
