The course aims to provide the basic knowledge of the flight mechanics of fixed and rotary wing aircraft. Starting from the illustration of the architecture of the different types of aircraft, and hence of the role of their components, the objective of the course is to provide the student with knowledge relating to the following topics: 1) aircraft performance and identification of the main parameters of influence; 2) pilot commands and behavior of aircraft in the main operational situations; 3) trimmed flight conditions and aircraft static stability; 4) main airworthiness regulations underlying the aircraft design specifications. At the end of the course the student will be able to: 1) communicate with clarity, competence and language properties the issues related to the study of the flight mechanics of fixed and rotary wing aircraft; 2) examine aircraft flight during a typical mission; 3) contribute to the definition of the conceptual design of an aircraft.

optionalType of evaluation
The students are assessed through an initial written exam with open-ended questions, which determines (based on the score) whether they can proceed to the oral exam. During the oral exam, the written test is discussed with the possibility of further exploring some topics, as well as the project the students have completed for an assignment proposed by the instructor during the course.
