This course covers advanced flight theory for turbine aeroplanes and the principles of cabin pressurization systems. It examines aircraft performance, stability, and control in various flight conditions, along with the effects of altitude, temperature, and pressure on aircraft operation. Students study the design and operation of pressurization and environmental control systems, including air conditioning, airflow management, and safety features. Emphasis is placed on system functionality, monitoring, and maintenance considerations, ensuring alignment with EASA Part- 66 Module 11 standards.
