Course: Aviation Security (Lecture)

Lecturer:

Ralf God

Language:

German

Period:

Winter Semester

Content:

The objective of the lecture with the corresponding exercise is the acquisition of knowledge about tasks and measures for protection against attacks on the security of the commercial air transport system. Tasks and measures will be elicited in the context of the three system components man, technology and organization.

The course teaches the basics of aviation security. Aviation security is a necessary prerequisite for an economically successful air transport system. Risk management for the entire system can only be successful in an integrated approach, considering man, technology and organization:
• Historical development 
• The special role of air transport 
• Motive and attack vectors 
• The human factor 
• Threats and risk 
• Regulations and law 
• Organization and implementation of aviation security tasks 
• Passenger and baggage checks 
• Cargo screening and secure supply chain 
• Safety technologies
