During a routine maintenance check of a commercial airliner, a technician focuses on inspecting the turbine exhaust system. What are the major components they should examine?

• Exhaust sleeve and plug

• Fan cowl and thrust reverser

• Inlet cowl and core cowl

• Low pressure compressor and high pressure compressor

During a commercial flight, what is the role of the inlet cowl located at the front of the jet engine?

• Controls airflow around and through the engine

• Provides access to various areas of the engine case and fan case

• Minimizes aerodynamic drag of the engine installation

• Protects components within from hostile flight environments
