In a pressurized aircraft fuselage, the structure must be designed to withstand which primary stress?
Answer: Tensile hoop stress
Internal pressurization creates tensile hoop stress that attempts to expand the fuselage diameter, requiring the skin to resist being pulled apart.
What is the purpose of a bleed air system on a turbine-powered aircraft?
Answer: To supply hot compressed air from the engine for cabin pressurization and anti-ice
Bleed air is extracted from engine compressor stages and used for cabin pressurization, air conditioning, anti-icing, and pneumatic systems.
Which rivet is most appropriate for use in areas that are accessible from one side only?
Answer: Cherry (blind) rivet
Blind rivets, such as Cherry rivets, are designed to be installed from one side when the back side is inaccessible.
A semi-monocoque fuselage structure derives most of its strength from:
Answer: A combination of skin, stringers, frames, and bulkheads working together
Semi-monocoque construction shares loads between the stressed skin and the internal framework of stringers, frames, and bulkheads.
What does a negative dihedral (anhedral) wing configuration primarily provide?
Answer: Decreased lateral stability for improved maneuverability
Anhedral reduces the natural lateral stability (dihedral effect), which is desirable in highly maneuverable or swept-wing high-speed aircraft.
When must a Required Inspection Item (RII) on an air carrier aircraft be re-inspected?
Answer: When the item was not inspected by an authorized inspector or was found defective and repaired
An RII must be reinspected if it was not properly inspected by an authorized RII inspector or if it was found defective and subsequently repaired.
What is the purpose of a bonding jumper on an aircraft fuel system component?
Answer: To provide an electrical ground path that prevents static charge buildup
Bonding jumpers provide a continuous electrical path to dissipate static electricity, preventing sparks that could ignite fuel vapors.
