Aerospace vs. Aviation
What term describes flight operations that occur within Earth's atmosphere (airplanes, helicopters, balloons)?
Aviation
Name one engineering practice that involves making observations and collecting evidence during tests.
Plan and carry out investigations (or "analyze and interpret data" for observation-driven work)
What segment of aviation moves passengers and cargo for compensation on scheduled and non-scheduled flights?
Commercial aviation
Which military aircraft type is designed primarily to keep enemy aircraft out of the sky and engage in air-to-air combat?
Fighter
Which segment of aviation performs flight training, medical evacuation, aerial surveying, crop dusting, and private business flights?
General aviation
Which broader field includes both aircraft operations and spacecraft operations beyond Earth's atmosphere?
Aerospace
Which engineering practice asks you to create drawings, simulations, or small-scale models to explore ideas?
Develop and use models
Name one example of a cargo carrier and one example of a passenger air carrier mentioned in the lesson materials.
Cargo carrier example: UPS or FedEx; Passenger carrier example: American, United, or Southwest
Name a military aircraft role whose main purpose is to move supplies and troops.
Transport (or transport/tanker)
Which type of aviation serves scheduled passenger transport on published timetables (name the segment)?
Commercial aviation
True or False: "Aerospace" and "aviation" always mean exactly the same thing.
False
When engineers "engage in argument from evidence," what are they doing? (brief explanation)
They present claims supported by data and reasoning, critique and respond to others' claims, and use evidence to justify conclusions.
List two challenges commercial aviation faces that affect profitability or operations.
Examples of challenges: increasing air traffic, workforce shortages, infrastructure limits (aging airports/runways), environmental/noise concerns, competition from other transport modes, complex regulations.
Which type of military aircraft is equipped for high-resolution imaging and signal interception for national security?
Reconnaissance (specialized reconnaissance/intelligence aircraft)
List two missions carried out by general aviation that support public services (two distinct examples).
Examples: Air ambulance/medical evacuation and aerial surveying/mapping; also law enforcement patrols, agricultural application (crop dusting), package/document delivery, flight training.
Give one example of an activity that is aerospace but not aviation.
Ex: Launching/operating satellites or spacecraft beyond Earth's atmosphere (e.g., International Space Station operations, rocket launches).
Name two engineering practices from the list used in the Apollo 13 case study.
Examples: Define problems; Plan and carry out investigations; Develop and use models; Analyze and interpret data; Engage in argument from evidence (any two).
What are three needs modern commercial aviation helps meet (brief list)?
Needs met: moving people quickly over long distances; transporting cargo and time-sensitive goods; connecting remote regions and supporting global trade.
True or False: Drones (UAS) can be used for reconnaissance missions in military aviation.
True
According to FAA material, approximately what percent of the U.S. aircraft fleet is general aviation? (estimate from lesson texts)
About 60–65% (lesson text cites "more than 60 percent" and an estimate of 65%).
Explain in one sentence how aviation fits inside aerospace (use appropriate vocabulary).
Aviation is the subset of aerospace that focuses on aircraft operations within Earth's atmosphere, while aerospace includes both aeronautics (aviation) and astronautics (spaceflight).
Describe how one engineering practice (pick one) would help a team improve a balloon-powered "heavy lift rocket" design in the classroom activity.
Using "plan and carry out investigations": run repeated launches altering one variable (nozzle length or straw placement), record payload results, analyze patterns, and iterate design to increase payload capacity.
Explain one operational difference between long-distance jets, regional jets, and turboprops (focus on range or typical mission).
Operational difference example: Long-distance jets have much greater range and passenger capacity for transcontinental/international nonstop flights; regional jets serve shorter routes feeding hubs with fewer passengers; turboprops are most efficient at low altitudes and short ranges and operate from shorter runways.
Compare fighters and bombers in one sentence, focusing on their primary missions and one distinguishing feature.
Fighters primarily engage enemy aircraft and are highly maneuverable for air-to-air combat; bombers are designed to deliver large payloads to destroy ground targets and perform long-range strike missions.
Explain two advantages general aviation offers over scheduled airlines for businesses or emergency services.
Advantages: greater scheduling and routing flexibility (can fly to many small airports closer to final destinations) and faster, time-sensitive response for medical, business, or emergency missions.
