Aviation Technology, Classifications, Regulations, and History

Comprehensive vocabulary flashcards covering aviation history, technology trends, FBO and operations types, FAA pilot and aircraft certification categories, and foundational aviation legislation.

Wright Flyer (1903)

A heavier-than-air aircraft constructed of ash wood, spruce, and cloth, powered by a $12\text{-horsepower}$ engine, that demonstrated powered, controlled flight at Kitty Hawk.

eVTOL

Electric Vertical Takeoff and Landing aircraft currently under development by aerospace companies with the goal of operating entirely on clean battery power.

Bessie Coleman

The first Black woman to earn a pilot’s license, who expanded representation in aviation and challenged discriminatory racial and gender barriers.

Tuskegee Airmen

A pioneering group of Black aviators who shattered expectations, challenged discriminatory barriers, and expanded representation in aviation.

Fixed Base Operator (FBO)

A commercial business granted the right by an airport authority to operate under an agreement or lease to serve general aviation aircraft with services such as fuel, parking, hangars, maintenance, and flight planning.

Commercial Aviation

Scheduled air operations carrying passengers or freight for hire (such as major airlines, regional carriers, FedEx, and UPS) as well as unscheduled air operations like on-demand jet charters and air taxis.

General Aviation (GA)

The portion of civil aviation that does not include scheduled or unscheduled air carriers, including flight training, corporate jets, emergency medical transport, crop dusting, and recreational flying.

Category (Airmen Certification)

A broad classification of aircraft printed on a pilot's license indicating operating privileges, such as Airplane, Rotorcraft, Glider, Lighter-Than-Air, Powered-Lift, Powered Parachute, or Weight-Shift-Control.

Class (Airmen Certification)

A classification of aircraft within a pilot certification category that shares similar operating characteristics, such as Single-Engine Land, Multi-Engine Land, Helicopter, or Gyroplane.

Airplane (Airmen Certification Category)

An engine-driven fixed-wing aircraft heavier than air that is supported in flight by the dynamic reaction of the air against its wings.

Rotorcraft (Airmen Certification Category)

A heavier-than-air aircraft that depends principally for its support in flight on the lift generated by one or more rotors, encompassing helicopters and gyroplanes.

Glider (Airmen Certification Category)

A heavier-than-air aircraft supported in flight by the dynamic reaction of the air against its lifting surfaces, whose free flight does not depend principally on an engine.

Lighter-Than-Air (Airmen Certification Category)

An aircraft capable of rising and remaining suspended by using a contained gas that weighs less than the air displaced by the gas, encompassing airships and free balloons.

Powered-Lift (Airmen Certification Category)

A heavier-than-air aircraft capable of vertical takeoff, vertical landing, and low-speed flight that relies principally on engine thrust or engine-driven lift for these regimes and on non-rotating airfoils for horizontal flight.

Powered Parachute (Airmen Certification Category)

A powered aircraft in which the lifting canopy is a flexible wing that is not in position for flight until the vehicle is in motion.

Weight-Shift-Control Aircraft (Airmen Certification Category)

A powered aircraft featuring a framed pivoting wing and a fuselage controllable in pitch and roll by altering the center of gravity relative to the wing.

Category (Aircraft Certification)

A grouping of aircraft based on intended use or operating limitations that dictates structural stress limits, passenger capacities, and airworthiness certification parameters.

Normal Category (Post-August 2017 Part 23)

A single performance-based category established under Amendment 23-64 for airplanes with a maximum passenger seating configuration of $19$ or fewer and a maximum takeoff weight of $19,000\,\text{pounds}$ or less.

Normal Category (Legacy)

A pre-August 2017 aircraft certification category intended for non-acrobatic operations, seating $9$ or fewer passengers (excluding pilots) with a maximum takeoff weight of $12,500\,\text{pounds}$ or less.

Utility Category (Legacy)

A pre-August 2017 certification category for aircraft carrying $9$ or fewer passengers with a MTOW of $12,500\,\text{pounds}$ or less, reinforced for limited acrobatics such as spins, lazy eights, and stalls.

Acrobatic Category (Legacy)

An aircraft certification category designed with an airframe structurally reinforced for extreme positive and negative G-forces, having no flight maneuver restrictions other than those proved necessary by flight testing.

Commuter Category (Legacy)

A legacy certification category for multi-engine airplanes intended for non-acrobatic passenger operations, limited to $19$ or fewer seats and a maximum takeoff weight of $19,000\,\text{pounds}$ or less.

Transport Category

An aircraft certification category governed by Part 25 for large, heavy aircraft exceeding $12,500\,\text{pounds}$, such as passenger jetliners and heavy cargo planes.

Primary Category

An aircraft certification category for aircraft produced under a basic design intended exclusively for personal, non-commercial pleasure flying.

Light-Sport Aircraft (LSA)

An aircraft certified under consensus industry standards that, under modern MOSAIC rules, is defined by safety performance metrics like maximum stall speed rather than a rigid gross weight limit.

Restricted Category

A certification category for special-purpose civil aircraft intended for specialized agricultural or industrial operations such as crop dusting, aerial surveying, firefighting, or glider towing.

Limited Category

An aircraft certification category consisting of military surplus aircraft modified for specific civilian operations.

Experimental Category

A special airworthiness category issued for amateur-built/kit planes, research and development, crew training, exhibition, air racing, and market surveys.

Provisional Category

A temporary aircraft certification category for newly designed or heavily modified aircraft undergoing rigorous flight testing prior to receiving a final type certificate.

Federal Aviation Administration (FAA)

An agency of the U.S. Department of Transportation responsible for promoting civil aviation safety through regulation enforcement, personnel and aircraft certification, safety oversight, and air traffic control management.

Air Commerce Act of 1926

A foundational federal legislative act that marked the birth of pilot and aircraft certification in the United States.

Civil Aeronautics Act of 1938

A legislative act that introduced federal economic regulations to civil aviation alongside existing safety oversight.

Federal Aviation Act of 1958

A statute that created the independent Federal Aviation Agency to centralize air traffic control and civil aviation safety, which was later renamed the Federal Aviation Administration upon joining the Department of Transportation in 1967.

Airline Deregulation Act of 1978

Legislation that phased out federal economic control over airline ticket pricing and route allocation, fostering the growth of budget airlines while preserving the FAA’s role in safety enforcement.

Airport and Airway Improvement Act of 1982 & AIR-21 (2000)

Federal legislative acts that funded aviation infrastructure improvements, modernized air traffic control systems, and expanded airport development grants.
