Light-Sport Aerodynamics & Systems
Light-Sport Aerodynamics & Systems is a core knowledge area on the Sport Pilot FAA written exam. This hub collects our 16 in-depth, ACS-aligned light-sport aerodynamics & systems articles — each written in plain English and grounded in the official FAA handbooks. Work through them below, then drill the topic with practice questions.
Bernoulli's Principle vs. Newton's Third Law in Wing Lift
Lift is generated by two complementary forces acting on a wing: Bernoulli's Principle explains the pressure difference created by airflow, while Newton's Third Law accounts for the reactive force from deflecting air downward.
Angle of Attack and Lift Generation in Light-Sport Aircraft
Angle of attack (AOA) is the angle between the wing's chord line and the relative wind—understanding it is essential for predicting stall and maximizing lift in any light-sport aircraft.
Chord Line, Camber, and Airfoil Shape Effects on Performance
An airfoil's chord line, camber, and overall shape directly determine how much lift it generates and at what cost in drag — mastering these concepts is essential for understanding light-sport aircraft performance.
Four Forces of Flight: Lift, Weight, Thrust, and Drag in LSA
Every aircraft—including Light-Sport Aircraft—is governed by four forces: lift, weight, thrust, and drag. Understanding how they interact is essential for safe flight and passing your FAA knowledge test.
Stall Characteristics and Stall Speed in Light-Sport Aircraft
Stalls occur when the wing exceeds its critical angle of attack, not because of low speed alone. Understanding how stall speed changes with weight, bank angle, and power helps light-sport pilots stay safe and pass the FAA knowledge test.
Ground Effect and Its Impact on Light-Sport Aircraft Takeoff and Landing
Ground effect increases lift and reduces induced drag when an aircraft flies within one wingspan of the surface, affecting LSA takeoff climb and landing flare in ways every sport pilot must understand.
Stability and Control: Longitudinal, Lateral, and Directional Axes in LSA
Every light-sport aircraft rotates around three axes—pitch, roll, and yaw—and understanding how stability works along each axis is essential for safe, coordinated flight and for acing the FAA knowledge test.
Carbureted Engine Systems and Carburetor Ice Prevention in LSA
Carbureted engines power most Light-Sport Aircraft, making carburetor icing a critical hazard every LSA pilot must recognize and prevent. Learn how the system works, when ice forms, and how to eliminate it before it becomes an emergency.
Wing Loading and Its Effect on LSA Maneuverability and Stall
Wing loading—the ratio of an aircraft's weight to its wing area—directly shapes how a light-sport aircraft handles, stalls, and responds to gusts, making it a key concept for every sport pilot candidate.
Adverse Yaw and Rudder Coordination in Low-Speed Flight
Adverse yaw is a natural tendency for an aircraft to yaw opposite the intended turn during aileron input; proper rudder coordination—especially at low speeds—keeps the ball centered and prevents dangerous skids or spins.
Basic Electrical Systems in Light-Sport Aircraft
Light-sport and recreational aircraft use simple DC electrical systems to power avionics and lights; understanding the bus, battery, and alternator protects you and your equipment in flight.
Two-Stroke vs. Four-Stroke Engines Used in Light-Sport Aircraft
Light-sport aircraft use both two-stroke and four-stroke engines, each with distinct operating cycles, reliability profiles, and maintenance needs that every sport pilot candidate must understand.
Pitot-Static System and Airspeed Indicator Operation in LSA
The pitot-static system powers three critical flight instruments—airspeed indicator, altimeter, and VSI—and understanding how it works in an LSA helps pilots recognize failures before they become dangerous.
LSA Fuel Systems: Gravity-Fed vs. Fuel-Pumped Configurations
Light-sport aircraft fuel systems come in two basic configurations—gravity-fed and fuel-pumped—each with distinct operating procedures and failure modes every Sport Pilot candidate must understand.
Drag Types: Parasite Drag, Induced Drag, and the Lift-to-Drag Ratio in LSA
Parasite drag increases with speed while induced drag decreases—understanding both, and the lift-to-drag ratio, is essential for efficient, safe LSA flight and aces a common FAA knowledge-test topic.
Weight and Balance Calculations for Light-Sport Aircraft
Weight and balance calculations ensure a light-sport aircraft stays within its approved center-of-gravity envelope, directly affecting stability, control, and safety during every flight.
