Across
- 3. The reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system.
- 5. The main body of an aircraft.
- 7. Something that moves something above another or moves something to a higher position.
- 9. A structure with curved surfaces designed to give the most favourable ratio of lift to drag in flight, used as the basic form of the wings, fins, and horizontal stabilizer of most aircraft; an aerofoil.
- 11. To operate or fly (an aircraft) without propulsion from wings or an engine.
- 12. Pull (someone or something) along forcefully, roughly, or with difficulty.
- 13. The science or art involved with the study, design, and manufacturing of air flight–capable machines, and the techniques of operating aircraft and rockets within the atmosphere.
- 16. A pilot.
- 18. The act of operating or flying (an aircraft) without propulsion from wings or an engine.
- 20. A vector sum of True Airspeed (TAS) and wind velocity.
- 22. Raise to a higher position or level.
Down
- 1. One of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear.
- 2. An altimeter is a device that measures altitude, the distance of a point above sea level. Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above Earth's surface.
- 4. The principle that states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.
- 6. The activities surrounding mechanical flight and the aircraft industry.
- 8. A primary flight control surface which controls rotation about the vertical axis of an aircraft. This movement is referred to as "yaw". The rudder is a movable surface that is mounted on the trailing edge of the vertical stabilizer or fin.
- 10. A measure of the force that can cause an object to rotate about an axis.
- 14. Move in a particular direction by turning over and over on an axis.
- 15. Three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it.
- 17. A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight.
- 19. Knots is how the speed of aircraft and boats is measured.
- 21. The pitching moment on an airfoil is the moment (or torque) produced by the aerodynamic force on the airfoil if that aerodynamic force is considered to be applied, not at the center of pressure, but at the aerodynamic center of the airfoil.
