The relationship between the length and width of a wing.

(a)  

A thin layer of air next to the surface of an airfoil which shows a

reduction in speed due to the air’s viscosity.

(a)  

The capability of an aircraft to respond to your flight inputs,

especially with regard to attitude and flight path.

(a)  

Acts in the opposite direction of flight, opposes the forward-

acting force of thrust, and limits the forward speed of the aircraft.

(a)  

Describes the form of motion an aircraft in static stability

undergoes when it tries to return to its original position.

(a)  

An aircraft that is designed to fly without an engine.

(a)  

The flat surfaces located behind the center of gravity tend to

weathervane with the wind.

(a)  

The rate at which temperature decreases with an increase in

altitude.

(a)  

The part of the airfoil that meets the airflow first.

(a)  

The force that created by the effect of airflow as it passes over

and under the wing.

(a)  

Characteristic of the aircraft that permits you to maneuver it

easily and allows it to withstand the stress resulting from the

maneuver.

(a)  

Caused by the separation of airflow from the wing’s upper

surface resulting in a rapid decrease in lift.

(a)  

A deviation from a trimmed state produces forces which

return the system to this trimmed state

(a)  

Aircraft speeds under Mach 1.

(a)  

Aircraft speeds between Mach 1 and 5.

(a)  

A reduction in the chord of a wing as measured from the root to

the tip of the wing.

(a)  

Forward-acting force which opposes drag and propels the

aircraft through the air.

(a)  

The last point on an airfoil that interacts with the airflow around

the wing.

(a)  

The product of density times velocity times length divided by

the viscosity coefficient. This is proportional to the ratio of

inertial forces and viscous forces (forces resistant to change

and heavy and gluey forces) in a fluid flow.

(a)  

A built in twist in the wing so that the trailing edge at the wingtip

is raised (Wash out) or lowered (Wash in). This significantly

affects the slow flight and stall characteristics of the wing.

(a)  

A force caused by the gravitational attraction of the Earth.
