Laws
What is Newton's Third Law?
For every action, there is an equal and opposite reaction.
What are the two types of drag?
Induced and Parasite
Exceeding the Critical Angle of Attack
What are the four forces of flight?
Lift, Weight, Thrust, and Drag
What part of the plane is an airfoil?
Wings
What is Newton's First Law?
An object at rest or in motion remains at rest or continues moving unless acted on by an outside force.
Induced drag is caused by what?
Wingtip vortices
What are the three axes of flight?
Lateral Axis, Longitudinal Axis, and the Vertical Axis
What is the point on the aircraft at which weight is concentrated/felt?
Center of Gravity (CG)
As load factor increases, how does it affect stall speed?
Stall speed increases
Who created the venturi?
Bernoulli
What are the three types of Parasite Drag?
Form Drag, Skin Friction Drag, and Interference Drag
What part of the aircraft provides directional stability?
Vertical tail fin
Thrust generally acts parallel to what axis?
Longitudinal Axis
Angle of Attack is defined as what?
The angle between a wing's chord line and the relative wind.
Bernoulli's Principle states what?
As the velocity of a moving fluid increases, the pressure within the fluid decreases
To avoid wake turbulence on landing, what must we do?
Stay above the plane's glide path and land beyond their touchdown point
List TWO characteristics of an aft CG
Less stable, unfavorable stall recovery, higher cruise speed, lower stall speed
What is the point on the aircraft at which lift is concentrated/felt
Center of Lift (CL)
Define Mean Camber Line?
The centerline between the curvature of the upper surface and the lower surface.
Explain Gyroscopic Precession
Applying a force to a spinning gyroscope causes the force to be felt 90 degrees later in the direction of rotation
At what height above a surface does an aircraft experience ground effect?
Within one wingspan of the surface
What is dihedral?
The upward angle of the wing tips compared to the wing root
What are the stages of a spin?
Entry, Incipient, Developed, and Recovery
What was Bernoulli's first name?
Daniel
