What happens to an airplane with stability after a disturbance in straight-and-level flight?
It will eventually return to a state of equilibrium
Which term refers to the initial response that an airplane displays after its equilibrium is disrupted?
Static stability
If an airplane has positive static stability, what will it tend to do after the disruptive force is removed?
Return to its original position
What happens to the nose of an airplane with negative static stability if it pitches up due to wake turbulence?
It will continue to pitch up even after the turbulence goes away
How is the static stability of an airplane described if it tends to remain in a displaced position after the force is removed, but does not continue to move toward even greater displacement?
Neutral stability
What is the term used to describe an airplane that continues to move away from its original position after the disruptive force is removed?
Negative static stability
Which of the following is true about dynamic stability in an airplane?
Dynamic stability refers to the amount of time it takes for an airplane to react to static stability after being displaced from equilibrium.
What is the significance of oscillations in dynamic stability?
Oscillations indicate positive dynamic stability in an airplane.
What is the classification of an airplane with negative dynamic stability?
The airplane has oscillations that increase over time.
Which axis does an airplane rotate around when it pitches up or pitches down?
Longitudinal axis
What is the major factor in determining longitudinal stability for an airplane?
The weight and balance of the airplane
Where do all the lifting forces concentrate on an airplane's wing?
Center of lift
For good longitudinal stability, where is the center of gravity typically located in relation to the center of lift?
Forward of the center of lift
What happens if the center of gravity is too far forward in an airplane?
The forces at the tail may not be able to compensate
What is the purpose of the elevator trailing edge being deflected upward in an airplane's tail?
To create a downward force on the tail
What term is used to describe an airplane that continues to move away from its original position after a disruptive force is removed?
Dynamically unstable
What is the center of gravity also referred to as?
Center of balance
How many axes of rotation are there in an airplane?
3
What is the term used to describe an airplane that tends to remain in a displaced position after a disruptive force is removed, but does not continue to move toward even greater displacement?
Statically stable
Which axis does lateral stability of an airplane take place around?
Longitudinal axis
What is dihedral?
An upward wing angle with respect to the horizontal
What happens when one wing of an airplane with dihedral is lower than the other?
The airplane experiences a sideslip towards the low wing
What is the effect of sideslip on the low wing of an airplane with dihedral?
The low wing experiences an increase in lift
What happens to an airplane with negative static stability if it pitches up due to an external force?
It will continue to pitch up even after the external force is removed
What is the result of an airplane being longitudinally stable?
It will return to a properly trimmed angle of attack
Which axis does lateral stability of an airplane involve?
Roll axis
What is the purpose of dihedral in an airplane's design?
To enhance lateral stability
Which of the following is true about directional stability in an airplane?
It is created by the vertical fin
