Airplane Stability

What is longitudinal stability in an airplane?

• The ability of the airplane to maintain a steady roll attitude

• The ability of the airplane to maintain a steady altitude

• The ability of the airplane to maintain a steady yaw attitude

• Longitudinal stability in an airplane refers to the aircraft's ability to maintain a steady pitch attitude without the need for constant control inputs.

What is a factor that affects longitudinal stability?

• The angle of incidence (angle of wing mounting)

• The pilot's experience

• The airplane's dihedral

• The distance between the center of gravity and the center of pressure

What is the purpose of a horizontal stabilizer in an airplane?

• To provide stability and control in pitch (up and down) movements.

• To provide stability and control in roll (side to side) movements

• To increase the speed of the airplane

• To adjust the altitude of the airplane

What is lateral stability in an airplane?

• Lateral stability in an airplane refers to its ability to maintain a straight and level flight path without rolling from side to side.

• Lateral stability means the airplane can only fly in a straight line

• Lateral stability is the airplane's ability to rotate around its vertical axis

• Lateral stability refers to the airplane's ability to fly upside down

What is the purpose of a vertical stabilizer in an airplane?

• To provide stability and control during flight by preventing yaw

• To reduce left-turning tendencies by decreasing slipstream effect

• To improve stability by preventing the need to constantly adjust pitch attitude

• To increase the speed of the airplane

What is directional stability in an airplane?

• The ability of an airplane to perform acrobatic maneuvers

• The ability to maintain a straight and steady course without excessive yawing or swerving.

• The ability of an airplane to change altitude quickly

• The ability of an airplane to take off and land smoothly

What is static stability in an airplane?

• Static stability in an airplane is its ability to fly at high speeds without stalling

• Static stability in an airplane is its tendency to return to its original position after being disturbed from its equilibrium state.

• Static stability in an airplane is its tendency to continue moving in the same direction after being disturbed

• Static stability in an airplane is its tendency to roll over and crash when disturbed

What is positive static stability?

• Positive static stability is when an object collapses after being disturbed.

• Positive static stability is when an object continues to move after being disturbed.

• Positive static stability is when an object returns to its original position after being disturbed.

• Positive static stability is when an object moves in the opposite direction after being disturbed.

What is negative static stability?

• Negative static stability is when an object becomes less stable as it is displaced from its original position.

• Negative static stability is when an object is perfectly stable regardless of its displacement from its original position.

• Negative static stability is when an object remains at the same level of stability as it is displaced from its original position.

• Negative static stability is when an object becomes more stable as it is displaced from its original position.

What is dynamic stability in an airplane?

• Dynamic stability in an airplane refers to its ability to maintain steady flight and recover from disturbances or changes in flight conditions.

• The amount of food and drinks available on the airplane

• The ability of an airplane to change colors during flight

• The speed at which an airplane can take off and land
