Principles of Flight Vocabulary Quiz

What is the definition of Adverse Yaw?

• The motion of an aircraft about the longitudinal axis, resulting in one wing moving upwards and the other downwards.

• The drag caused by the lowered aileron during a turn, causing the nose of the airplane to point away, or outwards, from the direction of the turn.

• The force generated primarily by the motion of air passing over an aircraft's wings.

• A system whereby the forces acting upon an aircraft are measured from the center of gravity, used when defining the pitch, roll and yaw axes.

What does the term Aileron refer to?

• The body of an aircraft.

• The imaginary line, from wingtip to wingtip, about which an airplane pitches.

• The part of the airplane, located at the rear of the wing, that increases lift on one wing while reducing the lift on the other in order to roll the aircraft sideways and allow it to turn.

• The effective point whereby all weight is considered to be; the same point where the axes of flight meet.

What is the Axis in the context of aviation?

• The part of the airplane that increases lift on one wing while reducing it on the other to roll the aircraft.

• The body of an aircraft.

• An imaginary line around which an airplane can turn.

• The motion of an aircraft about the lateral axis, resulting in the nose and tail moving upwards and downwards.

What is the purpose of the Body-Axis System?

• To provide the effective point where all weight is considered to be.

• To resist the force of air against an aircraft's forward motion.

• To define the pitch, roll, and yaw axes based on the forces acting upon an aircraft from the center of gravity.

• To move parts of an aircraft to direct airflow, enabling the aircraft to roll, pitch, and yaw.

What is the Center of Gravity (CG) in aviation?

• The part of an aircraft that can be moved to direct airflow.

• The effective point whereby all weight is considered to be; the same point where the axes of flight meet.

• The imaginary line, from wingtip to wingtip, about which an airplane pitches.

• The body of an aircraft.

What is the function of a Control Surface?

• To provide lift by generating force from the motion of air over the wings.

• To measure the forces acting upon an aircraft from the center of gravity.

• To move in order to direct airflow, enabling the aircraft to roll, pitch, and yaw.

• To define the range in which the aircraft's center of gravity must be located to fly.

What is Coordinated Flight?

• The motion of an aircraft about the lateral axis.

• The body of an aircraft.

• Flight during which the plane’s ailerons and rudder work together to keep the nose and tail traveling in the same direction.

• The resistance of air against an aircraft's forward motion.

What does Drag refer to in aviation?

• The motion of an aircraft about the lateral axis.

• The resistance of air against an aircraft's forward motion.

• The imaginary line around which an airplane can turn.

• The effective point where all weight is considered to be.

What is the purpose of the Elevator on an aircraft?

• To move the aircraft about the longitudinal axis.

• To stabilize the plane and enable pitch adjustments.

• To generate lift by the motion of air over the wings.

• To define the range in which the aircraft's center of gravity must be located to fly.

What is the Fuselage?

• The imaginary line, from wingtip to wingtip, about which an airplane pitches.

• The body of an aircraft.

• The part of the airplane that increases lift on one wing while reducing it on the other to roll the aircraft.

• The effective point where all weight is considered to be.
