Describe the function of the empennage.
Press to flip
The empennage, or tail section, provides stability and control in pitch and yaw directions.
Explain the function of the leading edge devices on aircraft wings.
Leading edge devices, such as slats and Kruger flaps, increase lift during takeoff and landing by altering the wing's leading edge.
What is the significance of the longitudinal axis in aircraft?
The longitudinal axis runs from the tail to the nose of the aircraft and is associated with roll movements.
Explain the role of yaw in aircraft movement.
Yaw refers to the rotation about the normal axis, causing the nose of the aircraft to move side to side.
What is the primary function of the fuselage in an aircraft?
The fuselage is the main body of the aircraft, housing the cockpit, passengers, and cargo.
What are the aerodynamic benefits of non-circular nacelle shapes?
Non-circular nacelle shapes help maintain ground clearance and can optimize aerodynamic efficiency.
How do flap-a-rons differ from standard flaps or ailerons?
Flap-a-rons combine the features of flaps and ailerons, offering both roll control and lift improvement.
What is the role of ailerons on an aircraft?
Ailerons are located on the outboard of the wings and control roll by moving in opposite directions (one up, one down).
How do flap track fairings contribute to an aircraft's performance?
Flap track fairings cover the flap mechanisms to reduce drag, improving the aircraft's aerodynamic efficiency.
Why might an aircraft use both inboard and outboard ailerons?
Large aircraft use both inboard and outboard ailerons to manage stress on the wings and control rolling speed more effectively.
What is the purpose of the lateral axis in an aircraft?
The lateral axis runs parallel to the wings and is associated with pitch movements.
Describe the movement associated with pitch in an aircraft.
Pitch refers to the rotation about the lateral axis, where the nose of the aircraft changes direction up or down.
What is the purpose of spoilers on an aircraft?
Spoilers are used to kill lift during landing, increase drag, and reduce landing distance.
What is the function of the normal axis in aircraft orientation?
The normal axis is vertical, running from top to bottom of the aircraft.
What are the characteristics of a simple hinged flap?
A simple hinged flap moves down across a hinge to increase the wing's camber and lift.
Differentiate between Fowler flaps and slotted flaps.
Fowler flaps move down and back to increase wing area and lift, while slotted flaps create air gaps between the moving parts to enhance lift.
