23. Trim tabs are used to relieve control pressures on the surfaces to which they are attached. their movement is in the ____________ (same, opposite) direction with respect to the control surface.

Trim tabs are small surfaces attached to the main control surfaces of an aircraft, such as the ailerons or elevators. They are used to adjust the balance and reduce control pressures on these surfaces. When the control surface moves in one direction, the trim tab moves in the opposite direction, creating a counteracting force. This helps to relieve the control pressures and allows for smoother and more precise control of the aircraft.

26. The tail assembly is sometimes referred to as the ____________.

The tail assembly of an aircraft is commonly known as the empennage. The empennage consists of the vertical stabilizer (fin) and the horizontal stabilizer (elevator), which are located at the rear of the aircraft. It provides stability and control during flight by controlling the aircraft's pitch and yaw movements. The term "empennage" is derived from the French word "empenner," which means "to feather an arrow," highlighting its function in stabilizing the aircraft.

27. The wing components which extend from the leading edge to the trailing edge and form the shape of the wing camber is called ____________.

The wing components that extend from the leading edge to the trailing edge and form the shape of the wing camber are called ribs. Ribs are structural elements that provide support and stability to the wing, helping to maintain its shape and prevent deformation during flight. They are typically made of lightweight materials such as aluminum or composite materials and are spaced evenly along the wing's span. Ribs play a crucial role in distributing the aerodynamic forces evenly across the wing and are essential for the overall structural integrity of the aircraft wing.

28. Landing gears which incorporate a steerable nosewheel are referred to as a ____________ type gear.

A landing gear that includes a steerable nosewheel is commonly known as a conventional type gear. This type of landing gear is widely used in aircraft and allows for better maneuverability during taxiing and ground operations. The steerable nosewheel enables the aircraft to make tighter turns and navigate easily on the ground. The term "conventional" is used to distinguish this type of landing gear from other configurations, such as tricycle gear or tandem gear, which do not have a steerable nosewheel.

29. The wing component which extends from the root to the tip and absorbs the major portion of the wing camber are called ____________.

The wing component that extends from the root to the tip and absorbs the major portion of the wing camber is called a spar. The spar provides structural support and helps maintain the shape and strength of the wing. It is typically made of a strong and lightweight material, such as aluminum or carbon fiber, to withstand the forces and stresses experienced during flight. The spar plays a crucial role in distributing the aerodynamic forces evenly across the wing, ensuring stability and safety during flight.

30. Wings designed to carry the entire load without using external bracing, or struts, are termed "full ____________" wings.

Cantilever wings are designed to carry the entire load without the need for external bracing or struts. This means that the wings are self-supporting and do not require any additional support structures to bear the weight. Cantilever wings are commonly used in modern aircraft design as they provide a sleek and streamlined appearance, while also improving aerodynamic efficiency.

32. When the fuselage skin carries a major portion of the stresses, this type construction is called ____________.

In a semimonocoque construction, the fuselage skin carries a major portion of the stresses. This means that the skin of the fuselage is designed to bear a significant amount of the load and provide structural support, rather than relying solely on internal frameworks or bulkheads. This type of construction is commonly used in modern aircraft, as it allows for a lighter and more efficient design while still maintaining structural integrity.

33. Those which utilize a tailwheel are referred to as ____________ type gear.

The term "conventional" is used to describe the type of gear that utilizes a tailwheel. This means that the aircraft has two main wheels located towards the front of the aircraft and a smaller wheel, known as a tailwheel, located at the rear. This type of gear arrangement is commonly found in older aircraft designs and is known for its stability during takeoff and landing.
