How Much Are You Familiar With Aircrafts?

Explanation
The Wright Brothers are credited with making the first aircraft. They were two brothers, Orville and Wilbur Wright, who successfully designed, built, and flew the world's first powered airplane in 1903. Their innovation and contributions to aviation revolutionized the way we travel and paved the way for modern aircraft.

Explanation
Aeronautics refers to the process of building and designing an aircraft. It involves various aspects such as aerodynamics, materials science, propulsion systems, and structural design. Aeronautical engineers use their knowledge and expertise to create safe and efficient aircraft that can withstand the forces of flight. This field encompasses both the theoretical and practical aspects of aircraft design, ensuring that the final product meets all necessary standards and regulations.

Explanation
UAVs, or Unmanned Aerial Vehicles, are aircraft that are flown by computers. These aircraft do not require a human pilot on board and are controlled remotely or autonomously. The use of computers allows for precise control and navigation, making UAVs an efficient and effective tool in various industries such as military, surveillance, and aerial photography.

Explanation
The Airbus A380 is the correct answer because it is currently the world's largest passenger airliner. It has a maximum seating capacity of up to 853 passengers and is known for its spaciousness and comfort. The A380 is manufactured by Airbus, a leading aircraft manufacturer, and is widely used by major airlines around the world for long-haul flights. Its size and advanced technology make it a popular choice for airlines looking to transport a large number of passengers efficiently and comfortably.

Explanation
Aspect ratio is a characteristic of an aircraft's wing platform. It is the ratio of the wingspan to the average chord length of the wing. A higher aspect ratio indicates a longer and narrower wing, while a lower aspect ratio indicates a shorter and wider wing. The aspect ratio affects the aircraft's performance, specifically its lift and drag characteristics. Wings with higher aspect ratios generally have lower drag and better efficiency, while wings with lower aspect ratios provide better maneuverability and stability. Therefore, aspect ratio is an important consideration in designing aircraft wings.

Explanation
The given options represent different characteristics of an aircraft dihedral angle. Positive and negative dihedral angles refer to the upward and downward angles of the wings from the horizontal plane. Zero dihedral angle means the wings are parallel to the horizontal plane. However, "One" does not represent any specific characteristic of an aircraft dihedral angle. Therefore, it is not a characteristic of an aircraft dihedral angle.

Explanation
A helicopter is an example of a rotary wing aircraft because it has rotating wings or blades that generate lift and allow it to hover, take off, and land vertically. Unlike fixed-wing aircraft like the taildagger and biplane, which rely on forward motion to generate lift, a helicopter's rotating wings provide the necessary lift and propulsion. An air stabilizer, on the other hand, is not a type of aircraft but a device used to stabilize the flight of an aircraft.

Explanation
Nano aircrafts are the smallest aircraft known because they are designed to be extremely tiny in size. These aircrafts are typically less than a few centimeters in length and are used for various purposes such as surveillance, research, and exploration. Due to their small size, nano aircrafts are able to maneuver in tight spaces and are often equipped with advanced technologies and sensors. They are capable of flying autonomously or being remotely controlled, making them highly versatile and useful in a wide range of applications.

Explanation
The given options are all components that are commonly found in an aircraft. However, "Aird" is not a term or component that is used in aircraft. It is likely a made-up or misspelled word, making it the correct answer as it does not belong to the list of aircraft components.

Explanation
The avionics system of an aircraft is divided into three main divisions. This allows for a more efficient and organized system. Each division is responsible for different functions and components of the avionics system, such as communication, navigation, and surveillance. By dividing the system into three divisions, it ensures that each division can focus on its specific tasks and responsibilities, leading to better overall performance and safety of the aircraft.
