What Do You Know About Aeronautics And Astronautics? - Quiz

First, aeronautics is a field of study which deals with the ins and outs of air navigation.
Aeronautics includes the understanding, manufacturing and design of machines capable of air flight such as rockets and aircraft, and also the techniques of using them within the atmosphere.
On the other hand, astronautics deals with navigation beyond Earth's atmosphere.

    Which is not an example of aircrafts?

    • A. 

      Airplanes

    • B. 

      Helicopters

    • C. 

      Air balloons

    • D. 

      Airships

    Correct Answer
    C. Air balloons
    Explanation
    Air balloons are not considered aircraft because they do not have a propulsion system and cannot be controlled or maneuvered like airplanes, helicopters, and airships. While they can be used for recreational purposes and provide a means of transportation, they rely on wind currents for movement and lack the ability to navigate in a controlled manner.

  • 3. 

    Which is not a criterion by which aircrafts may be classified?

    • A. 

      Lift type

    • B. 

      Geolocation

    • C. 

      Aircraft propulsion

    • D. 

      Usage

    Correct Answer
    B. Geolocation
    Explanation
    Geolocation is not a criterion by which aircrafts may be classified because it does not define the characteristics or features of an aircraft. The lift type refers to the mechanism used by an aircraft to generate lift, aircraft propulsion refers to the method used to propel the aircraft forward, and usage refers to the purpose or role of the aircraft. However, geolocation does not provide any information about the aircraft's classification or characteristics.

      Skyhawk 337

    • D. 

      Mil-9

    Correct Answer
    A. Cessna 172 Skyhawk
    Explanation
    The Cessna 172 Skyhawk is the most-produced aircraft in history. This is because it has been in production since 1956 and has seen continuous demand from both private pilots and flight training schools. The Cessna 172 is known for its reliability, ease of use, and versatility, making it a popular choice among pilots worldwide. Its long production history and widespread use contribute to its status as the most-produced aircraft in history.

    What do you call the physical air space directly above a location on the ground?

    • A. 

      Aerospace

    • B. 

      Atmosphere

    • C. 

      Airspace

    • D. 

      Stratosphere

    Correct Answer
    C. Airspace
    Explanation
    Airspace refers to the physical air space directly above a location on the ground. It is the area where aircraft operate and includes different types of airspace such as controlled airspace, restricted airspace, and prohibited airspace. This term is used to define and regulate the use of the airspace to ensure safe and efficient air travel. The other options, Aerospace, Atmosphere, and Stratosphere, do not specifically refer to the physical air space directly above a location on the ground.

    Which of these is not an interstellar spacecraft?

    • A. 

      Pioneer 10

    • B. 

      Pioneer 11

    • C. 

      Pioneer 9

    • D. 

      New Horizons

    Correct Answer
    C. Pioneer 9
    Explanation
    Pioneer 9 is not an interstellar spacecraft because it was launched in 1968 and its mission was to study the interplanetary space between Earth and Venus, not to venture beyond our solar system. In contrast, Pioneer 10 and Pioneer 11 were both interstellar spacecrafts that explored the outer regions of our solar system, while New Horizons is a spacecraft that was launched in 2006 with the goal of studying Pluto and the Kuiper Belt.

    Which is the branch of fluid mechanics that deals with flows having significant changes in fluid density?

    • A. 

      Aerodynamics

    • B. 

      Compressible flow

    • C. 

      Transonic flow

    • D. 

      Aerospace engineering

    Correct Answer
    B. Compressible flow
    Explanation
    Compressible flow is the branch of fluid mechanics that deals with flows having significant changes in fluid density. This type of flow occurs when the fluid density changes due to changes in pressure, temperature, or velocity. In compressible flow, the density of the fluid is not constant and can vary significantly. This branch of fluid mechanics is important in various fields such as aerospace engineering, where understanding the behavior of fluids at high speeds and altitudes is crucial.
