    Which of these things affects the stall speed?

    • Total weight

    • Load factor

    • The location of the center of gravity

    • All of these

    Correct Answer
    A. All of these
    Explanation
    All of these factors affect the stall speed of an aircraft. The stall speed is the minimum speed at which an aircraft can maintain level flight. Total weight affects the stall speed because a heavier aircraft requires a higher speed to generate enough lift to counteract the weight. Load factor, which is the ratio of the lift force to the weight of the aircraft, also affects the stall speed as it determines the amount of lift produced. The location of the center of gravity is important because it affects the stability and control of the aircraft, which in turn affects the stall speed.

    If the speed of the airplane is faster,

    • The less lift it will cause

    • The more lift it will cause

    • The lift will not be affected

    • The lift will be zero

    Correct Answer
    A. The more lift it will cause
    Explanation
    As the speed of an airplane increases, it causes more lift. This is because lift is directly proportional to the speed of the airplane. As the speed increases, the air flowing over the wings increases, creating more lift. Therefore, the correct answer is "The more lift it will cause."

    What controls the motion of the airplane for longitudinal stability?

    • Rudder

    • Ailerons

    • Windows

    • Elevator

    Correct Answer
    A. Elevator
    Explanation
    The elevator controls the motion of the airplane for longitudinal stability. The elevator is located on the horizontal tail surface of the airplane and it is responsible for controlling the pitch motion of the aircraft. By changing the angle of the elevator, the pilot can control the nose-up or nose-down attitude of the airplane, which helps maintain stability during flight. This control surface is crucial for maintaining the desired altitude and preventing the airplane from pitching uncontrollably.

    Stall speed is affected by:

    • Weight, load factor, and power

    • Load factor, angle of attack, and power

    • The angle of attack, weight, and air density

    • The angle of attack, load factor, and air density

    Correct Answer
    A. Weight, load factor, and power
    Explanation
    Stall speed is the minimum speed at which an aircraft can maintain level flight. It is affected by several factors, including weight, load factor, and power. Weight plays a significant role as a heavier aircraft will require a higher speed to generate enough lift to counteract its weight. Load factor, which is the ratio of the lift force to the aircraft's weight, also affects stall speed. Higher load factors increase the stall speed. Additionally, power is a crucial factor as it determines the thrust produced by the engines, which affects the aircraft's ability to maintain level flight and avoid stalling.

    An airplane leaving ground effect will:

    • Experience a reduction in ground friction and requires a slight power reduction.

    • Experience an increase in induced drag and require more thrust.

    • Requires a lower angle of attack to maintain the same lift coefficient.

    • None of these is true.

    Correct Answer
    A. Experience an increase in induced drag and require more thrust.
    Explanation
    When an airplane leaves ground effect, it moves away from the ground and the cushioning effect of the air trapped between the airplane and the ground is lost. This results in a decrease in lift and an increase in induced drag. To compensate for the increased drag, the airplane requires more thrust. Therefore, the correct answer is that an airplane leaving ground effect will experience an increase in induced drag and require more thrust.

    Rate this question:

  • 7. 

    What does the plane need to have the same lift while it is in ground effect?

    • A lower angle of attack

    • The same angle of attack

    • A greater angle of attack

    • Zero angle of attack

    Correct Answer
    A. A lower angle of attack
    Explanation
    When an aircraft is in ground effect, it experiences a cushioning effect due to the ground surface. This effect reduces the downwash and increases the lift generated by the wings. To maintain the same lift while in ground effect, the plane needs a lower angle of attack. A lower angle of attack reduces the drag and allows the aircraft to maintain the same lift force with less resistance.

    What happens when the load factor is zero?

    • All occupants feel heavy.

    • All occupants feel the heaviest.

    • All occupants feel weightless.

    • None of these is true.

    Correct Answer
    A. All occupants feel weightless.
    Explanation
    When the load factor is zero, it means that there is no force acting upon the occupants. In this case, they would feel weightless because there is no gravitational force or any other force pushing or pulling them in any direction. This is similar to the feeling of weightlessness experienced by astronauts in space where they are not influenced by the Earth's gravity.

    Transonic airflow typically occurs in airplane speed regimes between Mach

    • 0.75 and 0.95

    • 0.95 and 1.01

    • 0.8 and 1.2

    • 1.3 and 2.1

    Correct Answer
    A. 0.8 and 1.2
    Explanation
    Transonic airflow refers to the speed regime in which an aircraft is approaching the speed of sound. It occurs between Mach 0.8 and 1.2, which means that the aircraft is traveling at speeds between 80% and 120% of the speed of sound. In this regime, the airflow around the aircraft becomes highly turbulent and can cause significant drag and control issues. Therefore, it is important for aircraft designers and pilots to understand and account for transonic airflow when operating in this speed range.

    Rate this question:

  • 10. 

    What happens as the airplane goes beyond the critical Mach number?

    • The drag coefficient increases to the highest.

    • The drag coefficient drops down to zero.

    • There is a sudden decrease in the drag coefficient.

    • There is a sudden increase in the drag coefficient.

    Correct Answer
    A. There is a sudden decrease in the drag coefficient.
    Explanation
    As the airplane goes beyond the critical Mach number, there is a sudden decrease in the drag coefficient. This is because the critical Mach number is the speed at which the airflow over certain parts of the aircraft reaches the speed of sound. Beyond this point, the airflow becomes supersonic, causing a decrease in drag due to the shockwaves that form. This sudden decrease in drag coefficient allows the aircraft to fly faster with less resistance.
