The Physics Behind Flight

Newton’s _______ Law: Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it.

Answer explanation

•  

  A turn coordinator provides an indicator of the:

• 
  Angle of bank up to but not exceeding 30°.

• Attitude of the aircraft with reference to the longitudinal axis.

• Movement of the aircraft about the yaw and roll axes.

Answer explanation

The turn coordinator provides an indicator of the movement of the aircraft about the yaw and roll axes. This means that it shows the aircraft's rotation around the vertical axis (yaw) and the rotation around the longitudinal axis (roll). It does not provide information about the angle of bank, which is the angle between the aircraft's wings and the horizon. It also does not indicate the attitude of the aircraft with reference to the longitudinal axis, which refers to the aircraft's pitch or nose-up/nose-down position.

9. The part of the airplane that is used to control the up-and-down movement of the nose of the airplane is labelled by the letter.

  An airplane will stall at the same:

• Angle of attack and altitude with relation to the horizon

• Airspeed regardless of the altitude with relation to the horizon

• Angle of attack regardless of the altitude with relation to the horizon

Answer explanation

• The correct answer is "angle of attack regardless of the altitude with relation to the horizon." The angle of attack refers to the angle between the wing's chord line and the oncoming airflow. It determines the lift and drag forces acting on the aircraft. Regardless of the altitude, the angle of attack at which an airplane stalls remains the same. This means that if the angle of attack exceeds the critical value, the airflow over the wings becomes disrupted, causing a loss of lift and a stall. Airspeed and altitude do not directly affect the angle of attack at which a stall occurs.
