Multiple choice

Which of the following is a commonly used method for attitude determination of spacecraft?

  1. Kalman Filter

  2. Extended Kalman Filter (EKF)

  3. Unscented Kalman Filter (UKF)

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Kalman Filter, Extended Kalman Filter (EKF), and Unscented Kalman Filter (UKF) are commonly used methods for attitude determination of spacecraft, providing optimal estimates of the spacecraft's attitude based on sensor measurements and system models.

  1. 100 feet (30 meters)

  2. 200 feet (60 meters)

  3. 400 feet (120 meters)

  4. 800 feet (240 meters)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In most countries, the recommended maximum altitude for flying drones is 400 feet (120 meters).

Multiple choice

What is the primary factor that determines the amount of lift generated by an aircraft's wing?

  1. The angle of attack of the wing

  2. The speed of the aircraft

  3. The density of the air

  4. The shape of the wing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The angle of attack of the wing is the angle between the wing's chord line and the relative wind. The greater the angle of attack, the more lift is generated by the wing.

Multiple choice

What is the primary factor that determines the amount of drag generated by an aircraft?

  1. The shape of the aircraft

  2. The speed of the aircraft

  3. The density of the air

  4. The angle of attack of the wing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The shape of the aircraft is the primary factor that determines the amount of drag generated by the aircraft. A streamlined shape will generate less drag than a blunt shape.

Multiple choice

What is the term used to describe the point at which the lift generated by an aircraft's wing is equal to the weight of the aircraft?

  1. Stall

  2. Cruise

  3. Takeoff

  4. Landing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cruise is the term used to describe the point at which the lift generated by an aircraft's wing is equal to the weight of the aircraft. This is the point at which the aircraft is flying at a constant speed and altitude.

Multiple choice

What is the term used to describe the point at which an aircraft's wing no longer generates enough lift to keep the aircraft in the air?

  1. Stall

  2. Cruise

  3. Takeoff

  4. Landing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Stall is the term used to describe the point at which an aircraft's wing no longer generates enough lift to keep the aircraft in the air. This can be caused by a number of factors, including a high angle of attack, a low airspeed, or a change in the shape of the wing.

Multiple choice

What is the term used to describe the phenomenon in which an aircraft loses control due to a sudden change in airflow over the wings?

  1. Stall

  2. Spin

  3. Turbulence

  4. Wake turbulence
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A spin is a phenomenon in which an aircraft loses control due to a sudden change in airflow over the wings. This can be caused by a number of factors, including a high angle of attack, a low airspeed, or a change in the shape of the wing.

Multiple choice

What is the term used to describe the phenomenon in which an aircraft experiences a sudden loss of altitude due to a change in air density?

  1. Stall

  2. Spin

  3. Turbulence

  4. Wake turbulence
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Turbulence is a phenomenon in which an aircraft experiences a sudden loss of altitude due to a change in air density. This can be caused by a number of factors, including wind shear, updrafts, and downdrafts.

Multiple choice

What is the term used to describe the phenomenon in which an aircraft experiences a sudden loss of altitude due to the wake of another aircraft?

  1. Stall

  2. Spin

  3. Turbulence

  4. Wake turbulence
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wake turbulence is a phenomenon in which an aircraft experiences a sudden loss of altitude due to the wake of another aircraft. This can be caused by a number of factors, including the size of the aircraft, the speed of the aircraft, and the distance between the aircraft.

Multiple choice

What is the term used to describe the phenomenon in which an aircraft experiences a sudden change in altitude due to a change in wind direction?

  1. Stall

  2. Spin

  3. Turbulence

  4. Wind shear
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind shear is a phenomenon in which an aircraft experiences a sudden change in altitude due to a change in wind direction. This can be caused by a number of factors, including the presence of mountains, buildings, or other obstacles.
