Drone Components And What They Do - Practice

Which of the following is the most likely function of the part labeled "8" in the diagram?

• To capture aerial photos

• To control the drone remotely

• To provide landing support

• To stabilize the camera

If the part labeled "11" in the diagram is damaged, which function of the drone would be most affected?

• The drone's ability to fly

• The drone's ability to capture images or video

• The drone's ability to receive remote commands

• The drone's ability to land safely

What force do propellers generate to allow a drone to fly by counteracting gravity?

• Thrust

• Drag

• Lift

• Friction

Why do two propellers on a drone spin clockwise and two spin counterclockwise?

• To increase speed

• To cancel out torque and prevent continuous spinning (yaw)

• To reduce noise

• To save battery power

What is the main responsibility of propellers on a drone?

• To provide lighting

• To control the camera

• To control the direction and motion of the drone

• To store energy

What could happen if a propeller is faulty before a drone flight?

• The drone will fly faster

• The drone will have impaired flight and a higher chance of an accident

• The drone will use less battery

• The drone will hover in place

Suppose you are preparing your drone for a flight and notice a small crack in one of the propellers. What should you do to ensure safe operation?

• Ignore the crack and fly as usual

• Replace the damaged propeller with an extra one

• Fly at a lower altitude

• Use tape to cover the crack

What materials can UAV propellers be made from?

• Only wood

• Only metal

• Plastic or carbon fiber

• Only glass

If the front right propeller spins counterclockwise, which other propeller will also spin counterclockwise?

• Rear right

• Rear left

• Front left

• All propellers

How does altering the speed of counterclockwise propellers affect the drone?

• It changes the color of the propellers

• It changes the balance of torque, and cause the drone to yaw clockwise (right)

• It increases the size of the drone

• It reduces the number of propellers needed
