Output of a simple drone simulation loop

What is the output of this drone simulation code snippet that runs a safety check loop?

Drone Programming

for i in range(3):
    if i == 2:
        print('Crash detected! Simulation stopped.')
        break
    else:
        print(f'Step {i}: All systems normal.')

A

Step 0: All systems normal.
Step 1: All systems normal.
Crash detected! Simulation stopped.

B

Step 0: All systems normal.
Step 1: All systems normal.
Step 2: All systems normal.

C

Step 0: All systems normal.
Crash detected! Simulation stopped.

D Crash detected! Simulation stopped.

💡 Hint

Look at the loop and the break statement when i equals 2.

The loop prints normal status for i=0 and i=1. When i=2, it detects a crash and stops the simulation with a break.

Why use simulation before real drone flights?

Which of the following is the main reason simulation helps prevent costly crashes in drone programming?

A It makes the drone fly faster in real life.

B It allows testing drone behavior safely without risking hardware damage.

C It replaces the need for any real flight testing.

D It reduces the battery consumption during flights.

💡 Hint

Think about what happens if you test risky code on a real drone.

Simulation lets programmers try out code and detect errors safely, avoiding damage to expensive drones.

Identify the error in this simulation code snippet

What error will this drone simulation code produce when run?

Drone Programming

def simulate_flight(steps):
    for step in range(steps):
        if step == 5:
            print('Emergency stop!')
            break
        print(f'Flying step {step}')
simulate_flight(10)

A SyntaxError due to incorrect assignment operator in if condition.

B No error, prints all steps from 0 to 9.

C NameError because simulate_flight is not defined.

D TypeError because step is not an integer.

💡 Hint

Check the if condition syntax carefully.

The if condition uses '=' which is assignment, not '==' for comparison, causing a SyntaxError.

Output of drone sensor data filtering simulation

What is the output of this code that filters sensor readings above a threshold during simulation?

Drone Programming

sensor_readings = [12, 5, 18, 7, 20]
filtered = [r for r in sensor_readings if r > 10]
print(filtered)

A []

B [5, 7]

C [12, 5, 18, 7, 20]

D [12, 18, 20]

💡 Hint

Look for readings greater than 10.

Only readings 12, 18, and 20 are greater than 10, so they appear in the filtered list.

Why simulation reduces overall drone project costs

Which statement best explains how simulation reduces costs in drone projects?

A Simulation makes drones fly longer on a single battery charge.

B Simulation replaces the need for any hardware, so no drones are ever bought.

C Simulation allows early detection of software bugs, preventing expensive hardware damage and repeated repairs.

D Simulation automatically fixes all drone software errors without human input.

💡 Hint

Think about the cost of fixing problems after a crash versus before.

By finding bugs early in simulation, developers avoid crashes that can damage drones and increase costs.
