Output of Drone Flight Authorization Check

What is the output of this code that checks if a drone flight is authorized based on altitude and no-fly zone?

Drone Programming

def check_authorization(altitude, in_no_fly_zone):
    if altitude > 400:
        return "Flight not authorized: altitude too high"
    if in_no_fly_zone:
        return "Flight not authorized: no-fly zone"
    return "Flight authorized"

print(check_authorization(350, False))

A "Flight not authorized: altitude too high"

B "Flight authorized"

C "Flight not authorized: no-fly zone"

D "Flight authorized with restrictions"

💡 Hint

Check the altitude and no-fly zone conditions carefully.

The altitude is 350 which is less than 400, and the drone is not in a no-fly zone, so the flight is authorized.

Understanding Drone Weight Categories

According to DGCA rules, which weight category does a drone weighing 3.5 kg belong to?

A Nano drone (less than 250 grams)

B Micro drone (250 grams to 2 kg)

C Small drone (2 kg to 25 kg)

D Medium drone (25 kg to 150 kg)

💡 Hint

Check the weight ranges for each category carefully.

A drone weighing 3.5 kg falls into the Small drone category which is from 2 kg to 25 kg.

Identify the Error in Geo-fencing Code

What error does this code raise when checking if a drone is inside a geo-fenced area?

Drone Programming

def is_inside_geo_fence(lat, lon, fence):
    return fence['lat_min'] <= lat <= fence['lat_max'] and fence['lon_min'] <= lon <= fence['lon_max']

fence = {'lat_min': 12.0, 'lat_max': 13.0, 'lon_min': 77.0}
print(is_inside_geo_fence(12.5, 77.5, fence))

A KeyError: 'lon_max'

B TypeError: unsupported operand type(s) for <=: 'dict' and 'float'

C Returns False

D SyntaxError: invalid syntax

💡 Hint

Check if all required keys exist in the fence dictionary.

The fence dictionary is missing the 'lon_max' key, so accessing it raises a KeyError.

📝 Syntax

Syntax Error in Drone Flight Plan Dictionary

Which option contains the correct syntax for defining a drone flight plan dictionary with keys 'start', 'end', and 'altitude'?

A flight_plan = {'start': (12.9716, 77.5946), 'end': (13.0358, 77.5970), 'altitude': 300}

B flight_plan = {'start': (12.9716, 77.5946), 'end': (13.0358, 77.5970) 'altitude': 300}

C flight_plan = {'start': (12.9716, 77.5946), 'end': (13.0358, 77.5970), 'altitude': 300,}

D flight_plan = {'start': (12.9716, 77.5946), 'end': (13.0358, 77.5970), altitude: 300}

💡 Hint

Check commas and quotes around keys.

Options A and C are correct syntax. Option B misses a comma, Option D misses quotes around 'altitude'.

Calculate Total Flight Time with Battery Constraints

Given a drone with a battery capacity of 6000 mAh and a consumption rate of 1200 mAh per 10 minutes, what is the maximum flight time in minutes?

A 50 minutes

B 60 minutes

C 70 minutes

D 80 minutes

💡 Hint

Divide battery capacity by consumption rate per minute.

Consumption rate is 1200 mAh per 10 minutes = 120 mAh per minute. Total flight time = 6000 / 120 = 50 minutes.
