IndexError: list index out of range
#11
First of all - sorry to tell you, but you are doing it wrong.
get_flight() returns a list of FlightRadar24.flight.Flight objects. Every object has methods and you can access them, no need for all this complication to convert to string and then parse it.

import csv
from datetime import datetime
from FlightRadar24.api import FlightRadar24API
fr_api = FlightRadar24API()
 
flights = fr_api.get_flights(airline = 'AZU')
print(type(flights[0]))
print(flights[0].__dict__)

with open('fr24.csv', 'w') as f:
    fieldnames = ['time', 'aircraft_code', 'registration', 'altitude', 'ground_speed', 'heading'] # you can include whatever attributes you want
    wrtr = csv.DictWriter(f, fieldnames=fieldnames, extrasaction='ignore')
    wrtr.writeheader()
    for flight in flights:
        flight.time = datetime.fromtimestamp(flight.time) # convert the timestamp to datetime object
        wrtr.writerow(flight.__dict__) # here I pass all attributes as dict, but you can always access individual attributes, like I did with time above
the output

Output:
<class 'FlightRadar24.flight.Flight'> {'id': '273002c6', 'icao_24bit': 'E495B3', 'latitude': -23.6238, 'longitude': -46.6602, 'heading': 236, 'altitude': 0, 'ground_speed': 4, 'squawk': '5107', 'aircraft_code': 'A20N', 'registration': 'PR-YSE', 'time': 1616685581, 'origin_aiport_iata': 'REC', 'destination_airport_iata': 'CGH', 'number': 'AD4251', 'airline_iata': 'AD', 'on_ground': 1, 'vertical_speed': 0, 'callsign': 'AZU4251', 'airline_icao': 'AZU'}

Now, I didn't look into details - e.g. iz it possible to retrieve info for multiple companies or you need to make separate requests, but you get the idea.
Also, if you are going to scrap large amount of information - maybe it's better to look at some database, e.g. sqlite3 support comes with python standard library. Also consider that API can blok you if you are heavy on them - check their allowed limits.

Finally - maybe you need to take some tutorial/course, incl. about objects, OOP, etc.

Until you've done this three times:
    for i in range(0,len(empresas)):
        nav.append(len(fr_api.get_flights(airline = empresas[i])))
It is difficult to say how such a thing is accomplished since it depends as much on what the program does as the nuts and bolts of coding the program so it doesn't crash. Right now all I have to work with is some code that doesn't work. it is difficult to know how to fix it unless I know what it is SUPPOSED to do.

What does this line do?
n_acft_voando = [dia, hora, nav[0], nav[1], nav[2]]
[/python]
Why does in need nav[0], nave[1] and nav[2]? What are nav[0], nav[1] and nav[2]?
I find it suspicious that these indices are hard coded when the outer loop may run more than 3 times based on this:
    empresas = ['AZU', 'GLO', 'LAN']
    #, 'JBU', 'AAL', 'DAL', 'ACA', 'UAL'
Is this a hint that empresas may be a larger list?. If so, maybe the proper way to code this is:
    for i in range(2):
        nav.append(len(fr_api.get_flights(airline = empresas[i])))

    for i in range(2,len(empresas)):
        nav.append(len(fr_api.get_flights(airline = empresas[i])))
        dados_voo = fr_api.get_flights(airline = empresas[i])
 
        for k in range (0,len(dados_voo)):
            substring = re.search(pattern, str(dados_voo[k])).group(1)
            substring = substring.split(' - ')
            modelo_tail = [x.replace(" ", ";") for x in substring]
            n_acft_voando = [dia, hora, nav[i-2], nav[i-1], nav[i]]
            acft_voando=[dia, hora, modelo_tail[0]]
            print(acft_voando)
 
            with open(r'C:\Users\bruno\Desktop\Voos\DB\AeronavesAr.txt', 'a', newline='') as f:
                writer = csv.writer(f, delimiter=';')
                writer.writerow(n_acft_voando)
 
            with open(r'C:\Users\bruno\Desktop\Voos\DB\DetalhesAeronaves.txt', 'a', newline='') as f:
                writer = csv.writer(f, delimiter=';')
                writer.writerow(acft_voando)
Again, I don't know if this is correct.

YOU ARE THE BEST!
THANK YOU SO MUCH!!!
