I did something hilarious today: I asked ChatGPT to build me a flight plan. You can see the conversation here, and as you can see, it did a pretty decent job: it mentioned sights along the route, gave me all relevant radio frequencies, and had general remarks at hand. It also briefed an alternate airport, as well as an estimate for the time needed for the whole trip.
Actually the conversation was much longer, as I asked it to also suggest some VORs and change the flight plan accordingly.
So if you ever run out of ideas, as your friendly neighborhood AI.
