Make sure you pull up the chart supplements for the airports near your operating areas to learn more about them. You might be pleasantly surprised that the airspace changes when the airport is not in operation. I was concerned about the airport (KHUA) with Class D airspace near me because it does reach out into a significant portion of the city that I live and do business in. See below: I got the idea to pull up the chart supplement mainly just to see when their ATC was open. Luckily, I noticed that the airspace changes from Class D to Class G after 2130Z, or 4:30pm local time on Monday-Friday and during weekends and holidays. That's perfect for me, because I do work a full time day job and try to do my shoots during the weekend or late afternoons. Now I just need to keep an eye out for NOTAMs, fly when it's Class G, and I don't have to go through the process of requesting airspace authorization. So those of you who are wondering about your nearby airports, doublecheck your chart supplements!
