Hello All, Last week, I made my longest cross country flights yet (6.7 hours hobbs each way). I got some experience with FF and a couple of class D towers. It was great! This weekend, I am planning a shorter flight (under 2 hours) to my first class C airport (KBIL). So, I am wondering from a practical standpoint, how much different do I need to prepare for operating there vs a Class D airport? Any tips appreciated!
