VFR stands for Visual Flight Rules, meaning that pilots must navigate visually when operating under those conditions. Visual navigation requires certain atmospheric visibility and the ability to maintain clearance from clouds. While the specific VFR minima vary by country and airspace type, the atmospheric visibility must generally be greater than 3 NM and pilots must be able to remain 500 feet below, 1,000 feet above, and 2,000 feet laterally from clouds.
You can use many options when it comes to planning your VFR flight. There are paid programs such as Navigraph or free browser based software such as Simbrief to name a couple.
You can use Microsoft Flight Simulator to create your VFR flight by going to World Map and selecting your Departure and Destination Airports and selecting either “VFR (Direct-GPS)” or “VFR (VOR-TO-VOR)”.
