Flight Following is the VFR equivalent of IFR flight instructions and tower guidance. It usually includes flight vectors, weather information, traffic calls, and constant updates via radio from the nearest ATC (Air Traffic Control) facility. It’s the next best thing to radar and far cheaper and easier to use than having to qualify as an IR (Instrument Rated) pilot and investing in, and flying an IFR airplane.
The best and most effective way to request Flight Following from any ATC facility is to simply ask for it. Just open the appropriate radio channel and start talking to the nearest ATC facility and providing you request Flight Following in a friendly, polite, and appropriate manner, they will be more than happy to comply and service and supply you with all of the information that you need.
