I didn't receive my p4 yet, and was hoping someone could explain some things to me. I downloaded the FAA app (B4UFLY). When using that app., and my current location is determined, the "warning action required" symbol appears next to "5 mi from Airports? When you look at the next page, it gives you the name of the airport, and the distance from it, in this example 4.3 mi. The statement above that states "Federal law requires model aircraft operators to notify the airport operator and Air Traffic Control Tower (if one is present) when operating within 5 miles of an airport." My question is, will the p4 operate if you do get permission to fly, or is it preloaded with all airport locations thus preventing you from operating even with permission? Sorry for the long winded question.
