I understand this is a sore subject for many, mainly due to the cost involved, but in my thinking, if you want to be a pilot of a craft in the NAS you should know the intricacies of the airspace system. There is no better way to learn than to earn your PPL. This is conservative because actually, your commercial certificate at 250 hrs should allow you to be paid for operations in US airspace. Why are we okay with individuals and businesses being compensated for work when they have no clue as to how air traffic flows? These are honest feelings and questions I have, not meant to belittle anyone, but are meant to bring about thought to what sUAS integration means for the future.
