Recognizing the TFRs are there for a reason, and also recognizing the impact on pilots during the time frame. Just exactly how would a
MA or Spark detect NFZ during, i.e., Presidential visit, (campaign trips will be forth coming) without firmware update? The DJI Spark is capable of flight with just the remote and drone (without phone or view device). Without a firmware update, could a pilot not fly the Spark with just remote controller, not being aware of temp NFZ? Is there some sort of a special signal broadcast by FAA? to inform all pilots, within specified radius, of the NFZ during Presidential operations. Also, realizing the importance of checking NOTAMS, many drone pilots would not even attempt that.
How does the NFZ system work, to notify drone pilots without using an FW update?
