Does anyone know what the regulation is for flying in squares that have more than one controlling agency? Does one need to get permission from all the airports that control that same airspace to fly in that specific square; or just one?
For example there are many squares in the DFW area that include three different airports in the same square--like Addison, Love Field and DFW. I have a Wide Area Authorization for both Addison and DFW. I do not have one for Love Field, and currently the LAANC system is temporarily not available for Love Field.
So, if a square has Love Field as an associated airport, but also has DFW and / or Addison ALSO as an associated airport; does that mean I can fly there, since I have authorization for two of the other airports... or do I need authorization from all three?
