Phantom 4 Advanced flyaway

it was also above the legal altitude unless you had a permit or were flying above a tall building, over 300 feet tall... and no mention of ATC notification...

The OP has since clarified that the flight was fully authorized. It pays to read the entire thread before commenting.

Pattern altitude in US is basically 1000 AGL. So if airport is 100’MSL, That makes pattern altitude 1100’MSL. That’s the general fixed wing aircraft altitude unless otherwise noted by Sectional or NOTAM. Rotary wing aircraft have different pattern altitude...as they don’t typically fly the pattern.
