Any flight above the tree line, yes. If I'm using the Spark for a Selfie, for a close shot 15 ft up, I don't call.
Common sense prevails. I have 2 'helipads' by my house that haven't been used in 30 years...
The contact phone #s don't work, but the FAA still keeps it active on maps... control freaks.
One of the helipads was on an estate, which was sold to a developer, and a subdivision was built there.
The other one is marked on a golf course fairway. Do some investigating... not everything on airmap is 'legit'.
Fact is, as a responsible pilot, in a new area, you SHOULD CALL if you're within 5 miles, because YOU
have no idea how active those local airstrips/helipads are. I've never been shunned by any airport
personnel for calling... only thanked. It gets fun when you're in 3 airport zones... but, iffin' ya wanna
fly, it's best to have the law on YOUR side.
