Horizontal Surface
150’ above airport elevation for 5,000-10,000’
Conical Surface
Begins at edge of horizontal surface: rises at 20:1 for 4,000’

16. Still – What’s a Guy/Gal to Do?
Where zoning exists
Educate building permit officials of Part 77 requirements
Ensure that permits are not issued without 7460 submittal
Where zoning does not exist
