Interesting to see this topic today. I was awakened this morning by the
sound of an airplane. When my wife and I looked out the window we observed
that our closest neighbor (half a mile away) was having one of his wheat
fields airdusted for weeds. The plane was flying directly over our house as
he made each foray over the field across the road. I looked as he made
several passes extremely close to my tower (45G with the owl at about 100').
I snapped a picture of him from an angle that made it look like he was
flying directly into the tower. I was a little uneasy, but those air spray
dudes fly within 6 inches of the power lines all the time so I figured if he
could see them, surely he could see my tower with 6 yagis up and down it.
I'm about 20 miles from the airport so I know I'm legal, but I find it
coincidental to see this thread today.

This matter is covered in "Antenna Zoning for the Radio Amateur,"
published by the ARRL. A quick start is to go to the FCC web page and
search for "towair". The checklist you remember has been supplemented and
is now truly an excellent piece of government work, serving the public.
Here's a paragraph I have prepared for submission to a city on Wednesday
(which is why I just happened to have it handy).
Separately, we have provided 10 copies of FAA Advisory Circular AC
70/7460-1J: ?Obstruction Marking and Lighting? (Source:
http://www.faa.gov/ATS/ATA/ai/index.html), and 10 copies of FAA Advisory
Circular AC 70/7460?2J: ?Proposed Construction or Alteration of Objects
that May Affect the Navigable Airspace.? See especially ?Obstruction
Marking and Lighting,? page A1-12-13, and A2-1. An additional Advisory
Circular 150/5345-43E ?Specification for Obstruction Lighting Equipment,?
may be found at http://ntl.bts.gov/data/5345-43e.pdf.
The actual Federal regulations may be found at 14 CFR Part 77.1 through
