Research notes

TN airport zoning works in conjunction with FAA Part 77 imaginary surfaces (14 CFR Part 77). Federal conflict check applies — FAA notice of proposed construction (Form 7460-1) is parallel and federal. Major TN airports with AICUZ / Part 77 influence: BNA (Nashville), MEM (Memphis), TYS (Knoxville McGhee Tyson + Air National Guard), CHA (Chattanooga), TRI (Tri-Cities), and military fields including Arnold AFB (Tullahoma).
