A height within a terminal obstacle clearance area, including an initial
approach segment, a departure area, and a circling approach area,
which would result in the vertical distance between any point on the
object and an established minimum instrument flight altitude within
that area or segment to be less than the required obstacle clearance.
A height within an en‐route obstacle clearance area, including turn and
termination areas of a federal airway or approved off‐airway route that
would increase the minimum obstacle clearance altitude.
The surface of a takeoff and landing area of a civilian airport or any
imaginary surface established under 77.19, Department of Defense
(DOD): 77.21, and heliports: 77.2. However, no part of the takeoff or
landing area itself will be considered an obstruction.
Except for traverse ways on or near an airport with an operative
ground traffic control service furnished by an airport traffic control
tower or by the airport management and coordinated with the air
traffic control service, the standards of paragraph (a) of this section
apply to traverse ways used or to be used for the passage of mobile
objects only after the heights of these traverse ways are increased by:
traverse it. The FAA Part 77 Obstruction Evaluation areas for Seymour
Johnson AFB is indicated on Figure 3‐12.
Aircraft Safety Zones
The Air Installation Compatible Use Zone (AICUZ) program was created by the
DOD to identify noise zones and safety zones that can be used by local
communities as land planning tools. The AICUZ program recommends
community land uses compatible with noise levels, accident potentia
