Width of runway safety area | 150 ft |
Width of runway | 40 ft |
Maximum effective gradient | 2% |
Slope of Approach Surface | 20:1 |
*Minimum length increased 10 % for each I of effective gradient. |
(b)

(c)
Facilities
1. Office of Aeronautics approved
markers shall be installed on unpaved landing areas at 200 foot intervals along
the useable width and at 150 foot intervals at the ends of the landing
area.
2. Office of Aeronautics
approved wind indicator must be installed.
3. A fire extinguisher which is capable of
extinguishing all classes of fire must be available for immediate
use.
4. An Office of Aeronautics
approved runway lighting system must be installed prior to approval for
nighttime operations.
(d) Miscellaneous
1. Airport hazards as determined by the
Office of Aeronautics must be marked and must also be lighted if the airport is
approved for nighttime operation.
2. The licensee shall notify the Office of
Aeronautics in writing whenever alternations, improvements, or major repairs
are to be accomplished on the airport.
3. The landing area, taxiways, and ramp area
must be maintained in such a manner as to assure the sate operation of
aircraft.
4. The owner of a closed
or abandoned airport shall remove all airport identifying markers and wind
indicators and shall place upon the runway an approved "Closed" marker. This
marker shall be maintained until the runway is no longer
identifiable.
(2) Sub-paragraph B - Heliports
(a) Definitions:
1. | Heliport | An area, either at ground level or elevated on a structure, that is used for the landing and taking off of helicopters. |
2. | Landing and Takeoff Area | That specific area in which the helicopter actually lands and takes off, including the touchdown area. |
3. | Touchdown Area | That part of the landing or takeoff area where it is preferred that the helicopter alight. |
4. | Peripheral Area | A safety zone that provides an obstruction-free area on all sides of the landing and takeoff area. |
5. | Obstruction Clearance Plane | Imaginary planes leading outward and upward from the take-off and landing area at angles compatible with the flight characteristics of the helicopter and type of operations anticipated. |
(b)
Dimensions (See Figure 2)
Landing and Takeoff Area | 50 ft. x 50 ft. |
Touchdown Area | 20 ft. x 20 ft. |
Peripheral Area Width | 10 ft. |
Obstruction Clearance Slope | 8:1 |
(c)
Facilities
1. Office of Aeronautics approved
wind indicator must be installed.
2. A fire extinguisher which is capable of
extinguishing all classes of fire must be immediately available.
3. All heliports shall be marked with
standard heliport or hospital heliport markings approved by the Office of
Aeronautics. Markings shall be painted on paved or concrete surfaces; patio
stones painted suitable colors may be used on turf areas.
4. An Office of Aeronautics approved lighting
system must be installed proper to approval for nighttime operations.
(d) Miscellaneous
1. Obstructions as determined by the Office
of Aeronautics must be marked and must also be lighted if the airport is
approved for nighttime operations.
2. The licensee shall notify the Office of
Aeronautics in writing whenever alterations, improvements, or major repairs are
to be made.
3. The landing area
must be maintained so as to assure safe operations.
(3) Subparagraph C - Seaplane
Bases
(a) Since the length of waterway
necessary for seaplanes varies greatly depending on the airplane types, the
purpose of this subsection will only be to specify that each seaplane base must
be judged individually with regard to the type of seaplanes using the facility.
However, in no case, will approach-departure paths be less than a 20:1
slope.
(b) Facilities
1. Office of Aeronautics approved wind
indicator must be installed.
2. A
fire extinguisher which is capable of extinguishing ail classes of fire must be
available for immediate use.
3. At
least three life preservers of the ring or throwing type, with line attached to
each, shall be available during hours of operation.
4. The minimum water depths and landing area
lengths shall be posted at the docking or beaching area.
(c) Miscellaneous
1. Airport hazards as determined by the
Office of Aeronautics must be marked.
2. No seaplane base shall be approved which
requires aircraft to operate in close proximity to a bridge, public beach,
power line, boat dock or other area which could constitute a danger to persons
or property.
3. No seaplane base
shall be approved on the navigable waters of Tennessee unless a permit is first
obtained from the U.S. Army Corps of Engineers or the Tennessee Valley
Authority, as appropriate. Additionally, proof of a lease or ownership of the
needed land adjacent to the water areas of the base is required.
