Okla. Stat. tit. 3, § 3-120.2

As used in the Aircraft Pilot and Passenger Protection Act:

1. "Airport reference point" is the geometrical center of all

usable runways;

2. "Airport elevation" is the highest point of an airport's

usable runways measured in feet from mean sea level;

3. "Approach surface" is an imaginary surface shaped like a

trapezoid:

a. longitudinally centered on the extended runway

centerline at a public-use airport,

b. beginning two hundred (200) feet beyond the end of

each runway pavement and at the runway end elevation,

c. having an inner-edge width of one thousand (1,000)

feet expanding outward uniformly to a width of sixteen

thousand (16,000) feet at the outer edge, and

d. sloping upward for a distance of ten thousand (10,000)

feet at a slope of fifty (50) to one (1), with an

additional forty thousand (40,000) feet at a slope of

forty (40) to one (1);

4. "Commission" means the Oklahoma Aeronautics Commission or a

successor agency;

5. "Conical surface" is an imaginary surface extending outward

and upward from the periphery of the horizontal surface at a slope

of twenty (20) to one (1) for a horizontal distance of four thousand

(4,000) feet;

6. "FAA" means the Federal Aviation Administration or a

successor agency to the Federal Aviation Administration;

7. "Horizontal surface" is an imaginary horizontal plane one

hundred fifty (150) feet above the established airport elevation,

the perimeter of which is constructed by swinging arcs of ten

thousand (10,000) feet radii from a point located on the extended

runway centerline two hundred (200) feet beyond each end of runway

pavement and connecting the adjacent arcs by lines tangent to those

arcs;

8. "Incompatible purpose" means the use of a building,

structure or area as a residence, educational center (including all

types of primary and secondary schools, preschools, and child-care

facilities), place of worship, place of public assembly, hospital,

medical inpatient treatment facility, nursing/convalescent home,

retirement home, transportation facility, storage facility,

aboveground utility facility or similar use;

9. "Legal representative" means a person who is authorized to

legally bind an entity;

10. "Permit" means a permit issued by the Commission under this

act;

11. "Person" means an individual, firm, partnership,

corporation, association, or body politic and includes a trustee,

receiver, assignee, or other similarly authorized representative of

any of them;

12. "Primary surface" is a surface longitudinally centered on a

runway. When the runway has a specially prepared hard surface, the

primary surface extends two hundred (200) feet beyond each end of

that runway; but when the runway has no specially prepared hard

surface, or planned hard surface, the primary surface ends at each

end of that runway. The elevation of any point on the primary

surface is the same as the elevation of the nearest point on the

runway centerline. The width of the primary surface is one thousand

(1,000) feet;

13. "Public-use airport" means a structure or an area of land

or water that is designed and set aside for the landing and taking

off of aircraft, is utilized or to be utilized by and in the

interest of the public for the landing and taking off of aircraft

and is identified by the FAA as a public-use airport. Public-use

airport shall include any military airport operated by a branch of

the armed services of the United States government. Public-use

airport shall not include any privately owned airport for private

use as identified by the FAA, or any airport owned by a municipality

with a population exceeding five hundred thousand (500,000)

according to the most recent Federal Decennial Census;

14. "Runway" means the portion of an airport designated as the

area used for the landing or takeoff of aircraft;

15. "Runway protection zone" is a trapezoidal zone centered
y privately owned airport for private

use as identified by the FAA, or any airport owned by a municipality

with a population exceeding five hundred thousand (500,000)

according to the most recent Federal Decennial Census;

14. "Runway" means the portion of an airport designated as the

area used for the landing or takeoff of aircraft;

15. "Runway protection zone" is a trapezoidal zone centered

along the extended runway centerline, beyond each end of the primary

surface, two thousand five hundred (2,500) feet long, with an inner

width of one thousand (1,000) feet and an outer width of one

thousand seven hundred fifty (1,750) feet. The function of the

runway protection zone is to enhance the protection of people and

property on the ground;

16. "Structure" means any constructed or installed object

including, but not limited to, buildings, towers, wind turbines,

smokestacks, electronic transmission or receiving towers, and

antennae and overhead transmission lines. The term does not

include:

a. any aviation navigational aids that are fixed by

function, or

Oklahoma Statutes - Title 3. Aircraft and Airports Page 77

b. any construction or installed object on property owned

by the federal government; and

17. "Total structure height" means the elevation of the ground

above mean sea level at the structure's location, plus the height of

the structure above ground level in feet, plus the applicable survey

type adjustment provided the survey adjustment is in accordance with

Federal Aviation Administration standards.
