Purpose.

This part establishes:
(a) The requirements to provide notice to the FAA of certain proposed
construction, or the alteration of existing structures;
(b) The standards used to determine
obstructions to air navigation, and
navigational and communication facilities;
(c) The process for aeronautical studies of obstructions to air navigation or
navigational facilities to determine the
effect on the safe and efficient use of
navigable airspace, air navigation facilities or equipment; and

(d) The process to petition the FAA
for discretionary review of determinations, revisions, and extensions of determinations.
Section 77.3 Definitions.
For the purpose of this part:
Non-precision
instrument
runway
means a runway having an existing instrument approach procedure utilizing
air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in
non-precision
instrument
approach
procedure has been approved, or
planned, and for which no precision approach facilities are planned, or indicated on an FAA planning document or
military service military airport planning document.
Planned or proposed airport is an airport that is the subject of at least one
of the following documents received by
the FAA:
(1) Airport proposals submitted under
14 CFR part 157.
(2) Airport Improvement Program requests for aid.
(3) Notices of existing airports where
prior notice of the airport construction
or alteration was not provided as required by 14 CFR part 157.
(4) Airport layout plans.
(5) DOD proposals for airports used
only by the U.S. Armed Forces.
(6) DOD proposals on joint-use (civilmilitary) airports.
(7) Completed airport site selection
feasibility study.
Precision instrument runway means a
runway having an existing instrument
approach procedure utilizing an Instrument Landing System (ILS), or a Precision Approach Radar (PAR). It also
means a runway for which a precision
approach system is planned and is so
indicated by an FAA-approved airport
layout plan; a military service approved military airport layout plan;
any other FAA planning document, or
military service military airport planning document.
Public use airport is an airport available for use by the general public without a requirement for prior approval of
the airport owner or operator.
Seaplane base is considered to be an
airport only if its sea lanes are outlined by visual markers.
