is constructed for and intended to be 
used by propeller driven aircraft of 
12,500 pounds maximum gross weight 
and less. 

Visual runway 

means a runway in-

tended solely for the operation of air-

Subpart B—Notice Requirements 

§ 77.5

Applicability. 

(a) If you propose any construction 

or alteration described in § 77.9, you 
must provide adequate notice to the 
FAA of that construction or alteration. 

(b) If requested by the FAA, you 

must also file supplemental notice be-
fore the start date and upon comple-
tion of certain construction or alter-
ations that are described in § 77.9. 

(c) Notice received by the FAA under 

this subpart is used to: 

(1) Evaluate the effect of the pro-

posed construction or alteration on 
safety in air commerce and the effi-
cient use and preservation of the navi-
gable airspace and of airport traffic ca-
pacity at public use airports; 

(2) Determine whether the effect of 

proposed construction or alteration is 
a hazard to air navigation; 

(3) Determine appropriate marking 

and lighting recommendations, using 
FAA Advisory Circular 70/7460–1, Ob-
struction Marking and Lighting; 

(4) Determine other appropriate 

measures to be applied for continued 
safety of air navigation; and 

(5) Notify the aviation community of 

the construction or alteration of ob-
jects that affect the navigable air-
space, including the revision of charts, 
when necessary. 

§ 77.7

Form and time of notice. 

(a) If you are required to file notice 

under § 77.9, you must submit to the 
FAA a completed FAA Form 7460–1, 
Notice of Proposed Construction or Al-
teration. FAA Form 7460–1 is available 

at FAA regional offices and on the 
Internet. 

(b) You must submit this form at 

least 45 days before the start date of 
the proposed construction or alteration 
or the date an application for a con-
struction permit is filed, whichever is 
earliest. 

(c) If you propose construction or al-

teration that is also subject to the li-
censing requirements of the Federal 
Communications Commission (FCC), 
you must submit notice to the FAA on 
or before the date that the application 
is filed with the FCC. 

(d) If you propose construction or al-

teration to an existing structure that 
exceeds 2,000 ft. in height above ground 
level (AGL), the FAA presumes it to be 
a hazard to air navigation that results 
in an inefficient use of airspace. You 
must include details explaining both 
why the proposal would not constitute 
a hazard to air navigation and why it 
would not cause an inefficient use of 
airspace. 

(e) The 45-day advance notice re-

quirement is waived if immediate con-
struction or alteration is required be-
cause of an emergency involving essen-
tial public services, public health, or 
public safety. You may provide notice 
to the FAA by any available, expedi-
tious means. You must file a completed 
FAA Form 7460–1 within 5 days of the 
initial notice to the FAA. Outside nor-
mal business hours, the nearest flight 
service station will accept emergency 
notices. 

§ 77.9

Construction or alteration re-

quiring notice. 

If requested by the FAA, or if you 

propose any of the following types of 
construction or alteration, you must 
file notice with the FAA of: 

(a) Any construction or alteration 

that is more than 200 ft. AGL at its 
site. 

(b) Any construction or alteration 

that exceeds an imaginary surface ex-
tending outward and upward at any of 
the following slopes: 

(1) 100 to 1 for a horizontal distance 

of 20,000 ft. from the nearest point of 
the nearest runway of each airport de-
scribed in paragraph (d) of this section 
with its longest runway more than
