14 CFR Ch. I (1–1–19 Edition) 

§ 151.13 

standard configuration, length, and 
property interests, considering all facts 
presented by the airport owner or oper-
ator. Any development that improves a 
specific runway or landing strip is con-
sidered to be a runway improvement, 
including runway lighting and the de-
veloping or lighting of taxiways serv-
ing a runway. 

(e) On existing airports where sub-

stantial improvements are made that 
do not benefit a specific runway or 
landing strip, such as overall grading 
or drainage, terminal area or building 
developments, the sponsor must own, 
acquire, or agree to acquire adequate 
property interests in runway clear zone 
areas for the dominant runway or land-
ing strip to the extent that the Admin-
istrator determines is practical and 
feasible, with regard to standard con-
figuration, length, and property inter-
ests, considering all facts presented by 
the airport owner or operator. 

(f) If a sponsor or other public agency 

shows that it is legally able to prevent 
the future erection or creation of ob-
structions in the runway clear zone 
area, and adopts protective measures 
to prohibit their future erection or cre-
ation, that showing is acceptable for 
the purposes of paragraphs (d) and (e) 
of this section in place of an adequate 
property interest (except for rights re-
quired for removing existing obstruc-
tions). In such a case, there must be an 
agreement between the FAA and the 
sponsor for removing or marking or 
lighting (to be determined in each 
case) any existing obstruction to air 
navigation In each case, the sponsor 
must furnish information as to the spe-
cific height limitations established and 
as to the current and foreseeable future 
use of the property to which they 
apply. The information must include 
an acceptable legal opinion of the va-
lidity of the measures adopted, includ-
ing a conclusion that the height limi-
tations are not unreasonable in view of 
current and foreseeable future use of 
the property, and are a reasonable ex-
ercise of the police power, together 
with the reasons or basis supporting 
the opinion. 

(g) The authority exercised by the 

Administrator under paragraphs (b), 
(c), (d), and (e) of this section to allow 
a deviation from, or the extent of con-

formity to, standard configuration or 
length of runway clear zones, or to de-
termine the adequacy of property in-
terests therein, is also exercised by Re-
gional Directors.

§ 151.13

Federal-aid Airport Program: 

Policy affecting landing aid re-
quirements. 

(a) 

Landing aid requirements. 

No 

project for developing or improving an 
airport may be approved for the Pro-
gram unless it provides for acquiring or 
installing such of the following landing 
aids as the Administrator determines 
are needed for the safe and efficient use 
of the airport by aircraft, considering 
the category of the airport and the 
type and volume of traffic using it: 

(1) Land needed for installing ap-

proach lighting systems (ALS). 

(2) In-runway lighting. 
(3) High intensity runway lighting. 
(4) Runway distance markers. 

For the purposes of this section ‘‘ap-
proach lighting system (ALS)’’ is a 
standard configuration of aeronautical 
ground lights in the approach area to a 
runway or channel to assist a pilot in 
making an approach to the runway or 
channel. 

(b) 

Specific landing aid requirements. 

The landing aids set forth in para-
graphs (a) (1) through (4) of this section 
are required for the safe and efficient 
use of airports by aircraft in the fol-
lowing cases: 

(1) Lands for installing approach 

lighting systems are required as part of 
a project if the installing of the compo-
nents of the system on the airport is in 
an approved FAA budget, unless the 
sponsor has already acquired the land 
necessary for the system or is other-
wise undertaking to acquire that land. 
If the sponsor is otherwise undertaking 
to acquire the land, the grant agree-
ment for the project must obligate the 
sponsor to complete the acquisition 
within a time limit prescribed by the 
Administrator. The Administrator im-
mediately notifies a sponsor when a 
budget is approved providing for in-
stalling an approach lighting system at 
the airport concerned.
