14 CFR Ch. I (1–1–24 Edition) 

§ 171.205 

(1) A description of the facility and 

evidence that the equipment meets the 
performance requirements of § 171.207 
and is installed in accordance with 
§ 171.209. 

(2) A proposed procedure for oper-

ating the facility. 

(3) A proposed maintenance organiza-

tion and a maintenance manual that 
meets the requirements of § 171.211. 

(4) A statement of intent to meet the 

requirement of this subpart. 

(5) A showing that the facility has an 

acceptable level of operational reli-
ability, and an acceptable standard of 
performance. Previous equivalent oper-
ational experience may be shown to 
comply with this subparagraph. 

(b) After the Federal Aviation Ad-

ministration inspects and evaluates 
the facility, it advises the owner of the 
results and of any required changes in 
the facility or the maintenance manual 
or maintenance organization. The 
owner shall then correct the defi-
ciencies, if any, and operate the facil-
ity for an in-service evaluation by the 
Federal Aviation Administration. 

§ 171.205 Minimum requirements for 

approval. 

(a) The following are the minimum 

requirements that must be met before 
the Federal Aviation Administration 
will approve an IFR procedure which 
incorporates the use of a non-Federal 
VHF marker beacon facility under this 
subpart: 

(1) The facility’s performances, as de-

termined by air and ground inspection, 
must meet the requirements of 
§ 171.207. 

(2) The installation of the equipment 

must meet the requirements of 
§ 171.209. 

(3) The owner must agree to operate 

and maintain the facility in accord-
ance with § 171.211. 

(4) The owner must agree to furnish 

periodic reports, as set forth in 
§ 171.213, and agree to allow the Federal 
Aviation Administration to inspect the 
facility and its operation whenever 
necessary. 

(5) The owner must assure the Fed-

eral Aviation Administration that he 
will not withdraw the facility from 
service without the permission of the 
Federal Aviation Administration. 

(6) The owner must bear all costs of 

meeting the requirements of this sec-
tion and of any flight or ground inspec-
tions made before the facility is com-
missioned, except that the Federal 
Aviation Administration may bear cer-
tain of these costs subject to budgetary 
limitations and policy established by 
the Administrator. 

(b) If the applicant for approval 

meets the requirements of paragraph 
(a) of this section, the Federal Aviation 
Administration commissions the facil-
ity as a prerequisite to its approval for 
use in an IFR procedure. The approval 
is withdrawn at any time the facility 
does not continue to meet those re-
quirements. 

§ 171.207 Performance requirements. 

(a) VHF Marker Beacons must meet 

the performance requirements set forth 
in the ‘‘International Standards and 
Recommended Practices, Aeronautical 
Telecommunications, Part I, para-
graphs 3.1.6 and 3.6.’’ (Annex 10 to the 
Convention on International Civil 
Aviation) except those portions that 
pertain to identification. Identification 
of a marker beacon (75 MHz) must be in 
accordance with ‘‘U.S. Standard Flight 
Inspection Manual,’’ § 219. 

(b) The facility must perform in ac-

cordance with recognized and accepted 
good electronic engineering practices 
for the desired service. The facility 
must be checked periodically during 
the in-service test evaluation period 
for calibration and stability. These 
tests and ground tests of the marker 
radiation characteristics must be con-
ducted in accordance with the mainte-
nance manual required by § 171.211(b). 

(c) It must be shown during ground 

inspection of the design features of the 
equipment that there will not be condi-
tions that will allow unsafe operations 
because of component failure or dete-
rioration. 

(d) Flight inspection to determine 

the adequacy of the facility’s oper-
ational performance and compliance 
with applicable ‘‘Standards and Rec-
ommended Practices’’ are conducted in 
accordance with the ‘‘U.S. Standard 
Flight Inspection Manual.’’ The origi-
nal test is made by the Federal Avia-
tion Administration and later tests

Federal Aviation Administration, DOT 

§ 171.211 

must be made under arrangements, sat-
isfactory to the Federal Aviation Ad-
ministration, that are made by the 
owner. 

§ 171.209 Installation requirements. 

(a) The facility must be installed ac-

cording to accepted good engineering 
practices, applicable electric and safe-
ty codes, and Federal Communications 
Commission requirements. 

(b) The facility must have a reliable 

source of suitable primary power. 

(c) Dual transmitting equipment may 

be required, if applicable, to support 
certain IFR procedures. 

(d) At facilities within or imme-

diately adjacent to controlled airspace 
and that are intended for use as instru-
ment approach aids for an airport, 
there must be ground-air communica-
tions or reliable communications (at 
least a landline telephone) from the 
airport to the nearest Federal Aviation 
Administration air traffic control or 
communication facility. Compliance 
with this paragraph need not be shown 
at airports where an adjacent Federal 
Aviation Administration facility can 
communicate with aircraft on the 
ground at the airport and during the 
entire proposed instrument approach 
procedure. In addition, at low traffic 
density airports within or immediately 
adjacent to controlled airspace, and 
where extensive delays are not a fac-
tor, the requirements of this paragraph 
may be reduced to reliable communica-
tions (at least a landline telephone) 
from the airport to the nearest Federal 
Aviation Administration air traffic 
control or communications facility, if 
an adjacent Federal Aviation Adminis-
tration facility can communicate with 
aircraft during the proposed instru-
ment approach procedure, at least 
down to the minimum en route alti-
tude for the controlled airspace area.
