Obstacles.
(i)
Those affecting takeoff and land-
ing performance computations in ac-
cordance with Subpart I of this part.
(ii)
Controlling obstacles.
(5)
Instrument flight procedures.
(i)
Departure procedure.

Missed approach procedure.
(6)
Special information.
(i)
Runway visual range measure-
ment equipment.
(ii)
Prevailing winds under low visi-
bility conditions.
(c) If the responsible Flight Stand-
ards office charged with the overall in-
spection of the certificate holder’s op-
erations finds that revisions are nec-
essary for the continued adequacy of
the certificate holder’s system for col-
lection, dissemination, and usage of
aeronautical data that has been grant-
ed approval, the certificate holder
shall, after notification by the respon-
sible Flight Standards office, make
those revisions in the system. Within
30 days after the certificate holder re-
ceives such notice, the certificate hold-
er may file a petition to reconsider the
notice with the Executive Director,
Flight Standards Service. This filing of
a petition to reconsider stays the no-
tice pending a decision by the Execu-
tive Director, Flight Standards Serv-
ice. However, if the responsible Flight
Standards office finds that there is an
emergency that requires immediate ac-
tion in the interest of safety in air
transportation, the Executive Director,
Flight Standards Service may, upon
statement of the reasons, require a
change effective without stay.

§ 121.99 Communications facilities—
domestic and flag operations.
(a) Each certificate holder con-
ducting domestic or flag operations
must show that a two-way communica-
tion system, or other means of commu-
nication approved by the responsible
Flight Standards office, is available
over the entire route. The communica-
tions may be direct links or via an ap-
proved communication link that will
provide reliable and rapid communica-
tions under normal operating condi-
tions between each airplane and the ap-
propriate dispatch office, and between
each airplane and the appropriate air
traffic control unit.
(b) Except in an emergency, for all
flag and domestic kinds of operations,
the communications systems between
each airplane and the dispatch office
must be independent of any system op-
erated by the United States.
(c) Each certificate holder con-
ducting flag operations must provide
voice communications for ETOPS
where voice communication facilities
are available. In determining whether
facilities are available, the certificate
holder must consider potential routes
and altitudes needed for diversion to
ETOPS Alternate Airports. Where fa-
cilities are not available or are of such
poor quality that voice communication
is not possible, another communication
system must be substituted.
(d) Except as provided in paragraph
(e) of this section, after February 15,
2008 for ETOPS beyond 180 minutes,
each certificate holder conducting flag
operations must have a second commu-
nication system in addition to that re-
quired by paragraph (c) of this section.
That system must be able to provide
immediate satellite-based voice com-
munications of landline-telephone fi-
delity. The system must be able to
communicate between the flight crew
and air traffic services, and the flight
crew and the certificate holder. In de-
termining whether such communica-
tions are available, the certificate
holder must consider potential routes
and altitudes needed for diversion to
ETOPS Alternate Airports. Where im-
mediate, satellite-based voice commu-
nications are not available, or are of
such poor quality that voice commu-
nication is not possible, another com-
munication system must be sub-
stituted.
(e) Operators of two-engine turbine-
powered airplanes with 207 minute
ETOPS approval in the North Pacific
Area of Operation must comply with
86
14 CFR Ch. I (1–1–24 Edition)
§ 121.101
the requirements of paragraph (d) of
this section as of February 15, 2007.

§ 121.101 Weather reporting facilities.
(a) Each certificate holder con-
ducting domestic or flag operations
must show that enough weather report-
ing services are available along each
route to ensure weather reports and
forecasts necessary for the operation.
(b) Except as provided in paragraph
(d) of this section, no certificate holder
conducting domestic or flag operations
may use any weather report to control
flight unless—
(1) For operations within the 48 con-
tiguous States and the District of Co-
lumbia, it was prepared by the U.S. Na-
tional Weather Service or a source ap-
proved by the U.S. National Weather
Service; or
(2) For operations conducted outside
the 48 contiguous States and the Dis-
trict of Columbia, it was prepared by a
source approved by the Administrator.
(c) Each certificate holder con-
ducting domestic or flag operations
that uses forecasts to control flight
movements shall use forecasts prepared
from weather reports specified in para-
graph (b) of this section and from any
source approved under its system
adopted pursuant to paragraph (d) of
this section.
(d) Each certificate holder con-
ducting domestic or flag operations
shall adopt and put into use an ap-
proved system for obtaining forecasts
and reports of adverse weather phe-
nomena, such as clear air turbulence,
thunderstorms, and low altitude wind
shear, that may affect safety of flight
on each route to be flown and at each
airport to be used.

§ 121.103 En route navigation facili-
ties.
(a) Except as provided in paragraph
(b) of this section, each certificate
holder conducting domestic or flag op-
erations must show, for each proposed
route (including to any regular, provi-
sional, refueling or alternate airports),
that suitable navigation aids are avail-
able to navigate the airplane along the
route within the degree of accuracy re-
quired for ATC. Navigation aids re-
quired for approval of routes outside of
controlled airspace are listed in the
certificate holder’s operations speci-
fications except for those aids required
for routes to alternate airports.
(b) Navigation aids are not required
for any of the following operations—
(1) Day VFR operations that the cer-
tificate holder shows can be conducted
safely by pilotage because of the char-
acteristics of the terrain;
(2) Night VFR operations on routes
that the certificate holder shows have
reliably lighted landmarks adequate
for safe operation; and
(3) Other operations approved by the
responsible Flight Standards office.

§ 121.105 Servicing and maintenance
facilities.
Each certificate holder conducting
domestic or flag operations must show
that competent personnel and adequate
facilities and equipment (including
spare parts, supplies, and materials)
are available at such points along the
certificate holder’s route as are nec-
essary for the proper servicing, mainte-
nance, and preventive maintenance of
airplanes and auxiliary equipment.

§ 121.106 ETOPS Alternate Airport:
Rescue and fire fighting service.
(a) Except as provided in paragraph
(b) of this section, the following rescue
and fire fighting service (RFFS) must
be available at each airport listed as an
ETOPS Alternate Airport in a dispatch
or flight release.
(1) For ETOPS up to 180 minutes,
each designated ETOPS Alternate Air-
port must have RFFS equivalent to
that specified by ICAO as Category 4,
or higher.
(2) For ETOPS beyond 180 minutes,
each designated ETOPS Alternate Air-
port must have RFFS equivalent to
that specified by ICAO Category 4, or
