§ 121.91 Applicability.
This subpart prescribes rules for ob-
taining approval of routes by certifi-
cate holders conducting domestic or
flag operations.
[Doc. No. 28154, 61 FR 2610, Jan. 26, 1996]
§ 121.93 Route requirements: General.
(a) Each certificate holder con-
ducting domestic or flag operations
seeking a route approval must show—
(1) That it is able to conduct satisfac-
torily scheduled operations between
each regular, provisional, and refueling
airport over that route or route seg-
ment; and
(2) That the facilities and services re-
quired by §§ 121.97 through 121.107 are
available and adequate for the proposed
operation.
The Administrator approves a route
outside of controlled airspace if he de-
termines that traffic density is such
that an adequate level of safety can be
assured.
(b) Paragraph (a) of this section does
not require actual flight over a route
or route segment if the certificate
holder shows that the flight is not es-
sential to safety, considering the avail-
ability and adequacy of airports, light-
ing, maintenance, communication,
navigation, fueling, ground, and air-
plane radio facilities, and the ability of
the personnel to be used in the pro-
posed operation.
[Doc. No. 6258, 29 FR 19194, Dec. 31, 1964, as
amended by Amdt. 121–3, 30 FR 3638, Mar. 19,
1965; Amdt. 121–253, 61 FR 2610, Jan. 26, 1996]
§ 121.95 Route width.
(a) Approved routes and route seg-
ments over U.S. Federal airways or for-
eign airways (and advisory routes in
the case of certificate holders con-
ducting flag operations) have a width
equal to the designated width of those
airways or routes. Whenever the Ad-
ministrator finds it necessary to deter-
mine the width of other approved
routes, he considers the following:
(1) Terrain clearance.
(2) Minimum en route altitudes.
(3) Ground and airborne navigation
aids.
(4) Air traffic density.
(5) ATC procedures.
(b) Any route widths of other ap-
proved routes determined by the Ad-
ministrator are specified in the certifi-
cate holder’s operations specifications.
[Doc. No. 6258, 29 FR 19194, Dec. 31, 1964, as
amended by Amdt. 121–253, 61 FR 2610, Jan.
26, 1996]
§ 121.97 Airports: Required data.
(a) Each certificate holder con-
ducting domestic or flag operations
must show that each route it submits
for approval has enough airports that
are properly equipped and adequate for
the proposed operation, considering
such items as size, surface, obstruc-
tions, facilities, public protection,
lighting, navigational and communica-
tions aids, and ATC.
(b) Each certificate holder con-
ducting domestic or flag operations
must show that it has an approved sys-
tem for obtaining, maintaining, and
distributing to appropriate personnel
current aeronautical data for each air-
port it uses to ensure a safe operation
at that airport. The aeronautical data
must include the following:
(1)
Airports.
(i)
Facilities.
(ii) Public protection. After February
15, 2008, for ETOPS beyond 180 minutes
or operations in the North Polar area
and South Polar area, this includes fa-
cilities at each airport or in the imme-
diate area sufficient to protect the pas-
sengers from the elements and to see to
their welfare.
(iii)
Navigational and communica-
tions aids.
(iv)
Construction affecting takeoff,
landing, or ground operations.
(v)
Air traffic facilities.
(2)
Runways, clearways and
stopways.
(i)
Dimensions.
(ii)
Surface.
(iii)
Marking and lighting systems.
(iv)
Elevation and gradient.
