Code of Federal Regulations - Title 14

796

14 CFR Ch. I (1–1–14 Edition)

§ 91.1039

no person may take off a turbojet air-
plane when the appropriate weather re-
ports or forecasts, or any combination
of them, indicate that the runways at
the destination or alternate airport
may be wet or slippery at the esti-
mated time of arrival unless the effec-
tive runway length at the destination
airport is at least 115 percent of the
runway length required under para-
graph (b) or (c) of this section.

§ 91.1039

IFR takeoff, approach and

landing minimums.

(a) No pilot on a program aircraft op-

erating a program flight may begin an
instrument approach procedure to an
airport unless—

(1) Either that airport or the alter-

nate airport has a weather reporting
facility operated by the U.S. National
Weather Service, a source approved by
the U.S. National Weather Service, or a
source approved by the Administrator;
and

(2) The latest weather report issued

by the weather reporting facility in-
cludes a current local altimeter setting
for the destination airport. If no local
altimeter setting is available at the
destination airport, the pilot must ob-
tain the current local altimeter setting
from a source provided by the facility
designated on the approach chart for
the destination airport.

(b) For flight planning purposes, if

the destination airport does not have a
weather reporting facility described in
paragraph (a)(1) of this section, the
pilot must designate as an alternate an
airport that has a weather reporting
facility meeting that criteria.

and visibility landing minimums pre-
scribed in part 97 of this chapter or in
the program manager’s management
specifications are increased by 100 feet
and

⁄

mile respectively, but not to ex-

ceed the ceiling and visibility mini-
mums for that airport when used as an
alternate airport, for each pilot in
command of a turbine-powered aircraft
who has not served at least 100 hours as
pilot in command in that type of air-
craft.

(d) No person may take off an air-

craft under IFR from an airport where
weather conditions are at or above
takeoff minimums but are below au-

thorized IFR landing minimums unless
there is an alternate airport within one
hour’s flying time (at normal cruising
speed, in still air) of the airport of de-
parture.

(e) Each pilot making an IFR takeoff

or approach and landing at an airport
must comply with applicable instru-
ment approach procedures and take off
and landing weather minimums pre-
scribed by the authority having juris-
diction over the airport. In addition, no
pilot may, at that airport take off
when the visibility is less than 600 feet.

§ 91.1041

Aircraft proving and valida-

tion tests.

(a) No program manager may permit

the operation of an aircraft, other than
a turbojet aircraft, for which two pilots
are required by the type certification
requirements of this chapter for oper-
ations under VFR, if it has not pre-
viously proved such an aircraft in oper-
ations under this part in at least 25
hours of proving tests acceptable to the
Administrator including—

(1) Five hours of night time, if night

flights are to be authorized;

(2) Five instrument approach proce-

dures under simulated or actual condi-
tions, if IFR flights are to be author-
ized; and

(3) Entry into a representative num-

ber of en route airports as determined
by the Administrator.

(b) No program manager may permit

the operation of a turbojet airplane if
it has not previously proved a turbojet
airplane in operations under this part
in at least 25 hours of proving tests ac-
ceptable to the Administrator includ-
ing—

(1) Five hours of night time, if night

flights are to be authorized;

(2) Five instrument approach proce-

dures under simulated or actual condi-
tions, if IFR flights are to be author-
ized; and

(3) Entry into a representative num-

ber of en route airports as determined
by the Administrator.

passengers in an aircraft during prov-
ing tests, except those needed to make
the tests and those designated by the
Administrator to observe the tests.
However, pilot flight training may be
conducted during the proving tests.
