Section 91.611

14 CFR Ch. I (1-1-19 Edition)

(iii) Operations from airports where
the runways may require a takeoff or
approach over populated areas; and
(iv) Inspection procedures for determining the operating condition of the
operative engines.
(4) No person may take off an airplane under this section if - 
(i) The initial climb is over thickly
populated areas; or
(ii) Weather conditions at the takeoff
or destination airport are less than
those required for VFR flight.
(5) Persons other than required flight
crewmembers shall not be carried during the flight.
(6) No person may use a flight crewmember for flight under this section
unless that crewmember is thoroughly
familiar with the operating procedures
for one-engine inoperative ferry flight
contained in the certificate holder-s
manual and the limitations and performance information in the Airplane
Flight Manual.
(b) Flight tests: reciprocating-enginepowered airplanes. The airplane performance of a reciprocating-enginepowered airplane with one engine inoperative must be determined by flight
test as follows:
(1) A speed not less than 1.3 VS1 must
be chosen at which the airplane may be
controlled satisfactorily in a climb
with the critical engine inoperative
(with its propeller removed or in a configuration desired by the operator and
with all other engines operating at the
maximum power determined in paragraph (b)(3) of this section.
(2) The distance required to accelerate to the speed listed in paragraph
(b)(1) of this section and to climb to 50
feet must be determined with - 
(i) The landing gear extended;
(ii) The critical engine inoperative
and its propeller removed or in a configuration desired by the operator; and
(iii) The other engines operating at
not more than maximum power established under paragraph (b)(3) of this
section.
(3) The takeoff, flight and landing
procedures, such as the approximate
trim settings, method of power application, maximum power, and speed must
be established.
(4) The performance must be determined at a maximum weight not great-

er than the weight that allows a rate of
climb of at least 400 feet per minute in
the en route configuration set forth in
Section 25.67(d) of this chapter in effect on
January 31, 1977, at an altitude of 5,000
feet.
(5) The performance must be determined using temperature accountability for the takeoff field length,
computed in accordance with Section 25.61 of
this chapter in effect on January 31,
1977.
(c) Flight tests: Turbine-engine-powered
airplanes. The airplane performance of
a turbine-engine-powered airplane with
one engine inoperative must be determined by flight tests, including at
least three takeoff tests, in accordance
with the following:
(1) Takeoff speeds VR and V2, not less
than the corresponding speeds under
which the airplane was type certificated under Section 25.107 of this chapter,
must be chosen at which the airplane
may be controlled satisfactorily with
the critical engine inoperative (with
its propeller removed or in a configuration desired by the operator, if applicable) and with all other engines operating at not more than the power selected for type certification as set
forth in Section 25.101 of this chapter.
(2) The minimum takeoff field length
must be the horizontal distance required to accelerate and climb to the
35-foot height at V2 speed (including
any additional speed increment obtained in the tests) multiplied by 115
percent and determined with - 
(i) The landing gear extended;
(ii) The critical engine inoperative
and its propeller removed or in a configuration desired by the operator (if
applicable); and
(iii) The other engine operating at
not more than the power selected for
type certification as set forth in Section 25.101
of this chapter.
(3) The takeoff, flight, and landing
procedures such as the approximate
trim setting, method of power application, maximum power, and speed must
be established. The airplane must be
satisfactorily controllable during the
entire takeoff run when operated according to these procedures.
