Section 135.385

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

(1) There is no place along the intended track that is more than 90 minutes (with all engines operating at
cruising power) from an airport that
meets Section 135.387.
(2) Its weight, according to the twoengine-inoperative, en route, net flight
path data in the Airplane Flight Manual allows the airplane to fly from the
point where the two engines are assumed to fail simultaneously to an airport that meets Section 135.387 with a net
flight path (considering the ambient
temperatures anticipated along the
track) having a positive slope at an altitude of at least 1,000 feet above all
terrain and obstructions within five
statute miles on each side of the intended track, or at an altitude of 2,000
feet, whichever is higher.
For the purpose of paragraph (b)(2) of
this section, it is assumed that the two
engines fail at the most critical point
en route, that the airplane-s weight at
the point where the engines fail includes enough fuel to continue to the
airport, to arrive at an altitude of at
least 1,500 feet directly over the airport, and after that to fly for 15 minutes at cruise power or thrust, or both,
and that the consumption of fuel and
oil after engine failure is the same as
the consumption allowed for in the net
flight path data in the Airplane Flight
Manual.
(c) Aircraft certificated after August
29, 1959 (SR422B). No person may operate a turbine engine powered large
transport category airplane along an
intended route unless that person complies with either of the following:
(1) There is no place along the intended track that is more than 90 minutes (with all engines operating at
cruising power) from an airport that
meets Section 135.387.
(2) Its weight, according to the twoengine-inoperative, en route, net flight
path data in the Airplane Flight Manual, allows the airplane to fly from the
point where the two engines are assumed to fail simultaneously to an airport that meets Section 135.387, with the net
flight path (considering the ambient
temperatures anticipated along the
track) clearing vertically by at least
2,000 feet all terrain and obstructions
within five statute miles on each side

of the intended track. For the purposes
of this paragraph, it is assumed that - 
(i) The two engines fail at the most
critical point en route;
(ii) The net flight path has a positive
slope at 1,500 feet above the airport
where the landing is assumed to be
made after the engines fail;
(iii) Fuel jettisoning will be approved
if the certificate holder shows that the
crew is properly instructed, that the
training program is adequate, and that
all other precautions are taken to ensure a safe procedure;
(iv) The airplane-s weight at the
point where the two engines are assumed to fail provides enough fuel to
continue to the airport, to arrive at an
altitude of at least 1,500 feet directly
over the airport, and after that to fly
for 15 minutes at cruise power or
thrust, or both; and
(v) The consumption of fuel and oil
after the engines fail is the same as the
consumption that is allowed for in the
net flight path data in the Airplane
Flight Manual.
Section 135.385 Large transport category airplanes: Turbine engine powered:
Landing limitations: Destination
airports.
(a) No person operating a turbine engine powered large transport category
airplane may take off that airplane at
a weight that (allowing for normal consumption of fuel and oil in flight to the
destination or alternate airport) the
weight of the airplane on arrival would
exceed the landing weight in the Airplane Flight Manual for the elevation
of the destination or alternate airport
and the ambient temperature anticipated at the time of landing.
(b) Except as provided in paragraph
(c), (d), (e), or (f) of this section, no person operating a turbine engine powered
large transport category airplane may
take off that airplane unless its weight
on arrival, allowing for normal consumption of fuel and oil in flight (in
accordance with the landing distance
in the Airplane Flight Manual for the
elevation of the destination airport and
the wind conditions expected there at
the time of landing), would allow a full
stop landing at the intended destination airport within 60 percent of the effective length of each runway described
