§ 25.1581

General.

(a)

Furnishing information. An Air-

plane Flight Manual must be furnished
with each airplane, and it must contain
the following:

(1) Information required by §§ 25.1583

through 25.1587.

(2) Other information that is nec-

essary for safe operation because of de-
sign, operating, or handling character-
istics.

(3) Any limitation, procedure, or

other information established as a con-
dition of compliance with the applica-
ble noise standards of part 36 of this
chapter.

(b)

Approved information. Each part of

the manual listed in §§ 25.1583 through
25.1587, that is appropriate to the air-
plane, must be furnished, verified, and
approved, and must be segregated,
identified, and clearly distinguished
from each unapproved part of that
manual.

must include a table of contents if the
complexity of the manual indicates a
need for it.

§ 25.1583

Operating limitations.

(a)

Airspeed limitations. The following

airspeed limitations and any other air-
speed limitations necessary for safe op-
eration must be furnished:

(1) The maximum operating limit

speed

and a statement that

this speed limit may not be delib-
erately exceeded in any regime of
flight (climb, cruise, or descent) unless
a higher speed is authorized for flight
test or pilot training.

(2) If an airspeed limitation is based

upon compressibility effects, a state-
ment to this effect and information as
to any symptoms, the probable behav-
ior of the airplane, and the rec-
ommended recovery procedures.

(3) The maneuvering speed estab-

lished under § 25.1507 and statements,
as applicable to the particular design,
explaining that:

(i) Full application of pitch, roll, or

yaw controls should be confined to

speeds below the maneuvering speed;
and

(ii) Rapid and large alternating con-

trol inputs, especially in combination
with large changes in pitch, roll, or
yaw, and full control inputs in more
than one axis at the same time, should
be avoided as they may result in struc-
tural failures at any speed, including
below the maneuvering speed.

(4) The flap extended speed

and

the pertinent flap positions and engine
powers.

(5) The landing gear operating speed

or speeds, and a statement explaining
the speeds as defined in § 25.1515(a).

(6) The landing gear extended speed

LE,

if greater than

LO,

and a state-

ment that this is the maximum speed
at which the airplane can be safely
flown with the landing gear extended.

(b)

Powerplant limitations. The fol-

lowing information must be furnished:

(1) Limitations required by § 25.1521

and § 25.1522.

(2) Explanation of the limitations,

when appropriate.

(3) Information necessary for mark-

ing the instruments required by
§§ 25.1549 through 25.1553.

(c)

Weight and loading distribution.

The weight and center of gravity limi-
tations established under § 25.1519 must
be furnished in the Airplane Flight
Manual. All of the following informa-
tion, including the weight distribution
limitations established under § 25.1519,
must be presented either in the Air-
plane Flight Manual or in a separate
weight and balance control and loading
document that is incorporated by ref-
erence in the Airplane Flight Manual:

(1) The condition of the airplane and

the items included in the empty weight
as defined in accordance with § 25.29.

(2) Loading instructions necessary to

ensure loading of the airplane within
the weight and center of gravity limits,
and to maintain the loading within
these limits in flight.

(3) If certification for more than one

center of gravity range is requested,
the appropriate limitations, with re-
gard to weight and loading procedures,
for each separate center of gravity
range.
