Federal Register/Vol. 74, No. 71/Wednesday, April 15, 2009/Rules and Regulations

(d) If certification for instrument flight
rules or flight in icing conditions is
requested, each airspeed system must
have a heated pitot tube or an
equivalent means of preventing
malfunction due to icing.
(e) In addition, the airspeed indicating
system must be calibrated to determine
the system error during the accelerate/
takeoff ground run. The ground run
calibration must be obtained between
0.8 of the minimum value of Vi, and 1.2
times the maximum value of V1,
considering the approved ranges of
altitude and weight. The ground run
calibration must be determined
assuming an engine failure at the
minimum value of V1.
(f) Where duplicate airspeed
indicators are required, their respective
pitot tubes must be far enough apart to
avoid damage to both tubes in a
collision with a bird.
22. SC 23.1505 Airspeed Limitations
Instead of compliance with  23.1505,
the following apply:
The maximum operating limit speed
(VMo/MMo-airspeed or Mach number,
whichever is critical at a particular
altitude) is a speed that may not be
deliberately exceeded in any regime of
flight (climb, cruise, or descent), unless
a higher speed is authorized for flight
test or pilot training operations. VMO/
MMO must be established so that it is not
greater than the design cruising speed
Vc/Mc and so that it is sufficiently
below VD/MD or VDF/MDF, to make it
highly improbable that the latter speeds
will be inadvertently exceeded in
operations. The speed margin between
VMO/MMO and VD/MD or VDF/MDF may
not be less than that determined under
 23.335(b) or found necessary in the
flight test conducted under SC 23.253.
23. SC 23.1583 Operating Limitations
Instead of compliance with  23.1583,
the following apply:
The Airplane Flight Manual must
contain operating limitations
determined under this part 23,
including the following-
(a) Airspeed limitations. The
following information must be
furnished:
(1) Information necessary for the
marking of the airspeed limits on the
indicator as required in  23.1545, and
the significance of each of those limits
and of the color-coding used on the
indicator.
(2) The speeds VMC, Vo, VLE, and VLO,
if established, and their significance.
(3) In addition-
(i) The maximum operating limit
speed, VMo/MM and a statement that

this speed must not be deliberately

exceeded in any regime of flight (climb,
cruise or descent) unless a higher speed
is authorized for flight test or pilot
training;
(ii) If an airspeed limitation is based
upon compressibility effects, a
statement to this effect and information
as to any symptoms, the probable
behavior of the airplane, and the
recommended recovery procedures; and
(iii) The airspeed limits must be
shown in terms of VMO/MMo.
(b) Powerplant limitations. The
following information must be
furnished:
(1) Limitations required by  23.1521.
(2) Explanation of the limitations,
when appropriate.
(3) Information necessary for marking
the instruments required by  23.1549
through  23.1553.
(c) Weight. The airplane flight manual
must include-
(1) The maximum weight; and
(2) The maximum landing weight, if
the design landing weight selected by
the applicant is less than the maximum
weight.
(3) [Reserved]
(4) The maximum takeoff weight for
each airport altitude and ambient
temperature within the range selected
by the applicant at which-
(i) The airplane complies with the
climb requirements of SC 23.63(d)(1);
and
(ii) The accelerate-stop distance
determined under SC 23.55 is equal to
the available runway length plus the
length of any stopway, if utilized; and
either:
(iii) The takeoff distance determined
under SC 23.59(a) is equal to the
available runway length; or
(iv) At the option of the applicant, the
takeoff distance determined under SC
23.59(a) is equal to the available runway
length plus the length of any clearway
and the takeoff run determined under
SC 23.59(b) is equal to the available
runway length.
(5) The maximum landing weight for
each airport altitude within the range
selected by the applicant at which-
(i) The airplane complies with the
climb requirements of SC 23.63(d)(2) for
ambient temperatures within the range
selected by the applicant; and
(ii) The landing distance determined
under  23.75 for standard temperatures
is equal to the available runway length.
(6) The maximum zero wing fuel
weight, where relevant, as established in
accordance with  23.343.
(d) Center ofgravity. The established
center of gravity limits.
(e) Maneuvers. The following
authorized maneuvers, appropriate
airspeed limitations, and unauthorized

maneuvers, as prescribed in this section.

(1) [Reserved]
(2) [Reserved]
(3) [Reserved]
(4) [Reserved]
(5) Maneuvers are limited to any
maneuver incident to normal flying,
stalls, (except whip stalls) and steep
turns in which the angle of bank is not
more than 60 degrees.
(f) Maneuver load factor. The positive
limit load factors in g's.
(g) Minimum flight crew. The number
and functions of the minimum flight
crew determined under  23.1523.
(h) Kinds of operation. A list of the
kinds of operation to which the airplane
is limited or from which it is prohibited
under  23.1525, and also a list of
installed equipment that affects any
operating limitation and identification
as to the equipment's required
operational status for the kinds of
operation for which approval has been
given.
(i) Maximum operating altitude. The
maximum altitude established under
 23.1527.
(j) Maximum passenger seating
configuration. The maximum passenger-
seating configuration.
(k) Allowable lateral fuel loading. The
maximum allowable lateral fuel loading
differential, if less than the maximum
possible.
(1) Baggage and cargo loading. The
following information for each baggage
and cargo compartment or zone-
(1) The maximum allowable load; and
(2) The maximum intensity of
loading.
(m) Systems. Any limitations on the
