and Operating Requirements 
for Large and Transport Cat-
egory Aircraft

: Docket No. 18334, 54 FR 34318, Aug. 

18, 1989, unless otherwise noted. 

§ 91.601

Applicability. 

This subpart applies to operation of 

large and transport category U.S.-reg-
istered civil aircraft. 

§ 91.603

Aural speed warning device. 

No person may operate a transport 

category airplane in air commerce un-
less that airplane is equipped with an 
aural speed warning device that com-
plies with § 25.1303(c)(1). 

§ 91.605

Transport category civil air-

plane weight limitations. 

(a) No person may take off any trans-

port category airplane (other than a 
turbine-engine-powered airplane cer-
tificated after September 30, 1958) un-
less— 

(1) The takeoff weight does not ex-

ceed the authorized maximum takeoff 
weight for the elevation of the airport 
of takeoff; 

(2) The elevation of the airport of 

takeoff is within the altitude range for 
which maximum takeoff weights have 
been determined; 

(3) Normal consumption of fuel and 

oil in flight to the airport of intended 
landing will leave a weight on arrival 
not in excess of the authorized max-
imum landing weight for the elevation 
of that airport; and 

(4) The elevations of the airport of in-

tended landing and of all specified al-
ternate airports are within the altitude 
range for which the maximum landing 
weights have been determined. 

(b) No person may operate a turbine- 

engine-powered transport category air-
plane certificated after September 30, 
1958, contrary to the Airplane Flight 
Manual, or take off that airplane un-
less— 

(1) The takeoff weight does not ex-

ceed the takeoff weight specified in the 
Airplane Flight Manual for the ele-
vation of the airport and for the ambi-
ent temperature existing at the time of 
takeoff; 

(2) Normal consumption of fuel and 

oil in flight to the airport of intended 
landing and to the alternate airports 
will leave a weight on arrival not in ex-
cess of the landing weight specified in 
the Airplane Flight Manual for the ele-
vation of each of the airports involved 
and for the ambient temperatures ex-
pected at the time of landing; 

(3) The takeoff weight does not ex-

ceed the weight shown in the Airplane 
Flight Manual to correspond with the 
minimum distances required for take-
off, considering the elevation of the 
airport, the runway to be used, the ef-
fective runway gradient, the ambient 
temperature and wind component at 
the time of takeoff, and, if operating 
limitations exist for the minimum dis-
tances required for takeoff from wet 
runways, the runway surface condition 
(dry or wet). Wet runway distances as-
sociated with grooved or porous fric-
tion course runways, if provided in the 
Airplane Flight Manual, may be used 
only for runways that are grooved or 
treated with a porous friction course 
(PFC) overlay, and that the operator 
determines are designed, constructed, 
and maintained in a manner acceptable 
to the Administrator. 

(4) Where the takeoff distance in-

cludes a clearway, the clearway dis-
tance is not greater than one-half of— 

(i) The takeoff run, in the case of air-

planes certificated after September 30, 
1958, and before August 30, 1959; or 

(ii) The runway length, in the case of 

airplanes certificated after August 29, 
1959. 

(c) No person may take off a turbine- 

engine-powered transport category air-
plane certificated after August 29, 1959, 
unless, in addition to the requirements 
of paragraph (b) of this section— 

(1) The accelerate-stop distance is no 

greater than the length of the runway
