14 CFR Ch. I (1–1–24 Edition) 

§ 135.399 

paragraph, §§ 135.385 and 135.387 are ap-
plicable to all commuter category air-
planes notwithstanding their stated ap-
plicability to turbine-engine-powered 
large transport category airplanes. 

(d) In determining maximum 

weights, minimum distances and flight 
paths under paragraphs (a) through (c) 
of this section, correction must be 
made for the runway to be used, the 
elevation of the airport, the effective 
runway gradient, and ambient tem-
perature, and wind component at the 
time of takeoff. 

(e) For the purposes of this section, 

the assumption is that the airplane is 
not banked before reaching a height of 
50 feet as shown by the net takeoff 
flight path data in the Airplane Flight 
Manual and thereafter the maximum 
bank is not more than 15 degrees.

§ 135.399 Small nontransport category 

airplane performance operating 
limitations. 

(a) No person may operate a recipro-

cating engine or turbopropeller-pow-
ered small airplane that is certificated 
under § 135.169(b) (2), (3), (4), (5), or (6) 
unless that person complies with the 
takeoff weight limitations in the ap-
proved Airplane Flight Manual or 
equivalent for operations under this 
part, and, if the airplane is certificated 
under § 135.169(b) (4) or (5) with the 
landing weight limitations in the Ap-
proved Airplane Flight Manual or 
equivalent for operations under this 
part. 

(b) No person may operate an air-

plane that is certificated under 
§ 135.169(b)(6) unless that person com-
plies with the landing limitations pre-
scribed in §§ 135.385 and 135.387 of this 
part. For purposes of this paragraph, 
§§ 135.385 and 135.387 are applicable to 
reciprocating and turbopropeller-pow-
ered small airplanes notwithstanding 
their stated applicability to turbine en-
gine powered large transport category 
airplanes.
