§ 135.367 

(e) Each certificate holder operating 

a small nontransport category airplane 
shall comply with § 135.399. 

(f) The performance data in the Air-

plane Flight Manual applies in deter-
mining compliance with §§ 135.365 
through 135.387. Where conditions are 
different from those on which the per-
formance data is based, compliance is 
determined by interpolation or by com-
puting the effects of change in the spe-
cific variables, if the results of the in-
terpolation or computations are sub-
stantially as accurate as the results of 
direct tests. 

(g) No person may take off a recipro-

cating engine powered large transport 
category airplane at a weight that is 
more than the allowable weight for the 
runway being used (determined under 
the runway takeoff limitations of the 
transport category operating rules of 
this subpart) after taking into account 
the temperature operating correction 
factors in section 4a.749a-T or section 
4b.117 of the Civil Air Regulations in 
effect on January 31, 1965, and in the 
applicable Airplane Flight Manual. 

(h) The Administrator may author- 

ize in the operations specifications de-
viations from this subpart if special 
circumstances make a literal observ- 
ance of a requirement unnecessary for 
safety. 

(i) The 10-mile width specified in 

§§ 135.369 through 135.373 may be re-
duced to 5 miles, for not more than 20 
miles, when operating under VFR or 
where navigation facilities furnish reli-
able and accurate identification of high 
ground and obstructions located out-
side of 5 miles, but within 10 miles, on 
each side of the intended track. 

(j) Each certificate holder operating 

a commuter category airplane shall 
comply with § 135.398.

§ 135.364 Maximum flying time outside 

the United States. 

After August 13, 2008, no certificate 

holder may operate an airplane, other 
than an all-cargo airplane with more 
than two engines, on a planned route 
that exceeds 180 minutes flying time 
(at the one-engine-inoperative cruise 
speed under standard conditions in still 

air) from an Adequate Airport outside 
the continental United States unless 
the operation is approved by the FAA 
in accordance with Appendix G of this 
part, Extended Operations (ETOPS).

§ 135.365 Large transport category air-

planes: Reciprocating engine pow-

ered: Weight limitations. 

(a) No person may take off a recipro-

cating engine powered large transport 
category airplane from an airport lo-
cated at an elevation outside of the 
range for which maximum takeoff 
weights have been determined for that 
airplane. 

(b) No person may take off a recipro-

cating engine powered large transport 
category airplane for an airport of in-
tended destination that is located at an 
elevation outside of the range for 
which maximum landing weights have 
been determined for that airplane. 

(c) No person may specify, or have 

specified, an alternate airport that is 
located at an elevation outside of the 
range for which maximum landing 
weights have been determined for the 
reciprocating engine powered large 
transport category airplane concerned. 

(d) No person may take off a recipro-

cating engine powered large transport 
category airplane at a weight more 
than the maximum authorized takeoff 
weight for the elevation of the airport. 

(e) No person may take off a recipro-

cating engine powered large transport 
category airplane if its weight on ar-
rival at the airport of destination will 
be more than the maximum authorized 
landing weight for the elevation of that 
airport, allowing for normal consump-
tion of fuel and oil en route. 

§ 135.367 Large transport category air-

planes: Reciprocating engine pow-

ered: Takeoff limitations. 

(a) No person operating a recipro-

cating engine powered large transport 
category airplane may take off that 
airplane unless it is possible— 

(1) To stop the airplane safely on the 

runway, as shown by the accelerate- 
stop distance data, at any time during 
takeoff until reaching critical-engine 
failure speed;
