§ 135.353 

(b) Recurrent ground training for 

crewmembers must include at least the 
following: 

(1) A quiz or other review to deter-

mine the crewmember’s knowledge of 
the aircraft and crewmember position 
involved. 

(2) Instruction as necessary in the 

subjects required for initial ground 
training by this subpart, as appro-
priate, including low-altitude 
windshear training and training on op-
erating during ground icing conditions 
as prescribed in § 135.341 and described 
in § 135.345, crew resource management 
training as prescribed in § 135.330, and 
emergency training as prescribed in 
§ 135.331. 

(c) Recurrent flight training for pi-

lots must include, at least, flight train-
ing in the maneuvers or procedures in 
this subpart, except that satisfactory 
completion of the check required by 
§ 135.293 within the preceding 12 cal-
endar months may be substituted for 
recurrent flight training.

§ 135.353 [Reserved] 

Subpart I—Airplane Performance 

Operating Limitations 

§ 135.361 Applicability. 

(a) This subpart prescribes airplane 

performance operating limitations ap-
plicable to the operation of the cat-
egories of airplanes listed in § 135.363 
when operated under this part. 

(b) For the purpose of this subpart, 

effective length of the runway, 

for land-

ing means the distance from the point 
at which the obstruction clearance 
plane associated with the approach end 
of the runway intersects the centerline 
of the runway to the far end of the run-
way. 

(c) For the purpose of this subpart, 

obstruction clearance plane 

means a 

plane sloping upward from the runway 
at a slope of 1:20 to the horizontal, and 
tangent to or clearing all obstructions 
within a specified area surrounding the 
runway as shown in a profile view of 
that area. In the plan view, the center-
line of the specified area coincides with 

the centerline of the runway, beginning 
at the point where the obstruction 
clearance plane intersects the center-
line of the runway and proceeding to a 
point at least 1,500 feet from the begin-
ning point. After that the centerline 
coincides with the takeoff path over 
the ground for the runway (in the case 
of takeoffs) or with the instrument ap-
proach counterpart (for landings), or, 
where the applicable one of these paths 
has not been established, it proceeds 
consistent with turns of at least 4,000- 
foot radius until a point is reached be-
yond which the obstruction clearance 
plane clears all obstructions. This area 
extends laterally 200 feet on each side 
of the centerline at the point where the 
obstruction clearance plane intersects 
the runway and continues at this width 
to the end of the runway; then it in-
creases uniformly to 500 feet on each 
side of the centerline at a point 1,500 
feet from the intersection of the ob-
struction clearance plane with the run-
way; after that it extends laterally 500 
feet on each side of the centerline. 

§ 135.363 General. 

(a) Each certificate holder operating 

a reciprocating engine powered large 
transport category airplane shall com-
ply with §§ 135.365 through 135.377. 

(b) Each certificate holder operating 

a turbine engine powered large trans-
port category airplane shall comply 
with §§ 135.379 through 135.387, except 
that when it operates a turbopropeller- 
powered large transport category air-
plane certificated after August 29, 1959, 
but previously type certificated with 
the same number of reciprocating en-
gines, it may comply with §§ 135.365 
through 135.377. 

(c) Each certificate holder operating 

a large nontransport category airplane 
shall comply with §§ 135.389 through 
135.395 and any determination of com-
pliance must be based only on approved 
performance data. For the purpose of 
this subpart, a large nontrans- port 
category airplane is an airplane that 
was type certificated before July 1, 
1942. 

(d) Each certificate holder operating 

a small transport category airplane 
shall comply with § 135.397.
