§ 121.465 

as an aircraft dispatcher for a par-
ticular type airplane unless that per-
son has, with respect to that airplane, 
satisfactorily completed differences 
training, if applicable. 

(c) No certificate holder conducting 

domestic or flag operations may use 
any person, nor may any person serve, 
as an aircraft dispatcher unless within 
the preceding 12 calendar months the 
aircraft dispatcher has satisfactorily 
completed operating familiarization 
consisting of at least 5 hours observing 
operations under this part, in one of 
the types of airplanes in each group to 
be dispatched. This observation shall 
be made from the flight deck or, for 
airplanes without an observer seat on 
the flight deck, from a forward pas-
senger seat with headset or speaker. 
The requirement of paragraph (a) of 
this section may be reduced to a min-
imum of 2

hours by the substitution 

of one additional takeoff and landing 
for an hour of flight. The requirement 
of this paragraph may be satisfied by 
observation of 5 hours of simulator 
training for each airplane group in one 
of the simulators approved under 
§ 121.407 for the group. However, if the 
requirement of paragraph (a) is met by 
the use of a simulator, no reduction in 
hours is permitted. 

(d) No certificate holder conducting 

domestic or flag operations may use 
any person, nor may any person serve 
as an aircraft dispatcher to dispatch 
airplanes in operations under this part 
unless the certificate holder has deter-
mined that he is familiar with all es-
sential operating procedures for that 
segment of the operation over which he 
exercises dispatch jurisdiction. How-
ever, a dispatcher who is qualified to 
dispatch airplanes through one seg-
ment of an operation may dispatch air-
planes through other segments of the 
operation after coordinating with dis-
patchers who are qualified to dispatch 
airplanes through those other seg-
ments. 

(e) For the purposes of this section, 

the airplane groups, terms, and defini-
tions in § 121.400 apply.

§ 121.465 Aircraft dispatcher duty time 

limitations: Domestic and flag oper-

ations. 

(a) Each certificate holder con-

ducting domestic or flag operations 
shall establish the daily duty period for 
a dispatcher so that it begins at a time 
that allows him or her to become thor-
oughly familiar with existing and an-
ticipated weather conditions along the 
route before he or she dispatches any 
airplane. He or she shall remain on 
duty until each airplane dispatched by 
him or her has completed its flight, or 
has gone beyond his or her jurisdiction, 
or until he or she is relieved by another 
qualified dispatcher. 

(b) Except in cases where cir-

cumstances or emergency conditions 
beyond the control of the certificate 
holder require otherwise— 

(1) No certificate holder conducting 

domestic or flag operations may sched-
ule a dispatcher for more than 10 con-
secutive hours of duty; 

(2) If a dispatcher is scheduled for 

more than 10 hours of duty in 24 con-
secutive hours, the certificate holder 
shall provide him or her a rest period 
of at least eight hours at or before the 
end of 10 hours of duty. 

(3) Each dispatcher must be relieved 

of all duty with the certificate holder 
for at least 24 consecutive hours during 
any seven consecutive days or the 
equivalent thereof within any calendar 
month. 

(c) Notwithstanding paragraphs (a) 

and (b) of this section, a certificate 
holder conducting flag operations may, 
if authorized by the Administrator, 
schedule an aircraft dispatcher at a 
duty station outside of the 48 contig-
uous States and the District of Colum-
bia, for more than 10 consecutive hours 
of duty in a 24-hour period if that air-
craft dispatcher is relieved of all duty 
with the certificate holder for at least 
eight hours during each 24-hour period.
