§ 91.1057

Flight, duty and rest time re-

quirements: All crewmembers. 

(a) For purposes of this subpart— 

Augmented flight crew 

means at least 

three pilots. 

Calendar day 

means the period of 

elapsed time, using Coordinated Uni-
versal Time or local time that begins 
at midnight and ends 24 hours later at 
the next midnight. 

Duty period 

means the period of 

elapsed time between reporting for an 
assignment involving flight time and 
release from that assignment by the 
program manager. All time between 
these two points is part of the duty pe-
riod, even if flight time is interrupted 
by nonflight-related duties. The time is 
calculated using either Coordinated 
Universal Time or local time to reflect 
the total elapsed time. 

Extension of flight time 

means an in-

crease in the flight time because of cir-
cumstances beyond the control of the 
program manager or flight crew-
member (such as adverse weather) that 
are not known at the time of departure 
and that prevent the flightcrew from 
reaching the destination within the 
planned flight time. 

Flight attendant 

means an individual, 

other than a flight crewmember, who is 
assigned by the program manager, in 
accordance with the required minimum 
crew complement under the program 
manager’s management specifications 
or in addition to that minimum com-
plement, to duty in an aircraft during 
flight time and whose duties include 
but are not necessarily limited to 
cabin-safety-related responsibilities. 

Multi-time zone 

flight means an eas-

terly or westerly flight or multiple 
flights in one direction in the same 
duty period that results in a time zone 
difference of 5 or more hours and is 
conducted in a geographic area that is 
south of 60 degrees north latitude and 
north of 60 degrees south latitude. 

Reserve status 

means that status in 

which a flight crewmember, by ar-
rangement with the program manager: 
Holds himself or herself fit to fly to the 
extent that this is within the control 
of the flight crewmember; remains
