§ 117.25 Rest period.
(a) No certificate holder may assign
and no flightcrew member may accept
assignment to any reserve or duty with
the certificate holder during any re-
quired rest period.
(b) Before beginning any reserve or
flight duty period a flightcrew member
must be given at least 30 consecutive
hours free from all duty within the
past 168 consecutive hour period.
(c) If a flightcrew member operating
in a new theater has received 36 con-
secutive hours of rest, that flightcrew
member is acclimated and the rest pe-
riod meets the requirements of para-
graph (b) of this section.
(d) A flightcrew member must be
given a minimum of 56 consecutive
hours rest upon return to home base if
the flightcrew member: (1) Travels
more than 60
°
longitude during a flight
duty period or a series of flight duty
period, and (2) is away from home base
for more than 168 consecutive hours
during this travel. The 56 hours of rest
specified in this section must encom-
pass three physiological nights’ rest
based on local time.
(e) No certificate holder may sched-
ule and no flightcrew member may ac-
cept an assignment for any reserve or
flight duty period unless the flightcrew
member is given a rest period of at
least 10 consecutive hours immediately
before beginning the reserve or flight
duty period measured from the time
the flightcrew member is released from
duty. The 10 hour rest period must pro-
vide the flightcrew member with a
minimum of 8 uninterrupted hours of
sleep opportunity.
(f) If a flightcrew member determines
that a rest period under paragraph (e)
of this section will not provide eight
uninterrupted hours of sleep oppor-
tunity, the flightcrew member must
notify the certificate holder. The
flightcrew member cannot report for
the assigned flight duty period until he
or she receives a rest period specified
in paragraph (e) of this section.
(g) If a flightcrew member engaged in
deadhead transportation exceeds the
applicable flight duty period in Table B
of this part, the flightcrew member
must be given a rest period equal to
the length of the deadhead transpor-
tation but not less than the required
rest in paragraph (e) of this section be-
fore beginning a flight duty period.

§ 117.27 Consecutive nighttime oper-
ations.
A certificate holder may schedule
and a flightcrew member may accept
up to five consecutive flight duty peri-
ods that infringe on the window of cir-
cadian low if the certificate holder pro-
vides the flightcrew member with an
opportunity to rest in a suitable ac-
commodation during each of the con-
secutive nighttime flight duty periods.
The rest opportunity must be at least 2
hours, measured from the time that
the flightcrew member reaches the
suitable accommodation, and must
comply with the conditions specified in
§ 117.15(a), (c), (d), and (e). Otherwise,
no certificate holder may schedule and
no flightcrew member may accept
more than three consecutive flight
duty periods that infringe on the win-
dow of circadian low. For purposes of
this section, any split duty rest that is
provided in accordance with § 117.15
counts as part of a flight duty period.
§ 117.29 Emergency and government
sponsored operations.
(a) This section applies to operations
conducted pursuant to contracts with
the U.S. Government and operations
conducted pursuant to a deviation
under § 119.57 of this chapter that can-
not otherwise be conducted under this
part because of circumstances that
could prevent flightcrew members from
being relieved by another crew or safe-
ly provided with the rest required
under § 117.25 at the end of the applica-
ble flight duty period.
