Introduction
What is the FNPRM?
The FAA published the FNPRM (Final Notice of Proposed Rule Making) on
04Jan2012 in the Federal Register.
The regulations establish:
Pilot - Flight / Duty Time Limitations and Rest Requirements.
When do the Airlines have to comply?
Simply put, 04Jan2014, this date is two years since the publication date.
What do the Airlines have to do to comply?
Develop scheduling policies.
Develop training programs.
Update their Operations Specification (OPSPEC).
Upgrade crewmember scheduling software, including crew planning and
crew tracking software.

Major Changes
Applicability:
• Part 121 passenger operations must apply FAR part 117 for
all operations conducted under o Domestic (subpart Q) or
o Flag (subpart R) or
o Supplemental (subpart S)
• Part 121 All cargo operations
o may still operate under FAR 121 subparts Q, R or S

Basic Definitions
Calendar day
means a 24-hour period from 0000 through 2359 using Coordinated Universal Time (UTC) or
local time (Base time).
Duty
means any task that a flightcrew member performs as required by the certificate holder,
including but not limited to flight duty period, flight duty, pre- and post-flight duties,
administrative work, training, deadhead transportation, aircraft positioning on the ground,
aircraft loading, and aircraft servicing.
Report time
means the time that the certificate holder requires a flightcrew member to report for an
assignment.
Rest period
means a continuous period determined prospectively during which the flightcrew member is
free from all restraint by the certificate holder, including freedom from present responsibility
for work should the occasion arise.
Copyright © 2012-2013 Understanding FAR 117 – A Generic Interpretation All rights reserved.
Basic Definitions
Scheduled
means to appoint, assign, or designate for a fixed time.
Sleep opportunity
means a period of time when a crewmember is provided and allowed to be in a suitable
accommodation to rest in.
Suitable accommodation
means a temperature-controlled facility with sound mitigation and the ability to control light
that provides a flightcrew member with the ability to sleep either in a bed, bunk or in a chair
that allows for flat or near flat sleeping position. Suitable accommodation only applies to ground
facilities and does not apply to aircraft onboard rest facilities.
Unforeseen operational circumstance
means an unplanned event of insufficient duration to allow for adjustments to schedules,
including unforecast weather, equipment malfunction, or air traffic delay that is not reasonably
expected.

Note:
Difference
between
Duty Time
and FDP
Flight Time between
rest periods is the sum of the
Block for all legs
contained within the
duty period.
Augmentation
The use of Augmentation is restricted under the following
conditions:
• At least one flightcrew member with a PIC type rating must be present
and alert on the flight deck at all times.
• A limitation of 3 flight segments in any FDP.
• Ninety consecutive minutes are available for in-flight rest for the pilot
performing monitoring duties during landing.
• The flightcrew member who will be landing the aircraft on the final leg
of the FDP is required to have 2 hours of uninterrupted rest in the
second half of the FDP.
Copyright © 2012-2013 Understanding FAR 117 – A Generic Interpretation All rights reserved.
Augmentation
Rest facility means a bunk or seat accommodation installed in an aircraft that
provides a flightcrew member with a sleep opportunity.
1) Class 1 rest facility means a bunk or other surface that allows for a flat
sleeping position and is located separate from both the flight deck and passenger
cabin in an area that is temperature-controlled, allows the flightcrew member to
control light, and provides isolation from noise and disturbance.
2) Class 2 rest facility means a seat in an aircraft cabin that allows for a flat or
near flat sleeping position; is separated from passengers by a minimum of a
curtain to provide darkness and some sound mitigation; and is reasonably free
from disturbance by passengers or flightcrew members.
3) Class 3 rest facility means a seat in an aircraft cabin or flight deck that reclines
at least 40 degrees and provides leg and foot support.
Copyright © 2012-2013 Understanding FAR 117 – A Generic Interpretation All rights reserved.
Augmentation
Applied Flightcrew Member Schemes
All operational flights contained within a FDP shall be evaluated to determine
the minimum applied scheme as follows:
This is consistent with current FAR interpretations, to avoid circumvention of
Flight Time / Flight Duty Time Limitations and Rest Requirements.
FDP with more than 3 legs scheduled, must apply
• 2 Pilot Schemes (Un-augmented).

Acclimatization
A crewmember is deemed to be acclimated whenever that individual has either:
• At least 36 hours continuous rest within a specific theater
or
• Has remained in a specific theater for at least 72 hours.
Otherwise the individual is NOT acclimated.

WOCL
Physiological night’s rest means 10 hours rest that
encompasses the hours of 0100 and 0700 at the crewmember’s
home base, unless the individual has acclimated to a different
theater. If the crewmember has acclimated, the rest must
encompass the hours of 0100 and 0700 at the acclimated
location.
Window of circadian low means a period of maximum
sleepiness that occurs between 0200 and 0559 during a
physiological night.

Split Duty Period
Split Duty:
•
•
Is a duty that contains a duty break.
Is only applied to un-augmented flightcrews.
Duty Break:
•
•
•
•
•
Is a span of time in which an individual is in a suitable accommodation (Hotel) for no
less than 3:00 and not more than a required rest period.
A duty break must occur between 22:00 and 05:00 (Local)
A duty break is NOT considered a rest period.
A duty break is scheduled prior to the start of the FDP.
The actual duty break given must be no less than the scheduled duty break.

during the RAP, and no further extension beyond 20:00 will be permitted if the condition is known before
takeoff. As you can see the FDP is extended beyond the combined RAP and FDP limit of 16:00.

In this example, we can see how the combined RAP and FDP limitation is now the controlling factor.
Since the Combined RAP and FDP, requires a scheduled end of the FDP by 19:00, it will only be permitted
to be extended by 2:00 until 21:00, even though the FDP assigned during the RAP would permit the
extension to 22:00.
Extension rules that are still in effect are previous extensions beyond 0:30 within the previous 168:00
without an intervening rest greater than or equal to 30:00, and Cumulative FDP limitations.
