FAQ – Daily Flight Duty Time Limitations Augmented Flight Crew.	FAQ – Rest Requirements

In formulating this rule, the FAA found that ‘‘scientific studies suggest that long periods of time on duty infringe upon an individual’s opportunity to sleep, thus causing a ‘sleep debt’ which is also known as cumulative fatigue.’’

With the effective date of 04 Jan 2014, it is expected that cumulative flight time will account for all flight time accrued from 05 Jan 2013 and forward from that date, and that cumulative flight duty time will account for FDP time accrued from 00:00 07 Dec 2013 and forward from that date/time, Should a certificate holder implement FAR 117 earlier than 04Jan 2014, the respective lookback should be adjusted accordingly.

Q22) What are the cumulative flight time limitations for flightcrew members?

Authors Note: The current text of the regulation, differs ,117.23(b): No certificate holder may schedule and no flightcrew member may accept an assignment if the flightcrew member’s total flight time will exceed. A technical correction is anticipated.

Q24) What are the cumulative flight duty time limitations for flightcrew members?

A24) The cumulative flight duty time limitations are stipulated in 117.23(c)(1) 60 hours in 168 hours or 117.23(c)(2) 190 hours in 672 hours, the cumulative flight duty time will include any flight duty time performed for any certificate holder or part 91K Program manager during the applied periods (117.23(a) refers).

Q26) Are reserve assignments subject to the cumulative FDP limitations?

A26)  A flightcrew member assigned to Airport/Stand-by is considered to be assigned to a FDP (ref 117.3 Definitions) and is subject to cumulative FDP limitations. A flightcrew member assigned to either Long-Call or Short-Call Reserve is not considered to be assigned to FDP. Even if a Short-Call Reserve is assigned a FDP during the RAP, the time from the start of the RAP to the start of the FDP is not to be included in the calculation of the cumulative FDP time.
