The Quick Answer
Adds pairings with a specific number of duty periods.
Duty Period - The time between reporting for duty and the end of the debrief period. A duty period may include flight segment(s) and/or deadhead segment(s).
This does not reflect the number of calendar days a pairing contains. Therefore, a 3-day pairing with an extended layover and 2-duty periods could be added to the pool.
Caution
DO NOT bid Prefer Pairing Length 1 with this property.
Strategy
Pro Tip: This property may be used in conjunction with the Prefer Pairing Length property to further specify the types of pairings a pilot prefers. Bidding these properties together will allow a pilot to avoid pairings containing a long layover.
