Hub-Turns and FAR Part 117
May 10, 2012
There is a popular misconception that FAR Part 117 rules for Flight and Duty times will destroy week on/week off flying. That’s just not true. Let’s consider the MEM A300 June 2012 Schedule:
1) FAR 117 allows up to 5 consecutive nights as long as the crews receive 2 hours in a suitable accommodation (sleep room or recliner room.

2) That means a total hub-turn time of at least 3+30 (30 minute postflight+2 hour rest+1hour flight planning).
3) For the June 2012 MEM A300 schedule that equates to 82% of the sort facility hub-turns would meet the requirement for 5 consecutive nights.
4) The cities that did not are the likes of MEM-YYC, MEM-BUR, OAK-AFW and ORD-AFW, all of which are much higher block and some of which are only built for 3 consecutive nights now.
