We have two duty day limits. One PWA and one FAR117

The PWA limit is derived from section D charts and appears on your rotation as: ACT/MAX. For example. 10:30/13

The max is PWA derived and is extended by 2 hours, no choice. So essentially just add 2 hours to that MAX number. It is there to protect us from sitting around unlimited to be deadheaded somewhere. It INCLUDES 30 min for post flight duties

The FAR117 limit appears on your rotation as: Not Ext/ext/max block. For example: 13/15/9

So you may call it quits at 13 hours report to block in FAR117. It DOES NOT INCLUDE 30 minute post flight. You are done operating the aircraft. However, the company may have you sit around longer to 15 hours, to deadhead somewhere. Both are extendable by up to 2 hours at your option. That is each individual pilot's choice.

We can do all this now.
