Per FAR 117 you need 8 hours of sllep opportunity. For me that is a minimum of 10 hours from checkin to lobby. When you add the 1/2 local transportation each way that means my minimum rest is 11 hours. If you need more than 10 hours in the hotel to get the FAR 117 sleep opportunity then tell Scheduling what you need, then your minimum rest is 1 hour added to that.So if you need 11 hours in the hotel then your minimum rest is 12 hours. In no case should any 121 Pilot accept 10 hours rest as giving them 8 hours of sleep opportunity, and per FAR 117 only the pilot can determine what rst they need in order to get 8 hours of sleep opportunuty.
