OK, at the risk of adding fuel to a fire here is my input.
Firstly, I agree, long haul flyers do have a tendency to overnight and leave the controls, but if you do that on PP you do so at your own risk, too many variables can occur that result in crashes and or penalties. Also you would not leave your cockpit for that long if you were on VATSIM or IVAO would you? Why should it be that someone who spends 7 hours flying across the Atlantic setting up the flight with correct procedures observing NATS and monitoring all situations should get the same score as a Pilot who flies 20 minutes from Zurich to Geneva and doesn't even make it to transition altitude let alone FL180? In my opinion, this is a no brainer, of course, the longer you fly and the more hours you invest, the better your score should be! There are many ways of cheating the system if you so desire but flying only short 20 minute flights on the current system offers too much of a benefit. It's horses for courses guys, at the moment, there is far too much of an advantage to flying Short flights on PP, this has to be addressed for those who prefer medium and long haul this does not make it advantageous to fly long haul, it evens the score up, you spend 7 hours long haul you get a fac that represents 7 hours of work. You fly 7 one hour flights you get the same or even better score as there is a division by total number of flights as well.
Remember we force no one to fly on PP, if you feel the system is unfair or you don't like the suspension then you will not utilise PP. Currently on average, less than 25% of EHM flights are done on PP. This says to me that only 25% of our pilots like the current system, this is not enough for the scope that this system offers. If this figure does not improve after changing the FAC system then we need to look at other areas or go back to the drawing board, if it does then we have achieved our goal. I guess what I am saying here, is vote with your flights, if you like it, then use it! If not we will continue to try to develop a system that you enjoy using! Please don't immediately criticise an idea before seeing it in operation. We are a dynamic airline and we will adapt to what our pilots want and the way I see it, PP is not being fully utilised so we need to adapt and develop it further.
Thanks and good luck!
