If you have to ask, you can't afford it. But seriously:
1 TFP for anything less than 243 SM. (yes, STATUTE miles, also straight line distance, not distance actually flown)
0.1 TFP for every 40 SM over that.
OR if it is more:
1 TFP/50 minutes - 0.1TFP, with an additional 0.02 TFP for every minute of actual overblock, provided it is more than 5 minutes.
I mean, why use block when you have TFP?
