Hello
I am having some struggle with the fuel planning for the Cessna 510 Mustang. I believe the calculated fuel is a bit too high.
Let’s say I do a test flight plan LIRF - LGST @FL350 (a flight I got from OnAir dispatch) with no alternate, no contingency, no reserve (just to see the pure Fuel Burn and system calculates 2’085 lb block fuel.
I found on the web the Flight Planning Guide for this airplane and according to the table, if I take the same flight data (800 NM , FL350) I have an estimation of 1’600 lb
According to manual this includes:
-Cruise Climb
-High-Speed cruise
-High-Speed descent
-ISA, zero winds enroute
-Flight time includes climb,cruise and descent
-Fuel burn includes 60 pound for taxi and takeoff
-Three Passengers @200 pound each, single pilot (I am consideing 190 ponds/passenger and single pilot)
I think there is a bit of discrepancy and I’d like to ask if is possible review this aircraft profile
