Hi Peter,

Although the Propjet obviously burns = more fuel than a piston, your estimates are a bit high. I fully agree = that I would prefer more than 125 gallons.

My Propjet does burn 50+ gph on takeoff and at low altitude. = However at 10-15 minutes to climb to cruise altitude with fuel burn at = FL220-260 being 29-33 gph, range is somewhat more than you would expect. = On descent near flight idle fuel burn can get down into the low = 20's.

On multiple flights I have estimated = that I have right around 4:30 of flight time until dry starting with = full fuel ( though I generally use my belly tank as my full hour of = reserves and never get close to dry).  I have 146 usable gallons. = Thus with 125 gallons one would estimate approximately 3 hours flight = time plus legal Ifr reserves.
