Assuming that your flight will consist of 40 minutes maneuvering, 20 minutes from the airport to the practice area, another 20 minutes back, and 20 minutes for start up, run up and taxi, plus 30 minutes VFR minimum fuel reserve, you're looking at 130 minutes or 2 hours 10 minutes total 6 gph is a little over 12, make it 13 gallons total. Remember however to visually check the fuel level in the tanks during your preflight - cross check with the fuel guage, and note the time you start your engine, so that you can calculate how much fuel has been consumed and how much is left based on the fuel flow from the POH. Don't have the tanks topped off after the previous student ties the airplane down.
Your rate of climb, particularly on hot and humid days at or near gross weight, may be surprisingly low.Also, you can reduce gross weight by flying with less than full tanks. Pipers Cherokee (and 152s) are not made for guys in the plus 250 range (195 is not that big!)I would just talk to the training unit and work out the math!Have fun!Mike Hudsonīe sure to calculate density altitude and reference the 152's performance chart in the POH before you fly.
Just as an example, when we practiced spins, we had to calculate fuel down to a few minutes. They should have the POHs for the plane you would likely train on, so check the weight and balance section of the manual. This would still give about 4 hours of endurance, so it was not a problem. If you and your instructor, plus fuel are less that or equal to the maximum gross weight, then that is not a problem, but check the weight and balance to make sure you don't exceed the aircraft limits.If you have to go on less than full fuel, then it can be a problem, but in the pipers I trained on we would go on 36 out of 50 gallons for a normal training session. As a fairly big guy myself, this is always a concern! It is somewhat aircraft dependent as the gross empty weight of each aircraft is different (radios and other equipment added on can add up to a lot!).
