To follow up my moderately successful flight lesson yesterday, I made myself do a ficticious weight and balance sheet today, using only my notes and my POH, no "calling a friend". And... I did it! I made the pilot and co-pilot 205 lbs each and threw in a bit of luggage just for fun, and did the math.
The plane could take off, however, with just under an hour's worth of fuel, it wouldn't get far. So, two "robust" pilots could fly a couple of circuits, and that's about it. Ha!
