I use a piece of A5 paper. Date at the top, plane reg and hobbs/tacho start
Then brakes off/on
field of departure/arrival
a few notes around the edge like QNH transponder etc.
Its all you need VFR. Could make a wind vector on the chart too!
As for weight and balance in a 152? you only have two seats pretty much in the area of balance(one third chord usually works) So just look at the MTOW minus the empty weight and take yours and your paessengers weight and thats it! Not a lot you can do if your pax is too light/heavy. Cant exaclty put him in the back
and before some smart R's says some 152's have a third seat, well its only for baby's, little people and Dwarfs
Please accept my appologies in advance if you are vertically challenged
