How is fuel planning done for a VFR flight that involves multiple full stops?
This may not be what your CFI is looking for, but I found the changes in fuel consumption during takeoff/landing to be negligible. This is because the taxiing uses very little, the and extra fuel burn in the climb is largely compensated by the savings in the descent. So, I just look at the distance between the airports, take winds aloft, calculate ETE and make sure it's acceptable in respect to fuel reserves. Ditto for any foreseen diversions. You have to have enough fuel on board to reach your planned reserve airport if you arrive at your destination and find that it's closed (e.g. because of an accident). This may be less of a problem in North Carolina, but in New Mexico, you might need to return all the way. A 30 minute VFR reserve isn't going to cut it.
