Sorry i think we jacked this thread from the OP....however... i reported the fuel differences when i got back on the ground, The CFI and i dipped the tanks there was a 20 odd liter difference (both tanks had been equally filled as per the sheet when i took off) so there was a difference,.. he also suggested i was not flying in balance... i was slightly offended being an ex glider pilot 'n' all.
However i have gone and looked at the photo's of the trip... (my dad got very snap happy) and...yep the G1000 suite tells me what i need to know... 22 kt crosswind from....you guessed it...the left.... for most of the flight.
soo.... erm...not totally in balance then... even the GPS shows my crab...
