pd2
I use my excel w&b for every flight as a timesaver. I made it myself using the real figures from the Schweizer I use it for.
Of course do I check its accuracy by handcalculating it regularly. I am required by the regulations governing Aerial Work, to check my spreadsheet at regular intervals to confirm it is working properly.
I had not given it a thought that someone would be so stu... to just download a w&b spredsheet and start using it without confirming its accuracy and adapting it to his own aircraft. Good pointer
So pd2, where's the fuel calulator you were talking about?
