I've had a look at the sheet in some more detail. The following overlay is based on an analysis to make the fuel grid correct so far as the IU equati...
Two random comparison examples - (a) starting data weight = 3800 kg CG = 4700 mm From a looksee through my archives, this is probably a reasona...
As Bob indicates, TODA is the relevant figure for light aircraft calculations. However, there is a sideline caveat re TORA/TODA. It probably w...

I've now had time to undertake a preliminary review of the sheet and it appears to have a number of significant errors/variations from what one would ...
Well done, that man. Parallel sides on the CG envelope in a trimsheet are an instant red flag. It is premature to say that the sheet is in error ...
