Totally agree with you Gomer Pylot. The electronic W&B are a very useful and time saving tool. I use them for every flight.
My criticism is directed to the almost desperate requests for these tools, which makes these tools seem like some sort of Holy Grail.
My point is that pilots should be able to do these for themselves. All that is needed is a basic knowledge of Excel or other spreadsheet program.
If I download one of these programs listed on the thread, how do I know it is correct and/or accurate? I am sure that more than a few will probably just download the program and start plugging away with figures for their flight and probably not even check correct BEW, arms and moments specific for their aircraft.
