Subject: Pietenpol-List: E.W.C.G. aft of L. E.I thought it would be informative to compare where the Empty Weight Center of Gravity lies in the various aircraft in our Pietenpol Fleet, - an important safety item. Normally, E.W.C.G. is a distance from the Datam. This has provento be quite a challenge, for the following reasons:1) The plans call out the Datam for the Pietenpol - is the Firewall, however, the Firewall is not always used as the Datam - although it should be.2) Wings are placed at various distances from the firewall, therefore to determine the E.W.C.G. behind the L.E., (with the firewall as the datam) this distance must be subtracted.3) Forward fuselages are not all the same.4) Empty Weight Center of Gravity is the base line for the various loading conditions.Conclusion: The easiest way to compare E.W.C.G. is to list it as a distance behind the leading edge, therefore in the 'Infomation Sheet' I've listed it as - 'Empty C. G. aft of Leading Edge'. Chuck GantzerNX770CG________________________________________________________________________________
