<DIV><FONT face=Arial size=2>Hello all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am trying to clarify an idea
about CG location for different weight of a same
airplane. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Goals:</FONT><FONT face=Arial
size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2>Minimize the effect of elevator trim /stab
incidence on level flight, inverted flight and verticals.</FONT></DIV>
<DIV><FONT face=Arial size=2>The airplanes need to fly at the same speed
independent of its weight or the qty of fuel.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Questions:</FONT></DIV>
<DIV><FONT face=Arial size=2>Could it be that a heavier plane need a CG
more AFT than the same plane with a lower weight to "set" in the proper
angle of attack ?</FONT></DIV>
<DIV><FONT face=Arial size=2>Could it be useful to locate the tank so the CG
move FWD as the fuel is burned ?</FONT></DIV>
<DIV><FONT face=Arial size=2>What about CG recommendation on plan or from other
pilots with same plane but different weight ?</FONT></DIV>
<DIV><FONT face=Arial size=2>How much change in angle of attack is required on a
pattern plane for a 2lb difference in weight to fly at the same
speed ?</FONT></DIV>
<DIV><FONT face=Arial size=2>What would be the effect on elevator sensitivity
?</FONT></DIV>
<DIV><FONT face=Arial size=2>Am I going too far ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any opinion ?</FONT></DIV>
