Gear Swing in LIVP: Change to
CG?
Question about Center of Gravity (CG) change with swinging the
gear in the Lancair IVP.
The manual gives an moment (inch-arm) change of 1516 in-lbs,
which results in a CG move aft of 0.50" when gear is retracted at
~3000 lbs. At 2350 lbs, this changes the CG 0.65"
aft.
I was recently told the actual change is 1.22"
measured.
Has anyone else measured the actual CG change with gear
swing (at empty weight)?
