What regulations apply to changing liveries on private jets in the US?
The only requirement is the height of the registration number, 12" if flying internationally (from the US anyway), 2" I think if staying domestic, and maybe new weight &amp; balance - but usually a layer of paint and primer is taken off, and a new layer is put on, so the weight change is minimal.  Any control surfaces that were removed may need rebalancing.  Colors &amp; schemes are at the whim of the owner(s).
