Reading about orbital manoeuvres, I found a few reference to the "Broken Plane Manoeuvre".
One illustration describes it:
From what I understand, it is called life this because the burn which appear to instantaneous when scaled towards a sun orbit, appear to be broken.
In that sense, any manoeuvre that include a plane change is a "broken plane".
Any manoeuvre (with sufficient thrust) should appear broken the same way.
Do I understand correctly ? Why do we use the adjective "broken" only for plane (inclination) changes ?
