The airplane shown in the figure starts executing a symmetric pull-up maneuver from steady level attitude with a constant nose-up pitch acceleration of 20 deg/s². The vertical load factor measured at this instant at the center of gravity (CG) is 2. Given that the acceleration due to gravity is 9.81 m/s², the vertical load factor measured at point P on the nose of the airplane, which is 2 m ahead of the CG, is _______ (round off to 2 decimal places).
