803. Your radar displays your ship off center. As you proceed on your course, your ship's marker moves on the PPI scope while echoes from land masses remain stationary. What is this display called?

True motion radar displays the ship's movement across the screen while stationary objects, like land, remain fixed; this matches the scenario described in the question where the ship's marker moves and land echoes remain stationary, differentiating it from relative motion displays where the ship is fixed and echoes move, and distinguishing it from displays described as 'off center,' 'head up,' or 'stabilized.'
