The area enclosed by an ellipse is πab, where 'a' and 'b' are the semimajor and semiminor axes and π is Archimedes's constant. In the case of a circle where a = b, the expression reduces to the familiar πa2.

m) During the refuelling and the restart of the motor, and until the time when he releases the model aircraft, the mechanic must keep the model aircraft in contact with the ground by at least one point and with the centre line outside the flight circle. During that time the pilot must be crouching or sitting inside the centre circle. He keeps one hand on the ground and his handle and his lines as close to the ground as defined by the F2C panel of judges until the model aircraft starts again.
