Goal (sport) the ball can be kicked either under the crossbar for a goal, or over the crossbar between the posts for a point. The vertical supports are usually called "goal posts" and the horizontal top is usually called the "crossbar". A goal in these games normally requires that the ball or puck be sent between the posts, under the crossbar and completely behind the goal line. In Australian rules football, there is no crossbar but four uprights instead. In netball, a single post at each end of the court supports a horizontal hoop that the ball must fall through. In basketball,
Position error free-stream pressure is a minimum across the operating range of angle of attack of the aircraft. The residual error at any given angle of attack is called the position error. Position error affects the indicated airspeed and the indicated altitude. Aircraft manufacturers use the aircraft flight manual to publish details of the error in indicated airspeed and indicated altitude across the operating range of speeds. In many aircraft, the effect of position error on airspeed is shown as the difference between indicated airspeed and calibrated airspeed. In some low-speed aircraft, the position error is shown as the difference between indicated
