4. Aerobatic Airspace: 4.1: X-Axis and Y-Axis The X-Axis is the main axis of flight, parallel to the flight line. The Y-Axis is perpendicular to the X-Axis (flight line). 4.2: Deadline. The ―Deadline‖ is located 100 feet (30.5 meters) in front of the contestant. This line delimits the ―no-fly‖ zone for safety reasons. The judges shall zero (0) any maneuver where the aircraft completely crosses this deadline. 4.3: Airspace Control Score Judges will evaluate each individual sequence flown, in its entirety, for overall airspace control. Each judged Known and Unknown sequence, shall have one ―figure‖ added to the end of the score sheet, after individually judged maneuvers. This figure shall be known as the Airspace Control Score and will be SCA-10 assigned by each judge. The Airspace Control Score will have a K value dependent on the class flown. This score will then be multiplied by the K Value for the individual class. The following standard will be used for accessing the pilot‘s performance in maintaining control and awareness of the aerobatic airspace and placing figures in the airspace in a manner that allow the figures to be optimally judges. The highest standard for Airspace Control will be the pilot that exhibits a significant ability to control the location of the aircraft inside the airspace, relative to the judges, which results in a tight footprint and has the aircraft such that it can be optimally judged at all times. The pilot that exhibits excellent airspace control should receive a ten (10). The lowest standard for Airspace Control will be the pilot that exhibits a poor ability to control the location of the aircraft inside the airspace, relative to the judges, which results in an excessively large footprint and has the aircraft consistently so far away as to be difficult to properly judge. The pilot that exhibits very poor airspace control should receive a zero (0). Pilots exhibiting airspace control within the range of these two standards will be graded with a range of possible scores from ten (10) to zero (0) in whole point increments. The K factors for the Airspace Control Score are: Basic = 3K Sportsman = 6K Intermediate = 9K Advanced = 12K Unlimited = 15K
