Event I: Individual precision-landing jump from an altitude of 1,000 meters.

51. Two jumps shall be made. Landing in the center of the circle shall be estimated at 150 points. Each meter away from the center shall reduce the score by one point. For every centimeter away from the center the score shall be diminished by 0.01 point. Each jump shall be estimated separately.

52. The contestants must open the parachute not later than 3 seconds after clearing the plane. If the parachute opens later than 3 seconds, the jump will be considered as executed but the contestant shall not receive any points.

53. The maximum score for these jumps in this event is 300 points.

Event II: Individual jump from an altitude of 1,500 meters for precision landing and style of the free fall, with a 15-23 second parachute-opening delay.

54. Two jumps shall be made. The estimation of the precision of the landing will be the same as for event 1, the maximum score for one jump being 150 points. The style shall be estimated at 150 points at the most for one jump.

55. Execution: Immediately after clearing the aircraft, the contestant shall assume a horizontal position, face down, arms outstretched in the direction of the flight of the plane. He shall maintain this position during the whole of the free fall. After opening the parachute he shall land in the circle.

56. The contestants may open the parachute during the period after the 15th second up to the 23rd second of the free fall. A change of direction by 30 degrees to the right or to the left may be effected during the free fall. The angle of the inclination of the body to the horizontal plane shall not exceed 45 degrees. The style of the free fall shall not be estimated during the last two seconds before the opening of the parachute. The estimation of the precision of the landing will be the same as for event 1. The score for the entire event will be the total sum of the points for the free fall, 150 points at the most, and for the precision of landing, 150 points at the most. The maximum score for one jump shall be 300 points, for both the jumps 600 points.

57. Penalty: If the contestant opens the parachute before a 15second free fall or after a 23-second free fall, he will be fined 50 points. If he opens the parachute below an altitude of 400 meters, he will be excluded from the respective event.

58. For violating style of free fall, the contestant shall be fined: Every second of violation of the horizontal position and of the direction will be fined 5 points; every turn to the side will be fined 5 points; 5 points for every dive or sway; 150 points for back fall, somersault, spiral, spin or disorderly fall.

Event III: Individual jump from an altitude of 2,500 meters, with 35-43 second free fall, execution of figures and estimation of style.

59. Two jumps shall be made. Execution: After clearing the aircraft the contestant shall within 5 seconds assume a horizontal position, face down, arms outstretched, in the direction of the arrow. A white arrow, visibly marked on the soil, about 18 meters in length and 2 meters wide, shall be placed on the airfield near the landing place.

60. The way of clearing the aircraft shall be left to the discretion of the contestant. During the free fall, the head of the contestant shall be in the direction of the white arrow.

61. At the 10th second of the free fall, a signal will be displayed by the arrow indicating the complex of turns or figures he has to execute. The signal will be a white tilt about 6 meters in length and 2 meters wide, which will be laid out by the arrow. This signal will be displayed up to the 15th second of the free fall, i.e., during 5 seconds.

62. Immediately after the above signal has been given, i.e., not sooner than at the 10th second of the free fall, the contestant may begin to execute the indicated turns or figures as follow:

    	a. Signal laid out to the left in the direction of flying: two left turns, 360 one right turn, 360 one left turn, 360 two right turns, 360
    	b. Signal laid out to the right in the direction of flying: one right turn, 360 one left turn, 360 two right turns, 360 two left turns, 360
    	c. Signal laid out to the right and to the left side across: one left turn, 360 two right turns, 360 two left turns, 360 one right turn, 360

63. All the turns or figures shall be executed within 20 seconds, i.e., up to the 35th second of the free fall. After every turn or figure the contestant shall revert to the original direction of the arrow. It will be left to the discretion of the contestant whether to execute the turns or figures fluently or separately.

64. Score: The time of the free fall shall not be estimated and the contestant may open the parachute between the 35th and 43rd second of the free fall. The opening of the parachute before the 35th second or after the 43rd second shall be fined 50 points. If the contestant opens the parachute below 400 meters, he will be excluded from the respective event.

65. The style of the free fall shall be estimated at 150 points. Every second of delay in assuming the horizontal position and the direction after clearing the aircraft, even after the completion of the turns, shall be fined 5 points.

66. For violating the style of the free falling the contestant shall be fined: Every second of violation of the horizontal position and of the direction will be fined 5 points, every turn to the side will be fined 5 points; 5 points for every dive or sway; 150 points for a back fall, somersault, spiral, spin or disorderly fall.

67. The execution of a turn or figure will be estimated at 150 points provided the whole complex of turns or figures has been executed. Every turn or figure which has not been completed or which has been increased by more than 45 degrees shall be fined 25 points. The turns shall not be estimated if the contestant fails to execute the prescribed complex of turns or figures according to the signal or if he executes them with an inclination exceeding 45 degrees.

68. In case the whole complex of turns or figures has been completed before the 35th second of the free fall, the contestant shall be awarded 5 points for every second. On the contrary, if he completes it after the 35th second, he will be fined 5 points for every second.

69. Before the aircraft takes off, the contestant shall indicate whether he intends to execute turns or figures. If he does not execute turns or figures he shall maintain the horizontal position in the set direction for the duration of the free fall.

70. The score for the entire event shall be as follows: 150 points for the style of the fall, at the most; 150 points, at the most, for the turns or figures. In addition, the points awarded for the earlier completion. The maximum score for two jumps shall be 600 points and, in addition, the points awarded for the earlier completion of the turns or figures. If the contestant does not execute turns or figures, the maximum score for the two jumps, for the style of the free fall, shall be 300 points.

Event IV: Team jumping from an altitude of 1,500 meters for precision landing with a 15-23 second parachute-opening delay.

71. Every contestant shall open the parachute in the period from the 15th to the 23rd second after clearing the aircraft. Every team shall execute two jumps.

72. Neither the style nor the time of the free fall shall be estimated. The contestant shall not open the parachute before the 15th and after the 23rd second of the free fall.

73. The precision of landing only shall be estimated and the points shall be awarded according to the system indicated for event 1. The maximum score for two jumps shall be 300 points. If the contestant opens the parachute below 400 meters, he will be excluded from this event.

74. Men's teams shall comprise a minimum of 3 and a maximum of 5 contestants. This rule applies to all events. The points shall be awarded with account of the 3 best results. Women's teams shall comprise a minimum of two and a maximum of three contestants. The points shall be awarded with account of the two best results.

75. The score for the entire event shall be made up of a total of the following points:

    300 X 3-900 points for a men's team, at the most.

    300 X 2-600 points for a women's team, at the most.

    The maximum score for both jumps shall be 1800 points for men and 1200 points for women.

76. If a contestant opens the parachute before the 15th or after the 23rd second, his team shall be fined 50 points for every contestant who made this mistake.

77. This event will be taken into account for the total classification of individuals.
