Performing a set of figures in free fall

For a clear and safe execution of the complex of figures, the paratrooper must:

On the ground:

develop a detailed jump model;
firmly master your actions at every second of the jump;
know the separation point, passage time and magnetic course.
When climbing:

mentally lose several times the entire jump elementwise and per second;
check the locks of the USC, the mounting of the reserve parachute and the position of the ring of the reserve parachute;
check the operation of the stopwatch and altimeter.
Before separation:

clarify the approach of the aircraft, find signs and separation points on the ground;
focus on the implementation of a given complex.
After separation:

The first stage is acceleration (10-12 s), the second is the horizontal position and grouping (1-2 s), the third is the implementation of the complex (or preparatory figures):

Before starting the complex, check your position relative to the horizon and signs, the position of your hands and feet and energetically start the first spiral;
performing the second spiral, pay all attention to the spiral-flip-spiral-ligament and do not forget about the position of the legs;
to perform deeper braking on the second spiral with the support arm withdrawing a little forward, ending the second spiral, prepare the hands for a somersault, fully select the legs;
perform a somersault at the expense of hands with legs fully retracted, at the entrance to a somersault, pull up your legs to the reserve parachute, perform braking after passing the vertical axis to exit to the horizontal position only with your hands, your knees should be firmly pressed to the reserve parachute, 30 ° to the horizontal position give the hands the position necessary to enter the left or right spiral;
perform the fourth spiral similarly to the second;
the first 3/4 of the final second somersault is identical to the first one, and then, when approaching the horizon for 30-45 °, fully open and fix the horizontal position with your head on the signs;
create the most favorable position for opening the main parachute and pull out the exhaust ring.
Typical errors

incorrect calculation of the separation point (signs are too far or too close), which creates inconvenience in the implementation of the complex and holding the group;
entanglement of the complex due to poor preparation for the jump or lack of assemble before the jump;
untimely braking at the exit from the figure;
delay time delay;
incorrect position of the legs in the group during the execution of the complex;
lack of clarity in the execution of figures due to excessive haste.
Security measures

Prudence and attentiveness when performing a jump.
The correct height setting on the insuring device and its inclusion when separating with an exhaust halyard.
Availability and serviceability of a stopwatch and altimeter.
Check before operation of the serviceability of the OSK locks, fastening of the reserve parachute, the position of the exhaust ring of the main and reserve parachutes, the condition of the equipment and clothing of the parachutist.
The ability to count down the delay time in the mind when the stopwatch and altimeter fail.
Control of the entire jump from the ground with the help of TZK.
Timely and clear use of a reserve parachute in the event of a main failure.
