Please refer to section 3.4.3. for general information on the use of BRS systems.
The system installed in YL-MFG is made to work specifically at low heights and slow speeds. The
parachute is pulled out by a specially designed rocket engine. The time required to launch at 95
km/h is 5-6 seconds, depending on the type of system and air temperature. The rocket engine is
placed in the rocket case. After its activation by the handle the movement is mechanically
transported by a Bowden cable on a percussive device, which activates two percussion caps and
they ignite the rocket. After ignition, the rocket escapes under high pressure from the rocket box.
Towing rope of rocket releases the cap of the parachute container, the parachute is pulled from the
container, then the bag of parachute is discarded and parachute canopy is filled with air.
For proper operation, it is necessary to remove the locking pin for the handle before take off. For
tandem airplanes, each pilot has a separate handle, but only the occupied seat handle pin has to
be removed. It is recommended to leave the pin inside the unused handle.

At 650 kg weight, the maximum permissible speed is 320 km/h, if the weight is 600 kg, the
maximum speed is 350 km/h. Minimum recommended height of use is 120 m, but there are noticed
cases of successful application from the lower height than 90 m. It also depends from the
horizontal and vertical components of velocity. System life is 24 years if the revision and repacking
is performed every 6 years.
