  A new phenomenological model FANSY 2.0 is designed, which makes it possible
to simulate hadron interactions via traditional QGSM-type particle generation
as well as coplanar generation of most energetic particles, observed in cosmic
ray experiments. FANSY 2.0 reproduces a lot of LHC (ALICE, ATLAS, CMS, TOTEM,
LHCf) data. Results of model simulations are compared with LHC data. Problems
of coplanarity are considered and a testing experiment is proposed.
