The Forward Physics Facility (FPF) at the LHC will detect neutrinos
produced in proton collisions. In addition to neutrinos from pion
and kaon decays, there will be significant contribution,
particularly for $\nu_e$ and $\nu_\tau$ flavors, from decay
of charmed mesons. We present our predictions for the neutrino
flux from charm decays as evaluated in different QCD approaches:
the next-to-leading order collinear factorization (NLO), and
the $k_T$-factorization approach. We use QCD parameters, such
as the scales, the choice of parton distribution functions,
and the fragmentation function, which were determined from
fitting the LHCb data for D-meson production. We also calculate
the neutrino energy distribution, for neutrinos of all flavors,
that are produced from charmed meson decays. We show that
FPF will be able to provide valuable information about the QCD,
by measuring neutrino flux. We also present our results for the
prompt neutrinos, which are decay products of charmed mesons
produced in interactions of cosmic rays with the atmosphere,
of relevance to IceCube.
