COMPOSITE SCORES (SNP)
Pc = Na + Ns + Nf = (Nai + Naf)/2 + (Nsi + Nsa)/2 + (Nfi + Nfa) where,
Pc = pipeline composite Na= composite of phase academics NSS's Ns =
composite of phase simulators NSS's Nf= composite of phase flight NSS's
(Primary composite and NSS information shall be recorded on the CNATRA
