c)Afai o le suʻesuʻega e faʻaalia ai se popolega o le tausisia e le kamupani gaosi oloa talimalo e tatau ona faʻaitiitia le mataupu. O oloa fa'afeiloa'i e fa'aogaina ai le fa'aogaina fa'apitoa e fa'atatau i tulafono fa'apitoa fa'apitoa ta'ito'atasi fa'apea ma tu'utu'uga lautele o le fa'agaioiga i Vaega 15.5, 15.15, ma le 15.29 ina ia aua ne'i fa'alavelave. O le tagata fa'afoe o le oloa talimalo o le a tatau ona taofi le fa'aogaina o le masini se'i vagana ua fa'asa'o le fa'alavelave. - Su'ega fa'aopoopo, Vaega 15 Vaega B fa'ate'aina O le tu'ufa'atasiga mulimuli / module e mana'omia ona iloilo fa'asaga i le FCC Vaega 15B ta'iala mo radiators e le'i mafaufauina ina ia fa'atagaina lelei mo le fa'agaioiga o se masini numera Vaega 15.
Lapataiga FCC:
So'o se Suiga po'o ni suiga e le'i fa'amaonia manino e le itu e nafa ma le usita'ia e mafai ona fa'aleaogaina le pule a le tagata fa'aoga e fa'agaioi ai masini. O lenei masini e tausisia le vaega 15 o Tulafono FCC. O le fa'agaioiga e fa'atatau i aiaiga nei e lua: (1) O lenei masini e le mafai ona fa'alavelave fa'alavelave, ma (2) E tatau i lenei masini ona talia so'o se fa'alavelave e maua, e aofia ai fa'alavelave e ono fa'atupu ai le le mana'omia.
