Ukucutshungulwa kokubhola kwenetha lokuphepha kanye nomshini we-CNC
Inethi yokuphepha iyinethi yokuvikela eyakhelwe ophahleni lwezakhiwo eziphakeme kanye ne-helipad ukuvimbela ukuwa nokuvikela ukuphepha kwezindiza ezinophephela emhlane. Inezinhlobo ezimbili: inethi yokuphepha kagesi kanye nenethi yokuphepha esetshenziswa ngesandla. Inzuzo yenethi yokuphepha kagesi isivinini sokuphendula esisheshayo, esingalawulwa kude ngokucindezela inkinobho. Ifanele izikhathi zokuhlenga eziphuthumayo kanye ne-helipad, kodwa ububi yizindleko eziphakeme, ezidinga ukuhlolwa njalo nokugcinwa kwemoto. Inzuzo yenethi yokuphepha esetshenziswa ngesandla ukuthi izindleko ziphansi, futhi ububanzi bokuphakamisa inethi yokuphepha bungalungiswa ngesandla nangokukhululekile. Manje ividiyo yokubhoboza inethi yokuphepha iyenziwa, ukuze izikulufu zidlule enethini yokuphepha futhi zifakwe ohlakeni lwekholomu, oluqinile kakhulu futhi olungawi, okwandisa ukuphepha kwenethi yokuphepha.
