Izakhiwo zokuxhoma iinqwelo-moya ezilungiselelwe kwangaphambili lunye uhlobo lwezakhiwo zentsimbi ezenziwe zaza zaveliswa kwiifektri kwaye zithunyelwa kwiindawo zokwakha, zilungele ukuhlanganiswa. Emva kokuba zakhiwe, izakhiwo zentsimbi ezenziwe ngobunjineli zangaphambili ziya kuhlangana nezinye ezininzi zohlobo lwazo kulo lonke ilizwe ezazakhiwe ngomlinganiselo omkhulu kuphela kwiminyaka yakutshanje. Ngokusetyenziswa kwetsimbi, ukuveliswa kunye nokwakhiwa kwezakhiwo zensimbi ezenziwe ngaphambili kulula kakhulu kwaye ungakhankanyi, ngokukhawuleza. Ukuthuthwa kwezixhobo kwenziwa lula kakhulu, kuqwalaselwa ukuba intsimbi yinto eqhelekileyo enobunzima. Okothusayo, kuthathelwa ingqalelo ukuba sesinye sezona zixhobo ziyomeleleyo ngeenxa zonke.

I-Beisdes idibana neekhowudi zokwakha, iikhowudi zokwakha zentsimbi, siya kuzama konke okusemandleni ethu ukuyila kunye nokwenza ii-hangars zeenqwelomoya ezenziwe ngaphambili ngeendleko eziphantsi kunye nokugcina amandla.

Iimfuno zabathengi, iimeko zokusingqongileyo (ezifana ne-seismic zone, umthwalo wemvula, umthwalo wekhephu, umthwalo womoya, njl.njl.), ubungakanani bomhlaba zezona zinto ziphambili, eziqwalaselwa ziinjineli zethu kunye nabayili.

Sineendawo ezininzi zokwakha zokhetho lwakho, unokukhetha enye ngokobungakanani be-hangar yenqwelomoya.
