1) Idizayini yobuhle eyingqayizivele: Ingilazi yephrofayela ye-U, enomumo wayo oyingqayizivele, inikeza amathuba amasha ngokuphelele edizayini yezakhiwo. Amajika aso amahle nemigqa eshelelayo angeza umuzwa wesimanje kanye nobuciko esakhiweni, kusenze sibukeke sithandeke futhi sibe nomthelela.

2) Ukusebenza okuhle kakhulu okonga amandla: Ingilazi yephrofayili ye-U isebenzisa ubuchwepheshe obuthuthukisiwe bokukhiqiza nezinto zokwakha futhi inokusebenza okuhle kokufakwa kwe-thermal. Umumo waso oyingqayizivele kanye nesakhiwo sesakhiwo kusiza ekwehliseni ukudluliswa kokushisa nokulahlekelwa, ngaleyo ndlela kuncishiswe ukusetshenziswa kwamandla kwesakhiwo nokufeza umgomo wokonga amandla nokunciphisa ukungcola.

I-3) Ukusebenza kahle kokukhanyisa: Ingilazi emise okwe-U iqoqa kahle futhi ihlakaze ukukhanya kwemvelo, okwenza indawo yangaphakathi ikhanye futhi ikhululeke kakhudlwana. Ngasikhathi sinye, ukusebenza kwayo kokudlulisa ukukhanya kungcono futhi kunokwengilazi yendabuko, kuhlinzeka ngolwazi olungcono lokubukwayo ukuze abantu bakwazi ukujabulela ukukhanya kwelanga kwemvelo ngaphakathi endlini.

I-4) Ukusebenza kwesakhiwo okuqinile: Ingilazi emise okwe-U iqine kakhulu futhi izinzile futhi ingamelana nomfutho womoya obalulekile nomthwalo. Idizayini yayo yephrofayili eyingqayizivele iphinde ikhulise indawo yokuxhuma phakathi kwengilazi nohlaka, ithuthukise ukuzinza nokuphepha okuphelele.

I-5) Ukusimama kwemvelo: Enqubweni yokukhiqiza ingilazi engu-U, izinto ezihambisana nemvelo nezinqubo zinganciphisa umthelela wemvelo. Ngesikhathi esifanayo, ukusebenza kwayo okuhle kakhulu ukonga amandla kuphinde kusize ekunciphiseni ukukhishwa kwekhabhoni yezakhiwo, kuhambisane nentuthuko yezakhiwo zesimanje eziluhlaza.

I-6) Ukufakwa nokugcinwa kalula: Ukuklanywa kwengilazi efana ne-U kwenza kube lula kakhulu ekufakeni, ukunciphisa isikhathi sokwakha kanye nezindleko. Ngesikhathi esifanayo, ngenxa yobuningi bempahla yayo, ukuhlanza, nokugcinwa kwayo kulula, kunciphisa izindleko nobunzima bokugcinwa kamuva.

Ukufingqa, ingilazi yephrofayili ye-U isiphenduke into ebaluleke kakhulu ekwakhiweni kwezakhiwo zesimanje ngenxa yedizayini yayo yobuhle eyingqayizivele, ukusebenza okuphezulu okonga amandla, ukusebenza kahle kokukhanya, ukuqina kwesakhiwo, ukusimama kwemvelo, kanye nokufaka nokulungisa kalula.
