Bane bareba mbere yose, reba coefficiete. Gutesha agaciro bigena torque yibanze yinkombe ya feri. Ikirenga cyane kizatera ibiziga gufunga, gutakaza icyerekezo no gutwika padi mugihe cya feri. Niba ari hasi cyane, intera ya feri izaba ndende cyane; Umutekano, feri yuzuye izabyara ubushyuhe bwihuse mugihe cya feri, cyane cyane mugihe cyo gutwara ibintu byihuta cyangwa feri yihutirwa, amakimbirane yihutirwa yo guterana amagambo azagabanuka munsi yubushyuhe bwinshi; Icya gatatu, reba niba ari byiza, harimo gufatanya ibyiyumvo, urusaku, umukungugu, nubushyuhe. Umwotsi, impumuro yihariye, nibindi, ni ukugaragaza mu buryo butaziguye imikorere yiterambere; Bane reba ubuzima, mubisanzwe feri pad irashobora kwemeza ubuzima bwa serivisi ya kilometero 30.000.
Amahitamo abiri: Ubwa mbere, ugomba guhitamo padi ya feri yakozwe numuyoboro usanzwe, hamwe numubare wihariye uhuza, hamwe numero yimodoka, itariki yumusaruro, nibindi .; Icya kabiri, hitamo kubungabunga umwuga ubaze umunyamwuga wo kuyishiraho.
