Vatongi veOakland Center vakamanikidzwa kubata nzvimbo dzakatenderedza FAA nenharembozha dzavo uye kuronga mirairo kundege iyo yakafambiswa nezvivakwa izvi pamusoro peiyo emergency radio frequency.
Zvese izvi zvakakonzerwa nekukanganisa kwea subcontractor izvo zvakakonzera kuti FAA Telecommunications Infrastructure (FTI) system ivhare.
Oakland Center inobata nzvimbo yakakura yemhepo inotenderedza yakawanda yehafu yekuchamhembe kweCalifornia uye zvikamu zvekumadokero Nevada, kuwedzera kune mamirioni mazhinji emamaira emhepo pamusoro pePacific Ocean.
Nhasi, maawa makumi mana nemasere mushure mekudzima kufambiswa kwemashoko, vatongi vendege vari kubvunza iyi mibvunzo yakakosha:
- Sei iyo FAA yakaisa basa rekuchengetedza kweiyi yakakosha hurongwa hwekutaurirana mumaoko ezvibvumirano zvevadiki, pane kuti vashandi veFAA vaite basa?
-Nei vadzori vendege vasina kuudzwa neChipiri nezve basa rekugadzirisa uye nyaya yekuti kudhindwa muhurongwa kwaive patambo yayo yekupedzisira, zvichibva zvaita kuti nzvimbo iyi iiswe pane imwe mhando yekuchenjerera?
-Ndeipi nhanho yekuvimba inofanirwa kuve nevatongi mubasa reava macontractors ayo anokanganisa zvakananga kuchengetedzeka kwevanhu vanobhururuka?
Kudzima kwacho kwakatanga nguva dzinenge 8:00 am PDT kusvika 8:30 am PDT Chitatu. Hapana kumwe kudzima kwakashumwa kubva panguva iyoyo.
Dambudziko rinoratidzika kunge rakatanga neChipiri, apo ma subcontractors aigadzira panharembozha nematambo ekutaurirana akaona dambudziko. Iyo sisitimu yakaiswa pamutsetse wekuchengetedza, asi pakanga pasina chiziviso chakapihwa kune vanodzora mhepo kutyaira chero kuti izvi zviri kuitika uye hapana chiratidzo chakapihwa kuti vatongi vanofanirwa kuve vakangwarira kana system ikavharwa.
Pakutanga Chitatu, panguva yekugadzirisa mitsara yeFTI, kudzoreredzwa kwakavakirwa mugadziriro yekuchengetedza kwakadzika, zvichisiya hafu chete yenzvimbo ine maredhiyo uye kutaurirana kwefoni nezvimwe zvivakwa. Pamusoro pezvo, iyo terminal radar nzira yekudzora zvivakwa inodyidzana nevese Oakland Center uye airport tower controller havana kuwana data ravaida kuti traffic ifambe zvakanaka.
