Tus kws tsav dav hlau puas tuaj yeem tsaws lub dav hlau?
Thaum muaj xwm txheej ceev, nws yuav yog lawv txoj haujlwm los tsaws lub dav hlau kom nyab xeeb thiab lawv yuav tsum tau npaj los tuav lub dav hlau tswj txhua lub sijhawm. Lwm qhov nyuaj ntawm kev ua haujlwm raws li tus neeg tsav nkoj yog lub sijhawm. Ib yam li lwm tus neeg caij dav hlau, cov neeg tsav dav hlau yuav tsum siv sij hawm ncua deb ntawm tsev.
Vim li cas ob tus neeg tsav dav hlau hauv lub cockpit tseem tseem ceeb?
Qhov laj thawj tseem ceeb ntawm kev muaj ob tus neeg tsav dav hlau hauv txhua lub davhlau yog kev nyab xeeb Pom tseeb, yog tias muaj qee yam tshwm sim rau tus thawj coj, lub dav hlau yuav tsum muaj lwm tus kws tsav dav hlau uas tuaj yeem nkag mus. thawj tus tub ceev xwm muab tswv yim thib ob ntawm kev txiav txim siab tsav tsheb, ua kom tus tsav ua yuam kev kom tsawg kawg nkaus.
Dab tsi yog ob hom kev tsav tsheb tsis muaj peev xwm?
Kev tsis muaj peev xwm tau muab faib ua ob pawg: Pom tseeb (feem ntau poob ntawm kev ua haujlwm). Hloov maj mam (feem ntau yog ib feem poob ntawm kev ua haujlwm). Pom tseeb qhov tsis muaj peev xwm feem ntau tam sim ntawd, feem ntau ntev thiab feem ntau ua rau poob ntawm kev ua haujlwm tiav.
