O ob peb lub lis piam dhau los, kev tshaj xov xwm tau raug dej nyab nrog cov duab thiab yeeb yaj kiab ntawm cov hluav taws kub hnyiab uas kub hnyiab thoob plaws Asmeskas sab hnub poob, suav nrog kev pom zoo nkauj ntawm lub qhov rais dav hlau. Tom qab ntawd, hnub Monday, Alaska Airlines tau ncua tag nrho cov kev khiav haujlwm hauv Portland thiab Spokane rau 24 teev vim muaj huab cua txaus ntshai. Peb xav tias peb tsis yog tib leeg xav paub: Puas muaj kev nyab xeeb rau cov dav hlau ya los ntawm cov pa taws kub hnyiab?

"Cov dav hlau ua lag luam ya los ntawm cov pa luam yeeb me me thiab nruab nrab yam tsis muaj teeb meem nyob rau hauv feem ntau," aerospace engineer Ben Frank, tus tsim ntawm lub tuam txhab kho dav hlau software Rotabull, hais rau TripSavvy. "Txawm li cas los xij, volcanic tshauv lossis cov pa luam yeeb tuab tuaj yeem ua rau pom kev pom thiab huab cua tsis zoo, ntxiv rau kev ua haujlwm ntawm lub dav hlau tsis zoo."

Nws tag nrho boils mus rau cov pa luam yeeb. "Cov pa taws los ntawm cov hluav taws kub hnyiab muaj cov sib txawv xws li cov pa roj carbon monoxide, cov tshuaj tsis hloov pauv hauv cov organic, carbon dioxide, hydrocarbons, thiab nitrogen oxides, uas nyob deb ntawm kev phom sij ntawm cov tshauv hluav taws kub," piav qhia José Godoy, CEO ntawm lub tuam txhab ua haujlwm davhlau Simpfly. "Volcanic ashes yog tsim los ntawm me me ntawm pob zeb, minerals, thiab volcanic iav, uas yog tawv thiab abrasive."

YogThaum cov pa luam yeeb feem ntau tau rub los ntawm lub tshuab dav hlau yam tsis muaj teeb meem, cov khoom ntawm volcanic tshauv tuaj yeem ua rau qhov sib txawv ntawm lub dav hlau. Tias yog vim li cas huab cua hauv Tebchaws Europe tau raug tso tseg thaum xyoo 2010 tawg ntawm Eyjafjallajökull hauv Iceland, tab sis feem ntau ntawm cov huab cua nyob rau sab hnub poob ntug dej hiav txwv, uas tsis yog lub caij luv luv los ntawm Alaska (uas yog ntau rau kev noj qab haus huv ntawm cov neeg ua haujlwm hauv av dua li cov dav hlau lawv tus kheej), feem ntau tau txuas ntxiv li qub.

Lwm yam xov xwm zoo yog tias koj tsis tas yuav txhawj xeeb txog cov pa taws nkag mus rau hauv chav tsev thaum koj ya hla nws, txawm tias koj yuav hnov nws. "Cabin huab cua yog kwv yees li 50-50 qhov sib xyaw ntawm cov pa tawm thiab sab nraud. Cov huab cua rov qab hla dhau los ntawm cov tshuab ua haujlwm zoo heev, thiab hloov pauv txhua ob peb feeb, "hais Frank. "Sab nraum cov huab cua, xws li cov pa luam yeeb, uas nkag mus rau hauv lub tsev yuav raug lim tawm sai heev los ntawm HEPA cov ntxaij lim dej nyob rau hauv ob peb lub voj voog rov ua dua." (Rau qhov nws tsim nyog, cov ntxaij lim dej no tseem tuaj yeem tshem tawm COVID-19 los ntawm huab cua, ib yam nkaus-lawv yog tib hom lim siv hauv tsev kho mob.)

Muaj ib kis, txawm li cas los xij, hauv cov dav hlau yuav tsis ya los ntawm pa taws. Qee qhov hluav taws kub hnyav tshaj plaws tuaj yeem tsim tau huab cua pyrocumulonimbus, cua daj cua dub uas tsim los ntawm cov cua sov thiab cov pa taws, uas NASA hais tias yog "tus huab cua ua pa ntawm huab cua." Cov no yog ib qho tsis mus rau lub dav hlau, tab sis tsis yog vim cov pa taws nws tus kheej: dav hlau zam txhua yam cua daj cua dub, suav nrog cov hluav taws kub hnyiab, vim tias huab cua tsis zoo heev tuaj yeem ua rau muaj teeb meem loj.aircraft, nws cov neeg coob, thiab nws cov neeg caij tsheb.
