Izibetha zeentaka zaziswa phambi komntu ngoJanuwari 15, 2009, xa i-US Airways Flight 1549 yenze iimeko eziphuthumayo kwi-Hudson River yaseNew York emva kokuhlaselwa ngumhlambi weeCanada emva kokuba usuke e-LaGuardia Airport.
Njengoko iNorth American imoqo yekhephu iyaqhubeka ikhula, ibonakala ngokubanzi kufuphi nemifula ngaphandle kweenqwelo zezikhumulo sezindiza, ngokubhekiselele kwi-Federal Aviation Administration (FAA).
Phakathi kuka-1990 no-2015, ukuxabana kwama-130 okubandakanya i-snow geese kunye neenqwelo zomhlaba zabikwa e-United States, kubandakanywa ezisixhenxe ngo-2015. Phantse amaphesenti angama-85 okuhlaselwa ngexesha lokukhuphuka kunye nezigaba zendiza ezingaphezu kwama-500 kunye neepesenti ezingama-75 zenzeke busuku. A
Ehlabathini lonke, izilwanyana zasendle ziye zabulala abantu abangaphezu kwama-262 kwaye zonakalisa iindiza ezingaphezu kwe-247 ukususela ngo-1988. Inani leenqwelo-moya zase-United States ezihlaselayo zabikwa kwanda ukusuka kuma-334 ngo-1990 ukuya kwiirekhodi ezingama-674 ngo-2015. Iinqwelo-moya ezingama-674 ezihlaselwa ngo-2015 zahlanganiswa 404 zeenqwelo zeenqwelo zeenqwelo .
Uphando lwenziwe yi-FAA kunye ne-USDA ukuphuhlisa iinkqubo kunye nobuchwephesha, kuquka i-ravian nerdar kunye nokukhanyiswa kweenqwelo zezixhobo, ukunciphisa ukuhlaselwa kweentaka zeenqwelomoya. Intlankqalazo yeentaka yintlukwano phakathi kweentaka kunye neenqwelo, kunye neentlobo kunye neengqungquthela phakathi kwalabo abangela umonakalo ngenxa yobunzima nobukhulu babo.
Izinyoni ziyisongelo ekukhuseleni abasebenzi kunye nabagibeli ebhodini njengoko bangenza umonakalo omkhulu kwindiza ngexesha elifutshane kwaye ngamanye amaxesha ukungabi nako kwexesha lokufumana kwakhona kunokukhokelela ekulimaleni okanye ekufeni. Zivame ukuvela ngexesha lokukhutshwa okanye ukufika, okanye ngexesha lokuhamba kwe-low-alt flight, xa i-airplane inokwenzeka ukuba ikwabelana nge-airspace efanayo njengentaka.
Ukukhutshwa kungabungozi ngokukhethekileyo, kunikezwe isantya esiphezulu kunye ne-angle of ascension. Ukuba intaka ibanjelwa kwinjini ngexesha lokukhutshwa kwayo inokuchaphazela kakhulu ukusebenza kweenjini, njengoko kuboniswe kwi-US Airways Flight 1549. Ngokuqhelekileyo, impumlo, injini okanye phambili phambili kwephiko lendiza ziindawo ezichaphazelekayo intaka.
Yintoni ezinokuthi zenze iinqwelo moya ukuba zinciphise iziganeko zeentaka? Ii-Airports zinamaqhinga awaziwa ngokuqhelekileyo njengokulawulwa kweentaka okanye ukulawula iintaka. Iindawo ezijikeleze i-aerodrome zenziwe ngokungenakwenzeka kwiintaka. Kwakhona, izixhobo zisetyenziselwa ukuthusa iintaka - izandi, izibane, izilwanyana ezinqabileyo, kunye neenja ziyimimiselo embalwa.
