Ua hoʻolaha ʻo Alaska Airlines i kēia lā ke hoʻohana nei ʻo ia i nā ea ea ma ka honua no ka hoʻokuʻu ʻana i ka hale, ka hoʻoluʻu a me ka wela ma nā mokulele i hoʻopaʻa ʻia ma kahi kokoke i kona mau ʻīpuka ma Seattle-Tacoma International Airport. Ua hoʻolaha aku ka mokulele ua hoʻihoʻi ʻo ia i kāna mau 737 āpau i hiki ke hoʻohana i nā winglets hui ʻia. ʻO nā papahana ʻelua ka mea hou loa i loko o kahi pūʻulu o nā hana e hoʻomau ʻia e ka mea lawe e mālama i ka wahie a hoʻemi i ka hoʻoiho kalapona.

Mai ka makahiki 2002, ua hōʻemi kēia mau hana i ka nui o ka wahie e hoʻohana ai ʻo Alaska Airlines no ka lawe ʻana i hoʻokahi mea holo i hoʻokahi mile ma ka 17 pakeneka. ʻO ka hoʻemi ʻana o ka hoʻokuʻu ʻana o carbon dioxide e like me ka lawe ʻana i 130,000 mau kaʻa mai ke alanui no hoʻokahi makahiki.

ʻO nā ʻea ea i hoʻopaʻa mua ʻia i ka diesel, me ka mana uila ma luna o ka honua, e hoʻololi i ka hoʻohana ʻana i ka mana kōkua ma luna o ka mokulele (APU), e holo ana ma ka wahie mokulele. ʻO nā ʻāpana i hoʻokumu ʻia i ka ʻāina e puhi ma kahi o 10 mau manawa liʻiliʻi o ka wahie ma mua o nā APU, ʻo ia hoʻi e hōʻemi nui nā ʻāpana hou i nā kumukūʻai a pōmaikaʻi i ke kaiapuni ma ka hoʻohaʻahaʻa ʻana i nā hoʻokuʻu kalapona.

Ma ke kahua mokulele ʻo Sea-Tac, ʻo ka hoʻohana ʻana i nā ea i hoʻopaʻa mua ʻia ma nā ʻīpuka he 19 e manaʻo ʻia e mālama ʻoi aku ma mua o 1.1 miliona mau galani wahie i kēlā me kēia makahiki, e mālama ana i ka hui $ 2.6 miliona i kēlā me kēia makahiki ma muli o ke kumu kūʻai o ka paila o kēia manawa, wahi a Kristin Fuson, kahi mokulele Alaska Airlines. 'enekinia hana a me ka luna papahana. ʻOiai e puhi ana nā ʻāpana i ka wahie diesel, e hoʻemi ʻia ka hoʻokuʻu ʻana o carbon dioxide e 24 miliona paona i kēlā me kēia makahiki ma muli o ka emi ʻana o ka wahie, wahi a Fuson.

ʻOi aku ka ʻoi aku o ka mālama ʻana i kēlā me kēia makahiki ma mua o ka pālua i ka 2.4 miliona galani wahie a me $5.5 miliona i ka manawa i hoʻopaʻa ʻia ai nā ʻāpana ma nā hui ʻē aʻe o Alaska Airlines ma Anchorage, LAX, Portland a me Kapalakiko ma hope o ka makahiki.

"Ke neʻe nei ʻo Alaska Airlines i ka hoʻohana ʻana i nā ʻāpana ea honua no kahi o ʻelua makahiki. ʻOi aku ka maikaʻi o nā ʻāpana me nā kumukūʻai aila e lele ana ma kahi o $135 i ka barela, "wahi a Fuson.

“Ua kūʻai a hoʻolimalima paha ka mokulele i 33 mau ʻea mokulele no nā mokulele ʻelima. ʻOiai me ke kumu kūʻai mua o $65,000 no kēlā me kēia ʻāpana, uku nā mīkini iā lākou iho ma kahi o 11 mau makahiki, "wahi a Fuson. Inā kūleʻa ka pāhana, e kūʻai ʻia nā ʻāpana hou aku no nā mokulele ʻē aʻe. E hoʻomaka ana i ka mahina ʻo Kepakemapa, e hoʻokomo ʻia kekahi mau ʻāpana paʻa i nā hub a pau. Hoʻohana ʻia nā ʻāpana paʻa e ka uila mai nā mokulele a ʻaʻole e puhi i ka wahie a i ʻole e hoʻokuʻu.

Ma mua o kēia mahina, ua hoʻopau ʻo Alaska Airlines i ka hoʻoponopono hou ʻana i kāna mau 737 āpau i hiki ke hoʻohana i nā winglets hui ʻia. Hāʻawi ʻia nā mokulele hou āpau me nā winglets i hui ʻia.

Hoʻomaikaʻi ʻo Winglets i ka pono wahie o ka mokulele a hoʻemi i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo ma kahi o 3 pakeneka - a i ʻole he 100,000 mau galani i ka makahiki no kēlā me kēia mokulele. Hana ʻia nā winglets e ka Boeing Aviation Partners ma Seattle. Ma ka hopena o kēia makahiki, e lele ana ʻo Alaska Airlines i 74 Next-Generation 737s me nā winglets, e hōʻike ana i ka 64 pakeneka o kāna mau ʻauwaʻa mokulele 116.

"ʻO ke kūlana gula i nā winglets, kā mākou ʻenehana ua hoʻopakele i ka ʻoihana a me ke kaiāulu honua ma mua o 1 biliona galani wahie a hiki i kēia lā me ka manaʻo e hoʻopakele wahie hou aku ma mua o 175 miliona mau galani ma 2008," wahi a Joe Clark, Aviation Partners Boeing hoʻokumu a lunahoomalu. "ʻAʻohe hoʻololi mokulele ʻē aʻe e hāʻawi i ka mālama wahie a me nā pōmaikaʻi eco-friendly o kā mākou ʻenehana winglet hui ʻia."

Ua hana ʻo Alaska Airlines i kekahi mau hana mālama wahie ʻē aʻe i ka makahiki i hala. Ma waena o lākou, ke wikiwiki nei lākou i ka hoʻomaha ʻana o kā lākou MD-80 e lele wale i ka wahie-efficient 737s. ʻEhiku mau MD-80 i koe o ka mokulele e lawe ʻia mai ka lawelawe ʻo ʻAukake 25 ma mua o ka hopena o Dekemaba, e like me ka mea i hoʻolālā mua ʻia. Eia hou, ke hoʻohana nei lākou i hoʻokahi mīkini i ka wā e hoʻokele ai i nā mokulele no ka mālama ʻana e mālama i ka wahie.

Ke hoʻohana nei nā mokulele i ka hoʻokele satellite. Mai ka makahiki 1996, ua hoʻokumu ʻo Alaska Airlines i kahi ʻenehana i kapa ʻia ʻo Required Navigation Performance. Hiki i ka RNP ke lele pololei i nā ala pololei me ka pololei a hōʻemi i ka hoʻololi ʻana ma muli o ke aniau ma o ka hoʻohana ʻana i ka ʻenehana hoʻokele moku a me ka pūnaewele ukali Global Positioning System. Hoʻohana ka mokulele i ka RNP ma nā mokulele mamao a me ka hoʻokūkū ʻāina a puni ka mokuʻāina o Alaska, a me Portland, Oregon; Kapalakiko; ʻO Palm Springs, Kaleponi a ma Reagan National Airport ma Wakinekona, DC.

Ke hoʻohana nei lākou i nā kaʻa ʻai māmā māmā. Mai ka hoʻihoʻi hou ʻana i kāna mau mokulele me nā kaʻa māmā māmā i Kepakemapa 2006, ua mālama ka mokulele i kahi kokoke i 300,000 galani wahie i kēlā me kēia makahiki.

Hāʻawi pū ʻo Alaska Airlines a me Horizon Air i nā kūlanakauhale he 94 ma o kahi pūnaewele ākea ma Alaska, Lower 48, Hawaii, Kanada a me Mexico.
