4、Tuhinga Whakapuru
1) Te pāmahana hau ambient
1) Ma te whakaaro ki te nui o te pāmahana ambient ki te whakatere i te koroheketanga o nga waahanga kirihou, ko te rohe o runga kaore e neke ake i te +40 ℃.
Ki te whakaaro ko te tino iti rawa te pāmahana ambient
ka huri i te pai o te mema hanganga, ko te rohe o raro kaore i raro iho i te -5 ℃.
Ma te whakaaro ki te oranga o te kaiawhina, ko te uara toharite o nga haora 24 kaua e neke ake i te +35 ℃.
Tuhipoka:
① Ko te ahua mahi o te uara rohe iti ko -10 ℃, -25 ℃ ranei.Me whakaatu te kaiwhakamahi ki te kamupene ina ota.
②Ko te ahua mahi o te uara rohe o runga ake i te +40 ℃ ranei te uara rohe iti iho i raro i te -25 ℃, me whiriwhiri te kaiwhakamahi me te kamupene.
2)Wāhi Tāuta
Ko te teitei e kore e neke ake i te 2000m;
Nga whakaritenga ara iahiko tiaki;
Ko te waahi whakaurunga ka tatau i te iahiko poto Ik kaua e neke ake i te 3000A;
Ka whakauruhia te kaitarai hiko kia rite ki nga whakaritenga o te whakamahinga o te pukapuka, ko te kohanga poutū o te kaitarai hiko kaua e neke ake i te 5 °, Ko te wiri o te taiao e kore e neke atu i te 5g.
3) Nga Tikanga Ahurangi
Ko te haumākū whanaunga o te kōhauhau e kore e neke atu i te 50% i te pāmahana rangi ambient +40 ° C. Ka taea e te reira i te haumākū whanaunga teitei i te pāmahana iti.Ko te haumākū whanaunga o ia marama o te marama mākū ko 90%, me te toharite pāmahana iti mo te marama ko +25 ° C me te whai whakaaro tōhau i runga i te mata o te hua e tika ana ki te huringa pāmahana.
4) Te taumata parahanga
Ko te taumata parahanga he taumata 3.
5) Kāwai Tāuta
Ko te ara iahiko whakamaru i te ara iahiko kua whakauruhia ki te waahanga III.
1) Kua whirihorahia te waahanga whakawhiti waea kia rite ki te nui o te whakamahana tikanga o naianei Ith o te waahi ara iahiko.
