YT29A Rere-Waewae Toka Drill
Āhuahira:
Ko te YT29A te kaha o te hau pupuhi, me te mahinga whakahaere matua, te tiimata ngawari, te honohono o te hau-wai, te whakamahi pai, te tiaki ngawari, te haruru iti, te wiri iti, te penapena hiko me te tino pai, te roa o te ratonga o nga waahanga, te whai kiko, te pai o te pono, te tino pai, te mahi kaha o te horoi i nga kohao pupuhi me te taipana hurihuri nui, na reira kei te awangawanga mo nga hua rite.Kei te nuinga whakamahia te reira mo te keri, ngingio me te punga taura rua i roto i te toka engineering whenua.
Taupānga:
kohanga me te tautoko i roto i te maina, te kawe waka, te tiaki wai, te hiko wai me etahi atu kaupapa.Ko te nuinga o te waa e whakamahia ana mo te keri - wehewehe toka.
Ko a maatau whakangungu toka-waewae e whai ake nei nga ahuatanga:
1. He pai mo te keri maku i roto i te toka reo-pakeke, toka maro ranei
2. Ko te tikanga whakahaere whakarōpū, he tere ki te tiimata, me te "hau ki runga, ki te wai, ki runga, ki te hau, ki te wai", he pai ki te hapai me te ngawari ki te tiaki me te whakatika.
