Jadwalka 80 tubada birta kaarboon waa nooc ka mid ah tuubooyinka lagu garto gidaarkeeda dhumuc weyn marka loo eego jadwalada kale, sida Jadwalka 40. "Jadwalka" tuubada waxaa loola jeedaa dhumucdiisa derbiga, taas oo saameynaysa cadaadiska cadaadiska iyo xoogga qaabdhismeedka.
Astaamaha Muhiimka ah ee Jadwalka 80 Dhuumaha Birta Kaarboon
1. Dhumucda gidaarka: Waa ka sii dhumuc weyn yahay Jadwalka 40aad, kaas oo siinaya xoog iyo adkeysi weyn.
2. Qiimaynta Cadaadiska: Qiimaynta cadaadiska sare sababtoo ah dhumucda darbiga oo kordhay, taas oo ka dhigaysa mid ku haboon codsiyada cadaadiska sare.
3. Qalabka: Waxa laga sameeyay birta kaarboon, kaas oo bixiya awood wanaagsan iyo adkeysi, sidoo kale iska caabbinta xirashada iyo jeexjeexa.
4. Codsiyada:
Tuubooyinka Warshadaha: Waxaa loo isticmaalaa warshadaha sida saliidda iyo gaasta, farsamaynta kiimikada, iyo korontada.
Tuubooyinka: Waxay ku habboon yihiin khadadka biyaha ee cadaadiska sarreeya.
Dhisme: Waxaa loo isticmaalaa codsiyada qaab dhismeedka halkaas oo xoog sare looga baahan yahay.

Faa'iidooyinka
Xoog Sare: Darbiyada qaro weyn waxay bixiyaan hufnaanta qaabdhismeedka oo la xoojiyay.
Waarta: Adkaanshaha birta kaarboon iyo adkeysiga xirashada ayaa ka dhigaya tuubooyinkan mid waara.
Kala duwanaansho: Waxay ku habboon tahay codsiyo iyo warshado kala duwan.
Khasaaraha:
Miisaanka: Darbiyada adagi waxay ka dhigaan tuubooyinka kuwa culus oo suurtogal ah inay aad u dhib badan yihiin in la xakameeyo lana rakibo.
Qiimaha: Guud ahaan waa ka qaalisan yihiin tuubooyinka gidaarada khafiifka ah leh sababtoo ah isticmaalka alaabta oo kordhay.
