Caleen waa dabool (xoogaa yar oo wareejinaya, gabal gabal wareegsan oo ka sarreeya giraangiraha) ee gawaarida gawaarida) iyo gawaarida aan gawaarida ahayn, sida magaceedu ka dhigan yahay, wuxuu daboolayaa qolofka kore ee gawaarida gawaarida iyo gawaarida gawaarida. Iyada oo la raacayo dhaqdhaqaaqa dareeraha, yaree dabka dabaysha caabiga, ha gaadho gaariga inuu si habsami leh u fuulo.
Been-kaard-ka waxaa sidoo kale loo yaqaannaa dahab (oo loo magacaabay qaabka iyo booska qaybtan ee jirka gaariga ee u eg garabka shimbiraha). Taargooyinka caleenku waxay ku yaalliin meel ka baxsan jirka giraangiraha. Hawsha ayaa ah in la yareeyo isku-darka dab-damiska dabaysha iyadoo loo eegayo dhaqdhaqaaqa dareeraha, si gaariga uu si habsami leh u socdo. Sida ku xusan booska rakibaadda, waxaa loo qaybin karaa saxanka hore ee saxanka iyo saxanka gadaal. Plate caleen hore ayaa lagu rakibay dusha sare ee giraangiraha hore. Sababtoo ah giraangiraha hore ee isteerinka ayaa leh shaqada isteerinka, waa inay hubisaa booska ugu badan ee xadka marka ay iswada siinayso. Caleenta dambe waa ka madax banaan tahay isdhaxgalka giraangiraha, laakiin sababaha aerodoynamic, caleen gadaashiisa ayaa leh qaanso yar oo la soo koobay oo ka socda meel ka baxsan.
Marka labaad, guddiga hore ee caleenta hore wuxuu ka dhigi karaa hannaanka wadista gaariga, wuxuu ka hortagi karaa giraangiraha cirifka, dhoobada dusheeda salka gaadhiga, yaree waxyeelada jahwareerka iyo gogosha. Sidaa darteed, agabyada loo adeegsado waxaa looga baahan yahay in laga helo cimilada iska caabbinta iyo wax-daraaqaynta wanaagsan ee loo yaqaan 'Proved'. Dembiyada hore ee gawaarida badan ayaa laga sameeyaa shey caag ah oo leh dabacsanaan gaar ah, si ay u leedahay barkimo gaar ah oo aad u aamin badan tahay.
