Goobaha Codsiga ee ugu Muhiimsan
Warshadaha kabaha, EVA-geena waa qalab wax ka beddelaya ciyaarta. Waxay dib u qeexday fikradda raaxada iyo waarta kabaha. Isku-darka gaarka ah ee dabacsanaanta iyo sifooyinka nuugista shoogga ee EVA waxay ka dhigaysaa mid ku habboon kabaha cagaha. Hadday tahay kabaha fudud iyo kuwa boodboodka leh ee kabaha orodka ee bixiya dareen jawaab celin ah inta lagu jiro jimicsiga ama kabaha barkimada leh ee kabaha caadiga ah ee bixiya raaxada maalinta oo dhan, EVA-geena waxay bixisaa waayo-aragnimo aan la barbar dhigi karin. Soo-saareyaasha kabaha waxay ku tiirsan yihiin EVA-geena si ay u abuuraan alaab aan buuxin oo keliya laakiin ka badan filashooyinka macaamiisha marka loo eego raaxada iyo cimri dhererka.
Warshadaha baakadaha ayaa sidoo kale si weyn uga faa'iidaysta EVA-ga Caalamiga ah. Waxaa si weyn loogu isticmaalaa soo saarista agabka baakadaha ilaalinta leh. Saamaynta wanaagsan ee EVA - iska caabinta iyo awoodaha barkimooyinka ayaa ka dhigaya mid ku habboon ilaalinta alaabada jilicsan iyo kuwa qiimaha leh inta lagu jiro gaadiidka iyo kaydinta. Laga bilaabo qalabka elektaroonigga ah ee heerka sare ah sida taleefannada casriga ah iyo laptop-yada ilaa qalabka muraayadaha jilicsan iyo alaabada raaxada, baakadayada ku salaysan EVA waxay hubineysaa in waxa ku jira ay gaaraan meeshii loogu talagalay iyagoon waxba ka hadhin. Intaa waxaa dheer, awooddeeda lagu qaabeyn karo qaabab iyo cabbirro kala duwan waxay u oggolaanaysaa xalalka baakadaha ee la habeeyey, iyadoo la daboolayo baahiyaha gaarka ah ee alaabada kala duwan.
Warshadaha baabuurta, EVA waxay door muhiim ah ka ciyaartaa. Waxaa loo isticmaalaa qaybaha gudaha sida dashboard-ka, albaabada, iyo barkimooyinka kuraasta. Qaab-dhismeedka jilicsan ee EVA, buuqa - sifooyinka yaraynta, iyo iska caabbinta xirashada iyo jeexjeexa ayaa ka dhigaya doorasho ku habboon kor u qaadista raaxada iyo tayada khibradda wadista. Waxay sidoo kale gacan ka geysataa badbaadada guud ee gaariga iyadoo bixinaysa ilaalin nuugaysa saameynta haddii ay dhacdo shilal. Soosaarayaasha baabuurta waxay ku kalsoon yihiin EVA-dayada inay abuurto jawi raaxo leh oo ammaan ah oo loogu talagalay rakaabka.
Warshadaha ciyaaraha iyo madadaalada, EVA-gayaga waa agab muhiim ah. Waxaa loo isticmaalaa soo saarista qalab isboorti oo kala duwan, oo ay ku jiraan roogagga yoga, looxyada dabaasha, iyo qalabka ilaalinta. roogagga yoga ee laga sameeyay EVA-gayaga waxay bixiyaan dusha sare oo aan simbiriirixan lahayn, iyagoo hubinaya xasilloonida inta lagu jiro jimicsiga, iyagoo sidoo kale bixinaya saldhig raaxo leh oo barkimo leh. Looxyada dabaasha ee leh xudunta EVA waa kuwo fudud, dabacsan, oo waara, taasoo kor u qaadaysa waxqabadka kuwa dabaasha. Qalabka ilaalinta sida suufka jilibka iyo suufka xusulka ee laga sameeyay EVA waxay bixiyaan ilaalin saameyn oo la isku halleyn karo, iyagoo yareynaya khatarta dhaawacyada inta lagu jiro hawlaha isboortiga.
