Isingeniso se-Indicated Airspeed
Lapho eqala uhambo lokuqonda izinsimbi zendiza, umuntu kufanele aqale abone indima ebalulekile edlalwa i-airspeed ekhonjiwe (IAS). Kuyipharamitha eyisisekelo ku-cockpit, ekhonjiswa ngokugqamile ku- inkomba yesivinini somoya. Lesi sinyathelo esibalulekile akusona nje inombolo kodwa ucezu olubalulekile lolwazi olusetshenziswa abashayeli bezindiza ukuze baqinisekise ukuthi indiza isebenza ngaphakathi kwemikhawulo yokusebenza ephephile.
Ingqikithi yesivinini somoya esibonisiwe idlulela ngale kwenani layo lenombolo; imele umfutho oguquguqukayo odalwa ukunyakaza kwendiza, okubonakala njengesivinini somoya yithuluzi. Lokhu kucindezela okuguquguqukayo kuyisisekelo sokuhamba kwendiza, okunomthelela ekuphakameni, ukuhudula, kanye nokusebenza kukonke. Amaflaya aqalayo kanye nama-aviator angomakad' ebona kufanele babambe ama-nuances we-IAS ukuze baqonde esibhakabhakeni.
Ukuqonda umqondo we-airspeed ekhonjiwe kudinga ukuhlolisisa i-physics yendiza. Izinkomba zejubane lomoya zikala umehluko wengcindezi phakathi komoya omile ozungeze indiza kanye nengcindezi eguquguqukayo ekusakazeni komoya wendiza. Lo mehluko yilokho abashayeli bezindiza abakubona njengesivinini esibonisiwe. Kuyisixhumanisi esiqondile samandla okusebenza kwendiza ezindaweni eziphakeme nezimo ezihlukahlukene.
Ukuqonda Izisekelo Zejubane Elibonisiwe
I-airspeed ekhonjiwe ihlanganisa abashayeli bezindiza bedatha eluhlaza abaqala ukuyibona kumathuluzi abo. Kuyijubane lendiza njengoba likalwa yi- isistimu ye-pitot-static, ehlanganisa kokubili ishubhu le-pitot lokulinganisa ingcindezi eguquguqukayo nezimbobo ezimile zokulinganisa ukucindezela komkhathi okuzungezile. Isibonisi sesivinini somoya sibe sesisebenzisa lezi zilinganiso ukuze sibonise i-IAS.
Lesi silinganiso asibali izinguquko zokuminyana komoya noma izinga lokushisa. Ukwehluka okunjalo kungashintsha kakhulu izici zokusebenza zangempela zendiza. Ngakho-ke, nakuba i-IAS iyisilinganiso esiqondile esitholakala kumshayeli wendiza, ayikona ukumelwa okuphelele kwesivinini sendiza phezu komhlaba noma imvilophu yokusebenza kwayo.
Ukusebenzisana phakathi kwesikhombisi se-airspeed kanye nesistimu ye-pitot-static kugcizelela ukubaluleka kokuqonda imikhawulo yethuluzi. Ukuvinjwa ohlelweni noma amaphutha ensimbi kungaholela ekufundweni okungalungile. Ngakho, abashayeli bezindiza kufanele baqeqeshwe ukuze babone lokho kungafani futhi bazi ukuthi kufanele baphendule kanjani ukuze baqinisekise ukuphepha endizeni.
Ukubaluleka Kwe-Airspeed Ekhonjisiwe Kwezokundiza
Isivinini somoya esibonisiwe akuyona nje inombolo esesilinganisweni; kuwumgogodla wemikhuba ephephile yokundiza. Kwezokundiza, ukuphatha isivinini sezindiza kubalulekile ekugcineni ukulawula kwendiza. I-IAS inikeza ireferensi enokwethenjelwa kubashayeli bezindiza ukuze basebenzise ukuqondisa okubalulekile, kusukela ekusukeni kuya ekufikeni kokufika. Yijubane abashayeli bamabhanoyi abahlela ngalo ukusebenza kwendiza, benza izinqumo zokuthi kufanele bakhuphuke nini, behle nini, nokuthi kufanele balungise nini indlela abasondela ngayo kumzila wezindiza.
Ngaphezu kwalokho, i-IAS isetshenziselwa ukunamathela emithethweni yokulawula ukuhamba kwezindiza kanye nokuqinisekisa ukuthi indiza ihlala ngaphakathi kwemingcele yesakhiwo sayo. Indiza ngayinye inejubane elithile elaziwa ngokuthi ama-V-speeds, anqunywa i-IAS. Lokhu kufaka phakathi isivinini sokusebenza okuphephile, njenge-Vr yokuzungezisa kanye ne-Vne yokungalokothi yeqe isivinini, okubalulekile ekuvimbeleni ukwehluleka kwesakhiwo endizeni.
Ukubaluleka kwe-IAS kudlulela endimeni yayo yokuqinisekisa ukusebenza kahle kwendiza. Ivumela ukuthuthukiswa kokusetshenziswa kukaphethiloli ngokuvumela abashayeli bezindiza ukuthi bandize ngesivinini esinciphisa ukudonsa nokukhulisa ukuphakama. Mayelana nalokhu, i-IAS isebenza njengepharamitha eqondisayo kubashayeli bezindiza ukuze bazulazule uxhaxha lwezimo zendiza, ikwenze kubaluleke kakhulu embonini yezokundiza.
Ungabala kanjani i-Airspeed ebonisiwe

Ukubala kuqala ngohlelo lwe-pitot-static oluthwebula umfutho oguquguqukayo womoya oshayisana nendiza njengoba iya phambili.
Lokhu kucindezela okuguquguqukayo bese kuqhathaniswa nokucindezela komkhathi okuzungezile kukalwa ngezimbobo ezimile. Isikhombi sesivinini somoya, isisetshenziswa esiwumshini noma se-elekthronikhi, sihumusha lo mehluko wengcindezi futhi siwuguqulele ekufundeni kwesivinini, okuboniswa njenge-IAS. Le nqubo, nakuba ibonakala iqondile, ihlanganisa ukulinganisa okuyinkimbinkimbi nokulungiswa ngaphakathi kwethuluzi ukuze kuqinisekiswe ukunemba.
Ezimeni lapho inkomba yesivinini somoya singasebenzi kahle, abashayeli bezindiza bangasebenzisa izindlela zokulondoloza ukuze balinganisele i-IAS yabo. Lezi zindlela zingase zibandakanye izibalo ezisekelwe kudatha ye-GPS, isivinini esiphansi, isivinini somoya, nendlela, nakuba zinganembile njengokufundwa okuqondile kwe-IAS kusukela ekusebenzeni. isistimu ye-pitot-static.
Inqubo yokubala i-IAS imisiwe, kodwa kubalulekile ukuqaphela ukuthi ukunemba kokufunda kungathonywa izici ezimbalwa. Lokhu kufaka phakathi iphutha lensimbi, ukungafani kokufakwa, kanye nesimo sesistimu ye-pitot-static. Ukugcinwa okuvamile nokulinganisa kubalulekile ukuze kuqinisekiswe ukuthi ukubala kwesivinini somoya okubonisiwe kuhlala kuthembekile.
Izici Ezithinta I-Airspeed Ekhonjisiwe
Nakuba isivinini somoya esibonisiwe sinikeza inkomba ebalulekile kubashayeli bezindiza, sithonywa inqwaba yezinto ezingashintsha ukunemba kwayo. Esinye salezo zici ukuminyana komoya, okushintsha ngokuphakama, izinga lokushisa nomfutho womkhathi. Njengoba indiza ikhuphuka, ukuminyana komoya kuyehla, okuholela ekuphambeni phakathi kwe-IAS nokusebenza kweqiniso kwendiza.
Ukwehluka kwezinga lokushisa nakho kudlala indima ekuthinteni ukufundwa kwe-IAS. Umoya obandayo uminyene kunomoya ofudumele, okusho ukuthi ku-IAS efanayo, indiza izobe ihamba ngokushesha ezimeni ezibandayo uma kuqhathaniswa nezimo ezifudumele. Lokhu kungaba nomthelela endleleni abashayeli bezindiza ababona ngayo isivinini sabo somoya futhi kungase kudinge ukulungiswa ukuze kugcinwe ukusebenza abakufunayo.
Esinye isici ukunemba kwesikhombi se-airspeed ngokwayo. Iphutha lamathuluzi lingavela ezinkingeni zokulinganisa, ukuguga nokudabuka, noma ukulimala kwesistimu ye-pitot-static. Ukugcinwa njalo kanye amasheke ngaphambi kokundiza zibalulekile ekuhlonzeni nasekusingatheni lezi zinkinga ukuze kuqinisekiswe ukufundwa kwe-IAS kuhlala kuwumthombo onokwethenjelwa wolwazi lwabashayeli bezindiza.
I-Airspeed Ekhonjisiwe iqhathaniswa ne-True Airspeed
Ukwehlukanisa phakathi i-airspeed ebonisiwe kanye ne-airspeed yeqiniso (TAS) kubalulekile ukuze abashayeli bezindiza bahambe ngendlela efanele. Isivinini somoya sangempela silandisa ngokuhlukahluka kokuminyana komoya kanye nezinga lokushisa i-IAS engakwenzi. I-TAS isivinini sangempela indiza ehamba ngaso emoyeni futhi ibalulekile ekuhleleni indiza nokuzulazula.
Ukuze uguqule i-IAS ibe yi-TAS, abashayeli bezindiza kufanele balinganisele ekuminyaneni komoya endaweni yabo yokuphakama kanye nezinga lokushisa lamanje. Lokhu kulungiswa kuvame ukufezwa kusetshenziswa ikhompuyutha yendiza noma izinhlelo ze-flight bag (EFB) ezenza ukuguqulwa ngokuzenzakalela ngokucabangela okuguquguqukayo okufanelekile.
Ukuqonda umehluko phakathi kwe-IAS ne-TAS kubalulekile futhi ekuxhumaneni nokulawulwa kwethrafikhi yomoya kanye nokugcina amazinga okuhlukanisa endaweni yomoya elawulwayo. Abashayeli bezindiza kufanele babe nobuchule bokuhumusha isivinini sobabili ukuze baqinisekise ukusebenza kwendiza okuphephile nokusebenza kahle, ikakhulukazi uma undiza ezindaweni eziphakeme lapho umehluko phakathi kwe-IAS ne-TAS ungaba obalulekile.
Umthelela Wesivinini Somoya Esibonisiwe Ekusebenzeni Kwendiza

Kuyisisekelo lapho abashayeli bezindiza besekela khona izinqumo zabo mayelana nokuphakama, izilungiselelo zamandla, nokumiswa kwendiza. I-IAS inomthelela ngokuqondile ekuphakameni okukhiqizwa amaphiko, okubalulekile ekugcineni ukundiza.
Uma i-IAS iphansi kakhulu, indiza isengozini yokuma ngenxa yokungakhuphuki okwanele. Ngokuphambene, uma i-IAS iphezulu kakhulu, indiza ingase ibe nengcindezi engadingekile ku-airframe yayo, okungase kuholele ekuhlulekeni kwesakhiwo. Ngakho-ke, abashayeli bezindiza kufanele bahlale beqaphile mayelana nesivinini sabo somoya ukuze bagcine indiza ingaphakathi kwemvilophu yokusebenza ephephile.
Iqhaza le-IAS lidlulela ekusukeni kwendiza nokusebenza kokuhlala phansi. Abashayeli bezindiza bathembele ekufundweni kwe-IAS ukuze banqume ukuthi bazungezisa nini phakathi nokusuka kanye nokuqinisekisa ukuthi indiza ifika phansi ngesivinini esiphephile ngesikhathi sokuhlala. Lezi zigaba ezibalulekile zendiza zigcizelela ukubaluleka kokufundwa kwe-IAS okunembile kukho konke ukuphepha kwendiza.
Imibono Engalungile Evamile mayelana Ne-Airspeed Ekhonjisiwe
Kunemibono eminingana eyiphutha mayelana nesivinini esikhonjiwe esingaholela ekudidekeni phakathi kwabashayeli bezindiza nabathandi bezindiza. Okunye ukungaqondi okuvamile ukuthi i-IAS imele isivinini sendiza ngokuhlobene naphansi. Eqinisweni, i-IAS ibonisa ingcindezi eguquguqukayo futhi ayibonisi ngokuqondile isivinini esingaphansi komhlaba, esingaphazanyiswa umoya nezinye izici.
Omunye umbono oyiphutha inkolelo yokuthi i-IAS ihlala injalo kungakhathaliseki ukuthi ikuphi ukuphakama. Nakuba i-IAS ibonisa isivinini somoya njengoba silinganiswa isistimu ye-pitot-static, ayibali izinguquko ekuminyaneni komoya ezindaweni eziphakeme ezihlukene, ezingathinta ukusebenza kwangempela kwendiza.
Okokugcina, abanye bangase bacabange ukuthi i-IAS ephakeme ihlala ilingana nendiza esheshayo. Kodwa-ke, i-IAS kufanele iqondwe ngokomongo nezinye izilinganiso zesivinini somoya, njenge-TAS nesivinini esiphansi, ukwazisa ngokugcwele ukusebenza kwendiza. Kubalulekile ukususa le mibono eyiphutha ukuze kuthuthukiswe ukuqonda okungcono kwe-airspeed dynamics.
Intuthuko ku-Indicated Airspeed Technology
Indawo yobuchwepheshe be-airspeed ebonisiwe ibone intuthuko enkulu phakathi neminyaka. Ukuqamba okusha kuma-avionics edijithali kuholele ezinkomba ezinembile nezithembekile zesivinini somoya. Imibukiso yesimanje yengilazi ye-cockpit ihlanganisa ulwazi lwesivinini somoya nenye idatha yendiza, ihlinzeka abashayeli bezindiza umbono obanzi wesimo sendiza.
Ukwengeza, ama-smart probe namakhompyutha edatha yomoya aguqule indlela isivinini esikalwa ngayo. Lawa masistimu anikeza ukunemba okuthuthukisiwe futhi anganxephezela amanye amaphutha atholakala kumasistimu omdabu we-pitot-static. Ukuhlanganiswa kwalobu buchwepheshe obuthuthukisiwe ezindaweni zokuhlala kuthuthukise ukuphepha nokusebenza kahle kwendiza.
Ucwaningo luyaqhubeka nokwenza izinhlelo zokulinganisa isivinini somoya eziyinkimbinkimbi nakakhulu, okuhlanganisa nalezo ezikwazi ukubona futhi zinxephezele izimo zokuqhwaza eshubhu le-pitot. Ikusasa lobuchwepheshe bejubane lomoya elibonisiwe lithembisa ukuhlinzeka abashayeli bezindiza ngamathuluzi anganembe kakhudlwana kuphela kodwa futhi akwazi ukumelana nezimo eziyinselele okuhlangatshezwane nazo endizeni.
Isiphetho
Ukuzulazula esibhakabhakeni ngokuphephile nangempumelelo kuncike ekuqondeni komshayeli wendiza nokusetshenziswa kwesivinini esibonisiwe.
