Kwa ufupi dogo aliona pangaboi limeacha kuzunguka
Kwa ufupi dogo aliona pangaboi limeacha kuzungukaMuungurumo wa ndege huwa mwepesi zaidi! Halafu ndege inakuwa kama inaelea elea hivi angani
Sasa zikizima, what will be the dragging force to push the plane forward? Kumbuka usalama wa ndege ikiwa angani ni mwendo wake.Injini za ndege sio kama za bajaj. Kila injini inajitegemea kuanzia mifumo hadi utendaji.na Kila injini inao uwezo wa kuhakikisha ndege inatua salama hata kama zote zimezima
Hiyo rudder inaoperate automatically baada ya engine kuzima au anaoperate pilot? Na kama inakuwa operated na pilot, nini kinatokea toka engine inazima mpaka pilot anaoperate hiyo rudder? Maana kutakuwa na time lapse.Mimi sio expert wa aviation ila nafahamu mawili matatu kuhusiana na ndege. Kiufupi ndege ya engine mbili ni lazima kwa mujibu wa Etops standards iweze kusafiri angani ikiwa na engine moja kwa zaidi ya dakika 60.
Hiyo ya kuvuta upande mmoja umekariri , kuna namna rudder kule nyuma amabayo ndiyo usukani wa ndege , rudder ndiyo inacompesate balance ya ndege hata kama thrust inatokea upande mmoja wa engine.
Ndege za engine tatu trijets kwa sasa hazipo tena kwenye biashara ya abiria , hizi ni mc donnel md 10 md 11 , pamoja na loockheed L 1011, The last mc donnel md 11 , nafikiri ilikuwa operated na KLM na hapa Tanzania ilikuwa inatua pia . Trijets zipo kwenhe biashara ya mizigo , hata Fedex md10 huwa inatua Dar.
Moja kati ya ajali chache za ndege zilizorekodiwa live hadi ndege inaanguja, wale watalii walikuwa na mikamera pale ufukweniYes mkuu, binafsi ninafuatilia sana kuhusu vipindi vya Air crash investigation, yule pilot wa Ethiopian Airways alirudi kazini na kuendelea to fly, was sad kwa yule journalist ambaye alipoteza maisha, na wale vijana walioteka Ile ndege hawakuwa kabisa na ABC kuhusu ndege ilivyo na systems zake, kuna tetesi kuwa pilot aliomba atue pale Dar es Salaam int. Airport akanyimwa kibali (but hii ni debate for another time).
Mkuu huwa unaangalia vile vipindi vya ajali za ndege youtube? Mbona kule tunaona ndege ina uwezo wa kutembea na injini moja hata kama ziko kwenye mabawa?Ndege inayoweza kwenda na engine moja ni ile tu ambayo engine yake imefungwa katikati, kwa maana ya kuigawa hiyo ndege symmetrically. Na ndio maana ndege za engine moja (hasa ndege ndogo), engine hiyo imefungwa katikati mbele. Vinginevyo ingefungwa anywhere lakini katikati ili kuigaga into two halves. Huwezi kupata configuration nyingine.
Kwahiyo mkuu simu ndo yake ndo ilikuwa chanzo cha kuzima engine moja....Kwanini alitumia simu chombo kikiwa angani wakati huwa inakatazwa?

Sio kwamba hata zile zingine nazo pia Zina pangaboi ila haliko uchi "yaani limefichwa".Hizi ndege za precision engine zake ni za pangaboy so ukikaa siti ya dirishani usawa wa bawa la ndege ukichungulia unaiona ikizunguka...
Jaribio la kifala sana alilifanya huyo rubani mpumbavu. Vipi Kama ingetokea ikagoma kuwaka!? Si ungekuwa msiba wa kujitakia huo!?Mkuu kuna pilots wengine ni wajinga hasa.... kuna moja wa hizi ndege ndogo za injini moja tulikuwa tupo wasela watupu tunatoka nairobi kwenda KIA sasa katika kupiga story tukaanza kubishana kama ndege inaweza kwenda ikiwa imezimwa injini sasa katika kutupa ile assurance kwamba hilo linawezekana aliamua kuzima engine ndege ikiwa angani kabisa kwa dakika moja hivi kisha kaiwasha tena..
Inategemea na ETOPS rating yake. Ndege tofauti zina rating tofauti.Muda gani inaweza kuruka na engine moja?
Ndege za Taifa hizo, tungeweka mapovu ya kutosha mkuu, moja ya sababu ya ATCL kukosa soko ilikuwa hilo yaani ikipatwa na delay au shida ya kiufundi ilikuwa lazima ukurasa wa mbele wa gazeti ukutane na habari nzito huku kampuni zingine zikiwa na matatizo yanayoambatana na hayo wala husikii (hii nazungumzia kabla ya kuja ndege hizi mpya)mwana JF hebu waza huu uzi ungekuwa unahusu ATCL wachangiaji wangekuwa wanasemaje?
Pamoja na id feki zetu ila members wa jf ni "walewale"
Siku hizi simu nyingi ama zote zina "aircraft mode" na naona wanaruhusu kuweka kwenye "aircraft mode off" simu hivyo kuna wapuuzi wanaamua kutozima kabisa. Zamani wakisema zima simu unatakiwa uzime simu hata kama ukiweka kwenye "aircraft mode", mhudumu akikuona wakati anahakiki kama mambo yapo sawa wakati kitu ndio kinataka kuchukua kasi yaani anaweza kukumeza hata kama utamwonyesha umeweka off kwenye aircraft mode.Huyu aliyewasha simu aka-tweet ni wa kushtaki kabisa---angeweza kuingilia intercoms na kusababisha majanga zaidi,
Ndegenyingi commercial zina backup plan---as long engine haijafeli wakati hajaweka ndege sawa(levelling Off)--pia ifahamike kuwa inaweza kuzimwa--ama inaonyesha mashaka(au ndege kaingia kwa jet engines) au kuzimika yenyewe.
Ni jambo la kawaida---na hata ndege ikiwa kwenye auto-pilot huwezi kugundua kirahisi.
Mimi ninamwaza sana huyu aliye tweet---sawa watu wangefahamu---lakini yeye itamsaidia nini?
Nonsense!
Which means at the time watu wanasoma, kitu ndio kinautafuta ule mstari mweupe katikati ya uwanja kwa mbaliiiiiiiiii kikiwa taratibu kinashuka na watu wanaanza ku-respond kitu tayari kimetuaHuyu mtu aliyepost hajui kuwa minara ya siju haishiki angani?
Maana yake post yake imekuwa sent baada ya wao kukaribia kabisa KIA ndio ikakamata network na kupost, kitu bacho hakisaidii[emoji1787]
Daah! Madini Sana haya.Q.) Will an airplane with one-sided engine, turn to either side?
The answer is definitely YES. Flying with one engine on a multi-engined airplane, will cause it to yaw to side of the dead engine. This is due to the Asymmetrical Thrust thus created.
How does a pilot deal with it?
The airplane will tend to turn towards the side of the dead engine. Now what the pilot has to do is that use the rudder and ailerons to counteract with the yaw. The rudder and ailerons has to be trimmed accordingly, to deal with it.
Trimming is needed as it would be stressful for the pilot to continuously hold the controls till the airplane is safely landed.
Q.) Can the airplane maintain the cruise altitude?
Nope. An airplane can't maintain its cruise altitude due to less thrust available and the asymmetrical thrust. Therefore, in such a situation the pilot descends the airplane to the “single engine service ceiling ”.
It is the maximum altitude, where a pilot should be allowed to fly if a single engine is working.
For example, the Airbus A330 can safely cruise at 36000-38000 feet with all enginesworking. But if it looses one engine, then the airplane descends to its Single engine Service Ceiling of 33000ft or lower.
Hope that you enjoyed the answer.
Kuna watu wana madini humu acha tu, sema ID zetu fake hizi zinafanya watu wengine kuwachukulia poa...kuna mwamba anaitwa barafu alikuwa anatoa sana madini haya ya ndege sijui yuko wapi aje akazie kidogoDaah! Madini Sana haya.
Maswali mengi niliyouliza nayajua majibu yake nimeuliza tu maana naona mtu anakueleza kitu anachokijua juu juu.Inategemea na ETOPS rating yake. Ndege tofauti zina rating tofauti.
ETOPS - Extended-Range Twin-Engine Operations Performance Standards
Mfano kuna ndege ni ETOPS-180: Hii inaruhusiwa kutembea 180 minutes with one engine failed, na imeshakuwa tested for that at full load. (Impact yake kisheria ni kwamba wakati wote ndege ipo angani inatakiwa iwe 180 minutes away from a suitable landing airport- hata kama route itakuwa ndefu). Such na 120,330,370 etc
Failure au fire ya engine moja kwenye ndege hizi ni non-event.
Ishu ni failure of control surfaces mzee. Zile ailerons, rudders, flaps au spoilers zikistuck ndio rubani anatokws jasho na abiria mtatoka uharo
Haya madini Aisee! Nimejaribu ku_google baadhi ya vitu Kama hiyo Etops . Aisee Hawa jamaa almost wanajua kila kitu kuhusu haya mandege. Inaonekana kila scenario unayoiwaza wao walishakuwa na namna ya ku_deal nayo.Mimi sio expert wa aviation ila nafahamu mawili matatu kuhusiana na ndege. Kiufupi ndege ya engine mbili ni lazima kwa mujibu wa Etops standards iweze kusafiri angani ikiwa na engine moja kwa zaidi ya dakika 60.
Hiyo ya kuvuta upande mmoja umekariri , kuna namna rudder kule nyuma amabayo ndiyo usukani wa ndege , rudder ndiyo inacompesate balance ya ndege hata kama thrust inatokea upande mmoja wa engine.
Ndege za engine tatu trijets kwa sasa hazipo tena kwenye biashara ya abiria , hizi ni mc donnel md 10 md 11 , pamoja na loockheed L 1011, The last mc donnel md 11 , nafikiri ilikuwa operated na KLM na hapa Tanzania ilikuwa inatua pia . Trijets zipo kwenhe biashara ya mizigo , hata Fedex md10 huwa inatua Dar.
Yes hata kwenye training huwa zinazimwa kweli na instructor uwapo angani, afu anaiwasha baada ya mudaMkuu kuna pilots wengine ni wajinga hasa.... kuna moja wa hizi ndege ndogo za injini moja tulikuwa tupo wasela watupu tunatoka nairobi kwenda KIA sasa katika kupiga story tukaanza kubishana kama ndege inaweza kwenda ikiwa imezimwa injini sasa katika kutupa ile assurance kwamba hilo linawezekana aliamua kuzima engine ndege ikiwa angani kabisa kwa dakika moja hivi kisha kaiwasha tena..
