Hata wewe ukienda fundishwa hizi turbo props ndogo, hilo swala la kuzimwa engine ni la kawaida sana
Hata wewe ukienda fundishwa hizi turbo props ndogo, hilo swala la kuzimwa engine ni la kawaida sanaJaribio la kifala sana alilifanya huyo rubani mpumbavu. Vipi Kama ingetokea ikagoma kuwaka!? Si ungekuwa msiba wa kujitakia huo!?
Twitter ukipost muda wote inasema sending, ikipata network inatuma, isipopata ndo imetoka hivoHuyu 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]
Sure, I have enjoyed your answer on the matter concerned, though I'm not the one brought the topic, but found myself interested on it. Thank you very much for your impressive answers. Now I have understood that the rudders come into operation automatically in a case if one of the twined engines fails. But steel I have one more question; for how long will the plane fly under the operation of a single engine before it lands for maintenance? Is there a time limit?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.
Ndege nyingi siku hizi zinaendeshwa na auto pilot, hii system ipo smart kuanzia monitoring hadi control,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.
Walio weka engine zaidi ya moja si wajinga, ni kulinda usalama. Mzungu kupiga kelele wakataharuki, ujinga, ushamba. Ndege za ingine moja ndio tatizo, na ni chache kutumika commercially.View attachment 2306678
Abiria ndani ya ndege ya Kampuni ya Precision, jana waliingiwa na hofu ya usalama wao baada ya injini moja kuzima ikiwa angani.
Ndege hiyo yenye namba PW 467 ikitokea Kahama, ikielekea Dar es Salaam kupitia Mwanza, ilizima injini baada ya dakika 51 kuruka kutoka uwanja wa ndege wa Mwanza.
Hofu ilianza kutokea baada ya abiria mmoja, kijana wa kizungu, kuanza kupiga kelele, akiwaeleza wenzake waliokuwa wameketi jirani, kwamba injini imezima.
Baadaye abiria wengine waliingiwa hofu, huku baadhi wakisali, wakilia na wengine kuonekana wamejiinamia, huku wamefunika nyuso zao.
Baada ya abiria kuonekana 'wakipaniki' ndipo rubani wa ndege hiyo alitangaza kuwepo kwa hitilafu hiyo huku akieleza kwamba hali siyo ya kutisha sana.
"Abiria wetu wapenzi, ndege yetu imepata tatizo la kiufundi, injini moja imezima, lakini hakuna haja ya kuwa na wasiwasi kwani, tunapanga kutua katika kiwanja jirani na hapa tulipo," alisema rubani huyo.
Hata hivyo, tulizo la mwana anga huyo halikuleta afueni ya wasiwasi kwa abiria wengi, waliendelea na hofu yao, huku wengine waliokuwa hawajatambua kinachoendelea wakiungana na wengine kusononeka.
Rubani alirejea tena kwa tangazo; "Abiria wetu wapendwa, tunasikitika kwa kilichotokea, nawaomba kuwa watulivu wakati sasa tunajiandaa kutua Uwanja wa Ndege wa Kimataifa wa Kilimanjaro. Tutatua ndani ya dakika 20."
Baada ya muda huo, ndege hiyo ilitua salama katika uwanja huo na abiria walishangilia. Wengine walipiga kofi, wengine wakipiga kelele za shangwe na wengine wakimshukuru Mungu.
Mmoja wa abiria aliyekuwamo ndani ya ndege hiyo, Simon Mkina, aliandika katika ukurasa wake wa Twitter na taarifa hiyo kusambaa dunia nzima, huku akipongezwa kwa kutoa taarifa hiyo mapema.
Bado ulikuwa sawa mkuu, "zero to none" ni english phrase. It is an informal way of saying, "absolutely NO possibility to happen".Haha kweli nimechapia !!!
Nilitaka kusema slim to none , hii ni american street language . Hata mie najifunza vingi humu humu , Jf ni kijiji kikubwa
Mkuu ndege huwa inakuwa designed,kuruka kwa engine moja au bila engine na rubani anafundishwa kurusha ndege kwa engine moja na bil engine.As long as engine moja imezima na hakuna physical damage yoyote uwezekano wa ndege kutua salama ni mkubwa kuliko gari kutokupata ajali likipata pancha ya tairi moja wakati likiwa na spidi sawa na ya ndege.Aiseee unaweza kufa kwa presha ukisikia hizo habari ukiwa juu huko
Daah! Madini Sana haya.
Maelezo yako yako sahihi lakini jua pia kuwa ndege inaweza tembea na engine moja pale nyingine ikizima na rubani ana uwezo wa kuibalance ndge mpaka itue salamaNdege 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.
Bado mnadanganywa kuwa ndege Zina maparachuti?

Kawaida sana hiyo. Ndege kuzima engine moja inatua vizuri tu bila shida na hata wakati wa kupaa huwa inatokea engine moja inazima zinapaa fresh tu.
Issue huwa inapotangazwa na pilot abiria ndani huwa wanapanic sababu ya kuhofia ajali za ndege ila huwa sio jambo la kutetemeka.
Ni procedure muhimu kwa pilot kuwajuza abiria kuwa wanafanya safe emergency landing sababu ya hitilafu ya engine.
Sawa Ndugu mdau kwa kuwa inakuwa Kati yangu Mimi ninayefundishwa na mfundishaji. Ila kuwafanyia majaribio abiria sio poa kwa kweli.Hata wewe ukienda fundishwa hizi turbo props ndogo, hilo swala la kuzimwa engine ni la kawaida sana
Thank you very much on this clarification. I believe it has been of interest and importance not only to me but also to other members of jf, as you may have observed the way they discuss the issue. May be they want to say something to thank you but are reluctant as many of us behave in, on behalf of them, once again I say thank you.Thanks a-lot for your compliment.
Well, the duration depends on the type of the aircraft, the manufacturers have put the time limit for every aircraft to fly with a single engine before landing. For example, the Boeing 787 Dreamliner has an ETOPS-330 certification, which means that, it can fly up-to 330 minutes (5.5 hours) with a single engine. The Boeing 787 Dreamliner could potentially fly longer than 330 minutes (5.5 hours) with a single engine, but it's not legally permitted to do so because of safety concerns.
Also, An aircraft specifically a passenger jet could glide for up to about 60 miles (about 96 kilometres), if it suffers a total engine failure at its cruising altitude (on average). Some aircrafts can glide even further. For example, a Boeing 747-200 can glide for 150 kilometres from a cruising altitude of 10,000 metres (33,000 ft).
NB: This can only be possible when all other electronics are working properly. But, If the electronics fails along with the engine, then my dear friend, YOU ARE GOING TO MEET YOUR CREATOR OR STRAIGHT TO HELL[emoji23][emoji23][emoji23]
Asante kwa elimuRelax wakuu, ndege hizi Zina engine mbili na engine moja ina uwezo wa kuifikisha ndege salama means to land safely, na hata engine zote zikizima pilot ana uwezo wa to land ndege as far as electronics ziwe zinafanya kazi(elewa kuna back up batteries zake).
Kudos kwa pilot wetu inajionyesha ni jinsi gani upo byeee na kwa abiria na wafanyakazi wote ambao mlitulia vema ndani ya ndege, ni MUHIMU mno kusikiliza yale maagizo yanayotolewa kabla ya safari kuhusu emergency.
Wengi wetu huwa we don't pay any attention kwa kufikiria it will not happen to us! Usafiri wa ndege ndio salama kuliko wote duniani.
Sorry mkuu nimechukua muda kukujibu nilikua sijaona hili, NO batteries hazisaidii ndege kuruka au kutua au to fly,zinasaidia electronics ziwe on,na zikiwa on zinasaidia kufanya Ile emergency landing, hivyo hivyo kwa Q2.Hizi modern aircrafts zimeundwa kuwa hata kama engine zote zinafail zina weza to glide kwa ratio nzuri tu yaani 1:10,means inaweza kusafiri umbali wa zaidi ya 10,000feet ,na glide hii itatoa nafasi kwa pilot kuangalia au kufikia next airport, na elewa hizi ndege zinafuata njia maalum ambazo viwanja vya kutua kwa dharura havipo mbali, mfano kutoka Nairobi Airport to Jhb Airport, ndege itakuja na straight line yaani thr kilimanjaro Airport, parts of Dodoma na Iringa, then Ruvuma na zita cross kuingia malawi means lilongwe haitakua mbali na ziwa nyasa, then itaingia parts of Zimbabwe (Harare ipo jirani),straight into limpopo province in SA na mwisho wake joberg, route hii inapita kwenye viwanja vingi tu vya ndege in case of emergencyAsante kwa kutuelimisha; naomba kujua
1. Engine zikizima zote, ndege hizi za kawaida Abiria 45 to 170 hivi inaweza kutembea umbali gani kwa battery?
2. Hivi vindege vidogo vya hapa nyumbani - Caravan (C208) na Pilatus (PC12) karibia zote zina Engine moja; Je nazo zina backup battery? Je hiyo engine ikizimika battery yake inaweza kwenda umbali gani?
HII SIO KWELI KABISA!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..
nimekuelewa asante,Sorry mkuu nimechukua muda kukujibu nilikua sijaona hili, NO batteries hazisaidii ndege kuruka au kutua au to fly,zinasaidia electronics ziwe on,na zikiwa on zinasaidia kufanya Ile emergency landing, hivyo hivyo kwa Q2.Hizi modern aircrafts zimeundwa kuwa hata kama engine zote zinafail zina weza to glide kwa ratio nzuri tu yaani 1:10,means inaweza kusafiri umbali wa zaidi ya 10,000feet ,na glide hii itatoa nafasi kwa pilot kuangalia au kufikia next airport, na elewa hizi ndege zinafuata njia maalum ambazo viwanja vya kutua kwa dharura havipo mbali, mfano kutoka Nairobi Airport to Jhb Airport, ndege itakuja na straight line yaani thr kilimanjaro Airport, parts of Dodoma na Iringa, then Ruvuma na zita cross kuingia malawi means lilongwe haitakua mbali na ziwa nyasa, then itaingia parts of Zimbabwe (Harare ipo jirani),straight into limpopo province in SA na mwisho wake joberg, route hii inapita kwenye viwanja vingi tu vya ndege in case of emergency
