true modern planes do have even more power but the wings are designed to be powered if a modern jet loses all power there is not much glide involved in it. the engines (@ least one of them must be on ) to even glide.
@circusboy90210 modern jet aircraft can glide pretty well actually in fact there has being a couple of instances were a modern airliner had lost all engine power and glided a long way to a safe landing "the wings are designed to be powered" the fundamental design principles haven't changed
@circusboy90210 yes I study engineering at university trust me a jet will not just drop from the sky after losing power a wing will generate lift as long as it is above a certain speed without power the speed can be kept within the limits by dropping the nose trade of height for speed a certain ratio of altitude is lost for a certain amount of distance traveled all aircraft have an optimal glide rate that will get it the most distance try google gimili glider
@hod05 mitigating factors, not all apu will or cn start in flight loss of flight controls ensues, hence you cannot drop the nose. dropping the nose increases the rate of descent & speed towards terra firma. also ges turbines not powered add additional drag further more taking away from speed & causing drop increases. ture I"im an arm chair captin , but I do also have thousands of hours in other heavy vehicles, so my perspective of self preservation enhances my perception of certain things.
@circusboy90210 jets have deployable ram air turbines to generate power for flight controls and critical systems the nose would only be dropped slightly the descent would be fairly slow typical rates if i remember correctly can be around 20 miles for every 1000ft lost so from a typical cruise altitude of 30,000 thats still a fair distance like i said the basic principals of flight have not changed since the times of piston engine aircraft
@hod05 you have not stated your specific variant of discipline. however the historic perspective & what pilots have been mentioning is that that is a theroetical slope reality is that this is incorrect. would make sense to have deployable ram air turbines but no one has ever mentioed the existance of this mythical device. a triangle will alwasy be he strongest but jet & prop planes do not have similar wing chords per their same weight.
@circusboy90210 neither have u however Im doing a BEng in engineering drafting thats basically the guy that takes the data and puts the blueprints/plans together to do this you need to have certain mechanical knowledge and theory. anyway in reality there has being at least 2 cases of airliner gliding 100+miles to a safe landing and even 1 were engines were restarted in flight 15min after they all flamed out after ingesting ash "mythical device"?
@hod05 yeah rat's are very usefull to drop just testing you. took drafting in junior high myself, not justifiable as a copmlete course, try doing that in your head without cad cam. .
@circusboy90210 u may have done a basic course at school yes but to become a drafter a degree level qualification is needed with all the ISO standards and conventions rules and regulations and precision its similar to architecture it certainly justifiable we do a lot of exploded and assembly diagrams alot of our modules r on engineering theory,maths,inspecting components/assemblies ect and hands on manufacturing besides we did learn to draft traditionally without CAD before using it.
@hod05 teachers inmy schoool went over more than the basaics with us, was very adamant about learning as much as possible, picked his brain clean learned & performed most the above. saw alot of this being done before tooo . definatly a skill that needs to be preserved ofr situations when there is anot a computer availabl. humans can do a better job sometimes on a one by one basis, machines have seed. thiats it.
@circusboy90210 well ul agree that doing an isometric exploded assembly diagram of a gas turbine 4 example with all the sub assemblies and parts in assembly order, labelled, drawn to scale to ISO stnd and precise plotted on a drawing board not only needs the skill but ideally at the very least a basic understanding of the principles and manufacture of the machine itself basically drafter is to a machine wot an architect is to a building
@hod05 admiralable your studiese to impoorve your skill set are. but no you only need to be able to draw very accuratly & put thinngs into proper perspective, knowledge of how it's goiing to be manufactured or how it functions have nothing to do with accuratly portratying the unit. a drafter is someone who puts things on paper from techincal specs nothing more he/she is not a crator of anytinng just merely a tool. an engineer is to a machine as a chef is to culinary arts .
@circusboy90210 i never said we create anything u r correct an engineer crunches the numbers we the interpret data and put it into plans that others use to assemble/repair however that is what most architects do they take data from structural engineers/surveyors and put it into plans several graduates from my course have successfully gone into this field some starting as drafter ended up doing various other jobs within engineering so its gud to have a general knowledge
@hod05 no offense their is no "we "yet your still in school. general knowledge is good but a drafsman creates nothing. I do wish you the best of luck in whatever endeaver you proced to do though.
@circusboy90210 none taken im currently on a contracted 4month work placement working with qualified drafters so... i never said drafters create anything not sure why u keep bringing that up an education in engineering and maths are desired if not required by most employers (i tried after collage everyone wanted a degree) my other point being u rarely get a job for life today most jobs can lead onto something else it pays to be flexible these days
@hod05 my first degree did not pan out for me. no job no experience , no experience no job. my plan is to educate myself & manipulate materials into a fashion I see fit to maximize my design parameters & have fun. don't need sheepskin to do your own thing plus the job is for life.
@circusboy90210 I do see what u are saying regarding the whole no experience no job catch 22 thing. just out of interest what field of engineering are you in u said in an earlier post u have thousands of hours driving heavy vehicles what vehicles do u drive?
@hod05 mostly liimousines of all type from 7& 9 pax stretch to 12 pax superstretch, 24 pax hummers & escalades to 42 pax escalade & party busses. 15 pax mini bus & 52 pax full size busses. my ice cream truck was 12k gvwr. 18 wheelers in commodoty trades & furniture moving, along with my own step ven 12 gvwr, and many different delivery trucks 17 & 24 straight trucks.
study mostly aerospace engineering & high tech materials, civil & mechanical, automotive, naval engineering to mysterious.
Funny that Freakybuzz wrote a sensible comment two years ago, whereas most of the recent comments are full of misspellings, not written in sentences and pretty incomprehensible.
@circusboy90210 just type in ram air turbine deployment on utube theres a few vids showing the RAT as its sometimes called its by no means a mythical device
I'm willing to bet there are a lot of things they are not showing in this video. The pilots probably have the rudder trim full right to counteract the off axis thrust of the remaining outboard engine.
@111olbap really is that why far state that they be deisgned to do so????? that's probably one of the main advatantage os multi engine setups, please think before you speak.
Long before the oil runs out, the socialists in power now will regulate our general aviation industry to death, ridding this country once and for all of the last little bit of Americana we had remaining. They are already at it, trying to turn our small airports into ghost towns.
so the plane doesnt just drop from the sky when engine failure occurs..ok i feel a little better but its still odd.. wud it not crash in the end when they try to land? i wonder when a 747 is gliding on its on, do the passengers feel like hey are falling.. (yes iv a ginormous fear of flying how did u tell lol)
Even if an aircraft lost all engines, the passengers would feel no sensation of falling any more than in a normal, powered descent as the plane would become at that point a glider.
EVERY pilot receives training on how to land an airplane without engine power; I've done so myself on several occasions-- just for training fortunately. From small Cessnas to large Boeings, the basic aerodynamic principles are the same.
wow that made me feel loads better :)thank god i just had this huge fear of plummeting at any minute at 30,000 ft im hysterical when ever i have to fly lol sounds stupid but i just dont understand enough about planes to trust them. but thanks a mill for that helpfull and extremely reassuring info !!
Glad to hear it. :-) Flying is still the safest way to travel, and the level of pilot training and aircraft maintenance received in North America and Europe is second to none. Google "Ask the Pilot" for flying information from a veteran airline pilot with great answers to many common questions.
Just think of the air becoming "thick" like jello when taking off at high speed. The plane is designed to decend naturally and can glide approximately 100 miles in the extremely unlikely event of all engines failing.
oh yes i think i heard of the air bocoming like a pillow on which the plane is travelling over or something! thats great! so i was freakin out on all my flights for nothing LOL, thanks!
Like all internal-combustion vehicles, the power isn't needed to keep going, but to GET going. While your common V-8 in a pickup truck makes around 350 HP, you only need about 20-30 HP to fly down the highway. Same for planes. That's why power loss (engine failure) on take-off is so often deadly.
imagine IF it happened with the flaps full and gear down at landing speed
