Fly-by-wire!!!!

Mechanical and hydraulic flight control systems are heavy and require careful routing of flight control cables through the airplane using systems of pulley and cranks. Both systems often require redundant backup, which further increases weight. Furthermore, both have limited ability to compensate for changing aerodynamic conditions.

By using computers and electrical linkages, designers can save weight and improve reliability. Electronic fly-by-wire systems can respond more flexibly to changing aerodynamic conditions, by tailoring flight control surface movements so that airplane response to control inputs is consistent for all flight conditions. Electronic systems require less maintenance, whereas mechanical and hydraulic systems require lubrication, tension adjustments, leak checks, fluid changes, etc. Furthermore putting circuitry between pilot and aircraft can enhance safety; for example the control system can prevent a stall, or can stop the pilot from overstressing the airframe.

Most fly-by-wire systems incorporated redundant computers and some kind of mechanical or hydraulic backup. This may seem to negate some advantages of fly-by-wire, but the redundant systems can be simpler, lighter, and offer only limited capability since they are for emergency use only.

is this fly by wire??!!!

Assume the Position

Ok, all you stomach sleepers out there--listen up! In order to help prevent the formation of wrinkles, you need to learn to sleep on your back.

Sleeping on your side or stomach creates wrinkles because you bury your face in the pillow and the wrinkles are ironed onto your skin as you sleep. This won't happen if you sleep perfectly still on your back.

HHmmmmm that sucks! So much for beauty sleep.

30 seconds for men!!!

HALF of all women make their minds up within 30 seconds of meeting a man about whether he is potential boyfriend material, according to a study on speed-dating.

The women were on average far quicker at making a decision than the men during some 500 speed dates at an event organised as part of Edinburgh Science Festival.

What makes us yawn?

Next time you're in a meeting, try this little experiment: Take a big yawn, cover your mouth out of courtesy, and watch and see how many people yawn. There's a good chance that you'll set off a chain reaction of yawns. Before you finish reading this, it's likely that you will yawn at least once. Don't misunderstand, i am not intending to bore you, but just reading about yawning will make you yawn, just as seeing or hearing someone else yawn makes us yawn.

While the dictionary tells us that yawning is caused by being fatigued, drowsy or bored, scientists are discovering that there is more to yawning than what most people think. Not much is known about why we yawn or if it serves any useful function, and very little research has been done on the subject. However, there are several theories about why we yawn.

Is there a doctor in the house?

I made a loose analogy between the different stages of an aircraft maintanence engineer's career and a doctor’s career. Mostly about the pay and the responsibilities.
Some of u may think that we have more responsibility than a doctor. As a doctor holds a life in his hands each time he diagnoses a patient. A wrong diagnosis or unsuccessful surgery could lead to death. Our patients are airplanes. Unlike a doctor, a wrong diagnosis or repair can lead to multiple fatalities.

So where does pay fall in? If we hold so many lives in our hands should we be paid as much as or more than doctors? Again it goes back to the old supply and demand. If there is a shortage of mechanics and a great demand then pay will go up to try and attract and keep the employees. So what are your thoughts? Is there a doctor in the house? lol..

This Plane is not Safe!!!!

“Do not fly with this plane, it is not safe.” Those are some pretty direct words — no beating around the bush. If a pilot were to hear these words uttered from a mechanic, he would probably think twice about flying that aircraft.

But what if it was a pilot who said that? What if you were a passenger on an aircraft, buclked in and ready for takeoff, when you heard those words come across the intercom? Believe it or not, that situation did happen to some unfortunate passengers. The Daily Mail reported a few weeks back that a jet carrying 180 tourists was grounded when its pilot made some unsettling comments. The A321 was about to take off when a srange sound came from one of the engines. That is when the captain announced, “I am resigning from my job. Do not fly with this plane. It is not safe. Do not fly with Onur Air.”

The pilot was escorted off the aircraft leaving the passengers onboard an aircraft with temperatures over 100 degrees and no air conditioning. The passengers eventually deplaned, retrieved their luggage, and went to back to the terminal where an alternate flight had been arranged.

When the pilot made the announcement, there were varied reactions from the passengers. Some laughed nervously while others were crying and almost screaming. About 20 of them refused to board the re-booked flight and made travel arrangements to get home.

I don’t know how I would have reacted in that situation. I think I would have laughed at the surreal atmosphere of the situation. I likely would have been one of those trying to find an alternate means of getting home.

Third consecutive failure.

This is going to be a real hard tournament for coach Stoikov, as under his belt this is the third consecutive failure for Maldives. After a remarkable performance against Iran in the opening game of Asian Games, Maldivians hopes for the quater was high....http://www.maldivesoccer.com/news/2006/tournaments/asian%20games/03122006002/

Anawr!!!!!!!!!!!!!!!!

Anwar is a quiet, sensitive Muslim youth in his early twenties. He views the world, under tutelage from his mentor, Master Pasha, in a romantic light, far removed from the pace of modern life in India. Inevitably, as he faces a far harsher reality, it creates the conflict that ultimately drives Anwar..........


WHOOOPS!!!! NO NO Its not me that i am talking about, a hindi movie releasing soon.. Yah "ANWAR"!!!

Afterburners

Afterburners are special devices fitted between the turbine and the nozzle of some turbojets and turbofans. A modern turbine engine is extremely efficient, and there is still a lot of oxygen available in the exhaust stream. The idea behind an afterburner is to inject fuel directly into the exhaust stream and burn it using this remaining oxygen. This heats and expands the exhaust gases further, and can increase the thrust of a jet engine by 50% or more.

The big advantage of an afterburner is that you can significantly increase the thrust of the engine without adding much weight or complexity to the engine.

The disadvantage of an afterburner is that it uses a lot of fuel for the power it generates. Therefore most planes use afterburners sparingly.

So You Want to be an Aircraft Mechanic?

There are a host of reasons why year after year thousands of intelligent individuals attempt to break into the aviation maintenance career field.

They will do anything and everything they can just to get their "Foot in the Door".

Where else are you required to accomplish many tasks with sheer brute force and brawn, exceeding the bodies normal capability? You also must weave your body into unimaginable locations filled with wire and sharp objects, and function with the precision of a surgeon. Our bodies are required to withstand the sun, wind, rain, cold, and the darkness of night. We often use our senses of smell, sound, sight, touch, and even taste to determine whether an item is capable of withstanding the required loads or meeting its objective. Our hands are burned, punctured, smashed, cut, and placed in areas and chemicals that have been deemed too dangerous and harmful for even laboratory animals.

Aviation mechanics must know the systems intimately, and be able to reason, calculate, and rationalize any defect imaginable. These functions must be performed with great speed and accuracy, as humiliation and/or unemployment await the incapable. The mechanic must know, interpret, and attempt to locate vital information in a vast array of books, publications, and bulletins. Then, upon successful accumulation of the data, we must use skills and techniques to produce a job that will sustain lives. Upon completion we must document our every move, and be prepared to enter federal prosecution, which could result in fines, loss of license, and/or sentencing.

Weekends, normal hours, and holidays are often talked about, but seldom enjoyed. Pagers have become as common as the Phillips head screwdriver. In addition, we are expected to be neat, clean, and have a delightful disposition. However, with any job of this caliber, a few frustrations and a little stress is to be expected.

Sometimes it's so good I can hardly stand it myself.

It's no wonder why so many individuals want to be just like me.

SUCK-SQUEEZE-BANG-BLOW!!!!

Whoops! With a title like that you probably think you've hit the wrong website.
While the above title may sound like something out of my writings, it's really just a creative way of remembering the stages of a turbojet engine uses in aircrafts.

Hmmm, that doesn't sound much better, does it?

OK, let's start with the basics.

Most modern passenger and military aircraft are powered by gas turbine engines, which are also called jet engines. The first and simplest type of gas turbine is the turbojet.

In a basic turbo jet, the air enters the front intake (suck) and is compressed by the compressor (squeeze), then forced into combustion chambers where fuel is sprayed into them and the mixture is ignited (bang). The gases which form expand rapidly, and are exhausted through the rear of the combustion chambers and out through the nozzle (blow) providing the forward thrust. Just before the gases enter the engine nozzle, they pass through a fan-like set of turbine blades which rotates the engine shaft. This shaft, in turn, rotates the compressor, thereby bringing in a fresh supply of air through the intake. All of these processes are happening at the same time.

How does the toilet in a commercial airliner work?

Toilets have a bad image because of what we put into them, but if you can get past that and focus on the technology behind them, they can be amazing devices!

The typical home toilet uses a bowl filled with water. When you flush the toilet, it starts a siphon that drains the bowl. Gravity then carries the water into the septic tank or the sewer system.

The problem with this approach on an airplane is that the motion of the vehicle means you cannot use a bowl filled with water -- it would splash out every time a little turbulence came along. Since there is no bowl of water, you cannot use a siphon or gravity to empty the bowl.

Airplane toilets use an active vacuum instead of a passive siphon, and they are therefore called vacuum toilets. When you flush, it opens a valve in the sewer line, and the vacuum in the line sucks the contents out of the bowl and into a tank. Because the vacuum does all the work, it takes very little water (or the blue sanitizing liquid used in airplanes) to clean the bowl for the next person. Most vacuum systems flush with just half a gallon (2 liters) of fluid or less, compared to 1.6 gallons (6 liters) for a water-saving toilet and up to 5 gallons (19 liters) for an older toilet. Amazing heh!!!!!!!

The loss of engines

Two blondes were flying to Miami from Cleveland. Fifteen minutes into the flight, the captain announced "One of the engines has failed and the flight will be an hour longer. But don't worry we have three engines left".

Thirty minutes later, the captain announced "One more engine has failed and the flight will be two hours longer. But don't worry we have two engines left".

An hour later the capain announced "One more engine has failed and the flight will be three hours longer. But don't worry we have one engine left".

One blonde looked at the other the other blonde and said "If we lose one more engine, we'll be up here all day"

"Men can pee standing up"

The reality is men can NOT pee standing up without getting as much as a stray drop on the seat or the outside surface of the toilet. Fragmentation of the urine stream causes particles of urine to dissipate. The larger the distance urine has to travel, the bigger the dissipation radius gets.
Some of you may say, "No, not me! I can pee through a donut from 40 feet above!" Well, mister hand-eye coordination, you are probably one of those people who also never ask for directions. Admitting that you have a problem is half the battle. At some point in your life you need to ask yourself, "Is it worth it? What has peeing standing up cost me in my life?"

Peeing standing up destroys families. Who cleans the bathrooms in your house? Your mother? Your wife? Even if you clean up after yourself, what happens when you are a guest at someone's home, over at your friend's house, visiting the inlaws, or using a public bathroom? Why should someone else have to suffer for your unwillingness to sit down? So a victimless crime!!!!

Eid Mubarak!!

The holy month of fasting over now.
This is the time to celebrate the good things that we have received, Allah’s bounty and our family and friends.
Time to decorate our houses for eid.
Time for a new complete oufit, right down to the shoes.
In between visiting, people make trips out into the streets.
Time to have gr8 fun!!!



Eid ayee, hinithun vamun,

Could Concorde Ever Fly Again?

Concorde - Built in Bristol






Admired by many, flown on by some, loathed by a few - Concorde's place in aviation history is assured.

World first and only supersonic(travels faster than sound) passenger aircraft may have retired three years ago, but engineers in France have been keeping one plane in perfect condition, in an aerospace museum near Paris. The engineers are trying to keep the systems in a state of readiness.
But the biggest question is ofcoz, will it ever or could it ever fly again?
To be honest, I do not have an answer for this question. The engineers say that her systems are not flight ready. But they are keeping her systems in state that the aircraft is as near as they can get her to fly. So there is a hope!


Some major events in the history of Concorde.

Concorde completed its first supersonic flight on 1 October 1969.

The first commercial flights took place on 21 January 1976 when British Airways flew from London Heathrow to Bahrain and Air France from Paris to Rio.

Concorde's image was dented with the crash near Paris on 25 July 2000 in which 113 people died.

In April 2003 British Airways and Air France announced the plane would be retired due to falling passenger revenue and rising maintenance costs.

Concorde's final commercial flight was on 23 October 2003.

On 27th November 2003 the last Concorde landed at its new home - the Bristol airfield where it was built.





Shockwaves form when it reaches the speed of sound.

We Keep Them Flying Safely

If an Aircraft is stopped by an Aircraft Engineer, Managers of Airlines call this........
“The aircraft is Grounded”,
Engineers State: We don’t ground an Aircraft,
“We prevent an unsafe flight” !!!!

Walking back home!!

Its the same every day, no no , ya i mean all weekdays. walk to college and bak home, same route, mostly meet the same ppl but ofcoz not the same weather. Mostly i walk with one or two of my frends, but sometimes its me all alone. thats the time i feel bored n lonely , so i took these pictures on one of the occasions.

A380, A New Way Of Flying.

Taking a clean-sheet design for airlines’ operational needs of tomorrow, Airbus developed the A380 as the most spacious and efficient airliner ever conceived. This 555-seat aircraft will deliver an unparalleled level of comfort while retaining all the benefits of commonality with Airbus’ other fly-by-wire aircraft Families.

Thirty years after launching the world’s first twin-aisle, twin-engine jetliner, Airbus is preparing to introduce its A380 as the first true double-deck passenger airliner for the long-range market. The A380 offers unprecedented levels of productivity, efficiency and economics in passenger service, while the A380-800F cargo version is to be the first commercial freighter with three full cargo decks.

Do You Want To Become A Licensed Aircraft Engineer?

What is required to become a licensed aircraft engineer?


Well, if u are considering a career in aircraft maintenance. consider this.... It involves a lot of studying with relatively low pay and little gratitude.

If u still want to be involved in aircraft maintenance you'll need to first get a basic easa 66 training (that is if u want to become a ground engineer). Mechanic's don't need this.

(go to http://www.easa.eu.int/home/regul_en.html)

This easa 66 training includes 17 modules. U don't have to do all the modules, u decide wich direction u wish to go, there is B-1, B-2 or cat 'A' (certifying mechanic) in easa 66

U may also go for sheet metal work, aircraft deco (paint), trim (cabin maintenance mechanics), etc.

After u have your basic easa 66 training u are classified as a ground engineer without a type-rating.

A type rating is a license on a type of aircraft. For this type rating u will need a certain amount of experience, this is dictated by the easa but most companies have their own experience demands (must be equal or longer then easa's personal experience time demand ofcourse).

When u have the experience on the type that u are trying to get your type rating on then u must do a 'type course' wich typically takes about 4 or 6 weeks theory and 3 or 4 months on the job training for your first licence.

Having completed all that you are probably about 7 years down the line and a ground engineer.

Welcome To My AeroMach Blog

This blog is not meant to advertise myself to companies or to advertise any companies themselves, it just seemed like a fun thing to do to make my own blog and tell whats around me and aircraft maintenance in gereral.

My personal view is that it's better to have an open view of what's going on in the world of aviation then to keep hearing on the news about airplanes being involved in incidents and cancelled flights.

Are there mistakes made in aviation? Yes...

Are there safety nets to prevent these mistakes do not lead to incidents or even accidents? Yes...

So if u are interested in aviation maintenance, just have a look around on the blog.
