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!!!!

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.
