AF447:THE FALL OF THE AERIAL TITAN.




A33O-203 A modern aerial transporter that keeps the attitude same to that of the RMS Titanic.
Keeping away Titanic and it's story from our discussion.I shall focus on A330 AND it's flight AF447's unexplainable crash.

I am working in aviation sector
specialized in engineering and partially dealing with the same model Aircraft.Like me almost all technical persons who are presently dealing with this Aircraft believes that the Machine is so flawless that it can't crashed unless anyone tries to crash it.AF447 was in no way diferrent from the one i am saying about,but it was fated to go into the unfathomable depth of mystery of it's crash alongwith 228 human lives of whom none were to found anywhere

On Sunday 31 May 2009, the Airbus A330-203 registered F-GZCP (in the picture)operated by Air France
was programmed to perform scheduled flight AF447 between Rio de Janeiro GaleĆ£o and
Paris Charles de Gaulle. Twelve crew members (3 flight crew, 9 cabin crew) and 216
passengers were on board. The departure was planned for 22 h 00.
Towards 22 h 10, the crew was cleared to start up engines and leave its parking position.
Takeoff took place at 22 h 29.
The takeoff weight was de 232.8t (for a MTOW of 233 t), including 70.4 tonnes of fuel.
The crew contacted, successively:
• RIO DE JANEIRO approach control,
• the CURITIBA ATC centre, which cleared it to climb to FL350 at 22 h 45 min 26 s,
• the BRASILIA ATC centre at 22 h 55 min 41 s,
• the RECIFE ATC centre at 23 h 19 min 27 s, the airplane being stable at FL350,
• the ATLANTICO ATC centre on HF at 1 h 33 min 25 s.
At 1 h 35 min 15 s, the crew informed the ATLANTICO controller that they had passed the
INTOL2 point then announced the following estimated times: SALPU at 1 h 48 min then
ORARO at 2 h 00. They also transmitted their SELCAL code and a test was performed.
At 1 h 35 min 46 s, the controller asked them to maintain FL350 and to give their estimated
time at the TASIL point.


Between 1 h 35 min 53 s and 1 h 36 min 14 s, the controller asked the crew three times for
its estimated time at the TASIL point. There was no further contact with the crew.
A point why the investigators are suspecting the speed computation of aircraft and related pitot tube sensing the speed is that twenty-four automatic maintenance messages were received between 2 h 10 and 2 h15 via the ACARS system.ACARS refer to Aircraft Communications Addressing and Reporting system,which time to time keeps generating and transmitting messages to ground regarding faults in the aircraft.And the messages recieved showed inconsistency between the measured
speeds as well as the associated consequences.

Now,there are many system responsible for sensing the speed of an highly advanced aircraft specially A330 and the pitot tube(A330 has 3 numbers for fail safe) is the basic of all(found in all aircraft) and the base for sensing forward air pressure,it in turn activates a modern means,an air pressure transducer(converts mechanical air pressure to calculated electrical signal) which gives the data to ADIRU.ADIRU is Air Data Inertial Reference unit,this system processes this data systematically with other data and gives a final accurate result.Here,Airspeed read by pitot tube to the sum up of integration given by ADIRU was inconsistent might be due to intermittent clogging to pitot probes.
In this ocassion pilot should always fly the aicraft rather than the autopilot.Mystery arises when one fault mesage was recieved showing discontinuation of AUTOPILOT,thats too by unexplainable reason.And since there are series of system involved in order to give the final output airspeed accurately,it is almost next to impossible to determine the cause and failure when u are left with debris and noone to tell the story and all clues washed away by the atlantic

There won't be any end to our queries,me knowing the A330 & you not having the basic knowledge.All these experiences shows the human limitations time to time,but great is human nature whose determination is invincible.As the journey hasn't ended like it always go on,so it will.............

the assamese legend


"Could it be that there is no man fit enough in Your Majesty's realm? What are the enemies? They are after all ordinary mortals. Shall we not find similar men in our country? Your Majesty should only confer the dust of your feet, and the man equal to the occasion will be readily found."

the words that changed the medieval history of assam;came out spontaneously from the mouth of a noble scarf-bearer.this made the king Chakradwaj Singha believe that this noble laureate must be the commander of the ahom army(the origin of assamese) to lead the wall against moghul warrior;who by that time had already captured almost the whole of india to make the moghul dynasty.
the king gifted him a sword made of half gold,the hengdang.he defended guwahati first and placed a barrier at sariaghat(other bank of brahmaputra near guwahati) to blockade the moghul force led by Ram Singh for the 18th and the last attempt made by moghul.

though we don't find any confirmed portrait of him to be found in the history but preserved pen-picture of describe him as moon at it's full phase;noone was capable of staring at him.

he beheaded his maternal uncle(mama) when the fellow was found with insincere attempt to build the wall of blockade.
"My uncle is not greater than my country"("Desotkoi Momai Dangor Nohoi" in Assamese).
the verse is still cited wherever the name of this scarf bearer turned commamder-in-chief's name is recalled.

Ram singh even tried to foul play the war by sending an arrow attached with a message that cited that the commander sold the sovereignty of ahom dynasty to moghuls' for one lakhs rupees.though,the kingh initially lost faith on him,but under the pursuance of prime minister Atan Borhohain,the king still insisted on the commander to continue his post.


his command over the army led to highly innovative way of guerrella warfare tactics,which was unintelligible to the moghul knights and warriors.he fought with a few thousands of warriors in small boats to resist the moghul suppression by lakhs of warriors in ships in the river Brahmaputra.it was a sure defeat of the ahom,but the physical and mental stamina of the commander even during severe fever to fight back till last,let ahom dynasty snatch the cake from Ram Singh's and moghuls' mouth by pushing the moghuls backyard of Saraighat.to this great leader Ram Singh wrote :

"Glory to the king! Glory to the counsellors! Glory to the commanders!Glory to the country! One single individual leads all the forces! Even I Ram Singh, being personally on the spot, have not been able to find any loophole and an opportunity!"

the commander fought till his last.though he died in the midst,while giving colours to the plan of an attack over moghul; he had already built an image about the ahom bravery in the history of medieval history of assam.

hallowed be the commander LACHIT BORPHUKON

WE PEOPLE GROW UP BOTH IN AGE AND NUMBERS, BUT OUR ENVIRONMENT IS THE SAME IN SIZE SINCE BILLIONS AND BILLIONS OF YEARS,MOTHER EARTH DOES NOT GROW.WE MAY BE BLAMING THE FIRST WORLD COUNTRIES FOR WHAT THE ECONOMIC ENVIRONMENT IS TODAY.LIKE A COMMON MAN WHO THOUGH HIMSELF BEING A FARMER THINKS OF MAKING HIS SON/DAUGHTER A DOCTOR OR AN ENGINEER,AND FORGETS WHERE FROM WILL THEY GET FOOD IF EVERYONE IN THE WORLDS STARTS PLANNING AND BECOMING A DOCTOR OR ENGINEER;SAME IS THE SITUATION WITH US ALL WE DON'T PLAN THINGS IN LIFE.WE STILL CRAVE FOR THINGS,LIKINGS AND REMAIN SELFISH.TODAY,WE STILL FIND FAMILIES WHO STILL WANTS SON RESULTING IN NUMEROUS SIBLINGS,OR COUPLES PLANNING FOR NUMBERS OF KIDS.IT IS INSULTING WHEN THIS THINGS OCCUR IN WELL EDUCATED FAMILIES.SO, BEFORE IT IS ALL OVER(WELL THE RESOURCES)LETS SAVE IT.AT LEAST BEFORE EVERYTHING IS ALL OVER PEOPLE MIGHT OPEN THEIR EYES TO SEE WHAT THEY HAVE DONE.WE ALL LIVE AND DO BUSINESS OVER NATURE EITHER DIRECTLY OR MODIFYING IT SCIENTIFICALLY,BUT WE SHOULD NOT FORGET THAT OUR SHARE IS SAME AND EVERY EXTRAS IN OUR OFFSPRING DIVIDES OUR SHARE AMONG THEMSELVES.SO,CAN WE MAKE IT HOW LONG CAN WE ALLOW THIS DIVISION TO CONTINUE.WELL,IT'S ALMOST AT IT'S END.WHAT IS RECESSION?HAVE WE EVER THOUGHT ABOUT THE MATTER?IT'S A SOCIAL ACCIDENT MET UP ECONOMICALLY.EXPERTS FROM NATIONAL BUREAU OF ECONOMIC RESEARCH (NBER) DESCRIBE IT AS TWO QUARTERS OF NEGATIVE GDP GROWTH,BUT IT'S NOT ALL IN TWO QUARTERS AND WILL BE LONG IF WE DON'T CHANGE.IT ISN'T ALL OF A SUDDEN.......IT IS ALL THE RESULTS FROM THE HUMAN ACTIVITIES.NOW IT IS OUR RESPONSIBILITY TO START ACTING IN THIS HIGH TIME.BEFORE WE LOOSE THE CLOTHES OVER OUR SKIN,THE FOOD FROM OUR MOUTH AND THE ROOF ABOVE OUR HEAD(THE COMMON INDIAN DIALOGUE)

the religion called HUMANITY...(hindu temple with muslim priests)


WELL, I HAVE BEEN ALWAYS THINKING ABOUT THIS.HUMANITY THE RELIGION OF ALL.NO DOUBT,OUR RELIGION COMES FROM OUR FATHER,BUT TOLERANCE TO ALL INDIVIDUAL IRRESPECTIVE OF THE DIFFERENCES WAS ALWAYS THOUGHT TO BE GREAT.BUT,WHAT WAS MOST EXULTING WAS A HINDU TEMPLE BEING GUARDED BY MUSLIM PRIESTS AND THAT'S TOO IN ONE OF THE MOST BACKWARD PLACES WITH CONFLICTS AND RIOTS PREVAILING AMIDST TABOOS AND TRADITION.WHAT SHOULD HAVE BEEN FAR BEFORE HAS NOW AT LEAST STARTED EXPANDING IT'S WING AND THE MOST EXHILARATING WAS THE FACT IT STARTED FROM PAHALGAM.
SITUATED ON THE BANK OF A RIVER,A 900 YEAR OLD SHIVA TEMPLE,THE ONLY HINDU SHRINE IN THE KASHMIR VALLEY.
AFTER MIGRATION OF KASHMIRI PUNDITS FROM A NEARBY VILLAGE,TWO MUSLIM PRIESTS-MOHD ABDULLAH & GHULAM HASAN KEPT THE DOORS OF MAMALAKA TEMPLE OPEN AND IT'S BELL STILL RINGING,MAKING EVERYONE TO REMIND THEMSELVES ABOUT THE OMNIPOTENT IN THE SILENCE OF THE VALLEY.
THE TEMPLE ACTUALLY FALLS ON THE WAY TO AMARNATH AND IS USED AS HALT FOR THE PILGRIMS ON THE WAY.THE MUSLIM PRIESTS MANAGES THE TEMPLE INCLUDING RITUALS AND ALWAYS KEEPS IN MIND THAT NO ONE GOES WITHOUT PRASAD.
TODAY THE TEMPLE WHICH WAS AT THE BRINK OF BECOMING RUINS STILL STANDS TALL.IT WAS HUMANITY AND FAITH THAT IS NOW ERECT.GOD IS ONE.HE TOO LOVES HUMANITY.

THEY THINK LIKE ME
