Cabin crews 35000 feet above the Sea level : Syed Mohd. Saleh Uddin

(The writer is an Ex CI of College of Aviation Technology and National Institute of Engineering and Technology in Bangladesh who taught in Aerospace Engineering and also Cabin crew courses)

On 5th September 2014 in my Jeddah bound flight I got cabin crew Shehan an Egyptian on duty near an emergency door what was adjacent to my seat also. On 14th October in my return flight I was a passenger in the upper deck. Here an Indonesian and an Arab cabin crews were on duty. In both the cases aircraft was Boeing 747 of Saudia. It is a big aircraft. Generally it flies with more than 400 passengers. In such big air craft cabin crews are very important persons. They play vital roles for the comfort of the passengers and safety of the passengers of the aircraft in emergency. In this article I shall discuss some of their duties while they are in the air, in addition I like to give few tips what a potential cabin crew or serving cabin crews have to know.

There are many airliners worldwide. So, thousands of cabin crews are working there. Still many such jobs are vacant worldwide. Every year among the interested suitable candidates few get this lucrative job. In no case employers select sub-standard one. At present there are many institutes in the developed countries that impart cabin crew training. In Bangladesh including CATECH many other institutes have this course. It is worth mentioning here that if anyone is not fit physically to fly he will never get such job. To become a cabin crew training is not essential but may be an advantage. Here I like to say, I asked Shehan whether she had any training before getting the job. She told no training she got before but after selection airliners given her training. Same case is with many Arab and non Arab cabin crews who are serving in the Saudia. It is ill luck for me, I found no Bangladeshi in my to and fro flights. It does not mean that there is no Bangladeshi cabin crew in Saudia.

However, those who are interested to become a cabin crew they may do a course in such an institute that actually teaches. Few institutes are just interested to issue a certificate teaching nothing but showing few practical movies in power point again and again. A cabin crew must have idea about many materials and matters about aircraft, airliners, air navigation, airport, controlling authorities, hospitality in the air etc. However, if course is not done then also one may apply. If you have required qualities employer may select you and will give you required training. If you are interested don’t hesitate to apply whether you have training or not when you get advertisement. Remember if you get chance to become a cabin crew, you may get chance to fly 35000 ft above the sea level or any level in the aero-space. I wish the best of your luck.

Lastly, I like to conclude the article telling you few duties of a cabin crews. It is not that tough. It is like family duties to other members of the family. Such as serving foods and drinks, take care about the comfort of the passengers as distributing blanket etc, guiding passengers to fasten seat belt and open and how to use toilets. All the cabin crews are taught what to do during emergency, how to deal with panic passengers, how passengers should be taken out from the aircraft during crash landing, how passengers will use oxygen musk, survival kits etc. For aircraft safety they have some duties. They will have to maintain intercom contact immediately with the captain in such case. After successful crash landing in the sea they have to work to keep the moral up of the wounded and other who are alive till their rescue. However, I wish to almighty Allah let there be no misshapen and no air disaster! Let all the flights be as smooth as silk!

Mahad al Haram Mekka and Medina, KSA : Syed Mohd. Saleh Uddin

Our aircraft Boeing-747 was rushing towards Kingdom of Saudi Arabia. Except the air and cabin crews on board all were in Ehram uniform. It included two pieces totally unstitched white cloths. One is worn upper portion of the body and rest one is worn lower portion of the body. To bury a Muslim death such white uniform is used also.

Passengers were time to time saying loudly “LABBAYKA ALLAHUMA LABBAYKA……………”


It means reciting ‘TALBIA’ which is a ritual of the hajj. In such days if one closes his eyes and tries to feel about hajj pilgrims a clear view will appear that aircrafts from all directions are moving towards Mekka that are full of pilgrims in same uniform. All of them are reciting ‘TALBIA’. Many are weeping or sobbing. Tears are following down through the cheeks of many. Same scenarios will be visible in the Jeddah airport, in the bus towards Mekka and finally while moving from Hotel for the first Omrah that include Tawaf around Khana e Kaba and Saiwee between Safa and Marwa ie two hills where Hajera(PBUH) the mother of Prophet Ismail ran 7 times in search of water to save thirsty child Ismail and finally Allah presented her Jam Jam well which till date is alive and supplying fresh drinking waters to pilgrims what are carried worldwide by them to drink. It’s a miracle. Muslims believe, it also gives some nutrition while one is hungry.

When ‘KHANA E KABA’ will be visible saying ‘TALBIA’ will have to be stopped. It’s the ritual. Most probably philosopher poet Allama Iqbal in such condition written ‘KABA TU DEKH LIA, KABA KA KABA TU DEKHO’(YOU HAVE SEEN THE KABA, NOW YOU SHOULD SEE THE KABA/OWNER OF THE KABA). Actually Allah ordered Muslims to visit Khana e Kaba not to see that but to obey him. So, Muslims go there and do Tawaf and Saiwee when they urge to Allah but not to his said Home. It is quite symbolic. He never dwells there. During the Tawaf and Saiwee devotees walk and express everything to creator, repent for sins, ask for the best for themselves and everybody.

As a matter of fact Hajj rituals are not that easy. But these are easier to the young men and women. I am astonished when I saw Arab children wearing Ehram uniform were more energetic than their parents. However, these were very interesting events for children but for their parents those hard rituals are to please omnipotent Allah certainly. Conscious pilgrims try to search Allah following all its ritual properly. They do Tawaf and Saiwee together whereas in the other MUSLIM RITUALS men and women are not permitted to do side by side. They stay together in the field of Arafa in 9th Jilhajj. They stay there in the tents from sun rise to sunset. Then after sunset they reach Mujdalefa where they spent the night under the open sky in the plain, in the slopes of the hills, over the ridges of the hills and even besides the streets. We arranged our night beds by the side of a road. Over us there were a Kubri (over bridge) where there were pilgrims. Men, women, children all took their shelter for the night where they got vacant place. It is 10th of Jilhajj when all the pilgrims go to Mina and stay there till 12th Jilhajj or may stay till the next day. From there on set (written in Fiqh) conditions pilgrims go to throw pebbles till 12th or 13th Jilhajj. Then all return to Mekka and do Tawaf e beda. However outlines are given here what each pilgrims are doing from the first hajj what our last Prophet (PBUH) became tradition. Pilgrims must remember hajj is not mere a tradition rather a path to find Allah. So, they must be sincere to follow the ritual properly utilize the time to please Allah leaving back biting, querling, fighting each other, unnecessary marketing, blaming and criticizing Muallim’s members etc. Response to Allah’s call must be in the way of Allah who teaches us to be generous hearted. Pilgrims must remember that they are there to do some pains taking rituals for their salvation and that must be done in proper prescribed way. All the prohibited and heinous activities must be avoided.

Here my aim is not to express the rituals of Hajj but my aim is to tell about Mahad al Haram and activities of Mahad al Haram. While in Mekka I had enough time to visit all the floors of the Grand Mosque situated around Khana e Kaba. In the hajj time prayer halls are too busy. But after the hajj fewer pilgrims come to do Omra throughout the year. So, Saudi Government decided to utilize prayer halls for education purposes. Government established Mahad al Haram in both the Harams(Haramyn) ie the grand mosque of Mekka around Baitullah and Mosque of the prophet(PBUH) in Medina. I was lucky enough to sit in both Mahad’s few classes. Their media of teaching is Arabic. So, I didn’t understand their lectures.

I searched someone who could understand me. In the Mahad of Mekka I saw many Rohinga Bangali students. But present generation of Rohinga Bengali there mostly became Arabic speaking.

Faisal Shams a Jama (University) student came forward to help me. He failed to communicate with me in Bengali. Our communication was in Urdu. They speak better Urdu because they get many Urdu speaking pupils from India and Pakistan with whom they communicate.

From him I came to know in the Mahad in Mekka total more than 125 Bengali (probably Rohinga Bangali) students are studying in different level. In Jama level about 30 Bengali students are studying. They learn here Kitab, Sunnah, Sharia, Ulomul Quran etc. Names of the classes are different. As in Sharia classes Ula Ali, Samia Ali, Salasa Ali, Raba Ali etc. In under graduate level classes are Ula Mutwasser, Samia Mutawasser, Salasa Mutwasser and in lower class three classes are named as Ula Sanawi, Sania Sanawi and Salasa Sanawi. He further added in Jama class young students of 20 to 25 years old are eligible to take admission. In under graduate level students of 15 to 20 years and in lower level students of 12 to 16 years can take admission.

Ustads(teachers) of Mahad al Harams are highly educated. Among them in Mekka Mahad few are as follows:

  1. Dr. Abdur Rahman Ahadal

  2. Dr. Abdul Wahab Risini

  3. Dr. Abdul Hafiz al Gazi

  4. Dr. Abdur Rahman al Sehri

  5. Dr. Zibril Mega

Names of few ustads(teachers) in Mahad al Haram in Medina are as follows:

  1. Dr. Allama Mosharraf Abdullah Musharraf

  2. Dr. Mohammad Ahmed Horratani

  3. Dr. Sheikh Azim Ahmed

  4. Dr. A. Zafar

  5. Dr. Abdul Moin Ekram

In the Mahad al Haram in Medina a student of second year named Hamza M. Dost Mohammad helped me giving its information. He is from Multan, Pakistan. I could talk to an Urdu speaking Ustad named Abdur Rahman. He teaches in the Riasatul Haram. Here students will become Hafez e Quran. Once before Asar prayer I saw hundreds of children (Arab, Black immigrants, Rohinga Immigrants and may be children of other immigrants) are learning their lessons. From these students many will get chance to study in any of the Mahad al Haram.

I came to know Mahad is recognized by Saudi Government as a University. It’s passed out Jama students may get job in Saui Arabia or any other Arab countries. Now they are serving in the various mosques of Saudi Arabia. I saw them in Khaledia mosque giving hajj training. Time to time there were arrangement to translate lectures of Mahad’s teachers in different language like Vahasa Indonesia, Urdu, Bengali etc. Translators might also be Mahad’s students.

I believe in course of time Mahad will become a famous University for the Muslim world. Students from the home and abroad will go there for higher education. This University will give pure knowledge about Malik/ Owner of the Kaba (Kaba ka Kaba). Grand mosque around Kaba and Mosque of the Prophet (PBUH) will become very busy campus for international students who will do research to know more about the creator Allah and his creations. May Allah bless us all!

The tilapia has been sequenced:News from CIRAD website for further dissemination

The tilapia has been sequenced

03/10/2014 – Press release

The genomes of five species of cichlids, which include tilapia, were recently sequenced and compared by the CGC (Cichlid Genome Consortium), of which CIRAD is a member.

The results were published in the 18 September issue of the journal Nature .

The five genomes were sequenced at the Broad Institute in Washington (a leading sequencing centre), with funding from the NIH (National Institutes of Health, USA). Of the 27 laboratories that co-signed the article in Nature , CIRAD, the University of Stirling (UK) and the Agricultural Research Organization (Israel) are particularly interested in the consequences of the project for aquaculture, and will be using the tilapia reference sequence in order to speed up the identification of sequences linked to worthwhile characters.

CIRAD has primarily looked at the sex-ratio, thermosensitivity and salt tolerance, and is going on to study food efficiency.

Tilapia, the “aquatic chicken”

Tilapia, an African cichlid, is one of the world’s most widely used model fish species for studies of genetics, physiology, endocrinology, toxicology and behaviour. With an output of 4.3 million tonnes from more than 100 countries worldwide (primarily, but not exclusively in the Tropics), tilapia is currently the second largest group for aquaculture worldwide, after carp, which are mainly produced and consumed in China.

All the forecasts suggest that tilapia (which is often presented as the aquatic version of chicken) is set to become the main farmed fish species of the future.

Sex determinism and differentiation

With tilapia, sex has to be controlled if farms are to be profitable, since the males grow faster than the females, which lay eggs roughly every month and keep them in their mouth to protect them for around ten days, during which they are unable to feed.

Most producers currently use hormones to ensure single-sex, male populations. However, this raises many questions as to the sustainability of such treatments: what impact will these steroids have on the health of the farmers using them and of consumers, and on water quality and biodiversity?

Since 1985, CIRAD has been working on new ways of controlling sex without using hormones, based on genetic and/or environmental approaches. It was the first organization to demonstrate the possibility of producing YY males with single-sex male progenies without using hormones.


CIRAD was also ahead of the field in detecting the masculinizing effects of the high temperatures used with tilapia in its early stages; similar results have since been obtained for many other species. In order to optimize and speed up breeding programmes, its scientists (the AquaTrop group belonging to CIRAD’s INTREPID research unit) are working to find markers linked to sex and thermosensitivity.

Molecular markers were recently identified for early phenotypic sexing, and have been tested by an ANR project-Emergence (SexTil) with a view to producing commercial kits. These kits should serve to accelerate the production of YY males for genetic sex control and/or to breed parents with heat-sensitive progenies in order to control sex through temperature rather than using hormones.

Salt tolerance

Adaptation to salinity is necessary for a number of countries keen to farm tilapia in brackish water or in the sea (shortage of fresh water, conflicts of use or concerns about preserving the resource). For instance, in the Philippines, most tilapia is produced in brackish water. CIRAD and the BFAR (Bureau of Fisheries and Aquatic Resources) have developed a salt-tolerant strain (Molobicus ) using conventional genetics.

The reference sequence will facilitate the identification of salt tolerance markers, with a view to identifying and breeding highly tolerant parents locally (thus avoiding the dissemination of interesting strains from one country to another, and the resulting genetic contamination).

An omnivorous diet

Unlike most farmed sea fish (particularly salmon, sea bass, bream, etc), for which fish meal and oil are an essential or at least an important part of the diet, tilapia, which is microphytophagous (it can eat and convert phytoplanktonic algae and cyanobacteria), is sufficiently opportunistic to be classed as omnivorous. It is therefore towards the bottom of the trophic chain. Under extensive farming conditions, tilapia can thus be produced without artificial feed, by stimulating primary production (plankton) by fertilizing the ponds.

Along with carp, it is therefore one of the species that can be produced without using fish meal and oil obtained through fishing, hence without impacting on fish resources.

In practical terms, the tilapia reference sequence will therefore make it easier to breed strains suitable for farming, by identifying genetic markers linked to characters of aquacultural interest and developing kits like the one developed for early molecular sexing of tilapia. In the short term, it will also foster the switch to rational fish farming that pays greater heed to producers, consumers, and also the environment.

From a more fundamental point of view, this work enables a clearer understanding, on a genome level, of the mechanisms that lead to the birth of new species (speciation). In the great lakes of East Africa, speciation studies of cichlids over the past 75 years have revealed “adaptive radiation” phenomena, characterized by the very rapid appearance of a large number of species (explosive speciation) from a single ancestral species (or a very small number of species).

These new species are extremely morphologically and ecologically diverse, and each one is adapted to a specific trophic niche (adaptive radiation). These phenomena do not have any equivalent in vertebrates.

The CGC’s work shows that the mechanisms that lead to this type of adaptive radiation are based on an explosion in the duplication of genes, many of which have been conserved despite evolution and which will go on to develop new functions (neo-functionalization) and play a role in adaptation to new environments.

Hypocrite : A Poem by Dr.Syed Md. Zainul Abedin

When ugly hypocrites join hands
Innocent people lose their hope
They are menaced by the bands
They seek divine help to cope
But divine help is not that easy
People suffer from fear and stress
Hypocrites howl to keep them busyTheir normal lives change to mess


The brave hearts that can endure

The nasty tricks of horrid devils

Win at last and become secure

From the lethal offense of evils


We need courage to fight the hypocrites

Patience is extra power for their treats
