Why wingtips?

Winglets, those upward turning ends of aircraft wings ,boost the performance by reducing drag. this is accomplish by reducing the strength of the wingtip vortices form by the difference between low pressure on the upper surface of the wing. these vortice represent an energy loss and increase in drag. in essence ,the winglet provides an effective increase in the aspect of the wing without extending the wingspan. winglet come in variety of styles- the airbus 320 has a very small upper and lower winglet :
A320
the boeing 747-400 has a conventional ,vertical upper winglet ;
B747-400
and the boeing 737 has an eight-foot winglet with curving transition from wing to winglet.

B737-800
since the airflow around the winglet is quite complicated, the winglet must be carefully designed and tested for each aircraft.in the past winglet is likely to be retrofitted to existing wings, but new airplane are being designed wit winglets from the start.(adapted from fundamental of fluid mechanic text book ) this subject is my lovely subject coz always deal with the formation and principles of flight. i cant score it well in last semester but i must do it well in this semester .

Meaningful life everyday

Life is just like our main course and you are the chef . Some chooses to be the 5 star and fabulous chef in the hotel but some just likes to be a faithful family and unpaid chef. salted,hot,sweet,bitter,and sour...all follows what you want. If you intend to make your main course contain all of the taste, make sure you do it correctly.
How do i arrange my every meal? I would like to take something bitter and salty first, then followed by a soup with hot and sour taste and finally with lovely and sweet desert. Some ask why dont you just leave that bitter food? Erm...Sometime the raw material is not all available in the market and you have no choice to take it. what the god gave, you just accept it. I feel good and thankful as what i have contain all the taste. Now is the time for me to arrange the flow of dishes i should cook. Balsam pear will never turn sweet and every meal you have god will just give you a balsam pear. God know that not everyone like to cook balsam pear, so the most marvelous meal god will just prepare for you with balsam pear. Wana be a good chef? Just change the way you cook and flavoring you put. Taste the bitter and you will feel so sweet when you have desert in the end of your meal. If the courage for you to start shearing the bitter melon into slice also don't have how are you going to start having all the material given?
I used balsam pear to describe all the opportunity that we have and just do not want when given balsam pear then you just leave it in the kitchen. No matter what is your golden chance(life) prepare for you, just cook it and changing all your style to adapt it. Don't ever think of people will change for you, try to catch all the chance and never blame that 'life is bitter'. No one succeed without undergoing all these 'balsam pear life'. I will try all my best to be a pilot,no matter what i am given to prepare for pilot meal. I wan to be a pilot and i must be a pilot as i dream to be a pilot.

Life for myself

What if you are feeling lonely due to doing a lot thing and when the time for you to rest also will feel uneasy? I know what i m doing and also worry about my studies now. Feel myself seldom sit down for reading, always go out and talk a lot. Really hate of myself unable to control my chatting and always wasting lot of time. Lose direction, overwhelming by others and cant make decision rightly. scare to take risk ,scare to blame by ppl.
How ??? i should doing all according to my decision and not always hesitate of doing wrong. I must be confident .yup...be improve. Feel myself can control my emotion already, stand for humiliating and criticizing. sometime is better to be patient then act accordingly. cultivate and foster to be a gentlemen.

Memorable experiences

Erm …one week have passed and I gain lot of experience during this duration. Let me spew it out now. From Monday to Friday still the same nothing special except my public speaking class at Wednesday, it gave me a lot of courage to speak in front of the public. Unfortunately I can’t continue it this week due to my palapes swimming is started d… Thursday was my course mate birthday so I did endure my tiredness until the midnight for his celebration although Thursday is the most exhausted day.
Friday in the morning I wake up and no other things to do except taking out my black cut(leather shoes) and shine it until mirror shine. As a navy, it is important to know how to shine a shoe and ironing a perfect smooth uniform. No wasting of time and busy the whole day preparing for departing to naval base lumut. I can’t believe myself that I slept just after half an hour the bus start departing. Really kheng ah. Arrived at 545am sharp the time for praying. I m not so I just cleaning up myself in the mosque toilet and wearing up delta rig.
After finish my breakfast then we entered the base d… feel exciting of watching the entire warship anchor at the jetty. Yo…helicopter base some more. Shipyard, logistic, and a few crew colleges all are very huge. Our bus stop at a place call tangkas/DCFF(damage fire fighting control) our senior is doing their NBCD (nuclear biological chemical defense ) and we cadet just learning apak( alat pemadam api kecil) Erm…interesting of watching senior fighting chemical fire by wearing breathing apparatus. The interesting session has reached which we all called to enter a simulator that is exactly like a ship (frigate model) and the instructor give some briefing on how to save a shipwreck during hit by a bomb. When the simulation is start we all feel like head spinning because they want us to feel like in the thunderstorm sea. Pis …a hole spurt out water with very high pressure and all of us trying to cover it with our body. But the water ejects out more and more place caused the ship flooding with water and ship shaking continuously. In the end the sea water all cover up our whole body and the only way for us is to floating up to breath.
For the afternoon session, visiting trips to warship call 1505 KD SRI INDERAPURA. A huge ship that I ever seen. Main use for cargo and conveying troop and tank. Two canon with rocket launcher. I don’t know how to descried by using word for my feeling. Just like the feeling looking at giant aircraft in the sky. I love natural and wanted to go for sailing that is the reason why I join navy. I hope that I will have chance to sail once in my life with warship. I like beach and I like swimming as well. Diving is my interested but for the timing now I m not financial able to do so. Maybe in the future I would have chance to dive at every spectacular island in the world after I become a pilot.
In the following days, my life would become more and more busy as a result of fully activity with palapes and myself. To be continue ….shalom

Third semester

Oh ya…this is my second Saturday and 1st training of reserved navy of my third semester. During this two week I find myself use fully of the time. But I wasted a lot of time in sewing and ironing my navy uniform. What I had learnt from sewing is patient, that’s why the patiently of girl is much more than guys due to sew a nice line is not easy. For my activity 'zhong qiu' side I m busy with recruiting new member, busy for three days and finally I got 107 of new member registering in my group. Now I’m head aching of how to keep them in my group…
Erm….talk back my today training, shalom the whole day. Last time, I was so scared of being picking up to be a leader or delivering a speech. But, I find myself have lot of improvement after reading that self improve book ‘the power of subconscious mind’ on the way of how to facing public and controlling my mind to the path of successful. Now I start worrying on my study, too much of activity will ruin my academic performance. How to manage an effective time is now the time for me to learn and drill. I don’t want manage in order to get a moderate result instead I m doing the best to obtain my 1st class degree for this semester.
