AIRCRAFT INSTRUMENTS

(continued)

Instruments Concerned with Information about Conditions on the Outside of the Airframe

Temperature. The outside air temperature (OAT) gauge gives the pilot general information about the temperature of the air immediately surrounding the airframe. This will enable him to assess the influence of temperature on certain performance aspects of the air-nil He needs to know particularly whether the temperature is thin certain limits in humid conditions so that there is danger of ice forming. This enables action to be taken to heat the affected areas. Critical parts include the leading edges of the wings, control surfaces of the tail unit, engine air intakes and the pilot head. On the other hand there are certain parts of the airframe that
might possibly become overheated because they are close to something like an engine or a generator producing a lot of heat. The temperature of important zones of the airframe in the vicinity of a heat-producing component, for example the rear spar of a main plane containing a "buried" jet engine, are monitored by electrical temperature bulbs. Cabin temperature indicators are normally fitted to modern
aircraft to enable the pilot to confirm that the automatic system con
trolling temperature is in working order. Cabin humidity indicators
may be fitted but humidity control systems are rare.


Pressure. It is important to know the pressure inside the passenger cabin because it must be neither too high nor too low for human comfort. It is also important to know the difference between the air pressure outside the cabin and the air pressure inside it because it represents a force exerted in normal circumstances in an outwards direction. The difference in pressures must be kept within limits imposed by the strength of the fuselage. The cabin altitude indicator is the instrument monitoring passengers' comfort and the cabin differential pressure indicator monitors the margin of safety. Other pressures concerned with the airframe that have to be watched are the hydraulic and pneumatic systems used in powering)
controls of such moving parts as brakes, undercarriage and so on Instruments Concerned with Information about the Aircraft's Electrical System.


Havo maydonchasi tashqarisidagi sharoitlar to'g'risida ma'lumotga ega vositalar

    Harorat. Tashqi havo harorati (OAT) o'lchovi uchuvchiga samolyot atrofini o'rab turgan havo harorati haqida umumiy ma'lumot beradi. Bu unga havo ta'sirining ma'lum jihatlariga haroratning ta'sirini baholashga imkon beradi. Xususan, namlik sharoitida haroratning ma'lum bir chegara bor yoki yo'qligini, muz hosil bo'lish xavfi borligini bilish kerak. Bu zararlangan hududlarni isitish uchun choralar ko'rishga imkon beradi. Kritik qismlarga qanotlarning etakchi qirralari, quyruq blokining nazorat yuzalari, dvigatelning havo olish joylari va uchuvchi kallalar kiradi. Boshqa tomondan, samolyot parchalarining ma'lum qismlari mavjud

Ehtimol, ular haddan tashqari qizib ketishi mumkin, chunki ular dvigatel yoki generator kabi ko'p narsalarga yaqin. Issiqlik ishlab chiqaruvchi qismga yaqin joyda havo kosmosining muhim zonalarining harorati, masalan, "ko'milgan" reaktiv dvigatelni o'z ichiga olgan asosiy samolyotning orqa naychasi, elektr lampalar tomonidan nazorat qilinadi. Idishning harorati ko'rsatkichlari odatda zamonaviyga mos keladi

samolyot uchuvchiga avtomatik tizim con ekanligini tasdiqlash uchun

trolling harorati ish tartibida. Idishning namligi ko'rsatkichlari

jihozlangan bo'lishi mumkin, ammo namlikni boshqarish tizimlari juda kam.

    Bosim. Yo'lovchi idishni ichidagi bosimni bilish juda muhim, chunki u odamning qulayligi uchun u juda yuqori yoki juda past bo'lmasligi kerak. Idishning tashqarisidagi havo bosimi va uning ichidagi havo bosimi o'rtasidagi farqni bilish ham muhimdir, chunki u normal sharoitda tashqi tomon yo'naltirilgan kuchni anglatadi. Bosimlarning farqini fuselage kuchi o'rnatilgan chegaralarda ushlab turish kerak. Kabinaning balandligi ko'rsatkichi - bu yo'lovchilar qulayligini nazorat qiluvchi asbob va idishni differentsial bosimi ko'rsatkichi xavfsizlik chegarasini kuzatadi. Eshitishni nazorat qilish kerak bo'lgan boshqa bosim gidravlik va pnevmatik tizimlardir)

tormoz, avtoulov va hokazo kabi harakatlanuvchi qismlarni boshqarish samolyotning elektr tizimi haqida ma'lumotga ega asboblar.

Sujon: Hello, Jamiya! How are you?

Jamiya: I am not fine. What about you?

Sujon: I am fine. But what happened to you?

Jamiya: Nothing serious, but I feel very weak.

Sujon: It seems to me you are very careless about your health. May be you do not take physical exercise regularly.

Jamiya: Yes, you are absolutely right. I am not habituated to take physical exercise.

Sujon: But you should know that physical exercise is very important to keep us fit. Because a sound mind lives in a sound body.

Jamiya: Yes, you are right.

Sujon: If you do not take physical exercise regularly, you cannot keep yourself fit and do anything properly. Besides, you will become idle.

Jamiya: It seems to me you are absolutely correct. Now tell me what I should do.

Sujon: You should take physical exercise regularly. Apart from this, you should have a balanced diet to keep yourself fit.

Jamiya: What do you mean by a balanced diet? Please tell me in detail.

Sujon: A balanced diet means to take regular food containing all the necessary ingredients needed for health in right proportion.

Jamiya: I see, both taking physical exercise and eating a balanced diet regularly are very important for good health.

Sujon: Exactly! I hope you will follow both of the rules to keep yourself fit.

Jamiya: I highly appreciate your wise suggestions. Thank you.

Sujon: You are most welcome.

c) Somebody thanks you for something



Izza: Hi, Nick. Do you need help?

Nick: Hi, Izza. Yes, I think I really need your help.

Izza: What are you doing? Are you going to move?

Nick: No, I’m just cleaning my room. As you can see, it’s so messy.

Izza: I think you’re right. Let me help you.

Nick: You’re such an angel! I really appreciate your kindness, Izza.

Izza: You’re welcome.

Nick: Do you like doing the house chores?

Izza: Yes, I do. I was trained by mother when I was still young to do the house chores in our house.

Nick: Wow! Good for you. Me, I’m not used with these since my mother does all the cleaning by herself when I was young. But I’m a good cook. That’s my job, you know.

Izza: Really? That’s great!

After an hour…

Nick: Whew! That was tiring.Thank you again, Izza.

Izza: No problem, Nick. I live just beside your apartment so let me know when you need help again.

Nick: Really? Thank you very much! Thank you for all your help.

Izza: You’re very welcome, Nick.

Anytime.

Nick: Hmm… Is it ok if you stay here longer? I would like to cook something for you.

Izza: Oh, I would love to!

Nick: Great! Give me time and I’ll make a special meal for you.

Izza: You’re so nice. Now, I don’t have to go to your restaurant to taste your

cooking. Thank you, Nick.

Nick: No, I should thank you. ThankThank you for your time, Izza.

Izza: That’s nothing..
