    Если я правильно понял то работа с отказом топливного насоса одного из четырех баков это внештатная ситуация. В процессе выполнения полетного задания насосы работают постоянно?

     

    Вопросец: Какой агрегат обеспечивает наддув подвесных топливных баков для осуществления их выработки?

    Все работает, или все запускается? После запуска, двигатели способны питаться "самотеком". Плюс в этой бете реализован DC Fuel Pump, который включается одновременно с APU. Он может питать APU и левый двигатель.

    "Ткните" носом туда где про самотек написано?

    The aircraft fuel supply system (figure FO-4) consists

    of two internal wing tanks (left and right wing), and

    two tandem-mounted fuselage tanks (left main-aft

    and right main-forward). Up to three external (pylon)

    tanks may be carried; one tank on each wing and one

    on the fuselage centerline. The fuel supply system

    operates as two independent subsystems, with the left

    wing and left main tank feeding the left engine and

    the APU, and the right wing and right main tank

    feeding the right engine. The two subsystems can be

    interconnected by opening crossfeed valves (controlled

    by a single switch in the cockpit) to allow

    pressurized fuel flow to both engines and the APU

    from either subsystem. In addition, the two main

    tanks can be interconnected by opening a tank gate

    valve. The main tank sumps are self-sealing bladder

    cells. Each self-sealing sump contains approximately

    900 pounds of fuel. The upper portion of the cells

    are tear-resistant bladders. The wing tanks are integral

    within the wing structure and do not have

    bladder cells. Foam is incorporated in each tank to

    prevent fuel tank explosion. Boost pressure is provided

    by boost pumps located in each main and

    wing tank. A DC boost pump, located in the left

    main tank is used during engine and APU starts if

    the left main boost pump is inoperative. For negative

    g flight, collector tanks will supply the engine with

    sufficient fuel for 10 seconds operation at MAX

    power. In the event of a main tank boost pump

    failure, the affected engine will suction-feed from the

    failed tank for all power settings up to an altitude of

    10,000 feet (most cases up to 20,000 feet). The wing

    tank boost pumps operate at a higher pressure and

    override the main tank boost pumps to automatically

    empty the wing tanks first.

    The main fuel feed lines to each engine, and to the

    APU, contain shutoff valves that are controlled by

    the fire handles. These shutoff valves allow for isolation

    of the fuel feed system outside the tanks.

    Fuel in the external tanks is transferred to the main

    or wing tanks by pressure from the bleed air system.

    Fuel tank sump drains are provided for each tank.

    Drain valves can be opened externally. Fuel cavity

    drains are provided in each main tank, and protrude

    through the aircraft skin to give an indication of fuel

    cell leaks.

    The wing tanks have a dual-level refueling shutoff

    valve. The valve closes when the tank is full and will

    not reopen unless the fuel level drops approximately

    400 pounds or a time delay of approximately 10

    minutes has elapsed. Wing tanks cannot be topped I off unless the fuel level is below approximately 1,590

    pounds or the fuel manifold has been unpressurized

    for the time delay period. This assures even fuel

    transfer from the external tanks.

    Therefore, during

    fuel transfer from the external tanks, the wing tank

     

    fuel quantity will drop approximately 400 pounds,

    then will fill to capacity. This cycling repeats until

    external fuel is depleted. During air refueling the

    wing tanks will not accept fuel unless the fuel level in

    the tanks has dropped approximately 400 pounds or

    the time delay has elapsed. The total fuel on board

    after refueling could be approximately SOO pounds

    less than total capacity. If total fuel capacity is required

    during air refueling, the external tanks can be

    turned off sufficiently prior to refueling so that the

    wing tank quantity drops approximately 400 pounds

    or the time delay has elapsed.

    A single-point ground refueling receptacle, located in

    the leading edge of the left landing gear nacelle, permits

    refueling of each internal and external tank. A

    control panel, adjacent to the refueling receptacle,

    provides a means of ground checking the refueling

    valve shutoff. The panel also permits selective

    loading of any internal or external tank. Auxiliary

    DC essential bus power is required for refueling valve

    checks, selective tank filling, and to enable external

    tank filling. When the tanks are full the refueling

    valves are closed by a float valve in each tank. Fuel

    tank capacities are shown in the usable fuel quantity

    data table, figure I-S. Fuel grade and specification to

    be used are covered in the servicing diagram, figure

    1-71.

    In addition to features previously mentioned, the

    following survivability features are built into the fuel

    system:

    • Single-point ground refueling and engine feed lines

    outside the tanks are self-sealing to prevent leaks

    • The fuel feed shutoff valves are inside the tanks to

    keep the engine feed lines dry after shutoff

    • Fill disable switches are provided to close off a

    damaged internal tank when air refueling.

    A-10 имеет ADF, но работающий через UHF и VHF радиостанции, что делает его на территории СНГ бесполезным.

    Что делает на территории СНГ А-10С? :)

    А когда появятся, то и привода "подъедут" наверное. Все таки такие объекты в симе нужно ставить через редактор, на усмотрение автора.

     

    Я не особо отслеживаю все сообщения во всех темах: территория Невады будет?

    Если система ILS, то как правило (а тем более на кавказе) - это советские СП-70 или СП-90, работающие в метровом диапазоне. Диапазон длин волн и, соответственно размеры антенн предполагают только стационарное размещение

    Если здесь придерживаться соответствия то и А-10С на этих аэродромах не смотрится. У нас же мы подразумеваем американское присутствие ввиду каких-либо событий.

     

    В ГС2 это было LShift+J

    Спасибо! Не знал.

     

    Это я не знаю, что там в реале, возможно, после праздников кто-то из коллег поделится. Вроде бы стационары, но могу ошибаться.

    Даже если стационарное базирование, то почему не предусмотреть "установку" их в редакторе на любом аэродроме? Ведь монтаж (демонтаж) этого оборудования вполне не сложная задача.

    Или в симе ИЛСы конкретно "привязаны" к четырем аэродромам?

    Пытался вспомнить что давно интересовало и вспомнил. Очень нравится как сделан внешний вид в FSX (MSFS). Там можно сделать не просто статичный вид со стороны, когда камера стоит на одном удалении и положении (Ф2), а как бы вид от плавающей камеры. Что выглядит очень естественно, как будто бы съемка с другого самолета. "Прикрутить" такое можно?

    TACAN и ILS в бете работают, учтите только, что ILS есть только на четырех аэродромах, см. мануал - в нем каналы, частоты и коды.

    Интересует что у них там за оборудование ИЛС? Стационарное или передвижное.

    Наши аналоги ТАКАНА и ИЛС - РСБН и ПРМГ имеют передвижную платформу, проще говоря находятся на шасси. Могут перемещаться своим ходом если возникнет необходимость.

    ТАКАН также, как уже у Вас читал имеет транспортировочные данные. Какое оборудование ИЛС имется у Вас? Если мобильный вид (что у военных в приоритете), то почему четыре аэродрома?

    В полёте я выключил ENG FUEL FLOW, BOOST PUMPS MAIN, BOOST PUMPS WINGS, "летал" минут 20, загонял в отрицательные перегрузки - не глохнут двигатели...

     

    В А-10А так написано (топливная система думаю та же):

     

    AIRCRAFT FUEL SYSTEM

     

    The aircraft fuel supply system (figure FO-4) consists of two integral wing tanks (left and right wing) and two tandem-mounted fuselage tanks (left main-aft and right main-forward). Up to three external (pylon) tanks may be carried; one tank on each wing and one on the fuselage center-line. The fuel supply system operates as two independent subsystems, with the left wing and left main tank feeding the left engine and the APU, and the right wing and right main tank feeding the right engine. The two subsystems can be interconnected by opening crossfeed valves (controlled by a single switch in the cockpit) to allow pressurized fuel flow to both engines and the APU from either subsystem. In addition, the two main tanks can be interconnected by opening a tank gate valve to permit equalization of the fuel in both tanks in level flight. The main tank sumps are self-sealing bladder cells. Each self-sealing sump contains approximately 900 pounds of fuel.

     

    The wing tanks are integral construction within the wing structure and do not have bladder cells. Foam is incorporated in each tank to prevent fuel tank explosion. Boost pressure is provided by boost pumps located in each main and

    wing tank. Also a DC boost pump, located In the left main tank and powered by the DC essential bus, is used during engine and APU starts if the left main boost pump is inoperative. For negative g flight, collector tanks will supply the engine with sufficient fuel for 10 seconds operation at MAX power. In the event of a main tank boost pump failure, the affected engine will suction-feed from the failed tank for all power settings up to an altitude of 10,000 feet (most cases up to 20,000 feet). The wing tank boost pumps operate at a higher output pressure and override the main tank boost pumps to automatically empty the wing tanks first.

    The main fuel feed lines to each engine, and to the APU, contain shutoff valves that are controlled by the fire handles. These shut-off valves allow for isolation of the fuel feed system outside the tanks.

     

    Fuel in the external tanks is transferred to the main or wing tanks by pressure from the bleed air system. Fuel tank sump drains are provided for each tank. Drain valves protrude through structure and can be opened externally. Fuel cavity drains are provided in each main tank, and protrude through the aircraft skin to give an Indication of fuel cell leaks.

     

    The wing tanks have a dual level refueling shutoff valve. The valve closes when the tank Is full and will not reopen unless the fuel level drops approximately 400 pounds or a time delay of approximately 10 minutes has elapsed. This characteristic will not allow the wing tanks to be topped off unless the fuel level is below approximately 1625 pounds or the fuel manifold has been unpres-surlzed for the time delay period. This assures even fuel transfer from the external tanks. Therefore, during fuel transfer from the external tanks, the wing tank fuel quantity will drop approximately 400 pounds, then will fill to capacity. This cycling repeats until external fuel is depleted. During air refueling the wing tanks will not accept fuel unless the fuel level in the tanks has dropped approximately 400 pounds or the time delay has elapsed. The total fuel on board after refueling could be approximately 800 pounds less than total capacity.

     

    If total fuel capacity is required during air refueling, the external tanks can be turned off sufficiently prior to refueling so that the wing tank quantity drops approximately 400 pounds or the time delay has elapsed. Refueling will now fill all tanks to capacity.

     

    A single point ground refueling receptacle, located in the leading edge of the left landing gear nacelle, permits refueling of each internal and external tank. When the receptacle is opened, refueling valves in each tank are automatically opened allowing fuel to enter each tank. When the tanks are full the refueling valves are closed by a float valve In each tank. A control panel, adjacent to the refueling receptacle, provides a means of ground checking the refueling valve shutoff. The panel also permits selective loading of any internal tank or external tank. The panel is deactivated and components restored to the normal flight active position when the door is closed. The refueling valves are powered by the auxiliary DC essential bus. Fuel tank capacities are shown in the usable fuel quantity data table, figure 1-6. Fuel grade and specification to be used are covered in the servicing diagram, figure 1-57.

     

    The fuel system is designed for maximum survivability. Protection provisions are as follows:

     

    • Foam inside and void filler outside of tanks for fire protection.

     

    • Self-sealing main tank sumps. Each sump contains approximately 900 pounds "get home" fuel.

     

    • The main tanks above the sumps are tear-resistant bladder construction.

     

    • Single point ground refueling and engine feed lines outside the tanks are self-sealing to prevent leaks.

     

    • The air refueling line is automatically purged of fuel after air refueling.

     

    • The air refueling purge system can be used to check the integrity of the air refueling line prior to use.

    Моё ИМХО навигация - самое сложное, конечно после выхода русского мануала будет проще, а пока лично я продираюсь через пень колоду... даже ввести маршрут из редактора миссий не могу...:D. Спутник отключается, тыкни HARS на NMSP и будет только ИНС

    С ТАКАНОМ и ИЛСом не знакомился?

    Вопрос: У них "MASTER ARM" это у нас "ГЛАВНЫЙ В"?

     

    Да.

    Под левым дисплеем находится панель управления вооружением. Для подготовки к бою

    включите (переведите вверх) следующие тумблеры: боевой режим (Master Arm),

    лазерный дальномер, стабилизация стрельбы из пушки (GUNPAC – если вы собираетесь

    ее применять), камера целеобнаружения TPG (если она подвешена на самолет):

     

    У нас ГЛАВНЫЙ В включается непосредственно перед самим боевым применением (на боевом курсе). Он выполняет роль предохранителя от случайного нажатия боевой кнопки. Когда самолет подходит к цели летчик уже подготовил систему управления оружием в соответствующее положение. Остается только включить перед маневром атаки ГЛАВНЫЙ В и непосредственно для самой атаки нажать на боевую кнопку.

    Непонятно назначение выключателя MASTER ARM, раз его надо включать перед другими манипуляциями с системой вооружения?

     

    По сути выключатель ГЛАВНЫЙ В это эл. цепь боевой кнопки, как элемент предохранения. На этой же цепи сидят и концевые выключателя шасси, которые блокируют боевую кнопку при выпущенном положении шасси.
