    It would be a nice feature to disable it entirely on the Ju-87.

    Dive brakes and trimmers on the right side of elevator linked by hydraulic line, an there is no valves in this hydraulic line. And electrical part of dive system - electromagnet and spring in the trimmer control - "blocked" with the bomb drop system, and can be turned off only with it.

    They didn't use the dive recovery system this late in the war. 

    Do you have any document, mentioned that dive system is can be turned off some kind?

    I release air brakes and it switchs automatic to dive, right?

    Yes. Trimmer set to "nose heavy".

    Then I drop bombs.. 

    Or retract air brakes (at Ju-87). And...

    And now:

    It help me to recover from the dive or do it by itself?

    ...trimmer set back to default position, so airplane become "tail heavy" and it is help to recover from dive.

    Well, they did put the first satellite in space, and the first man.

    Of course, we put the first man in orbit, and the first man on the moon. (Debatable amongst some people, I know... :P)

    The first flight into space was the first orbital flight.
    Therefore, Gagarin was both the first man in space and the first in orbit.
    Flight of A. Shepard (second flight into space) was suborbital.

    @ZachariasX The P-51 would still work ok with the current implementation. If i'm correct currently in the P-40 and P-47 the fuselage auxiliary tank is the last one to fill up when selecting fuel amount, and the first one to be emptied when operating the plane.

    Yes. In case of P-51 - 100% of fuel - wing tanks and fuselage tank are full. ~68% of fuel - fuselage tank is empty, wing tanks are full.

  5. When you fly below 3000 ft at combat or WEP mode, check throttle lever position and MAP. If you move throttle past take-off stop position, MAP more that 52 inch (or 64 at WEP mode).

    About critical altitude.

    From P-47D-28 model specification:

    Critical altitude is 24500 ft. Ingame - 23000 ft, 5% error. Not best result, but acceptable.

    The P-47D-22 report:

    It is good reference. Data from this report correlate well with data from "model specification" at 64 inch MAP (+-10 mph). Also it is corellate well with ingame P-47 at 52 inch MAP (ingame top speed 407 mph at 29500 feet and 410 from report).

    I'm doing something wrong?

    Probably. Ingame top speed is 700 kph TAS (485 IAS) at 7000m.

  7. In various tests from various references, the weight of the aircraft was mainly about 13,000 pounds.
    For example, from different references (from wwiiaircraftperformance):

    NACA stability and control tests of P-47D-30 - gross weight 12810 ... 11870 pounds,

    P-47D-10 43-75035 - 13244 pounds,

    P-47D      42-26167 - 13230 pounds,

    Comparison of P-47D-30, P-47M and P-47N Performance - 12731 pounds.

    Where did you come to the conclusion that it was using only 50% of it's total fuel? Just curious 

     

    With 8 guns and 50% fuel in simulator gross weight of P-47 is 13220 lb.
    It is near to gross weight from model specifications of P-47D-28  - 12958 lb - with 6 guns and 205 gals of fuel.
    If you chose this variant ingame (205 gals - 55%), you has gross weight 13025 lbs. The difference appears in general due to the fact that in the simulator only one version of the filling with oil (full tank). In reality, dressing with oil could also be partial.
    But 50% of the fuel and 8 machine guns - just easier to remember and advise to use.

  9. Reference for P-47D-28 top speed:

    2.jpg.212a7a2f599854aa427bdfe25ddff34a.jpg

     

    Check top speed at standart atmosphere, +15C temperature and 760 mm.hg pressure AGL. In quick mission - on autumn maps.

     

    Airplane - 50% of fuel, 8 guns, standart ammunition. 64 inch MAP, 2700 rpm, auto rich mixture (80% of lever), cowl flaps and oil cooler flaps closed, intercooler flaps - neutral (50%).

    Question: Does the D-28 have an internal throttle regulator overriding the throttle and turbo setting (which I doubt) or do we see an artifact, namely the MAP dial reflecting actual power output?

     

    When you turn on water injection switch on throttle lever:
    - water solenoid valve opens,
    - water pressure actuaters boos re-set mechanism, which connected to turbosupercharger control unit (you can see at external wiev hov exhaust manifold wastegates moves),
    - mixture leaner valve opened.

    So, MAP increased by turbosupercharger, and it is not a bug.

    I think it is supposed to go past a gate as described here, but this movement past the gate doesn't seem to be modeled. 

     

    If you mean take-off stop - it is modelled. At ground level, with prop pitch control fully forward at 2700 rpm  you has 52 inch manifold pressure at approx. 95% of throttle lever position - it is take-off stop position. At altitudes above ~3000ft. - you has 52 inch manifold pressure with all interconnected controls at prop pitch lever position according 2700 rpm (full forward).

  11. Here we mentioned the report, which says about the speed of 530 km / h at the ground and 610 at an altitude of 5800 m.
    Yes, we have this report. However, the notes in this report refer to the unsatisfactory quality of this particular aircraft (problems with cracking of the skin and paint, defects in the sealing of  engine cowling are noted).
    At the same time, the characteristics of seven other serial aircraft significantly differ for the better (although they are not identical to each other).
    Therefore, in this case, averaging the characteristics, considering a deliberately defective aircraft - will not be a "gold middle". And the average characteristics of serial aircraft are directly given in the report, which I showed above.

  12. I'm afraid of upsetting someone, but the serial La-5FN in 1943 really had very good characteristics. Despite the numerous quality problems, it was a good aircraft with a good engine.
    For confirmation, I quote from the report on the testing of serial aircraft in 1943 year. I draw your attention, these were tests of serial aircraft, without any special modifications. The tests passed seven La-5 FN of different series, from May to December 1943. In general, the aircraft showed similar results:
    The maximum speed at the ground level is an average of 578 km / h. (from 570 to 587 km / h). In the simulator - 583 km / h, in the range.
    The maximum speed of 6 km is an average of 634 km / h (from 629 to 640 km / h). In the simulator - 646 km / h, only 1% faster.
    So in the simulator La-5FN speed it is quite consistent with the test data of serial aircraft.
