Short video showing AN/ARA-8 functionality. 3 becons are set in mission, two are on ground and one is flying AI plane, each has its morse code and frequency.

What is wrong with radio homing for the D-30? It seems to me that it works as it should.

It is probably not the P-51 bug. A bug with plane shaking was reported for several planes and it seems to be connected with certain weather/wind setting.

You are right, you shouldn't be able to reach 2700RPM with propeller pitch lever fully aft. Propeller pitch remained whole time at 18°, like you did not have el. power for propeller pitch motor. And it seems that you kill your propeller pitch motor's power supply by switching the Ignition switch and the Battery switch in wrong order. You first switched the Ignition switch to BATT position and then the Battery switch to On. It should by vice versa.

Unwanted MAP increasing is caused by sudden the turbo's RPM jump from 2000 to 4000. It happens sometime in some conditions. You can usually set the turbo's RPM in this range too (somewhere between 2000 and 4000), but in this case not... It is probably one from several trouble what the P-47 supercharger has in DCS W. A trigger switches opening waste gate, perhaps due to increasing altitude, but missing steady increase in the turbo's RPM causes your MAP jumps up.

The P-47D does not have a manifold pressure regulator like the Spitfire or the Mustang. So, any speed/altitude change means engine manifold pressure change. The manifold pressure regulator cover these changes in certain range, but planes without it require constant care.

I do not know if it is the reason, but 56inHg without water injection is definitively not correct engine setting. 52inHg is maximal permissible without water injection for fuel what we have in DCS W.

No, you do not need to press (or open) that cover. It is just here.

Controls for L/G are in category SYSTEM. L/G controls are Input.Bf109K4.uc - toggle Input.Bf109K4.uc_0 Input.Bf109K4.uc_1 - for Up/Down and Input.Bf109K4.uc_cover (_cover_0 / _1) - for puschbuttons cover "uc" - as a undercarriage

Unfortunately control names are broken at this moment. If you are looking for axis for R.P.M. control, you are looking for Input.Generic.Pich_slider .

When i loosen button for WI, it will immediately go Off. I must press button for lock WI switch to keep WI On. Then, if i want switch Off WI, i just switch button for the Lock again and it will release WI switch to Off position. D-30 early, i have to keep press button for whole time i want use water injection. No lock here.

In section "Engine Controls" : "Input.P47.nos" will activate water injection and "Input.P47.nos_lock" will lock WI switch in ON position (not for P-47D-30 early) too late..

Blades angles are determined by "limit switches" . It does not matter if commands go from manual or auto, limits are always the same! Feather limit switch is clear, it is written on the blade, value is the same like for maximal angle (high pitch) - 48,5° in our case.

Shouldn`t be use Curtiss Electric C542S? When you read notes in "List of Propellers and Governors ... " about the interchangeable blades for the P-47 there is sentence: "Such procedure (means blade change) also requires a change in blade angles". IMHO, difference between written blade angles on the picture i posted and on the list of propeller is probably because different place where it was measured. Standard was Station 42, but in the list is written Station 54 ... So, 80 degrees (PRP value on INFO BAR) what is possible for the P47 in DCS seems not to be correct. I have no idea where is this value measured in DCS, but if i look on propeller with maximal angle i rather see 80° than 53,5° (or 48,5° ).

Acctualy no. Fuel from the primer line goes to manifold after the carburetor. That is reason why the fuel from the primer line increase richness of mixture.

When you do not lock primer, fuel will run into fuel system and will cause too rich mixture. It resulting in heavy smoke and sometimes fire, IRL. In DCS it does what you wrote..

Do we have interchangeable blades in DCS W? Isn`t this the reason why propeller`s hubs have adjustable blade`s pitch angle range limiters? Different blades, engines ...

It seems that propeller pich above 48,3° is not correct and less than 18,3° . Does not matter if AUTO or MANUAL.

The oil temperature gauge rises up to ambient temperature immediately after battery is switched On, bud soon will fall down to 0°C. Then when i switched batt Off and again switched it On, oil temperature needle remained on 0°C value. Oil temperature rised from 0 only after engine run up. It is on all maps (default weather or edited weather) and all 3 Mustangs. I repaired DCS W and have no mods. Coolant temp. gauge and Carb. temp. gauge are correct. track is included oil temp

Three spawn points are at new airfield on Pagan island in mission editor. They seem to be inactive or whole airfield. It is not possible to use them. If i put plane or helicopter and set it to Takeoff from ramp / Takeoff from parking hot, the plane is moved to nearest active airport spawn point at Saipan Int. Takeoff from RWY is not possible too. Takeoffs from ground/ground hot are the only options for spawn plane at Pagan airfield.

Yes it is. You may use 52inHg/2700RPM for 15 minutes, according to manual. But only if you keep your engine in limits, temperature and pressure. This must be obeyed in all situations, even when engine is idling. You can`t go above limits. btw. 52inHg is attainable at very low altitude without turbo, but only if you fly fast, really fast - 500kph, RAM effect will help you.

This was relevant to only when 91 octane fuel was used. This fuel was used for training units in the USA during WWII. When 100 otane fuel was used, all combat units (this fuel is modeld in the DCS W for Allied planes), interconect could use from ground up to critical altitude. For take-off in this case, pilot should use "take-off stop", it was throttle stop which prevent thottle lever from going above 52inHg MP.

Me neither on default map. Did you try it on map with standard atmosphere? Yes, i have. It was, start from RWY, climb to altitude - measure, climb to next - measure ... ... ...up to 12000m. Full fuel tank (unlimited fuel), empty aux. tank. This table is quite old, but seems to be still valid.

I did, i just expected that the difference between maximal power and special emergency power is clear, i will try to be more specific in future to avoid such confusion. Actually it does not matter, IMO the DCS K-4 is still slightly optimistic (above critical altitude) even with special emergency power setting. I guess, all here knows that. But, we unfortunately do not have something better. And moreover, ED never released what is base for their power/performance for the 109. These calculations were usually rather accurate. And still, you do that.

1. i know that ... 2. DCS K-4 at 9000m, 2600RPM - 690+kph, 2800RPM - 705+ kph (WITHOUT MW50) 3.well what?
