Aircraft Type: Ju 87 B-2
System affected: Cockpit label
Description of the problem:



Typo in cockpit labeling. Currently it's Kraftstoffrat but it must be Kraftstoffvorrat.....

According to this picture it should be "Kraftstoffrest"

Yes, it could be, but it is a B-1.
I just wrote it, because the "Kraftstoffrat" may be abbreviation instead of misspelling.

Aircraft type: Messerschmitt Bf 109 E-1, E-3, E-4

System affected: Water Cooling system
Description of the problem: In the real aircrafts, the Water Cooling system have overpressure valve, prevent of the overpressure causes damage on the system. If i dont open radiator in the game, the cooling system boils (it's ok), and damaged (it's not ok). The valves in the front-top positions. The pilot immediately notice if the steam burst out.

Description of proper operation: The coolant leaves the system only for the time while in an excess pressure. There is no permanent damage (except for the loss of coolant).

[JG53Frankyboy]

Aircraft type: Ju88A-1

System Affected : Propellersystem

Description of the problem :
the CoD Ju88A-1 has a Constanst Speed Propeller unit. Thats would be correct for later versions, but not for the A-1.

It should have a manual variable propeller system (like the ingame Bf109E-1/-3 and Bf110C-4-/-7) with an additional 'automatic' setting, that would keep the rpm at 2350, used for start and dive.

Aircraft type: Messerschmitt Bf 109 E-1, E-3, E-4

System affected:Warning sounds

Description of the problem: The 109 was a safety device: In the case where the Flap is open, but the Langing Gear is not, a horn (E11 - "Boschhorn") warn the pilot. As the old Il-2-it worked well, now completely missing. Not only the later models, the "E" also was equipped with it.

Aircraft Type: Bf 110 C-4 / C-7
System affected: Elektrischer Wendehorizont (Artifactical Horizon): On/Off switch
Description of the problem:

The horizon device isn't switched on by standard but will be used only when needed. Its lifetime is very short when be used constantly so the pilots regularly left the horizon shut off.

When switched on a special generator did start wich could be heard very clearly. Check this video to get a sound sample:

Aircraft Type: Spitfire mk1/1a/2a
System Affected: Fuel Gauge
Description of the Problem:

Currently, the fuel Gauge in the above mentioned Planes isn´t working, showing always full tanks, making very long flights bit of a gamble.

Edit: Ok, nevermind, its working, thanks banks.

It is working. It only shows the last 40% as it only measures the 37 gallons of the bottom tank and not the 48 gallons of the top tank. The attached screenshot shows 25% fuel.

This is not true I am afraid. The fuel gauge is showing only the bottom tank in a Spitfire which is correct for a Mk.IIa model. (it even says so on the instrument!)

The issues regarding the fuel gauges / fuel system in Spitfires are as follows:

Aircraft Type: Spitfire Mk.I, Mk.Ia, Mk.IIa
System Affected: Fuel System
Description of the Problem:

Early Spitfires marks modelled in the sim have had 2 fuel tanks with one fuel cock each:



There were 2 fuel cock levers operating respective fuel cocks:



Left hand side was TOP TANK (48 gallons), right hand side was the BOTTOM TANK (37).

As modelled in game (single fuel cock) is later Mk.V.



-----------------------------------------------------------------------------------------

Aircraft Type: Hurricane Mk.I, Spitfire Mk.I, Mk.IIa
System Affected: Fuel System (Fuel gauges)
Description of the Problem:

Fuel gauges are incorrect in both function and appearance.

Hurricanes have a Spitfire's 37 gallon instrument installed:



This is what it should have:



Spitfire Mk.IIa has got the correct instrument (37 gallon) showing the bottom tank only (correctly), but in normal conditions, the gauge should read zero. Reading has been obtained by pressing the button as shown. (Only then, with the button pressed, the needle would move and show the amount of fuel left in the respective tank. It would obviously move back to zero when pilot released the button).





Spitfire Mk.I (and Mk.Ia) did in fact have 2 fuel gauges in this starboard side of the cockpit - one calibrated to 37 gallons for the bottom tank (right hand side), next to it on the left was identical instrument calibrated to 48 gallons. Both operated via button as described above, e.g. reading such as TAIL ON GROUND or LEVEL FLIGHT were identical, scale have had different reading due to different calibration - 0 5 10 15 20 30 40 48 on the top scale (rather that 0 5 10 15 25 30 37) and 0 5 10 20 30 40 48 on the bottom scale (rather than 0 5 10 20 30 37). There was obviously no alloy label above the 37 instrument.

Layout visible here on a early example (iron gunsight and manual gear lever):

If i dont open radiator in the game, the cooling system biols (it's ok), and damaged (it's not ok). The valves in the front-top positions. The pilot immediately notice if the steam burst out.

Aircraft type: Spitfire

System affected: Same as the above quote.

Proper operation: Same as the above quote. There is a pressure relief valve in front of the cockpit, on the right side of the nose.

Of course, in both cases if the coolant is left boiling for too long and the valve remains open, then the amount of coolant will decrease too much and overheating will occur.



Aircraft type: He-111P

System affected: Compasses

Description of problem: The magnetic compass on the starboard cockpit wall is displaying the tooltip correctly when mousing over with the cursor, but the actual animation is bugged (you need to mouse over to get a heading, you can't do it just by looking at it). The other compasses show the correct tooltips, but the 3D instruments are reversed. For example, when flying a heading of 90 the repeater compass either shows 270, or the course setter is aligned the opposite way (need to test this out because i can't exactly remember right now, if someone remembers tell me and i'll edit my post)



Aircraft type: All Luftwaffe aircraft with autopilots

System affected: Gyrocompass (DG) and autopilot (AP)

Description of problem: Normally, to keep level the pilot will align the "heading to hold" readout with the DG's readout and then engage the AP. In the sim however, the aircraft turns until it settles at an offset of about 9 degrees between the two. For example, if the DG shows 90 degrees and i want to engage the AP and stay level, i need to set the desired heading to 99 degrees. I don't know if this is a bug or a realistic limitation of the system.



Aircraft type: He-111H, possibly the other Luftwaffe bombers too (He-111P, Ju-88 )

System affected: Lofte bombsight

Description of problem:

a) The bombsight is calibrated wrong in terms of airspeed units when calculating the release point. Using the correct data results in the bombsight tracking the aiming point correctly once automation is engaged, however the bombs release way too early and miss. After personally testing it, i can confirm what the people who fly on ATAG say: the bombsight treats airspeed inputs as mph instead of km/h and that's why it releases earlier and misses. Converting airspeed to mph (divide the km/h by 1.6) and using that value in the bombsight gives a correct release time, but then the sight tracks too fast and the aim point moves to the bottom of the sight: the player has to periodically turn off automation, place the crosshairs on the target again (with the bombsight increase/decrease distance keys) and re-enable it.

This is all because the bombsight tracking treats airspeed inputs correctly as km/h, but the release point calculations treat airspeed units as mph.

b) The on-screen text readouts don't display all the intervals for altitude. It is possible to set the sight at 10 meter intervals, but the text only displays hundreds. So for example, when adjusting the sight altitude you see repeating scrolling messages of
1400
1400
1400
1500
1500

instead of

1470
1480
1490
1500
1510


c) The markings on the bombsight reticule seem wrong, they definitely work different than they did in IL2:1946. In 46, a release point is calculated based on player inputs of altitude and TAS and a yellow triangular marker is moved around on the circular scale around the crosshairs to reflect the release point's position/distance. Then, when automation is engaged a second marker moves from up the scale towards the bottom as the bombsight tracks the target. When the two markers coincide the bombs are released. In CoD however, even when the bombs are aimed correctly and score hits (using the workaround described above), the release always occurs when the marker is at the 9 o'clock position of the crosshairs: it seems that the marker moves at variable speed and the release point location is constant on the scale, instead of the other way around. Also, two bombs always release last when the marker reaches the bottom of the scale and this could be related to the following, final issue.

d) In the He-111 it's not possible to set the bomb series size for all bombs when carrying 32 SC50s. The maximum setting available is 30 bombs. The Ju88 doesn't suffer from this, because it also has an "unlimited" setting for bomb series.



P.S. Great job on this thread. Apart from correcting the spelling mistakes which is purely an immersion/historical correctness issue, it also helps identify problems with systems and these matter a lot during actual gameplay. Keep up the good work everyone
