[kampf]

Very good!
but i think you missed:

next and previous bomb salvo quantity

toggle bomb short delay

[Muffin]

Always good to have the emergency gear release set as well :thumbsup:

[DRock]

Yes, I did.

Thanks Guys.:thumbsup:

Can someone PLEASE tell me when and how to use the emergency undercarriage system?

[GERMANWOLF]

Mixture???what??

Can someone PLEASE tell me when and how to use the emergency undercarriage system?

When you are damaged or engine has seized and you hit the gear down button and the red lights stay on (gear isn't moving) hit the emergency undercarriage system button or pull the handle under the gear selector. This will mechanically release the gear and allow the air stream to start pulling your gear down. The hand pump (repeated presses) may or may not assist in getting them down (green lights) depending on damage.

Does it also work when you take damage and your gear comes down?

If you mean will it put your gear back up? Then no, it is only a last ditch effort to get your gear down. Even if you have taken some damage and/or your engine is wind-milling, there is a good chance your gear will come down as the engine is still creating some hyd pressure. If there is no hyd pressure, this mechanically releases the gear so they can come down.

Makes sense, thanks!

[9./JG52 Hans Gruber]

I made this a long time ago. The pump handle is definitely required to bring the wheels down. That might not have been its historical function but that is how it is in clod.

Thanks Grubs, will come in handy next time it happens :D

Thank you for this.

Hey guys,

Does the standard E-4 model have WEP, or is that just the E-4N?

[Incog]

E-4 has WEP, E-4/N also has WEP. It's the E-4/N-derated that doesn't have WEP, afaik

[3./JG51_Heiden]

I guess I'm confused on what it's supposed to do. When I press the WEP button, the throttle simply goes to 100% position (1.3 ATA). Why can't I just manually move it there myself? I thought the point of WEP was to give you a power setting that exceeds the range of normal throttle operation. The most I can get out of the E-4 is 1.3 ATA. This is correct, yes?

[Incog]

perhaps you have two controls mixed up, e.g.

i'm sure WEP engages when I need it (E-4 goes to 1.4 Ata)

^"Backspace" is the command that gives me my WEP.

not sure what else could be wrong

Maybe due this:

On Controls are two commands related to WEP - exclusive for German planes.
Notice that these commands dont work in the same way for all Bf 109, Bf 110 versions, varies accord version. (1)

TOGGLE WAR EMERGENCY POWER - this command turn on WEP (allow 1.4 ATA), that work for ~1 minute, them automatically turned off, is need wait ~30 seconds to use again.
Hit the key/button assigned for the command before the one minute expiry dont turn the WEP "off" .

And

THROTTLE WAR EMERGENCY POWER - this command instantly moves[/B] the in game throttle lever to 100% (dont allow 1.4 ATA), independent of joystick throttle position.

- Hit the key/button again dont "reset" the (in game) throttle for the previous position, or the joystick throttle position.
- But move slight the joystick throttle reset the in game throttle for the actual joystick throttle position. And due this, if joystick axis is fault - spiking, the command can be reset unexpectedly.

* This command can be assigned to joystick throttle axis (just assign a key together with the axis to differentiate from the power control), but what the difference in move joy' throttle to 100%?:

In resume, seem not well implement/unfinished command...

But work for Incog. :)

(1) Here all Bf 109 and Bf 110 respond to command Throttle WEP - what give me the same ATA if use joystick throttle - why I dont see poin in use this on key/button. :D
Toggle WEP work for all BF 109 versions minus E-4/N Derated and for Bf 110 C-4/N (at least the "HUD" show the message "WEP: ON").

[3./JG51_Heiden]

Oh wow! I have been flying around without using WEP correctly for some days now. I can't even imagine the situations I could have avoided by having the extra 1.4 ATA available. Thanks guys!!

[III./ZG76_Saipan]

wonder what your rad settings are...they can help also....water 75-100% oil 30-80% seems pretty common...

[3./JG51_Heiden]

I keep the oil cooler at 75% for climb, 50% for cruise, and modulate when egressing. For water, 75%-ish for climb, 50% for cruise, and again modulate to avoid overheating when egressing.

i am new with CoD, so i hope this is the right place to ask:

i just searched in the wiki about bf109 E4, so i need some help:



"Engine
DB 601 A-1 with Neuem (“new”) Supercharger, Full Throttle Height = 4500 m @ 1.30 ata/2400 rpm"
====> does it mean we need to use the supercharger if hugher than 4500 ?



"on ground
RPM[U/min] pressure[ata]
Emergency power = 1' 2500 1,40
Short power = 5' 2400 1,30
Increased cont. power = 30' 2300 1,23
max. cont. power = d 2200 1,15
econ. power 1500 0,75


===> the info above:
- does it mean there is a Mathematical relation between RPM & ATA ?
- may you tell me the meaning of:
- short power / increase cont. power and max. cont. power and the minutes related to them ?

thank you very much for your help

[hnbdgr]

keep oil at 25% at all times you will never ever overheat.
water 25% only if your speed is over 500

well i am still new on CoD, so just to better understand: the 109E4 throttle goes already to "110%" as it was in 109's IL2-1946 ? if yes, the Toggle War Emergency Power comes on top of that 110% ?

[hnbdgr]

throttle goes to 100%, WEP is activated separately for one minute at a time only with a minute cooldown and increases the engine load to 1.4 or more ATA (different engines), That is how it is in-game, not sure what the mechanism was in RL.

[blackshark]

may you please alaborate on the "bombing" commands ? the meaning and how to use them ?
or if you can give me links on bombing training ?

[=FI=Murph]

I have run across many references to settings for radiators but nothing about controlling rpms using prop pitch settings. I know that the boost (ATA) settings for the various versions of the 109 need to be respected, but what prop pitch settings are experienced 109 jockeys using?
I am quite used to using the constant speed prop in the Merlin powered aircraft, where you set pitch to get a certain rpm setting and basically leave it there. The German aircraft seem to be quite a bit more complicated, in that you might set pitch to get a certain rpm in level flight, but diving the plane using the same pitch setting will cause an over-rev. I have been trying to get to know the 109 lately and always seem to end up with an oil slick on the windscreen, even with both rads set full open and the ATA set at recommended boost. I use full fine pitch for takeoff (12 o'clock) and set between 11:30-10:00 for most other flight conditions,but I still seem to end up blowing the engine every time.
I do understand that the E4 has auto rpm, but I would like to learn to fly the other versions as well.

[ATAG_kiwiflieger]

Here's what I use for most 109s excepting the E4N/DeRated (in which one can go full throttle all day):

Unlimited cruise setting: 1.25 ATA, 2300-2400 RPM (can go up to 2600 when above 6K)

My 'never exceed' limit: 2700 RPM

I normally either throttle down or keep a good eye on my RPMs in a dive or else one very quickly ends up with a shaky plane (if you're lucky), governor failure (in which manipulating the prop pitch no longer works), and/or oil on your wind screen. Overrevs is the number one cause of me (and I bet a lot of other people too) blowing the engine on a 109.

[=FI=Murph]

So, what's the procedure? Set ATA first using throttle, then rpm using prop pitch?

[RAF74_Buzzsaw]

So, what's the procedure? Set ATA first using throttle, then rpm using prop pitch?

Typically you set ata first, but as you adjust rpm, the ata will rise of fall depending on whether you are increasing or decreasing rpms.

So further adjustment is necessary.

[Vlerkies]

So, what's the procedure? Set ATA first using throttle, then rpm using prop pitch?

A bit of both depending on the situation, sometimes together.
Cruising around set optimum ata and adjust rpm with pp. As speed changes this requires constant attention if flying manual pp.
In a DF you will need to adjust with throttle as well as the pitch wont respond fast enough on its own, especially in a dive which will result in a overrev, so cut back on the throttle accordingly as you gather speed or reach a point where the pp can't cope.


Its pretty easy and you get used to the engine note eventually, its a good indicator.
