?Luft Auto Prop Pitch...

[gn728]

Hey all  - I'm just curious about the automatic pitch in Luft AC and the Drehzahl switch, when it would be used etc. In general is it left in auto and switched to manual, for say take offs and landings, or switched all the time in flight depending on the situation? And within BOX - is auto fine for needs? ... Thanks....

The German engine can manage itself better than a human can - it is better left in auto.

 

The Drehzahl switch on the Anton throttle was typically there only if the Kommandogerat was damaged - as a way to set prop pitch manually to get home and land the plane.

I think technically manual mode 12:00 should be used to startup and taxi.

I put it into manual mode 12:00 for landings as well (from downwind on),

I believe that is also textbook. I noticed if I'm gentle with the throttle I don't need to switch it out of auto for taxi or landing because it stays in the fine position.

When the early Gustavs still had the Engine limited to 2600 RPM the Pilots would manually increase RPM to 2800 and more above 6500m, which increased Critical Altitude somewhat, thus allowing for more Speed to chase down High flying Bombers and Fighters.

As far as I know, G2 can be manually pushed to 2850RPM for around 2 or 3 minutes.

Yes and you gain good amount of speed.

Spoiler

left lineis on auto, and right line is gain on manual :

 

Also on G14 and K4s going to ~2600rpm on deck will gain you some ~5-10kmh on speed compared to auto

My question would be is that historic though?  Some of these gamer settings like this seem like they would be just as likely ruin the engine in real life as would to give some extra speed.

 

10kmh/6 mph is actually a lot of speed - I don't remember reading about a late war Luftwaffe pilot using manual pitch to increase deck speed like this, but I could be wrong (?) Maybe it is historic - just doesn't seem like it.

[CountZero]

Who knows, i just noticed it works in game like that.

On the German side, i didn't read anything. The Russians tho, did push their P-40 and P-39's well past the US allowed settings, at the expense of engine life. They would change engines after four, five combat sorties.  But this was done following orders from above, after extensive testing. It was not something that pilots did on their own.

Sorry for necro, been away for a while.

 

It adds you a few meters per second climbrate as well. It saved my sweet rudder from those pesky Yaks and Spits trying to helicopter me.

[Lusekofte]

In theory what increace the rpm? Is it  propsettings? If so, would it not be less effective in fast speed level flight? Would it not be better with a more effective prop pitch at highest possible ata

You have to love German engineering - the first "limp home mode"!

Similar controls an be found in american airplanes - prop switches from auto to manual (increase / decrease).

Nothing fancy.

[Hartigan]

I've noticed landing with FW 190 is way easier with manual mode 12.15- 12.30 rpm . Take off with auto mode

[1./JG42Nephris]

Depending on how it was developed,  the recommendations of the origiginal plane manuals are valid.

That means you can check/search www for Luftwaffe  manuals and follow the recommendations depending on the situation you got to dela with.

E.g. ingame you can squeeze a bit more from the FW190 A5  in "Steigflug" by using manual mode with values from the org. manual.

However in combat, you dont want to deal with prop pitch as you got other prio topics in that situations, like checking six and/or your oponents´ maneuvers

I am so glad to reas this. I always wondered why the auto coexisted with a manual, less effective system. 

[UFA_Bagel]

Manual pitch or rpm may simplify taxi if you increase pitch or reduce rpm as it allows you to work with throttle in wide range without accelerating too much and initiating a ground loops. Especially useful for Spit. Now I am not using it for this and just being gentle enough with throttle.

The duck greatly benefits from manual prop pitch

[Stryker07]

Yea the Hs-129 is the only reason i have keys bound for luft manual prop pitch. Its almost impossible to cruise without it

[Soilworker]

Well the Hs-129 is supposed to be flown with manual prop pitch when not in combat. 

[GOA_Karaya_VR]

Under certains situations, i use to cut to 100+ Pitch , ( minus amount of rpm ) and cut throttle power, when i descent in a very vertical angle for a boom and zoom attack ( plus 30% of flaps ) that allows me a flat descent to the target and help me to avoid overshoot the enemy and always be on the 6 of the enemy.

 

Another example is in a rolling scissors , i cut rpm and throttle , put some flaps and let the enemy overshoot me. 

 

I use those methods in Bf109 and Fw190.

Any specific values or pointers to the manual page? Thank you!
