Efficient climbing? - tarnsman - 16.03.2009

I have some bad habits ive picked up over the years which are really hurting me flying the BF-109 in my campaign. Chief among these is efficiently gaining altitude. I really dont know what im doing so I will stop here and ask for guidance.
P.S I use CEM.
Thanks

Hi'
The 109 was known for it's steep angle of climb so I would think you should keep 220-250 KM/pH indicated air speed , for best angle of climb (depending on weight of course).

Doing here some test pilot stuff... try a level tight turn at the same power you intend to climb. Do not loose any altutude while turning... take note of the minumum speed at wich you can mantain that altitude while turning.

Then use that very same airspeed as your climb speed, it should be Vy, best rate of climb speed ... or really really close to it, ... with the available excess power.

It works for every aircraft... but do not forget to use superchargers when available and test flight at several altitudes to change speed (usually the higher the slower Vy).

For a Bf.109G, Vy should be about 170 MPH

Good luck.

hi there i tend to open combat flaps and give full throttle the climb is nice and progressive and is constant hope that helps(':wink:')

- GADGET - 17.03.2009

Sorry, but you definitely should NOT drop flaps for climbing. The best rate of climb is attained in clean configuration, always, as the L/D ratio is better.

I'm not a fulltime 109jock, but someone on UBI once posted a vid of the 109 spiralclimbing to gain height and keep the advantage in a DF.

Unfortunately; could not find it anywhere on the net anymore Sad

From what I recall, is keeping the speed around 210-220 and keep an eye on the engine temperature. This for both a normal climb and a spiralclimb.
Do not add any flaps unless really needed, but my experience is that combat flaps only slows you down - so I only use those to recover or make a "saddle"-kill. But feel free to experiment with them.

Do work your radiator manually though, cooling is vital, especially in a long spiralclimb.

Good luck! Smile

Im better with a spiral climbing but i climb at a speed between 210 - 230 just like most people say in this topic, im not sure if thats the best way ''and angle''

Spiral climb: (bf-109 G-2 fuel 25%)
When you release your controls the 109 will climb by itself, The engine torgue pushes the airplane left. When this happens push the stick a ''little'' bit back. and turn in the direction of the torgue.
In the control F-1 view position the attitude indicator shows you can easily climb at the top line of it. The airspeed stays between 200 - 230 km you can use your flaps when you're having problems keeping this speed. I use this spiral a lot when chased most people can not keep up.

Thanks for the feedback guys.

Gadget, by level turn I assume you mean wings level and no aileron?

Also, should I not use any elevator input? what about elevator trim?

Do you guys use auto prop in the 109, If so what power setting 100% or is 80% better. Im looking for sustained climb setttings to obtain the best tactical advantage in the least amount of time without overheating.

Also is there a combined wisdom thread on the 109 in IL2?
Thanks again.

Climb setting: 2600rpm, 1.30ata.The most favourable climb speed is 270km/h (from G2 handbuch).

Level turn means a normal turn on an horizontal plane, aka at constant altitude.

Please also check any lectures about curves of available and required power for climbing

Gadget makes a very good suggestion with his "level turn" trick for finding your climb speed.

And yes, for the record, kicking down your flaps is a very, very bad idea, especially if you've already engaged an enemy - even if you think you've shot him down or lost him. I think I've used flaps as a last-ditch way to gain altitude on a few occasions, though, where it was either gain altitude or die; one said instance was when I wandered near an enemy airfield after my entire flight had been shot down, and found myself in the midst of several groups of enemy fighters - it didn't matter how fast I was moving, if I was seen I was dead.

So, flaps bad, knowing your climb attitude and speeds, good.
