Dropping Flaps??

[1Boner]

I've poked around a bit and can't seem to find anything that tells me the speed that I can drop flaps in any particular plane.

Is there a chart somewhere?

Or is it trial and error.

[VonMessa]

Mostly error. 

[Nilsen]

Mostly error.

Roll a plane with full flaps, slowly accelerate, stop acceleration each the flaps sound, note the speeds.

[BaldEagl]

Most American planes drop the first notch about 250 mph, German @ 175, British @ 150.  I think Russian and Japanese are around 150 too IIRC.  These are just general guidlines and could still vary by aircraft.

[Motherland]

For Germans...
Fw190 Flaps pop out at 180-90ish, Bf109 flaps at 200.
In the Fw190 there're two or three notches to half, and then at 150 the last notch of flaps comes out.

I think the first notch of flaps in the 262 come out at 300-400mph.

[MjTalon]

First notch of flaps come out in a P47 & P51 up to 400IAS

[Wingnutt]

P40E flaps come out at over 360 and for 2 turns or so it will stick with anything.

[moot]

IAS speeds:
190A5, A8, D9, F8, 152:  180, 160, 140 (140mph notch is a whole half of the flap range)

109E4: 200, 198, 175, 150 (4 notches)
All other 109s: 195, 185, 175, 165, 155.

Both Me110s: 200 (three first notches), 175, 150.
Me262, 163: 400, 275, 225, 180, 165.

are they gonna address the disparity ?

[Scherf]

Wouldn't think so, those speeds probably come from pilot's notes.

[thorsim]

pretty sure they are inaccurate ...

the 109 had a flap wheel so it was pilot torque that actuated the flaps, so it seems that if one could crank them down to 50-60 degrees at 140 mph they should be able to be deployed 1-20 degrees much faster than 200 mph ...

the 190 had low degree flap settings as well i believe these could be adjusted as well since there was a flap indicator tab at the top of the wing so the pilot could visually confirm his flap state,  seems oddly redundant if the flap settings were fixed.  also the same argument as ...
if 60 degrees of deflection is possible at 140 mph then the system should be able to manage a 8-10-20 degree deflection at much higher speeds than 180.

i would like to see some data that explains why the AH physics are different for american combat flaps as opposed to everyone else's combat flaps.  real world flap deployment speed limits would be nice as well so AH can show its thinking here.

as it stands the 190s can't drop their flaps to any degree until they are slow enough to drop their landing gears, pretty silly really.

That flap wheel was like turning a jack to raise up a car, takes a ridiculous number of turns just to get 20 degrees down.

so then there is a lot of torque for the pilot to deploy them at higher speeds.  not sure why you would want a combat flap setting higher than 20 degrees anyway.

i mean 60 degrees of flaps are not a combat configuration because of the drag ...

most planes have very little room between large flap deflection speeds and their stall limits.  any combat in that type of configuration would be "short lived" with a pretty obvious result. 

if that is not the case in the game then there is much more wrong with the flaps than just the relative deployment speeds, don't ya think?

[Anaxogoras]

In our game, to really succeed in some knock-down scissors fights you have to be prepared to drop full flaps and raise them up again in a number of seconds.  I don't know about other aircraft, but this would have been impossible in the Bf 109:

Now, let's not hijack this into another "realism" thread, I was just observing...
