That looks very much like AcesHigh updating the aircraft's position incorrectly. I would bet that the p51 pilot in reality rolled left and pushed the nose down causing one of those negative G rolls.
I agree with this...today in game I saw a similar thing happen...he did a split S but on my end it stuttered randomly to the point I saw his entire plane pointing vertical...ended with me colliding him because I thought he was going up instead of down...unfortunately, not filming at the time.

Word is that after the collision, Junky palmed his forehead and said, "Wow I could have had a V8".

Here is the event, and this is why I want ah films because I can extract data.

I really do not know what you expect but   scrubbing 65mph in 2 secs is a fairly rapped deceleration177.

That deceleration scrubbed about 53% of your energy in 2 secs.

The starting altitude was 400ish, the ending altitude was 400ish...the "zoom" portion was doing the 90 nose high to 90 out from velocity vector to 60 nose low....most of which was planform to the wind.

Obviously in your world no problem...

Carry on...nothing to see here..FLS has said this is normal flight behavior. :bhead

Watching the film in slow motion the entry is at 230 at about 400 and the aircraft recovers at over 600 feet at 180. 50 mph loss going uphill. Assuming the Spitfire he is flying stalls at 85 MPH, it would require 7.3 G's to achieve an accelerated stall at 230 mph (Required to enter the snap roll) Stall speed equals 1 G stall speed times square root of the G. 230 is 2.7 times 85 which equals 7.3 G required to stall at an indicated speed of 230 mph.

So, what we have is the ability to rack on 7.3 G's, snap roll the aircraft uphill and recover after only losing about 20 % of the entry airspeed.

Putting aside the incredibly violent stresses on pilot and air frame during such a maneuver, there seems to be something a little fishy about the above math.

Of course, such things are nearly impossible to quantify. No one does such things in real life.

You don't need 7g, you only need one wing to exceed the stall AOA.

Note he didn't recover at 600 ft, he stabilized there and recovered to level flight around 440 ft.

Here is the event, and this is why I want ah films because I can extract data.
Max yaw Angle off the vel vector is 64.2 not as you say almost 90.


Cool look into the simulation. Yaw AOA? I am assuming that is essentially yaw.

I know roll is around the axis of motion, but I am curious if the plane in the data ever went inverted.

Assuming the Spitfire he is flying stalls at 85 MPH, it would require 7.3 G's to achieve an accelerated stall at 230 mph (Required to enter the snap roll) Stall speed equals 1 G stall speed times square root of the G. 230 is 2.7 times 85 which equals 7.3 G required to stall at an indicated speed of 230 mph.

I have never seen this equation. Is this airfoil specific?

It's been posted in help and training a few times.  Knowing the stall speed at any g load let's you estimate the load factor at the stall at other speeds.

240 to 175 in 2 secs =53% of my Energy? :)


And question on the numbers...you saying the yaw AOA is measured off the velocity vector?  Because once I get the aircraft moving its all relative at that point....

But this picture is taken from the film....Start, max deviation from flight path observed, and recovery...External, fixed camera view.  Sure looks 90ish to me...

But bottom line, is thank you for the detailed replies and the fact that you care enough to answer the post(s). 

Now to work on refining my snap roll defense... :banana:

The velocity vector is the relative wind that defines AOA. The numbers posted show the actual angles. Your flight path wasn't straight so a fixed camera view and still picture creates an illusion. Turn trails on in film to see it better.

Note he didn't recover at 600 ft, he stabilized there and recovered to level flight around 440 ft.

So how exactly do you stall a wing with a 1 G stall speed of 85 mph at 230 mph?

Please tell me. I would love to know.

And "recovery" from a stall is when you aint stalled no more and that happened above 600 feet.

I wait with bated breath.

So you are applying enough yaw force to move the longitudinal axis fast enough and far enough across the velocity vector to blank the wing enough to stall it at the tip?

The force required to do that at 230 mph is tremendous.

In reality, the airfoil needs to be close to its critical AOA before a rudder kick will stall it (a little up aileron will help on the side of the kick) and the speed needs to be low enough that the rudder kick doesn't knock the tail off.

Snap rolls are violent things, involving high G on the wing and large forces on the vertical stabilizer. You have to stall (or get very very close) the wing with back stick and induce the autorotation with rudder or it is just a high G barrel roll.

And this is where I will bow out.

There is no room for a point of view other than "it matches reality now" so no point in further discussion.
