You are quite right, it shouldnt, which is why it was fixed in later version of the Birtish fighters. But this is a factual known issue with these planes due to the lack of direct fuel injection, which when put into negative g's cause the fuel to be forced out of carb.

Now whether this effect in game is too much or too little is something I have no clue on judging.....

Where is Miss Shilling's orifice when you need it

Miss Schiiling didn't have an orifice at the time of BOB

Oh I bet she did!!!

[Osprey]

It was introduced during the BoB afaik.

S!

And how about this? "Miss Shilling with a small team travelled around the countryside in early 1941 fitting the restrictors, giving priority to front-line units. By March 1941 the device had been installed throughout RAF Fighter Command."

Dairy.air is well aware that it is a factual issue, which is why he is using real life facts (he flies a cessna with a carburreter fed engine) to suggest that the negative g cutout is not modelled correctly.

[DairyAir]

Precisely.

I.M.H.O.
As indicated in several charts of the time period.
The cut-out should not occur until the aircraft reaches -.9G.
Not as it is now, where the slightest nose down, causes an instant cut-out.
Accompanied by an equally unrealistic airspeed drop. Mass and Momentum of the Aircraft damp this Airspeed loss down considerably in real life.

2 cents Eh!

As posted the Actual documented figure is Neg G effects commence at +0.1G that is a 0.9G decrement from 1G flight. What we NOW have in Ver 1.08 is pretty close to the mark.

If you are not running Ver 1.08 you will be seeing the Old value that was way to sensitive.

WRT to Dates. The Schiling orifice didnt come into service until Post BOB. The graphic below comes from the UK National Archives document AVIA 13/234. The image is the first page of this file and is a covering minute to the file. As you can see its dated 21St Feb 1941. This document is the source document with measured G onset values of the cut as well. As can be seen even in the covering minute the values of +0.1 ---> 0g is quoted. This has all been debated (and proven) in numerous debates on this forum over the last 12 months.

I stand corrected.

IvanK is correct, Ver. 1.08, does in fact feel pretty good.
